Getestet am: WordPress 3.0.1

Mit diesem Code können Sie das Logo der WordPress-Anmeldeseite sowie den href-Link und den Titeltext dieses Logoseinfach ändern.

 add_filter( 'login_headerurl', 'namespace_login_headerurl' );
/**
 * Replaces the login header logo URL
 *
 * @param $url
 */
function namespace_login_headerurl( $url ) {
    $url = home_url( '/' );
    return $url;
}

add_filter( 'login_headertitle', 'namespace_login_headertitle' );
/**
 * Replaces the login header logo title
 *
 * @param $title
 */
function namespace_login_headertitle( $title ) {
    $title = get_bloginfo( 'name' );
    return $title;
}

add_action( 'login_head', 'namespace_login_style' );
/**

 */
function namespace_login_style() {
    echo '<style>.login h1 a { background-image: url( ' . get_template_directory_uri() . '/images/logo.png ) !important; }</style>';
}
 

BEARBEITEN: Wenn Sie das Site-Logo als Ersatzfür das Login-Logo verwendenmöchten,können Sie diese Informationen wiefolgt dynamisch abrufen (getestetin WP3.5 ). :

 function namespace_login_style() {
    if( function_exists('get_custom_header') ){
        $width = get_custom_header()->width;
        $height = get_custom_header()->height;
    } else {
        $width = HEADER_IMAGE_WIDTH;
        $height = HEADER_IMAGE_HEIGHT;
    }
    echo '<style>'.PHP_EOL;
    echo '.login h1 a {'.PHP_EOL; 
    echo '  background-image: url( '; header_image(); echo ' ) !important; '.PHP_EOL;
    echo '  width: '.$width.'px !important;'.PHP_EOL;
    echo '  height: '.$height.'px !important;'.PHP_EOL;
    echo '  background-size: '.$width.'px '.$height.'px !important;'.PHP_EOL;
    echo '}'.PHP_EOL;
    echo '</style>'.PHP_EOL;
}
 

Modify the Login Logo & Image URL Link

Tested on: WordPress 3.0.1

This code will allow you to easily modify the WordPress Login page Logo as well as the href link and title text of this logo.

add_filter( 'login_headerurl', 'namespace_login_headerurl' );
/**
 * Replaces the login header logo URL
 *
 * @param $url
 */
function namespace_login_headerurl( $url ) {
    $url = home_url( '/' );
    return $url;
}

add_filter( 'login_headertitle', 'namespace_login_headertitle' );
/**
 * Replaces the login header logo title
 *
 * @param $title
 */
function namespace_login_headertitle( $title ) {
    $title = get_bloginfo( 'name' );
    return $title;
}

add_action( 'login_head', 'namespace_login_style' );
/**

 */
function namespace_login_style() {
    echo '<style>.login h1 a { background-image: url( ' . get_template_directory_uri() . '/images/logo.png ) !important; }</style>';
}

EDIT: If you want to use the site logo to replace the login logo, you can use the following to dynamically pull that information (tested on WP3.5):

function namespace_login_style() {
    if( function_exists('get_custom_header') ){
        $width = get_custom_header()->width;
        $height = get_custom_header()->height;
    } else {
        $width = HEADER_IMAGE_WIDTH;
        $height = HEADER_IMAGE_HEIGHT;
    }
    echo '<style>'.PHP_EOL;
    echo '.login h1 a {'.PHP_EOL; 
    echo '  background-image: url( '; header_image(); echo ' ) !important; '.PHP_EOL;
    echo '  width: '.$width.'px !important;'.PHP_EOL;
    echo '  height: '.$height.'px !important;'.PHP_EOL;
    echo '  background-size: '.$width.'px '.$height.'px !important;'.PHP_EOL;
    echo '}'.PHP_EOL;
    echo '</style>'.PHP_EOL;
}

Entfernen Sie die Update-Benachrichtigungfür alle Benutzer außer ADMIN-Benutzer

Getestet am: WordPress 3.0.1

Dieser Code stellt sicher,dass keine anderen Benutzer als "admin" werden von WordPressbenachrichtigt,wenn Updates verfügbar sind.

 // REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
   global $user_login;
   get_currentuserinfo();
   if ($user_login !== "admin") { // Change admin to the username that gets the updates
    add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
    add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
   }
 

Die Version wurde sogeändert,dassnur Aktualisierungsbenachrichtigungenfür Administratorbenutzer angezeigt werden (im Gegensatznurfür den Benutzer 'admin'):

 // REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
       global $user_login;
       get_currentuserinfo();
       if (!current_user_can('update_plugins')) { // Checks to see if current user can update plugins
        add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
        add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
       }
 

Remove Update Notification for all users except ADMIN User

Tested on: WordPress 3.0.1

This code will ensures that no users other than "admin" are notified by WordPress when updates are available..

    add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
   }

Changed version to only show update notification for admin users (as opposed to just the user 'admin'):

// REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
       global $user_login;
       get_currentuserinfo();
       if (!current_user_can('update_plugins')) { // Checks to see if current user can update plugins

& quot; Wordpress & quot;entfernenzu & quot; WordPress & quot;Filter

Getestet am: WordPress 3.0.1

Mit WordPress Version 3.0 wurdeein Filter hinzugefügt,der automatisch alle Instanzen von "Wordpress" konvertiert.(kein Großbuchstabe P) zu "WordPress"(miteinem Großbuchstaben P)in Post-Inhalten,Post-Titeln und Kommentartext.Einige Leute sehen dies als aufdringlich an,aberichmuss WordPress von Zeit zu Zeitfalschinterpretieren undfand den Filteretwasnervig.

 // Remove annoying P filter
if(function_exists('capital_P_dangit')) {
    foreach ( array( 'the_content', 'the_title' ) as $filter )
        remove_filter( $filter, 'capital_P_dangit', 11 );

    remove_filter('comment_text', 'capital_P_dangit', 31 );
}
 

Remove "Wordpress" to "WordPress" filter

Tested on: WordPress 3.0.1

There was a filter added with WordPress version 3.0 that automatically converts all instances of "Wordpress" (no capital P) to "WordPress" (with a capital P) in post content, post titles, and comment text. Some people see this as intrusive, but I just have a need to mis-case WordPress from time to time and found the filter somewhat annoying.

// Remove annoying P filter
if(function_exists('capital_P_dangit')) {
    foreach ( array( 'the_content', 'the_title' ) as $filter )
        remove_filter( $filter, 'capital_P_dangit', 11 );

    remove_filter('comment_text', 'capital_P_dangit', 31 );

Enable Error Debugging And Logging To Use On Live Sites

This is a piece of code I wrote to make use of the WP_DEBUG constants that are normally disabled by default. Well, I created a way to not only enable WP_DEBUG so you can use it on a live site with no negative side-effects, but I also made use of the other debugging constants for forcing errors to be displayed, and for creating a log file of the errors and Notices in the /wp-content directory.

Drop this code in your wp-config.php file (AFTER YOU SAVE A BACKUP JUST IN CASE) and then you can pass the ?debug=1, 2, or 3 parameters at the end of any URL on your site.

?debug=1 = shows all errors/notices ?debug=2 = forces them to be displayed ?debug=3 = creates a debug.log file of all errors in /wp-content dir.

}

I go into more detail on the guest post I wrote for Comluv if you're interested, here: http://comluv.com/dev/enable-debugging-and-logging-for-live-site-usage/

I'm still working on a way to make this either password protected, or preferrably somehow make it work on if (current_user_can('manage_themes') and is_logged_in().

But that's where it gets alot more tricky.

Neue Rollen und Funktionen - Nureinmal ausführen!

Ich halte diesegriffbereit,diesist der richtige Weg,um sie ohne Plugin zumachen. Sie legenein einzelnes Feld (prefix_user_roles)in der Optionsdatenbankfest,und Siebenötigen kein Plugin,um siefestzulegen. Auf der Codex-Seitefinden Sieeine Liste der verfügbaren Funktionen und Beschreibungenihrer Funktionen. Sie Siemüssennureinen dieser Blöcke auskommentieren,eine Seite laden und sie dannerneut kommentieren! Hiererstelleicheine Rollemit den Funktionen,dieichbenötige:

 /* Capabilities */

// To add the new role, using 'international' as the short name and
// 'International Blogger' as the displayed name in the User list and edit page:
/*
add_role('international', 'International Blogger', array(
    'read' => true, // True allows that capability, False specifically removes it.
    'edit_posts' => true,
    'delete_posts' => true,
    'edit_published_posts' => true,
    'publish_posts' => true,
    'edit_files' => true,
    'import' => true,
    'upload_files' => true //last in array needs no comma!
));
*/


// To remove one outright or remove one of the defaults:
/* 
remove_role('international');
*/
 

Manchmalistespraktisch,eine vorhandene Rolle hinzuzufügen/daraus zuentfernen,anstatteine zuentfernen underneut hinzuzufügen. Siemüssenesnur auskommentieren,eine Seiteneu laden und dannerneut kommentieren. Dadurch wird die Rolle/Funktion ordnungsgemäßin der Optionstabellegespeichert. (Auf diese Weise können Sie als Entwickler sie steuern und den Overhead der umfangreichen Pluginsentfernen,die dasselbetun.) Hier ändereich die Autorenrolle,umihre veröffentlichten Beiträge zu löschen (Standardeinstellung),erlaubeihnenjedoch die Möglichkeit zum Bearbeitenihre veröffentlichten Beiträge (wasfür diese Rolle standardmäßignichtmöglichist) -mit * add_cap * oder * remove_cap *.

