您可以在上筛选段塞创建wp_unique_post_slug 钩

//Register the filter
add_filter(\'wp_unique_post_slug\',\'prefix_the_slug\',10,6);

function prefix_the_slug($slug, $post_ID, $post_status, $post_type, $post_parent, $original_slug){
    //Get value from the custom field
    $prefix = get_post_meta($post_ID,\'cw_event_start_date\',true);

    //Only prefix certain post type and if prefix field existed
    if($post_type===\'post\' && $prefix && !empty($prefix)){

        //Prefix only if it is not already prefixed
        preg_match (\'/^\\d\\d\\d\\d\\d\\d/\', $slug, $matches, PREG_OFFSET_CAPTURE);
        if(empty($matches)){
            return $prefix.\'-\'.$slug;                       
        }
    }
    return $slug;
