Benutzerdefinierte Abfrage mit orderby meta_value des benutzerdefinierten Felds

Sie können den Metaschlüsselfür den Parameter orderby mit der alten Methode definieren (dieichin WP 3.1.1getestet habe) ...

 query_posts(
    array(  'post_type' => 'services',
            'order'     => 'ASC',
            'meta_key' => 'some_key',
            'orderby'   => 'meta_value', //or 'meta_value_num'
            'meta_query' => array(
                                array('key' => 'order_in_archive',
                                      'value' => 'some_value'
                                )
                            )
    )
);
 

You can define the meta key for orderby parameter using the old method (I tested on WP 3.1.1)...

query_posts(
    array(  'post_type' => 'services',
            'order'     => 'ASC',
            'meta_key' => 'some_key',
            'orderby'   => 'meta_value', //or 'meta_value_num'
            'meta_query' => array(
                                array('key' => 'order_in_archive',
                                      'value' => 'some_value'
                                )
                            )
    )
);

Dieses Problem wirdim Allgemeinenin WordPress 4.2 mithilfebenannter Abfragenbehoben.z.B.

 $args = array(
  'post_type' => 'services',
  'orderby'   => 'order_clause',
  'meta_query' => array(
       'order_clause' => array(
            'key' => 'order_in_archive',
            'value' => 'some_value',
            'type' => 'NUMERIC' // unless the field is not a number
)));
 

Fürmich wollteichnacheinem numerischen Feldbestellen undmusste 'type' => 'NUMERIC'in der Meta-Abfrage.

This issue in general is cleared up in WordPress 4.2 by using named queries. e.g.

$args = array(
  'post_type' => 'services',
  'orderby'   => 'order_clause',
  'meta_query' => array(
       'order_clause' => array(
            'key' => 'order_in_archive',
            'value' => 'some_value',
            'type' => 'NUMERIC' // unless the field is not a number
)));

For me, I wanted to order by a numeric field and I had to use 'type' => 'NUMERIC' inside the meta query.

Der WP-Codexisttatsächlich verwirrend,wenn dieses Problembehoben wird.

Siebenötigen den Parametermeta_querynicht,um den orderby zu verwenden,sondern den Parametermeta_key,der,obwohler von WP Codex veraltetist,hiereingerichtet wurde: Wie verwenden Sie orderbymit meta_queryin Wordpress 3.1? ,die orderybynochbenötigtmeta_key.

so solltees sein

 query_posts( array(
  'post_type' => 'services',
  'order' => 'ASC',
  'orderby' => 'meta_value',
  'meta_key' => 'order_in_archive'
) )
 

The WP Codex is actually confusing when addressing this problem.

You do not actually need the meta_query param to use the orderby, instead it uses the meta_key param, which although by WP Codex is deprecated is has been established here: How do you use orderby with meta_query in Wordpress 3.1? that orderyby still needs the meta_key.

so it should be

query_posts( array(
  'post_type' => 'services',
  'order' => 'ASC',
  'orderby' => 'meta_value',
  'meta_key' => 'order_in_archive'
) )

Esisteinfach:

Hieristmein Code:

 query_posts(array( 
        'post_type' => 'directors',
        'posts_per_page' => -1,
        'order'    => 'ASC',
        'orderby'  => 'director_weight',
        'meta_key' => 'director_weight'
) );
 

Das Hauptdetailist:include meta_key,mein Code wurdenurbestellt,wenn meta_keyenthaltenist,und dasist alles:

Hierist der vollständige Codeeiner Liste von directors Bildern,dienach director_weight sortiert sind:

 <?php 
    query_posts(array( 
        'post_type' => 'directors',
        'posts_per_page' => -1,
        'order'    => 'ASC',
        'orderby'  => 'director_weight',
        'meta_key' => 'director_weight'
    ) );
    while (have_posts()) : the_post();
?>  
    <li <?php echo get_field('director_weight') ?>>
        <img src="<?php echo get_field('director_imagen') ?>">
    </li>
<?php
    endwhile;
    wp_reset_query();
?>
 

It´s easy:

Here is my code:

query_posts(array( 
        'post_type' => 'directors',
        'posts_per_page' => -1,
        'order'    => 'ASC',
        'orderby'  => 'director_weight',
        'meta_key' => 'director_weight'
) );

The main detail is: include meta_key, my code didn´t order unless meta_key is included, and that's all:

Here is the full code of a list of directors pictures order by director_weight:

<?php 
    query_posts(array( 
        'post_type' => 'directors',
        'posts_per_page' => -1,
        'order'    => 'ASC',
        'orderby'  => 'director_weight',
        'meta_key' => 'director_weight'
    ) );
    while (have_posts()) : the_post();
?>  
    <li <?php echo get_field('director_weight') ?>>
        <img src="<?php echo get_field('director_imagen') ?>">
    </li>
<?php
    endwhile;
    wp_reset_query();
?>

Verwenden Sienicht query_posts.