 /*
$edit_role = get_role('author');
   $edit_role->add_cap('edit_published_posts');
   $edit_role->remove_cap('delete_published_posts');
*/
 

Ichbehalteeine Tabellemit dem Raster von der Codex-Seitefür Websites,die auf diese Weisegeändert wurden,damitichmich daranerinnern kann,wie die Dingeeingestellt sind,obwohl das Auslassen des auskommentierten Codesin Ihrer Dateifunctions.phpfunktioniert. Lassen Sie diese Beispielenicht unkommentiert,da sie sonstbei jedem Laden der Seitein die Datenbankgeschrieben werden!

New Roles and Capabilities - Only run once!

I keep these handy, this is the right way to do them without a plugin. They set a single field (prefix_user_roles) in the options database, and you don't need a plugin to set them. Refer to the Codex page for a list of what capabilities are available and descriptions for what they do. You only need to uncomment one of these blocks, load any page and then comment them again! Here I'm creating a role that's got the capabilities I need:

/* Capabilities */

// To add the new role, using 'international' as the short name and
// 'International Blogger' as the displayed name in the User list and edit page:
/*
add_role('international', 'International Blogger', array(
    'read' => true, // True allows that capability, False specifically removes it.
    'edit_posts' => true,
    'delete_posts' => true,
    'edit_published_posts' => true,
    'publish_posts' => true,
    'edit_files' => true,
    'import' => true,
    'upload_files' => true //last in array needs no comma!
));
*/


// To remove one outright or remove one of the defaults:
/* 
remove_role('international');
*/

It's sometimes handy to add/remove from an existing role rather than removing and re-adding one. Again, you only need to uncomment it, reload a page and then comment it again. This will store the role/capability properly in the options table. (This allows you, the developer to control them and removes the overhead of the bulky plugins that do the same thing.) Here I'm changing the author role to delete their published posts (the default), but allowing them the capability to edit their published posts (which isn't possible for this role by default)-- using *add_cap* or *remove_cap*.

/*
$edit_role = get_role('author');
   $edit_role->add_cap('edit_published_posts');
   $edit_role->remove_cap('delete_published_posts');
*/

I keep a spreadsheet with the grid from the Codex page for sites that modify this way, so I can remember how things are set, though leaving the commented out code in your functions.php file will work to. Don't leave these examples uncommented, or it will write to the database with each page load!

Autoren-Metabox/Optionenentfernen & amp; Gehen Sie zur Veröffentlichung der MetaBox

Getestet am: Wordpress 3.0.1

Eines der Dinge,diemich verrücktmachen,istein überfüllter Wordpress-Verwaltungsbereich. Eines der Elemente,dieichjetztimmer von Anfang anin meiner Dateifunctions.phpeinrichte,ist das Entfernen der Autoren-MetaBox und der Bildschirmoptionen und das Hinzufügen der Option zur Veröffentlichungsmetabox. Meiner Meinungnachmacht daseinfach Sinn und hält die Dinge sauber. Diesgilt auchfürgeltende Berechtigungen.

Um dieses Ziel zuerreichen,kopieren Sieeinfach denfolgenden Code undfügen Sieihnin Ihre Dateifunctions.phpein.

Wenn Sie der Meinung sind,dasseseinen besseren Weggibt,schlagen Sie diesbitte vor.

HINWEIS: AKTUALISIERT DEN CODE,UM EIN CODIERUNGSFRAGE ZU BEHEBEN

 // MOVE THE AUTHOR METABOX INTO THE PUBLISH METABOX
add_action( 'admin_menu', 'remove_author_metabox' );
add_action( 'post_submitbox_misc_actions', 'move_author_to_publish_metabox' );
function remove_author_metabox() {
    remove_meta_box( 'authordiv', 'post', 'normal' );

}
 

Remove Author Metabox/Options & Move to Publish MetaBox

Tested on: Wordpress 3.0.1

One of the things that drive me crazy is a cluttered Wordpress Admin area. One of the elements which I now always setup from the start in my functions.php file is removing the Author MetaBox and Screen Options and then adding the option into the publish metabox. In my opinion this just makes sense and keep things clean. This also respects applicable permissions.

