Is there ANY way to remove comments function and section totally?

Question

I don't want any comment querys to run. I don't wont anything about comments to be shown in wordpress admin area.

Is this possible in any way?

EDIT: Remove all links to the comments from admin bar, and all of the backend section.

Answer 1

There's an out-of-the-box solution that does just that. It's a plugin from Frank Bültge

Docs: http://wpengineer.com/2230/removing-comments-absolutely-wordpress/

Plug-in download: https://github.com/bueltge/Remove-Comments-Absolutely

Just install, and thats it. no config.

It works fine with WP 3.5

Answer 2

Here is a list of all of the above answers and a removal of the admin bar link. Just add it to your themes function file or make it a plugin. I will mark this as a community wiki as everyone's answer is right just no one added it all together.

<?php
// Removes from admin menu
add_action( 'admin_menu', 'my_remove_admin_menus' );
function my_remove_admin_menus() {
    remove_menu_page( 'edit-comments.php' );
}
// Removes from post and pages
add_action('init', 'remove_comment_support', 100);

function remove_comment_support() {
    remove_post_type_support( 'post', 'comments' );
    remove_post_type_support( 'page', 'comments' );
}
// Removes from admin bar
function mytheme_admin_bar_render() {
    global $wp_admin_bar;
    $wp_admin_bar->remove_menu('comments');
}
add_action( 'wp_before_admin_bar_render', 'mytheme_admin_bar_render' );
?>

Answer 3

This should remove support for comments on your site:

add_action('admin_menu', 'remove_comment_support');

function remove_comment_support() {
    remove_post_type_support( 'post', 'comments' );
    remove_post_type_support( 'page', 'comments' );
}

I don't know if it will hide every mention of comments in the admin section, though. The "Right Now" box on the dashboard is mostly hard-coded, so you'd have to hide that box or do some hackery to filter out the line about "Comments". But it should remove the "comments" text everywhere else that I can think of.

Answer 4

This will not remove it from your markup per se, but you can easily hide the WP 3.1 admin bar link (both visually and from screen-readers) by adding the following line to your theme's CSS:

li#wp-admin-bar-comments { display: none; visibility: hidden; }

Answer 5

To remove the Comments menu:

add_action( 'admin_init', 'my_remove_admin_menus' );
function my_remove_admin_menus() {
    remove_menu_page( 'edit-comments.php' );
}
