Shut off HTML on comments

Define “shut off”. Do you want html to be stripped out entirely? Because that won’t exactly work with <3 things, it would strip everything after the < mark.

If you want html to be displayed as actual code, like if somebody types <b> then that actually shows up, you could add this to your theme’s functions.php file:

add_filter('pre_comment_content','wp_specialchars');

That will convert all <‘s into &lt;’s and so forth, making it not html anymore.

Oh that is exactly what I mean! Thank you very much.

Me and my visitors wants to do <3 hearts

That tells me you want the “smiley” thing. Search.

Noo i dont wanna do smileys! I want to do as it shows! Like when you type <b> is shall be like that. I dont want them to do any html at all, just plain text.

And I do not have an functions.php in my theme, what do i do then?

Create one. Make a text file. Put this in it:

<?php
add_filter('pre_comment_content','wp_specialchars');
?>

Make sure that it has NO blank lines or spaces at the top (before the <?php) or at the bottom (after the ?>). Everything in the file must be inside the ? lines.

Then rename the file to functions.php and upload it to your theme directory.