To achieve this goal, just copy and past the following code into your functions.php file.

If you feel there is a better way of doing this please suggest.

NOTE: UPDATED THE CODE TO FIX A CODING ISSUE

// MOVE THE AUTHOR METABOX INTO THE PUBLISH METABOX
add_action( 'admin_menu', 'remove_author_metabox' );
add_action( 'post_submitbox_misc_actions', 'move_author_to_publish_metabox' );
function remove_author_metabox() {
    remove_meta_box( 'authordiv', 'post', 'normal' );
}
function move_author_to_publish_metabox() {
    global $post_ID;
    $post = get_post( $post_ID );
    echo '<div id="author" class="misc-pub-section" style="border-top-style:solid; border-top-width:1px; border-top-color:#EEEEEE; border-bottom-width:0px;">Author: ';
    post_author_meta_box( $post );
    echo '</div>';
}

Server schnellbestimmen & amp; Umgebungsdetails

Wenn Siemehrere Server undmehrere Umgebungen wie Entwicklungs-,Qualitätssicherungs- und Produktionsumgebungen haben,kann dies sehrnützlich sein.

Beimeinen Systemen wird die Umgebung durch dieersten drei Buchstaben des Hostnamensbestimmt. Dies kannjedoch leicht an Ihre Anforderungen angepasst werden.

 add_action( 'admin_notices', 'report_environment_status', 3 );

// Report on which server and environment details
function report_environment_status() {
    $server = php_uname('n');
    switch (strtolower(substr($server,0,3))) {
        case 'pXX':
            $msg = "PRODUCTION";
            break;
        case 'qXX':
            $msg = "QA";
            break;
        case 'dXX':
            $msg = "DEVELOPMENT";
            break;
        default :
            $msg = 'UNKNOWN';
    }
    echo "<div id='update-nag'>";
    echo "<b>You are in the $msg environment. (Server: $server)</b>";
    echo "</div>";
}
 

Dies hatmich viele Male davorbewahrt,Aktualisierungenin derfalschen Umgebung vorzunehmen.

Sie können dies auchin ein Plugin verwandeln und das Netzwerk aktivieren,damit alle Sites die Benachrichtigungerhalten.

Quickly Determine Server & Environment Details

If you have multiple servers and multiple environments such as development, QA, and production environments, this can be very useful.

For my systems, environment is determined by the first 3 letters of the hostname, but this could easily be changed to whatever suits your needs.

add_action( 'admin_notices', 'report_environment_status', 3 );

// Report on which server and environment details
function report_environment_status() {
    $server = php_uname('n');
    switch (strtolower(substr($server,0,3))) {
        case 'pXX':
            $msg = "PRODUCTION";
            break;
        case 'qXX':
            $msg = "QA";
            break;
        case 'dXX':
            $msg = "DEVELOPMENT";
            break;
        default :
            $msg = 'UNKNOWN';
    }
    echo "<div id='update-nag'>";
    echo "<b>You are in the $msg environment. (Server: $server)</b>";
    echo "</div>";
}

This has saved me many times from making updates to the wrong environment.

You can also turn this into a plugin and network activate it so all sites get the notification.

Remove XML-RPC when not in use for performance boost

Tested on: Wordpress 3.0.1

WordPress uses a CURL operation to test for SSL capability for XML-RPC. If you're using XML-RPC but not using, then you can remove the filter. This is a small performance boost (since basically WP does a cURL GET on the https url and either 1) gets a denied message, or 2) times out, and it can take upwards of 5 seconds), but in our case it actually prevented a gateway timeout where a proxy was timing out before the cURL GET was timing out rendering XML-RPC unusable.

    if ( $echo == false ) 
        return $custom_field;

}
 

Rufen Sie dann das Feldmit einereinzelnen Zeile

Grab all custom fields globally

function get_custom_field($key, $echo = FALSE) {

    if ( $echo == false ) 
        return $custom_field;
    echo $custom_field;
}

Then call the field with a single line

<?php get_custom_field('custom-field-name', TRUE); ?>

Gibt die Anzahl der Kommentare zurück

Diesentspricht count_user_posts(),gibt jedoch stattdessen die Anzahl der Kommentare zurück:

 function count_user_comments($id) {
global $wpdb;
$users = $wpdb->get_var("
        SELECT COUNT( * ) AS total
        FROM $wpdb->comments
        WHERE comment_approved = 1 
        AND user_id = $id");
return $users;
}
 

