Disabling HTML on Comments

Question

I've been researching for the past few hours, trying to find a way to disable HTML in WordPress comments. So far this one consistently appeared on top of Google search results numerous times:

// This will occur when the comment is posted function plc_comment_post( $incoming_comment ) { // convert everything in a comment to display literally $incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']); // the one exception is single quotes, which cannot be #039; because WordPress marks it as spam $incoming_comment['comment_content'] = str_replace( "'", '&apos;', $incoming_comment['comment_content'] ); return( $incoming_comment ); } // This will occur before a comment is displayed function plc_comment_display( $comment_to_display ) { // Put the single quotes back in $comment_to_display = str_replace( '&apos;', "'", $comment_to_display ); return $comment_to_display;

This code did not work with the latest version of WordPress. I also found many more codes that again, did not work. So how would one go about disabling HTML in WordPress 3.6 (the latest version) comments?

@Cole"Cole9"Johnson not sure but i found a solution to this problem :) — Dyck

This removed the ability for users to post HTML (but not links for some strange reason) within comments:

add_filter( 'pre_comment_content', 'wp_specialchars' );

This removed the ability for users to post links within comments:

remove_filter('comment_text', 'make_clickable', 9);

add_filter( 'pre_comment_content', 'wp_filter_nohtml_kses' ); has got links covered too.

And you add add_filter('get_comment_author_link', array('Comments_Cleaner', 'RemoveHTML')); and no spammer will spam you with links :)

This answer disables HTML by replacing HTML code with plaintext. Whereas the answer by Jothi disables HTML by removing the HTML code (e.g. <b>hello</b> becomes hello).

To disable HTML tags in comments, put the following code into your theme's functions.php:

add_filter('comment_text', 'wp_filter_nohtml_kses'); add_filter('comment_text_rss', 'wp_filter_nohtml_kses'); add_filter('comment_excerpt', 'wp_filter_nohtml_kses');

This is not what I want to do, I just wanted to disable them from COMMENTS not my whole website in general.
