Template suggestions based on Path alias

I created a module called alias_suggestion and put this single function in the alias_suggestion.module file. With this method you do not have to add a menu hook for every page you want to theme. It just works for every page.

It depends on Path being activated.

Here is the alias_suggestion.info file

Hope this is useful.

thanks!

unfortunately it doesnt seem to work for me...

Hi
I created the 2 files, .module and .info. But when I upload the zip file containing that module, it says, there is no .info file. I have checked, and it is there.
I have Drupal7, is there something missing?
thanks

I did something like this on my last site, but this was a little bit more complex than mine, I didn't care about the different types of levels for every path. Thank you for your great work man, wonderful :)

The version posted by the author didn't work for me.
First, there is a missing / in the second line (reported previously).

Second, it wasn't working for URLs with hyphens (my-section/my-page), as the string added to the theme_hook_suggestions array would look like this: page--my-section__my-page, which for some reason, at least on my installation, just fails: the corresponding template is never found/applied.

The way I fixed it was by replacing hyphens (-) to underscores (_) just before the string is added to the array. I've also applied this fix posted previously which may look unnecessary (although it's more correct to keep it fixed) as, as said, the hyphens are finally replaced with underscores just before adding them to the array.

This is the final code:

function alias_suggestion_preprocess_page(&$vars, $hook) 
{
  // only do this for page-type nodes and only if Path module exists
  if (module_exists('path') && isset($vars['node']) && $vars['node']->type == 'page')
  {
    // look up the alias from the url_alias table
    $source = 'node/' .$vars['node']->nid;
    $alias = db_query("SELECT alias FROM {url_alias} WHERE source = '$source'")->fetchField();

    if ($alias != '')
    {
      // build a suggestion for every possibility
      $parts = explode('/', $alias);
      $suggestion = '';
      foreach ($parts as $part)
      {
        if ($suggestion == '')
        {
          // first suggestion gets prefaced with 'page__'
          $suggestion .= "page__$part";
        }
        else
        {
          // subsequent suggestions get appended
          $suggestion .= "__$part";
        }
        // convert hyphens to underscores.
        $suggestion =  str_replace('-', '_', $suggestion);
        // add the suggestion to the array
        $vars['theme_hook_suggestions'][] = $suggestion;
      }
    }
  }
}

Hope this helps someone out there.

It works fine for me. Thanks for the instructions.
