Listing and Checking Drupal Permissions through Code
The following lists all the permissions available in Drupal.
<?php
// Render role/permission overview:
$options = array();
foreach (module_list(FALSE, FALSE, TRUE) as $module) {
print_r($module);
// Drupal 6
// if ($permissions = module_invoke($module, 'perm')) {
// print_r($permissions);
// }
// Drupal 7
if ($permissions = module_invoke($module, 'permission')) {
print_r($permissions);
}
}
?>
You could check whether a particular permission is set or not using the following:
<?php user_access($string, $account = NULL) ?>
