Comment obtenir une liste de toutes les tailles de vignettes possibles définies dans un thème

Je l'aitrouvéici .La réponseest:

 global $_wp_additional_image_sizes; 
print '<pre>'; 
print_r( $_wp_additional_image_sizes ); 
print '</pre>';
 

Found it here. The answer is:

global $_wp_additional_image_sizes; 
print '<pre>'; 
print_r( $_wp_additional_image_sizes ); 
print '</pre>';

Lenoyau WordPress n'apas deméthodenative pour obtenir destailles d'imageintermédiaires (c.-à-d. largeuret hauteur),mais la fonction d'assistance suivante obtiendratailles d'imageenregistrées avec leurs dimensions:

 /**
 * Get all the registered image sizes along with their dimensions
 *
 * @global array $_wp_additional_image_sizes
 *
 * @link http://core.trac.wordpress.org/ticket/18947 Reference ticket
 *
 * @return array $image_sizes The image sizes
 */
function _get_all_image_sizes() {
    global $_wp_additional_image_sizes;

    $default_image_sizes = get_intermediate_image_sizes();

    foreach ( $default_image_sizes as $size ) {
        $image_sizes[ $size ][ 'width' ] = intval( get_option( "{$size}_size_w" ) );
        $image_sizes[ $size ][ 'height' ] = intval( get_option( "{$size}_size_h" ) );
        $image_sizes[ $size ][ 'crop' ] = get_option( "{$size}_crop" ) ? get_option( "{$size}_crop" ) : false;
    }

    if ( isset( $_wp_additional_image_sizes ) && count( $_wp_additional_image_sizes ) ) {
        $image_sizes = array_merge( $image_sizes, $_wp_additional_image_sizes );
    }

    return $image_sizes;
}
 

Quiproduira des résultats similaires à:

 Array
(
    [thumbnail] => Array
        (
            [width] => 150
            [height] => 150
            [crop] => 1
        )

    [medium] => Array
        (
            [width] => 300
            [height] => 300
            [crop] => 
        )

    [medium_large] => Array
        (
            [width] => 768
            [height] => 0
            [crop] => 
        )

    [large] => Array
        (
            [width] => 1024
            [height] => 1024
            [crop] => 
        )

)
 

WordPress core doesn't have a native method for getting intermediate image sizes (i.e. width and height), but the following helper function will get all registered image sizes along with their dimensions:

/**
 * Get all the registered image sizes along with their dimensions
 *
 * @global array $_wp_additional_image_sizes
 *
 * @link http://core.trac.wordpress.org/ticket/18947 Reference ticket
 *
 * @return array $image_sizes The image sizes
 */
function _get_all_image_sizes() {
    global $_wp_additional_image_sizes;

    $default_image_sizes = get_intermediate_image_sizes();

    foreach ( $default_image_sizes as $size ) {
        $image_sizes[ $size ][ 'width' ] = intval( get_option( "{$size}_size_w" ) );
        $image_sizes[ $size ][ 'height' ] = intval( get_option( "{$size}_size_h" ) );
        $image_sizes[ $size ][ 'crop' ] = get_option( "{$size}_crop" ) ? get_option( "{$size}_crop" ) : false;
    }

    if ( isset( $_wp_additional_image_sizes ) && count( $_wp_additional_image_sizes ) ) {
        $image_sizes = array_merge( $image_sizes, $_wp_additional_image_sizes );
    }

    return $image_sizes;
}

Which will output results similar to:

Array
(
    [thumbnail] => Array
        (
            [width] => 150
            [height] => 150
            [crop] => 1
        )

    [medium] => Array
        (
            [width] => 300
            [height] => 300
            [crop] => 
        )

    [medium_large] => Array
        (
            [width] => 768
            [height] => 0
            [crop] => 
        )

    [large] => Array
        (
            [width] => 1024
            [height] => 1024
            [crop] => 
        )

)

Si vousn'avezbesoin que desnoms detoutes lestailles d'image,vouspouvez utiliser get_intermediate_image_sizes :

 <pre>
<?php print_r(get_intermediate_image_sizes()); ?>
</pre>
 

If you only need the names of all image sizes, you can use get_intermediate_image_sizes:

<pre>
<?php print_r(get_intermediate_image_sizes()); ?>
</pre>

Si l'autre réponsene fonctionnepas,utilisez ce codepour qu'il s'exécute après l'initialisation de WordPress.

 add_action('init', 'get_all_image_sizes');

function get_all_image_sizes(){
    global $_wp_additional_image_sizes; 
    print '<pre>'; 
    print_r( $_wp_additional_image_sizes ); 
    print '</pre>';
}
 

If the other answer did not work, use this code, so it will run after WordPress is initialized.

add_action('init', 'get_all_image_sizes');

function get_all_image_sizes(){
    global $_wp_additional_image_sizes; 
    print '<pre>'; 
    print_r( $_wp_additional_image_sizes ); 
    print '</pre>';
}

Depuis WP 5.3,il suffit d'utiliser cettefonction:

 wp_get_registered_image_subsizes();
 

Since WP 5.3 it is enough to use this function:

wp_get_registered_image_subsizes();
