Duplicate <meta> in Drupal variable $head

Question

Hey Everyone,

I am trying to customize the $head variable in my page.tpl.php template, because there are two instances of

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

appearing, which I believe is affecting the site from being validated using W3C's Markup Validation Service. Any help would be much appreciated, thanks!

Answer 1

Well, first of all I'd try and figure out WHY you're getting duplicates of that. Manually removing one is more of a hack than a fix.

That said, you can customize $head using template_preprocess_page. In your theme's template.php, do something like:

<?php 
function THEMENAME_preprocess_page(&$variables) {
    // use $variables['head'] here and do whatever you want with it, such as...
    $variables['head'] = str_replace('blah blah','blah',$variables['head']);
    // ...although that's completely untested and might not work
}

This seems to be a bug in the Drupal API, the discussion can be followed here:

Seems that even drupal.org is duplicating the content type meta tag.