 $meta_query = new WP_Meta_Query( $meta_query_args );

$meta_query_args = array(
   'post_type' => 'services',
    'order'     => 'ASC',
    'meta_key' => 'your_key',
    'orderby'   => 'meta_value', //or 'meta_value_num'
    'meta_query' => array(
                    array('key' => 'order_in_archive',
                        'value' => 'some_value'
)));
 

Verwenden Sie die WP_Meta_Query-Parameter

Don't use query_posts.

$meta_query = new WP_Meta_Query( $meta_query_args );

$meta_query_args = array(
   'post_type' => 'services',
    'order'     => 'ASC',
    'meta_key' => 'your_key',
    'orderby'   => 'meta_value', //or 'meta_value_num'
    'meta_query' => array(
                    array('key' => 'order_in_archive',
                        'value' => 'some_value'
)));

Use the WP_Meta_Query parameters

Ichfand dasganzgut.

 <?php 
query_posts(
array(  'posts_per_page' => '-1',
        'post_type' => 'services',
        'order'     => 'DESC',
        'meta_key' => '_order',
        'orderby'   => 'meta_value_num', //or 'meta_value_num'
      )
);
 

I found this to work quite well.

<?php 
query_posts(
array(  'posts_per_page' => '-1',
        'post_type' => 'services',
        'order'     => 'DESC',
        'meta_key' => '_order',
        'orderby'   => 'meta_value_num', //or 'meta_value_num'
      )
);

Ich hatteeine Reihe vonbenutzerdefinierten Ereignisdaten,dieichnach absteigendem Datum sortierenmusste.Damein benutzerdefiniertes Ereignisdatumin meiner Tabelle wp_postmetagespeichert war und sichnormalerweise vom Datumpost_date oder dengeänderten Daten unterschied,funktionierte diesfürmich:

   $args = array(
    'post_type' => 'events', // my post type - yours can be 'posts'
    'post_status' => 'publish', // only get posts with this status
    'orderby' => 'meta_value', // orderby the meta_value of the following meta_key
    'meta_key' => 'my_custom_eventdate', // the custom meta_key name
    'order'=> 'DESC' // sort descending
  );

  $posts = new WP_Query($args);
 

Sie können dann $posts wiefolgt durchlaufen:

 foreach($posts->posts as $p){

    $post_id = $p->ID;
    // and so on ...

    // # example of how I retrieve my event date
    $event = get_post_meta($post_id, 'my_custom_eventdate', true);
}
 

I had a set of custom event dates I needed to sort by date descending. Since my custom event date was stored in my wp_postmeta table, and was typically different to the post_date or modified dates, this worked for me:

  $args = array(
    'post_type' => 'events', // my post type - yours can be 'posts'
    'post_status' => 'publish', // only get posts with this status
    'orderby' => 'meta_value', // orderby the meta_value of the following meta_key
    'meta_key' => 'my_custom_eventdate', // the custom meta_key name
    'order'=> 'DESC' // sort descending
  );

  $posts = new WP_Query($args);

You can then loop through $posts like so:

foreach($posts->posts as $p){

    $post_id = $p->ID;
    // and so on ...

    // # example of how I retrieve my event date
    $event = get_post_meta($post_id, 'my_custom_eventdate', true);
}

Diese Arbeitfürmich,

     $args = array(
        'post_type' => 'services',
        'order' => 'ASC',
        'orderby'   => 'order_clause',   
        'meta_query' => array(
        'order_clause' => array(
        'key' => 'order_in_archive'
    )));
 

Wirdnurbenötigt,um den Schlüsselfür die order_clause

This work for me,

    $args = array(
        'post_type' => 'services',
        'order' => 'ASC',
        'orderby'   => 'order_clause',   
        'meta_query' => array(
        'order_clause' => array(
        'key' => 'order_in_archive'
    )));

Only needed to provide the key for the order_clause
