重写URL-将自定义变量作为目录路径插入

我正试图在WordPress中用我自己的自定义url为Divi主题“project”重写permalink结构

我已经将“Divi slug”从“project”更改为“prodotti”，因此当前，URL如下所示：

http://www.example.com/prodotti/%postname%/

使用我的自定义功能

function custom_post_name() {
    return array(
        \'feeds\' => true,
        \'slug\' => \'prodotti\',
        \'with_front\' => false,
    );
}
add_filter(\'et_project_posttype_rewrite_args\', \'custom_post_name\');

我想add to these urls a variable, that reside for each post in post_metadata, 为了构建url，如：

http://www.example.com/prodotti/<mypostoptionvalue>/%postname%/

例如：

http://www.example.com/prodotti/AEX1102/%postname%/
http://www.example.com/prodotti/AEX1103/%postname%/
http://www.example.com/prodotti/AEX1104/%postname%/

有没有办法实现这种行为？

我做了很多测试，{$permastruct}_rewrite_rules, page_rewrite_rules, post_rewrite_rules 更多信息，从以下方面开始：https://codex.wordpress.org/Class_Reference/WP_Rewrite 没有结果。

add_action(\'init\', \'my_rewrite\'); function my_rewrite() { global $wp_rewrite; // Your desired structure $permalink_structure = \'/prodotti/%my_custom_variable%/%postname%/\' // add the custom variable to wp_rewrite tags $wp_rewrite->add_rewrite_tag("%my_custom_variable%", \'([^/]+)\', "my_custom_variable="); // Here you need to know the name of the custom post type you want the permalink structure to be used on $wp_rewrite->add_permastruct(\'custom_post_type_name\', $permalink_structure, false); }

add_filter(\'post_type_link\', \'intercept_permalink\', 10, 3); function intercept_permalink ($permalink, $post, $leavename) { //check if current permalink has our custom variable if ( strpos($permalink, \'%my_custom_variable%\') !== false ) { //get this post\'s meta data with $post->ID $my_str = get_post_meta($post->ID, \'meta_key\'); //maybe check if post meta data is legit and perhaps have some kind of fallback if it\'s empty or something //Then we just replace the custom variable string with our new string $permalink = str_replace(\'%my_custom_variable%\', strtolower($my_str), $permalink); } return $permalink; }
