add css if url contains

Question

I have one node type and two page types for this node.

http://site.com/themes/*

and

http://site.com/years/*

And i want to hide one of the "view-filed" in all "years" pages using the css.

Found this but it doesn't work

function mythemename_preprocess_page(&$variables,$hook) {
  $alias = explode('/',drupal_get_path_alias(request_uri()));
  if($alias[1]== "years") {
   $vars['theme_hook_suggestions'][] = 'years';
  }
}

I would be very grateful for any help.

Answer 1

Here's how I would do it (but I'm rather new to this, so maybe your approach is better)...

function mythemename_preprocess_page(&$vars, $hook) {
  if (arg(0) == 'years') {
    drupal_add_css(path_to_theme().'/css/years.css');
  }
}

Answer 2

I would suggest doing this with pure CSS selectors.

I'm pretty sure you can do something like this:

/* Hides the link text. */

a[href*="find_this_part_of_URL"] {

display: none;

}

I suggest you do NOT hide page content with this CSS, as it is bad for search engine optimization, but if you honestly can't get the theme to cover up a link, so you can focus on fixing the theme hook, use the above code.
