How_to_granulate_permissions_on_each_field 63 How_to_granulate_permissions_on_each_field ==How to granulate permissions on each field== To reach this aim, there is the method fieldname__permissions to place into the delegate class of the table. ===Getting the role=== First it is necessary to know the user's role. For this, the method getUser() is added in the class : <code>function getUser(&$record){ $auth =& Dataface_AuthenticationTool::getInstance(); $user =& $auth->getLoggedInUser(); return $user; }</code> ===Setting up the permissions for each field=== Next, the permissions are built for each column or field where they are needed, like in this example where the method name is formed with the field name, followed by 2 underscores then by ''permissions'' : <code>function fieldname__permissions(&$record){ $the_user =$this->getUser($record); $user=$the_user->val('identifiant'); if ( !$user) return Dataface_PermissionsTool::NO_ACCESS(); if ( $user=='demande' ){ return Dataface_PermissionsTool::ALL(); } elseif ($user=='admin'){ return Dataface_PermissionsTool::ALL(); } else { return Dataface_PermissionsTool::READ_ONLY(); } }</code> === Also See === * [[viewable_editable_fields]] - How to make a field editable for some users and only viewable for some other users * [[no_access_text]] - Replace the default NO ACCESS permission text with another text. * [[__field__permissions]] - Returns the default permissions for a field of a given record. * [[Delegate_class_methods#toc5|Permissions]] - other Delegate class methods en 0
