Drupal 7 Module Development Tutorial #11 - Using Template_Preprocess to Change the Flag Link

In the final video tutorial of this series on Drupal 7 module development, I show you how we can disable the link for our flap application depending on how the site administrator has configured the module which we covered in tutorial 10. In doing so, I introduce you to template_preprocess functions which allow us to modify changes made by the flag module before content is actually output.
