Sometimes, WordPress is used for websites that are not blogs. And sometimes, those websites don’t want to hear back from people on the internet, because; let’s face it, people on the internet can suck. So if you want to make sure those sucky people don’t comment on your site, don’t try and delete the wp_comments table from the WordPress database like this guy thought he could do. That’s just going to cause problems. Instead, try this code.
// Disable support for comments and trackbacks in post types
function df_disable_comments_post_types_support() {
$post_types = get_post_types();
foreach ($post_types as $post_type) {
if(post_type_supports($post_type, ‘comments’)) {
remove_post_type_support($post_type, ‘comments’);
remove_post_type_support($post_type, ‘trackbacks’);
}
}
}
add_action(‘admin_init’, ‘df_disable_comments_post_types_support’);
// Close comments on the front-end
function df_disable_comments_status() {
return false;
}
add_filter(‘comments_open’, ‘df_disable_comments_status’, 20, 2);
add_filter(‘pings_open’, ‘df_disable_comments_status’, 20, 2);
// Hide existing comments
function df_disable_comments_hide_existing_comments($comments) {
$comments = array();
return $comments;
}
add_filter(‘comments_array’, ‘df_disable_comments_hide_existing_comments’, 10, 2);
// Remove comments page in menu
function df_disable_comments_admin_menu() {
remove_menu_page(‘edit-comments.php’);
}
add_action(‘admin_menu’, ‘df_disable_comments_admin_menu’);
// Redirect any user trying to access comments page
function df_disable_comments_admin_menu_redirect() {
global $pagenow;
if ($pagenow === ‘edit-comments.php’) {
wp_redirect(admin_url()); exit;
}
}
add_action(‘admin_init’, ‘df_disable_comments_admin_menu_redirect’);
// Remove comments metabox from dashboard
function df_disable_comments_dashboard() {
remove_meta_box(‘dashboard_recent_comments’, ‘dashboard’, ‘normal’);
}
add_action(‘admin_init’, ‘df_disable_comments_dashboard’);
// Remove comments links from admin bar
function df_disable_comments_admin_bar() {
if (is_admin_bar_showing()) {
remove_action(‘admin_bar_menu’, ‘wp_admin_bar_comments_menu’, 60);
}
}
add_action(‘init’, ‘df_disable_comments_admin_bar’);
Just take the code snippets you want from this, and drop them into the theme’s functions.php file to disable comments site wide.