Mehr: Anzahl der Beiträge des Benutzers (einschließlichbenutzerdefinierter Beitragstypen) oder Kommentare:

 function atom_count($user_id, $what_to_count = 'post') {
  global $wpdb;    
  $where = $what_to_count == 'comment' ? "WHERE comment_approved = 1 AND user_id = {$user_id}" : get_posts_by_author_sql($what_to_count, TRUE, $user_id);
  $from = "FROM ".(($what_to_count == 'comment') ? $wpdb->comments : $wpdb->posts);    
  $count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) {$from} {$where}"));
  return $count;
}
 

Verwendungsbeispiele:

<?php echo atom_count(1, 'movie'); // displays 'movie' post type count ?>

<?php echo atom_count(1, 'comment'); // displays comment count ?>

Return the number of comments

This is like count_user_posts(), but returns the number of comments instead:

function count_user_comments($id) {
global $wpdb;
$users = $wpdb->get_var("
        SELECT COUNT( * ) AS total
        FROM $wpdb->comments
        WHERE comment_approved = 1 
        AND user_id = $id");
return $users;
}

More: Count User's posts (including custom post types) or comments:

function atom_count($user_id, $what_to_count = 'post') {
  global $wpdb;    
  $where = $what_to_count == 'comment' ? "WHERE comment_approved = 1 AND user_id = {$user_id}" : get_posts_by_author_sql($what_to_count, TRUE, $user_id);
  $from = "FROM ".(($what_to_count == 'comment') ? $wpdb->comments : $wpdb->posts);    
  $count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) {$from} {$where}"));
  return $count;
}

Usage examples:

<?php echo atom_count(1, 'movie'); // displays 'movie' post type count ?>

<?php echo atom_count(1, 'comment'); // displays comment count ?>

Post Word Count

Tested on: Wordpress 3.0.1

(Originally extracted from the Post Word Count plug-in by Nick Momrick)

Adds a count of total published words to the bottom of the "Right Now" box on the admin dashboard. Useful if you're using your blog as an outlet for something like NaNoWriMo or if you just want to keep track of how prolific your blogging skills have become.

function post_word_count() {
    $count = 0;
    $posts = get_posts( array(
        'numberposts' => -1,
        'post_type' => array( 'post', 'page' )
    ));
    foreach( $posts as $post ) {
        $count += str_word_count( strip_tags( get_post_field( 'post_content', $post->ID )));
    }
    $num =  number_format_i18n( $count );
    // This block will add your word count to the stats portion of the Right Now box
    $text = _n( 'Word', 'Words', $num );
    echo "<tr><td class='first b'>{$num}</td><td class='t'>{$text}</td></tr>";
    // This line will add your word count to the bottom of the Right Now box.
    echo '<p>This blog contains a total of <strong>' . $num . '</strong> published words!</p>';
}

// add to Content Stats table
add_action( 'right_now_content_table_end', 'post_word_count');
// add to bottom of Activity Box
add_action('activity_box_end', 'post_word_count');

Kudos to Rarst for the query-free cleanup of the code!

    wp_print_scripts('my_script');
}
    return $posts;
}
add_action('the_posts', 'has_my_shortcode');
 

Und hiererfahren Sie,wie Sie Skriptenur laden,wennein bestimmtes Widget vorhandenist

Um das Skript auf der Seite zu laden,auf dernur das Widgetgeladenist,müssen Sie den Codeis_active_widget ()in Ihre Widget-Klasseeinfügen. Siehebeispielsweise das Standard-Widgetfür aktuelle Kommentare (wp-includes/default-widgets.php,Zeile 602):

 class WP_Widget_Recent_Comments extends WP_Widget {
    function WP_Widget_Recent_Comments() {
        $widget_ops = array('classname' => 'widget_recent_comments', 'description' => __( 'The most recent comments' ) );
        $this->WP_Widget('recent-comments', __('Recent Comments'), $widget_ops);
        $this->alt_option_name = 'widget_recent_comments';
        if ( is_active_widget(false, false, $this->id_base) )
        add_action( 'wp_head', array(&$this, 'recent_comments_style') );
        add_action( 'comment_post', array(&$this, 'flush_widget_cache') );
        add_action( 'transition_comment_status', array(&$this, 'flush_widget_cache') );
    }
 

