Code Snippet to Disable WordPress Comments on Specific Post Types

Disable Comments for Specific Post Types

Custom Code Solution

Add this code to your theme's functions.php file or in a site-specific plugin:

This code removes comment support and hides comment UI elements for specified post types:

function disable_comments_for_post_types() {
    // Add your post types to this array
    $post_types = array('page', 'product', 'portfolio');
    
    // Remove comment support
    foreach ($post_types as $post_type) {
        remove_post_type_support($post_type, 'comments');
        remove_post_type_support($post_type, 'trackbacks');
    }
    
    // Hide existing comments
    if (is_post_type_archive($post_types)) {
        add_filter('comments_open', '__return_false');
        add_filter('pings_open', '__return_false');
    }
}
add_action('init', 'disable_comments_for_post_types');

To also remove comment-related UI elements from the admin area:

function remove_comment_support_admin() {
    // Add your post types to this array
    $post_types = array('page', 'product', 'portfolio');
    
    // Remove comment metaboxes
    foreach ($post_types as $post_type) {
        remove_meta_box('commentstatusdiv', $post_type, 'normal');
        remove_meta_box('commentsdiv', $post_type, 'normal');
    }
}
add_action('admin_init', 'remove_comment_support_admin');

Notes

• Replace the post types in the $post_types array with your desired post types
• The code works for both built-in and custom post types
• For custom post types, you can alternatively set 'supports' => array() without 'comments' when registering the post type
