wp_list_pages( $args ) 呼叫get_pages( $args ). 您可以筛选get_pages() 过滤器打开时的输出get_pages.

假设你打电话wp_list_pages() 像这样：

wp_list_pages(
    array(
        \'please_filter_me\' => TRUE
    )
);

add_filter( \'get_pages\', function( $pages, $args ) {
    // not our query
    if ( empty ( $args[\'please_filter_me\'] ) )
        return $pages;

    $out = $top = array();

    foreach ( $pages as $page )
    {
        if ( get_post_meta( $page->ID, \'my_key\', TRUE ) )
            $top[] = $page;
        else
            $out[] = $page;
    }

    return $top + $out;
}, 10, 2 );