Loading scripts conditionally

Here is a way to load scripts only if a particular shortcode or widget is present. source: Loading scripts only if a particular shortcode or widget is present

function has_my_shortcode($posts) {
    if ( empty($posts) )
        return $posts;
    $found = false;
    foreach ($posts as $post) {
        if ( stripos($post->post_content, '[my_shortcode') )
            $found = true;
            break;
        }
    if ($found){
        $urljs = get_bloginfo( 'template_directory' ).IMP_JS;
    wp_register_script('my_script', $urljs.'myscript.js' );
    wp_print_scripts('my_script');
}
    return $posts;
}
add_action('the_posts', 'has_my_shortcode');

And here is how to load scripts only if a certain widget is present

To load the script in the page where the widget is loaded only, you will have to add the is_active_widget() code, in you widget class. E.g., see the default recent comments widget (wp-includes/default-widgets.php, line 602):

class WP_Widget_Recent_Comments extends WP_Widget {
    function WP_Widget_Recent_Comments() {
        $widget_ops = array('classname' => 'widget_recent_comments', 'description' => __( 'The most recent comments' ) );
        $this->WP_Widget('recent-comments', __('Recent Comments'), $widget_ops);
        $this->alt_option_name = 'widget_recent_comments';
        if ( is_active_widget(false, false, $this->id_base) )
        add_action( 'wp_head', array(&$this, 'recent_comments_style') );
        add_action( 'comment_post', array(&$this, 'flush_widget_cache') );
        add_action( 'transition_comment_status', array(&$this, 'flush_widget_cache') );
    }

Benutzerdefiniertes Dashboard-CSS

 /* Change WordPress dashboard CSS */
function custom_admin_styles() {
    echo '<style type="text/css">#wphead{background:#069}</style>';
}
add_action('admin_head', 'custom_admin_styles');
 

Sie können zwischen den Tags Änderungen am CSS hinzufügen.

/* Change WordPress dashboard CSS */
function custom_admin_styles() {

    echo $excerpt;
}
 

Begrenzen Sie die Länge des angezeigten Auszugs,indem Siein das Thema schreiben: Auszug ('20 ');

        $embed = preg_replace( '/param>/', 'param><param name="wmode" value="transparent" />', $embed, 1);
    }
    return $embed;
}
 

Ich hattein der Vergangenheit Probleme,bei deneneingebettete Flash-Objektemit Dropdown-Navigationsmenüs kollidieren. Dieser Filterbehebt dieses Problem,indem den Einbettungenein transparenter Fenstermodus hinzugefügt wird.

Entfernen Sie die Spalte "Kommentare" aus der Liste der Admin-Seiten

function custom_pages_columns($defaults) {
    unset($defaults['comments']);
    return $defaults;
}
 

Ichbenutze kaum Kommentare zu Seiten und dies hilft,die Dingeim WordPress-Dashboard aufgeräumt zu halten.

Add parent page slug to body_class

/***************************************************************

    if (is_page()) {
        if ($post->post_parent) {
            $parent  = end(get_post_ancestors($current_page_id));
        } else {
            $parent = $post->ID;
        }
        $post_data = get_post($parent, ARRAY_A);
        $classes[] = 'section-' . $post_data['post_name'];
    }
    return $classes;
}

This filter adds a unique body class based on the highest level parent of the current page. I use this for sites that have specific colours or layouts for each section of the site. It works best with sites based around pages. CSS examples:

.section-about { background: red; }
.section-portfolio { background: blue; }

Your theme must also make use of the body_class function.

Fix oEmbed flash objects

/***************************************************************
* Function my_oembed_wmode
* Fix oEmbed window mode for flash objects
***************************************************************/

add_filter('embed_oembed_html', 'my_oembed_wmode', 1);

function my_oembed_wmode( $embed ) {
    if ( strpos( $embed, '<param' ) !== false ) {
        $embed = str_replace( '<embed', '<embed wmode="transparent" ', $embed );
        $embed = preg_replace( '/param>/', 'param><param name="wmode" value="transparent" />', $embed, 1);
    }
    return $embed;
}

I have had problems in the past where oEmbed Flash objects collide with drop down navigation menus. This filter fixes that problem by adding a transparent window mode to the embeds.

Remove the "comments" column from Admin page list

/***************************************************************
* Function custom_pages_columns

function custom_pages_columns($defaults) {
    unset($defaults['comments']);
    return $defaults;
}

I hardly ever make use of commenting on pages and this helps keep things tidy in the WordPress dashboard.

Check if a post has embedded content.

