Ich versuche,ein Formular zuerstellen,mit dem Benutzerihre Informationenim Frontend aktualisieren können. Ichfangegerade an,PHP zu lernen (ich kenne C # sehrgut). Wennich diesen Code verwende,umein Formular aufeiner WordPress-Seite zuerstellen,wieerhalteich die Informationen vom Benutzer,wenner auf die Schaltfläche "Aktualisieren" klickt und dann die Datenbank aktualisiert?

 function Insert_AccountTable_1()
{
    $current_user = wp_get_current_user();

    if ($current_user->ID != 0)
    {
        return <<<HTML
            <form class="AlumniForm" method="post">
            <h3>Name</h3>
            <br>
            <table>
                <tbody>

add_shortcode('InsertAccountTableI', 'Insert_AccountTable_1');

I am trying to create a form that will allow users to update their information on the front end. I am just starting to learn PHP (I know C# very well). If I use this code to create a form on a WordPress page, how do I get the information from the user when they press the 'Update' button and then update the database?

function Insert_AccountTable_1()
{
    $current_user = wp_get_current_user();

    if ($current_user->ID != 0)
    {
        return <<<HTML
            <form class="AlumniForm" method="post">
            <h3>Name</h3>
            <br>
            <table>
                <tbody>
                    <tr>
                        <th><label for="Username">Username</label></th>
                        <td><span>$current_user->user_login</span></td>
                        <td><span class="description">Usernames cannot be changed.</span></td>
                    </tr>
                    <tr>
                        <th><label for="current_user_firstname">First Name</label></th>
                        <td><input id="current_user_firstname" type="text" name="current_user_firstname" value="$current_user->user_firstname"/></td>

- Hallo @William,deine Frageistetwas weitgefasst,da sienicht wirklich WordPress-spezifischist,sondern auch allgemeine PHP-Kenntnisse.Bitte überprüfen Sie zuerst die HTML- und PHP-Formularerstellung. Anschließend können Sie die Funktion `wp_update_user ($ user)` verwenden,um dies zuerreichen.
  
  Hi @William, your question is a bit broad as it is not really WordPress specific, but also general PHP knowledge. Please check the HTML & PHP formbuilding first - afterwards you can use the `wp_update_user($user)` function to achieve that.

Verwenden Sie wp-admin/admin-post.php als Handlerfür Formularaktionen undbinden Sie Ihrebenutzerdefinierte Funktion als Rückruf daran.

Eineinfaches Beispielfür E-Mail-Updates. Wir werden hiereinen Shortcodemit dem Namen [Benutzerformular] verwenden,aber Sie können aucheine Vorlage verwenden.

  add_shortcode ('userform','wpse_75723_userform');
add_action ('admin_post_update_user_email','wpse_75723_update');

/**
 * Erstellen Sie das Formular.
 */
Funktion wpse_75723_userform ()
{
    $ here=esc_url (home_url ($ _SERVER ['REQUEST_URI']));

 if (!is_user_logged_in ())
        return 'Siemüssen & lt; a href="'. wp_login_url ($ here). '" > Login & lt;/a > um diese Seite zubenutzen. ';

    $ action=admin_url ('admin-post.php');
    $ user_id=get_current_user_id ();

    return "& lt;formmethod='post' action='$ action' >
    & lt;inputtype='hidden'name='action' value='update_user_email' >
    & lt;inputtype='hidden'name='redirect' value='$ here' >
    & lt;inputtype='hidden'name='user_id' value='$ user_id' >
    & lt; Eingabetyp='E-Mail' Name='E-Mail' Größe='15' >
    & lt;inputtype='submit' >
    & lt;/form > ";
}}

/**
 * Benutzer-E-Mail aktualisieren
 */
Funktion wpse_75723_update ()
{
 if (!isset ($ _POST ['user_id']))
        sterben ('noid');

    $ user_id=absint ($ _POST ['user_id']);

 if (! current_user_can ('edit_user',$ user_id))
        sterben ('nichterlaubt');

 if (!isset ($ _POST ['email']))
        sterben ('keine E-Mail');

 if (!is_email ($ _POST ['email']))
        sterben ('ungültige E-Mail');

    $ user=get_userdata ($ user_id);

 if (leer ($ user- > user_login))
        sterben ('Benutzer verweigert');

 global $ wpdb;

    $ wpdb- > query (
        $ wpdb- > vorbereiten (
            "UPDATE {$ wpdb- > Benutzer} SET user_email=% s WHERE user_login=% s",
            $ _POST ['email'],
            $ user- > user_login
        )
    );

    $ location=isset ($ _POST ['redirect'])
 ? urldecode ($ _POST ['redirect'])
        : home_url ('/');

    wp_redirect ($ location,303);
    Ausfahrt;
}}

Einfügen…

  [Benutzerformular]

…in eine Seite wirdeine Grundformerzeugt:

Der Benutzer kann hier seine E-Mail-Adresse ändern.

Um zu verstehen,welche Variablen verfügbar sind und wo siegespeichert sind,sehen Sie sich diese Dateien an:

wp-admin/user-edit.php
wp-admin/includes/user.php und
wp-includes/user.php

Die Tabellen Benutzer und user_meta sindebenfallseinen Blick wert,wenn Sieeinfache SQL-Abfragen sendenmöchten.


                                                                        Use wp-admin/admin-post.php as form action handler, and bind your custom function as callback to that.

A simple example for email updates. We will use a shortcode named [userform] here, but you can use a template too.

add_shortcode( 'userform', 'wpse_75723_userform' );
add_action( 'admin_post_update_user_email', 'wpse_75723_update' );

/**
 * Create the form.
 */
function wpse_75723_userform()
{
    $here = esc_url( home_url( $_SERVER['REQUEST_URI'] ) );

    if ( ! is_user_logged_in() )
        return  'You have to <a href="' . wp_login_url( $here ) . '">log in</a> to use this page.';

    $action  = admin_url( 'admin-post.php');
    $user_id = get_current_user_id();

    return "<form method='post' action='$action'>
    <input type='hidden' name='action' value='update_user_email'>
    <input type='hidden' name='redirect' value='$here'>
    <input type='hidden' name='user_id' value='$user_id'>
    <input type='email' name='email' size='15'>
    <input type='submit'>
    </form>";
}

/**
 * Update user email
 */
function wpse_75723_update()
{
    if ( ! isset ( $_POST['user_id'] ) )
        die( 'no id' );

    $user_id = absint( $_POST['user_id'] );

    if ( ! current_user_can( 'edit_user', $user_id ) )
        die( 'not allowed' );

    if ( ! isset ( $_POST['email'] ) )
        die( 'no email' );

    if ( ! is_email( $_POST['email'] ) )
        die( 'invalid email' );

    $user = get_userdata( $user_id );

    if ( empty ( $user->user_login ) )
        die( 'user denied' );

    global $wpdb;

    $wpdb->query(
        $wpdb->prepare(
            "UPDATE {$wpdb->users} SET user_email = %s WHERE user_login = %s",
            $_POST['email'],
            $user->user_login
        )
    );

    $location = isset ( $_POST['redirect'] )
        ? urldecode( $_POST['redirect'] )
        : home_url( '/' );

    wp_redirect( $location, 303 );
    exit;
}


Inserting …

[userform]


… into a page will produce a basic form:


  


The user can change her/his email address here.

To understand what variables are available and where they are stored look at these files:


wp-admin/user-edit.php
wp-admin/includes/user.php and
wp-includes/user.php


The tables users and user_meta are worth a look too if you want to send plain SQL queries.
