I need to use drupal_add_css to call stylesheets onto single Drupal 6 pages. I don't want to edit the main theme stylesheet as there will be a set of individual pages which all need completely new styles - the main sheet would be massive if i put it all in there.
My solution was to edit the page in PHP editor mode and do this:
<?php
drupal_add_css("/styles/file1.css", "theme");
?>
<div id="newPageContent">stuff here in html</div>
But when I view source, there is nothing there! Not even a broken CSS link or anything, it's just refusing to add the CSS sheet to the CSS package put into the page head.
Variations don't seem to work either:
drupal_add_css($path = '/styles/file1.css', $type = 'module', $media = 'all', $preprocess = TRUE)
My template header looks like this, I've not changed anything from the default other than adding a custom JavaScript.
<head>
<?php print $head ?>
<title><?php print $head_title ?></title>
<?php print $styles ?>
<?php print $scripts ?>
<script type="text/javascript" src="<?php print base_path() ?>misc/askme.js"></script>
<!--[if lt IE 7]>
<?php print phptemplate_get_ie_styles(); ?>
<![endif]-->
</head>
Why is this function not working?
Answer was very much to use the CSS Injector module - great little addon!
Here is an excerpt from its project page:
Allows administrators to inject CSS into the page output based on configurable rules. It's useful for adding simple CSS tweaks without modifying a site's official theme. The CSS is added using Drupal's standard drupal_add_css() function and respects page caching, etc. The 2.x brach leverages CTools so CSS can be included with Feature changes (ie. CSS that improves the look of a View can be packaged with the View).