Check if a post has embedded content, works inside the loop using the current post's ID, or alternatively can be passed an ID to determine the post to check for embedded content.

function has_embed( $post_id = false ) {
    if( !$post_id ) $post_id = get_the_ID();
    else $post_id = absint( $post_id );
    if( !$post_id ) return false;

    $post_meta = get_post_custom_keys( $post_id );
    $post_meta = array_map( 'trim' , $post_meta );

    foreach( $post_meta as $meta ) {
        if( '_oembed' != substr( $meta , 0 , 7 ) )
            continue;
        return true;
    }
    return false;
}

You'd use the function in the same way you check if a post has a tag..

if( has_embed() ) {
   // do whatever
}

Function returns true if an embed is found, false on fail.

Beiträge von verschiedenenbenutzerdefinierten Beitragstypen auf der Startseite anzeigen

Wenn Sie denfolgenden Code am Ende dieses Beitragsin Ihre Dateifunctions.phpeinfügen,können Sie WordPress dazubringen,automatisch Beiträge von verschiedenenbenutzerdefinierten Beitragstypen anzuzeigen,die Sieerstellt haben. Derzeit zeigt WordPress standardmäßignur Beiträge an,die zu den Standard- "Beiträgen"gehören. Beitragstyp.

Imfolgenden Beispielmüssen Sie den Abschnitt ändern,der Folgendes aufruft:

 $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
 

Mit Ihreneigenen benutzerdefinierten Beitragstypen,die Siein die Ergebnisse der Homepage-Beitragsliste aufnehmenmöchten. In diesem Fallbitten wir WordPress,uns alle Beiträge zurückzugeben,die zum Standard- "Beitrag"gehören. und & quot; Seite & quot;post_typefordert WordPress dann auf,auch denbenutzerdefinierten Beitragstyp anzugeben,den wirfür "Dienste"erstellt haben. und schließlich der Standard-WordPress-Post-Typ "Anhang". Diesbedeutet lediglich,dassjedes Mal,wennetwas zur Medienbibliothek hinzugefügt wird,es automatisch als separater Eintrag auf der Startseite angezeigt wird.

 // CUSTOM HOMEPAGE POST LIST INCLUDING DIFFERENT POST_TYPES
// make sure to edit the post types you wanted included in the list below
add_filter( 'pre_get_posts', 'my_homepage_post_list' );
function my_homepage_post_list ( $query ) {
    if ( is_home() && false == $query->query_vars['suppress_filters'] )
        $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
    return $query;
}
 

Sie können diesebenutzerdefinierte Abfrage auch an verschiedenen Speicherorten verwenden,z. B.in einembenutzerdefinierten Feed über soetwas

 if (( is_home() && false == $query->query_vars['suppress_filters'] ) || is_feed())
 

Display Posts from Different Custom Post Types on homepage

By dropping the following code on the bottom of this post into your functions.php file you can get wordpress to automatically display posts from different custom post types you have created. Currently by default wordpress only display posts which belong to the default "posts" post type.

In the example provided below you will need to change the section which calls:

$query->set( 'post_type', array('post', 'page', 'services', 'attachment'));

With your own custom post types which you would like to include in the homepage post list results. In this case we are asking wordpress to return to us all posts belonging to the default "post" and "page" post_type then asking wordpress to also include the custom post type we created for "services" and finally the default wordpress post type of "attachment" which just means that anytime something is added to the media library it will automatically get displayed on the homepage as a separate entry.

// CUSTOM HOMEPAGE POST LIST INCLUDING DIFFERENT POST_TYPES
// make sure to edit the post types you wanted included in the list below
add_filter( 'pre_get_posts', 'my_homepage_post_list' );
function my_homepage_post_list ( $query ) {
    if ( is_home() && false == $query->query_vars['suppress_filters'] )
        $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
    return $query;
}

You can also utilize this custom query in different locations, such as in a custom feed through something like this

if (( is_home() && false == $query->query_vars['suppress_filters'] ) || is_feed())

Entfernen Sie die Standardfelder des Benutzerprofilsfür Kontaktinformationen undersetzen Sie sie durchetwas Benutzerfreundlicheres.

