On this site I use the Comment Validation plugin from Jörn Zaefferer.

You can find out more about this plugin at the WordPress directory.

This plugin is an amazing plugin, but the new version breaks W3C validation. Mostly due to typo’s and small oversights. Lets take a looks at the original comment-validation.php file in version 0.3.

function commentValidation() {

echo '
';

echo '';
echo '';
echo '';

}

add_action('wp_head', 'commentValidation');

Hey, where you able to tell what need to be fixed? Well lets take a closer look.

Corrections

On line 15 you’ll see we need to change the closing tag to fit the link attribute and not a script. Since there is not closing link, will end it with a forward slash, we also we need the type attribute.
From this:

echo '/wp-content/plugins/comment-validation/comment-validation.css">';

To this:

echo '/wp-content/plugins/comment-validation/comment-validation.css" type="text/css" />';

That was pretty simple.. So I am also going to add a few lines that will return the code to a new line, so that my final code looks a little cleaner, this is something you don’t have to do.

Here is my example:

echo '/wp-content/plugins/comment-validation/comment-validation.css" type="text/css" />';
echo "n";

The n will return a new line..

I also don’t need the code on every page so I have added in a conditional code of is_singular. You can view the final code below.

So here we see the final in total. Remember I’ve added a few lines that you may not want to add or use:

function commentValidation() {

if (is_singular()) {
echo '
';
echo "n";

echo '';
echo "n";
echo '';
echo "n";
echo '';
echo "nn";

} else { return; }

}
