Inject variables only in teasers (template suggestions)

Question

How could I detect if node type is article (in template.php) but process variables only for teaser of article, not article i full mode. (I have template suggestions so i have node--article-teaser.tpl.php). Like:

if ($node->type == 'article' and inject only if article-teaser.tpl.php)

Thanks!

In a preprocess/process function for the node template file, you just need to check the following variables:

• $variables['teaser'] must be TRUE
• $variables['node']->type must be 'article'

$variables is the parameter passed to preprocess/process functions.
