nested paragraphs in comment post errors

[tnbnicer]

Line 30 in ‘wordpress/wp-comments-post.php’:

<?php
'<p>' . $comment->get_error_message() . '</p>'

An example of the Html code generated:

<p><p><strong>ERROR</strong>: please fill the required fields (name, email).</p></p>

The reason is that in function _default_wp_die_handler, line 3072 in ‘wordpress/wp-includes/functions.php’ (WordPress 5.2.1), there already is a paragraph tag.

<?php
$message = "<p>$message</p>"

I would suggest removing the paragraph in ‘wp-comments-post.php’. Simply:

<?php
$comment->get_error_message()

ought to do.

Make sense

Thanks. The fix works for me. To be honest, I removed the tags in my source in release 5.1.1 some weeks ago. I noticed them again while updating to 5.2.1 yesterday. Good.

Thanks @tnbnicer and @dkarfa, this looks good. I also opened #47580 to address the overall problem with invalid HTML in wp_die() output as it looks like this is something that happens in many areas of core. This particular case was introduced in [36424].
