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).

It is not quite clear where you are selecting the template that you have in your example. If you are selecting it from a module then you can just use drupal_add_css in the module rather than the template.

If you have your own theme you can use template_preprocess_page and put logic in there to add the relevant CSS (you can also use it to select the template to use).

Solution 3

I have noticed something weird and it might fix your problem:

drupal_add_css( drupal_get_path('theme','themname') . '/working.css','module' ,'all' , false );

drupal_add_css( drupal_get_path('theme','themname') . '/path/to/folder/notworking.css','module' ,'all' , false );

The first one will work ebcause the style it in the main them folder The second line will not work because the style is in a sub folder !

Edit:

i think it did not work because i did not write the path the the style file properly :S so please disregard my answer

drupal_add_css( drupal_get_path('theme','test') . '/pages/subpage/style.css','theme');

is working

Solution 4

This function wont work in templates. The reason is that the variable $styles which will hold all the stylesheet html will already have been generated at this point, so drupal_add_css wont work as it adds to that. if you want to do this in your theme, you would probably have to add the css file manually

<link rel="stylesheet" ... />

The other way would be to use drupal_add_css in a module, but you might have a hard time adding the correct css files on the pages you want.

Solution 5

It's possible to use drupal_add_css() inside your template.php file; this page has a good example of how to do just that.

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>    
    
</head>
```
Why is this function not working?

really? I had this working a week ago on another site :o - I'd edited drupal_add_css into a page in PHP mode.

I think you are right as to why the function won't work but wrong that it can't be done in the theming layer. See my answer.

Another note to this, if you use template_preprocess_page with drupal_add_css() make sure you add force it into the styles array like so: drupal_add_css(path_to_theme(). "/css/page.css", "theme"); $vars['styles'] = drupal_get_css();

I would add that the function can be made to work in some templates and preprocess functions. What it won't work in is the page.tpl.php or hook_preprocess_page, because by then you're too late: the $styles variable has already been compiled by phptemplate_preprocess_page() (NB D6 terminology; D7, probably html.tpl.php and phptemplate_preprocess_html().)
