我为一个主题创建了一个函数，该函数限制了画廊中显示的图像数量。这在Gallery post格式中。但是，我想限制所有页面上的图库图像，但单个帖子除外。

到目前为止，我的代码如下（用特定于所讨论的属性的部分进行了缩短）：

function the_mx_limited_gallery( $attr ) {
    $post = get_post();
    $attachment_ids = the_mx_get_limited_gallery_ids();
    $link_image_to = the_mx_medialink_switcher(); // Customizer controls
    if( get_post_format() == \'gallery\' ) { // opens gallery post format check
    ...
    // setup shortcode attributes
    $atts = shortcode_atts( array(
        \'order\' => \'ASC\',
        \'orderby\' => \'menu_order ID\',
        \'id\' => $post ? $post->ID : 0,
        \'itemtag\' => \'figure\',
        \'icontag\' => \'div\',
        \'captiontag\' => \'figcaption\',
        \'columns\' => 3,
        \'include\' => $attachment_ids,
        \'size\' => \'gallery-thumb\',
        \'link\' => $link_image_to,

    ), $atts );

    $id = intval( $atts[\'id\'] );

    if ( ! empty( $atts[\'include\'] ) ) {
        $_attachments = get_posts( array( 
            \'include\' => $atts[\'include\'], 
            \'post_status\' => \'inherit\', 
            \'post_type\' => \'attachment\', 
            \'post_mime_type\' => \'image\', 
            \'order\' => $atts[\'order\'], 
            \'orderby\' => $atts[\'orderby\'],
        ) );

        $attachments = array();
        foreach ( $_attachments as $key => $val ) {
            $attachments[$val->ID] = $_attachments[$key];
        }
    } elseif ( ! empty( $atts[\'exclude\'] ) ) {
        $attachments = get_children( array( 
            \'post_parent\' => $id, 
            \'exclude\' => $atts[\'exclude\'], 
            \'post_status\' => \'inherit\', 
            \'post_type\' => \'attachment\', 
            \'post_mime_type\' => \'image\', 
            \'order\' => $atts[\'order\'], 
            \'orderby\' => $atts[\'orderby\'] 
        ) );
    } else {
        $attachments = get_children( array( 
            \'post_parent\' => $id, 
            \'post_status\' => \'inherit\', 
            \'post_type\' => \'attachment\', 
            \'post_mime_type\' => \'image\', 
            \'order\' => $atts[\'order\'], 
            \'orderby\' => $atts[\'orderby\'] 
        ) );
    }

    ...

}

检索gallery ID（The\\u mx\\u get\\u limited\\u gallery\\u ID）的代码如下：

// Function for limiting Gallery ID length (in the Gallery post format).
// see http://www.webgurus.biz/how-to-limit-wordpress-gallery-thumbnails-in-the-loop/
function the_mx_get_limited_gallery_ids() {
    global $wpdb, $post;
        $ids = \'\';
        $counter = 0;
        $number_of_posts = 6;
        $args = array(
            \'post_type\' => \'attachment\',
            \'numberposts\' => 6,
            \'orderby\' => \'menu_order\',
            \'order\' => \'ASC\',
            \'post_status\' => null,
            \'post_parent\' => $post->ID,
        );
        $attachments = get_posts($args);
        if($attachments) {
            foreach ($attachments as $attachment) {

                if($counter != 0) {
                    $ids .= \',\'.$attachment->ID;
                } else {
                    $ids .= $attachment->ID;
                }
                $counter++;

            }
        }
        return $ids;
}

为了在前端显示，我尝试只使用筛选shortcode_atts_gallery 并显示为do_shortcode, 但在我的测试环境中，这会干扰Jetpack的库添加。我想让我的画廊和Jetpack画廊一起展出。

任何帮助都将不胜感激。

function the_mx_limited_gallery( $attr ) {
    $post = get_post();
    $attachment_ids = the_mx_get_limited_gallery_ids();
    $link_image_to = the_mx_medialink_switcher(); // Customizer controls
    $mx_colcount = the_mx_gal_colcount_switcher(); // Customizer controls
    if( get_post_format() == \'gallery\' ) { // opens gallery post format check

        if( !is_single() ) { // opens non single page if statement
        // setup shortcode attributes
        $atts = shortcode_atts( array(
        ...

        } // closes non single page if statement

    } // closes gallery post format
}
add_filter( \'post_gallery\', \'the_mx_limited_gallery\', 10, 1 );