Der zweite Teil dieser Funktion wurdebereits obenerwähnt,aber das Entfernen der Standardfelder - AIM,Yahoo IM und Jabber/Google Talk -nochnicht:

 function update_contact_methods( $contactmethods ) {

// Remove annoying and unwanted default fields  
unset($contactmethods['aim']);  
unset($contactmethods['jabber']);  
unset($contactmethods['yim']);  

// Add new fields  
$contactmethods['phone'] = 'Phone';  
$contactmethods['mobile'] = 'Mobile';  
$contactmethods['address'] = 'Address';  

return $contactmethods;
}
add_filter('user_contactmethods', 'update_contact_methods');
 

Natürlich können Sie unter "Neue Felder hinzufügen"

Remove default fields contact info user profile and replace them with something more usable

The second part of this function has already been mentioned above, but removing the default fields - AIM, Yahoo IM and Jabber/Google Talk - not yet:

function update_contact_methods( $contactmethods ) {

// Remove annoying and unwanted default fields  
unset($contactmethods['aim']);  
unset($contactmethods['jabber']);  
unset($contactmethods['yim']);  

// Add new fields  
$contactmethods['phone'] = 'Phone';  
$contactmethods['mobile'] = 'Mobile';  
$contactmethods['address'] = 'Address';  

return $contactmethods;
}
add_filter('user_contactmethods', 'update_contact_methods');

Of course you can add as many fields as you want (see previous examples earlier in this thread) under "Add new fields"

Vorbelegung von Beitragstypen

Hieristeine für diese Sammlung.

 ////////////////////////////////////////////////////////////////////////////////////
// This auto populates post types and posts.
///////////////////////////////////////////////////////////////////////////////////

add_filter( 'default_content', 'my_editor_content' );

function my_editor_content( $content ) {

    global $post_type;

    switch( $post_type ) {
        case 'your_post_type_here': //auto populate
            $content = 'The content you want to pre-populate the post type with.';
break;
     }

    return $content;
}
 

Dies kannnützlich sein,wenn Sie dieselben Informationenmit geringfügigen Unterschiedenimmer wieder veröffentlichenmüssen.

Pre-populating post types

Here is one for this collection.

////////////////////////////////////////////////////////////////////////////////////
// This auto populates post types and posts.
///////////////////////////////////////////////////////////////////////////////////

add_filter( 'default_content', 'my_editor_content' );

function my_editor_content( $content ) {

    global $post_type;

    switch( $post_type ) {
        case 'your_post_type_here': //auto populate
            $content = 'The content you want to pre-populate the post type with.';
break;
     }

    return $content;
}

This can come in handy for when you need to post the same info over and over again with slight differences.

Google Analytics-Code automatischeinschließen

Getestet am: Wordpress 3.1 RC3

Ich verwende dieses Skript seit WordPress 2.3.0 auf allenmeinen Websites. Esfügt lediglich die Standard-Google-Tracking-Skripte zur Fußzeile hinzu.

 // Add Google Analytics Tracking Code
function add_google_analytics() {
?>
<script type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
    document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
    try {
        var pageTracker = _gat._getTracker("UA-XXXXXXX-X");
        pageTracker._trackPageview();
    } catch(err) {}</script>
<?php
}

add_action('wp_footer', 'add_google_analytics');
 

Ersetzen Sie UA-XXXXXXX-X unbedingt durch Ihreneigenen Google-Tracking-Code ...

Auto Include Google Analytics Code

Tested on: Wordpress 3.1 RC3

I've been using this script on all of my sites since WordPress 2.3.0 ... it just adds the standard Google tracking scripts to the footer.

// Add Google Analytics Tracking Code
function add_google_analytics() {
?>
<script type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
    document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
    try {
        var pageTracker = _gat._getTracker("UA-XXXXXXX-X");
        pageTracker._trackPageview();
    } catch(err) {}</script>
<?php
}

add_action('wp_footer', 'add_google_analytics');

Just be sure to replace UA-XXXXXXX-X with your own Google tracking code...

Fügen Sie dem TinyMCE-Editorbenutzerdefinierte Stile hinzu

Manchmal sind Benutzer und Kunden verwirrt darüber,wieihre Inhalteim Editor angezeigt werden und wie sieim Front-End angezeigt werden.Das Kopierennureiniger relevanter Zeilen aus Ihrem Haupt-Stylesheetin Ihreneuetinymce.css kann sehr hilfreich sein:

 function custom_mce_css($wp) {
    return $wp .= ',' . get_bloginfo('stylesheet_directory') . '/css/tinymce.css';
}
add_filter( 'mce_css', 'custom_mce_css' );
 

Add custom styles to TinyMCE editor

Sometimes users and clients get confused about how their content is displayed in the editor versus how it is displayed on the front-end. Copying just a few relevant lines from your main stylesheet into your new tinymce.css can help a lot:

function custom_mce_css($wp) {
    return $wp .= ',' . get_bloginfo('stylesheet_directory') . '/css/tinymce.css';
}
add_filter( 'mce_css', 'custom_mce_css' );
