Wordpress - 自定义帖子类型和自定义永久链接结构错误

Question

I have 3 custom post types setup and I have created a custom permalink structure for each. The problem I am having is that the third custom post type I have setup with the custom permalink, is being used for the previous 2.

Example:

• Classified
• Employment
• Sponsorship

The above are the post types and I have the custom permalink structure set to (for each): /post_type/post_id/

Now, The above order are the order they are set in and sponsorship takes over all of them. So for instance:

/classified/100/
/employment/101/
/sponsorship/102/

The above all use the permalink:

/sponsorship/100/
/sponsorship/101/
/sponsorship/102/

What am I doing wrong to get this error happening? Is it a permalink structure error? below is my code I am using to create the custom permalink structures for each. The only difference is that %c_id% is changed to %e_id% and %s_id% for classifieds, employment and sponsorship. And also any reference to 'classifieds' is changed to employment and sponsorship respectively.

add_action('init', 'classifieds_rewrite');
function classifieds_rewrite() {
    global $wp_rewrite;

    $queryarg = 'post_type=classifieds&p=';
    $wp_rewrite->add_rewrite_tag('%c_id%', '([^/]+)', $queryarg);
    $wp_rewrite->add_permastruct('classifieds', '/classifieds/%c_id%/', false);
}

add_filter('post_type_link', 'classifieds_permalink', 1, 3);
function classifieds_permalink($post_link, $id = 0) {
    global $wp_rewrite;
    $post = &get_post($id);
    if ( is_wp_error( $post ) )
        return $post;
    $newlink = $wp_rewrite->get_extra_permastruct('classifieds');
    $newlink = str_replace("%c_id%", $post->ID, $newlink);
    $newlink = home_url(user_trailingslashit($newlink));
    return $newlink;
}

Thanks for the help! :)

Answer 1

If I understand correctly, you registered 3 different post types and you are trying to rewrite each post type so their slug precedes the post id. To start with just the slug of each post type, it doesn't seem like you are issuing the rewrite when you register each post type, is this correct? If not, you can take care of this part by adding the following with the other arguments when registering each post type.

'rewrite' => array( 'slug' => 'classified', 'with_front' => true )
