How can I add the string "p" in front of every post url in this cutom post type?
I added it in my code, wordpress is generating the link but when I click, it returns 404.
What do I need to do?

<?php

/**

 * news ====================================================

 */

add_action('init', 'my_custom_news');

function my_custom_news()

{

  $labels = array(

    'name' => _x('新着情報', 'post type general name'),

    'singular_name' => _x('news', 'post type singular name'),

    'add_new' => _x('新しく新着情報を書く', 'news'),

    'add_new_item' => __('新着情報記事を書く'),

    'edit_item' => __('新着情報記事を編集'),

My Answer:
to the permalink in WordPress using PHP?

You can add a string to the permalink in WordPress by using the `post_link` filter hook. Here's an example code snippet to add a string to the permalink:

php
function custom_permalink($permalink, $post) {
// Add your custom string here
$custom_string = 'custom-string';

// Append the custom string to the permalink
$permalink = $permalink . $custom_string;

return $permalink;
}

add_filter('post_link', 'custom_permalink', 10, 2);


You can add this code to your theme's `functions.php` file or in a custom plugin. This code will append the custom string to the end of the permalink for all posts in your WordPress site.
