Provide pattern and suggestion theme templates from a module
六月 16th, 2009 | posted by Alpha Epsilon Delta

Pattern and suggestion theme templates normally can only reside in the theme directory. This can make the theme folder filled with many many templates that can sprawl over time. This makes sharing templates between active themes impossible, switching theme or upgrading theme very hard. It would be much better to house these templates inside a module or inside some site/files folder. This makes module fully able to provide override theme templates out of the box. No copying files to theme necessary.
Here is the code to make this happen, which basically makes a module behave like a theme as far as theme template override goes:
function hddigitalworks_theme_registry_alter(&$registry) {
// point to where the templates are. This can be anywhere
// like inside the site files directory
$path = drupal_get_path('module', 'hddigitalworks') . '/templates';
// pretend we are a theme, go discover pattern templates in our module directory
_theme_process_registry($registry, 'phptemplate', 'theme_engine', 'hddigitalworks', $path);
}
The _theme_process_registry() auto-discover any templates and add them to the theme registry. It is a core internal function (the under-score in front). Using it here is probably not very kosher. Unlikely to change within one major drupal version, I hope (famous last word).
The code handles both suggestion templates and pattern templates. Views and Webforms make use of pattern templates. Suggestion templates are described in template suggestions? But there is not much information about pattern template are available. The hook_theme() api doc describes the 'pattern' key but doesn't go in any details. The views module is a very good place to learn how to create and use pattern template hooks. Both kinds of templates serve the same purpose: enable template override of a given theme hook. The reason to use pattern template is performance. Pattern is matched during theme register build and they turn into new theme hooks base on the file pattern in the original hook's "pattern" key. At runtime, the theme() call is invoked with an array of hook names and the corresponding hook info is directly found out of the theme registry. Whereas template suggestion must be searched subtheme(s) to base theme, etc, which can take time because it involve file system access. So for high performance theme hook needs override, pattern template is better.
I wanted to have a unique
I wanted to have a unique simple html flash page posted while working on the site.
I posted the above function into my themes/garland/template.php the redirect works well.
however, i cannot access the admin page to work on the site..
Should the code be added to
Should the code be added to the current theme's template or the template of the other theme one wants to use for the content type? Where do you pick the theme once you add the code to the template? Also does the devel_theme module need to be enabled to use this? Thank you for any help in advance.

The variation of templates is
The variation of templates is important to me. Being able to switch from one to another seamlessly can save valuable time. How reliable are template suggestions, and do they follow protocol when meeting conditions specified? Even if they do, it still seems a bit rigid to me, in that they only arrive at point X if conditions a-z are apparent. If the code above can override specific theme hooks, then this should create a more flexible environment when searching for and switching between templates.
