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?

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).

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

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.

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.

Thanks for the link, wyrmmage. That's very useful. I think the rest of the code in the page is unneccessary. You probably just need these since drupal 6 already automatically check for file existence:
drupal_add_css(path_to_theme() . '/css/yourcss.css', 'theme');
// Add the following to regenerate $styles.
// This is needed for template_preprocess_page() since css is already generated at this point.
$variables['styles'] = drupal_get_css();
