Join Jon Peck for an in-depth discussion in this video Creating a custom permission, part of Drupal 7: Custom Module Development.
Similar to help, permissions can be created with a hook. …In particular, Drupal 7 uses hook_permission which applies permissions defined in a module …so they can be used from the user permissions page along with granting or restricting who …can execute actions. …Hook permission returns an array in a standardized format. …Looking at the API documentation I can see that hook permissions takes no parameters. …So the only thing I need to do is generate the array structure. …Though hook_permissions array consists of a key that contains the name of the permission …followed by a nested array definition that contains at the minimum two key value pairs.…
A title and description each passed through the t function. …There are additional options, but they are used internally and rarely. …Open the IDE and navigate to the windfarms.module, start with an appropriate doc block for the …new hook which implements hook permission. …Create a new function named windfarms permission. …Hook permission takes no parameters. …

Q: gmap3_tools is not working the way I expected it to. What version of gmap3_tools should I be using?
A: Use the free exercise file containing the version of gmap3_tools used for recording; the published version of the module on drupal.org has changed since recording and is not backwards compatible.
Q: I attempted to run the Drupal site root from the project files, but the site isn't loading. Why not?
A: The Drupal configuration file in sites/default/settings.php contains database configuration specific to the environment used to record the movie. This may be different than your environment. Edit the file and search for "windfarms" - you may need to change the database host, username, password, db name and port to match your specific environment.
