title: Adding Custom Theme Templates in Drupal 7
date: 2012-04-19
excerpt: >
Today, I had a situation where I was displaying a list of teasers for news article nodes. The article content type had several different fields assigned to it, including main and thumbnail images. In this case, I wanted to have different output and fields displayed when a teaser was displayed compared to when a complete node was displayed.

However, I decided to do something different and create a separate template file just for teasers. This is done using the hook_preprocess_HOOK function that I can add into my theme's template.php file.
However, I decided to do something different and create a separate template file

The function requires the node variables as an argument - one of which is theme_hook_suggestions. This is an array of suggested template files that Drupal looks for and attempts to use when displaying a node, and this is where I'll be adding a new suggestion for my teaser-specific template. Using the `debug()` function, I can easily see what's already there.

Now, within my theme I can create a new node--article-teaser.tpl.php template file and this will get called instead of the node--article.tpl.php when a teaser is loaded. As I'm not specifying the node type specifically and using the dynamic <em>$node->type</em> value within my suggestion, this will also apply for all other content types on my site and not just news articles.
