你的问题很复杂。如果不进入你的系统，很难解决它。对于您的情况，我更愿意运行数据库查询，但它对我来说太复杂了。顺便说一下，我试着写一个简单的PHP 脚本-

function the_dramatist_get_post_by_title( $page_title, $post_type =\'post\' ) {
    global $wpdb;
    $post = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_title = %s AND post_type= %s", $page_title, $post_type));
    if ( $post )
        return $post;

    return null;
}

function the_dramatist_bulk_copy_c_fields() {
    $c_posts = wp_list_pluck( get_posts(array(
        \'post_type\'=>\'catalog\',
        \'posts_per_page\' => -1
    )), \'ID\' );

    foreach($c_posts as $c){
        $title = get_the_title( $c );
        $s_id = the_dramatist_get_post_by_title( $title, \'services\');
        $meta_value = get_post_meta( $s_id, \'price\', true );
        add_post_meta( $c, \'price\', $meta_value );
    }
    return true;
}

add_action(\'init\', \'the_dramatist_bulk_copy_c_fields\');

希望这有帮助。
