Add a string to ter permalink in wordpress - php

Question

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'),
'new_item' => __('新しい新着情報記事'),
'view_item' => __('新着情報記事を見る'),
'search_staff' => __('新着情報記事を探す'),
'not_found' => __('新着情報記事はありません'),
'not_found_in_trash' => __('ゴミ箱に新着情報記事はありません'),
'parent_item_colon' => ''
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,

'rewrite' => array(
"slug" => "news",

'menu_position' => 5,
'supports' => array('title','excerpt','editor','revisions'),
'has_archive' => true
);
register_post_type('news',$args);
}
/** ---- 新着情報タクソノミー追加 ---- **/
add_action ('init','create_newscat_taxonomy','0');
function create_newscat_taxonomy () {
$taxonomylabels = array(
'name' => _x('新着情報カテゴリー','post type general name'),
'singular_name' => _x('新着情報カテゴリー','post type singular name'),
'search_items' => __('新着情報カテゴリー'),

);
register_taxonomy('newscat','news',$args);
}
// Rewrite Custom Taxonomy to share base slug with Custom Post Type
function rewrite_news_category() {
$news_category_args = get_taxonomy( 'newscat' ); // returns an object
$news_category_args->show_admin_news = true;
$news_category_args->rewrite['slug'] = 'news';
$news_category_args->rewrite['with_front'] = false;
register_taxonomy( 'newscat', 'news', (array) $news_category_args );
}
add_action( 'init', 'rewrite_news_category', 11 );
function news_rewrites_init($post_link, $post = 0){
add_rewrite_rule('news\/([0-9]+)?(page\/)?([0-9]+)?\/?$', 'index.php?paged=$matches[3]&post_type=news&p=$matches[1]', 'top');
add_rewrite_rule('news\/([A-Za-z0-9-_]+)\/?(page\/)?([0-9]+)?\/?$', 'index.php?paged=$matches[3]&newscat=$matches[1]', 'top');
}
add_action('init', 'news_rewrites_init');
function cms_links1($post_link, $post) {
if($post->post_type === 'news') {
return home_url('news/p' . $post->ID . '/');
} else {
return $post_link;
}
}
add_filter('post_type_link', 'cms_links1', 1, 3);

Answer 1

By the adding string "p" in the "rewrite" argument of your custom post type:
'rewrite' => array(
"slug" => "news/p",
"with_front" => false
)
Change the links:
function mycustomname_links($post_link, $post = 0) {
if($post->post_type === 'news') {
return home_url('news/p' . $post->ID . '/');
}
else{
return $post_link;
}
}
add_filter('post_type_link', 'mycustomname_links', 1, 3);
Add the correct rewrites rules:
function mycustomname_rewrites_init(){
add_rewrite_rule('news/p([0-9]+)?$', 'index.php?post_type=news&p=$matches[1]', 'top');
}
add_action('init', 'mycustomname_rewrites_init');
After this you need to flush the permalink:
In your WordPress backend go to settings-> permalinks-> save changes
Now your URL looks like this:
localhost/demo/news/p83(post id)
