Sometimes you may need to let customers manage products section in your store BUT limit their ability to delete them. However, by default, Magento allows you to change only one permission that called ‘Manage product’. That’s quite a limitation and doesn’t allow us to solve this problem.

Read on to learn how to create additional permission, like ‘Add’, “Edit’, or ‘Delete’, etc.

We’ve created a little module with an observer and a new ACL rule that will let you extend the default Magento functionality.

Here is the adminhtml.xml file:

Also, we added a new ACL ‘Manage Products’ section with the ’Delete Products’ section inside.

You can repeat this for other actions that you may want to limit for customers.

Then, we need the observer where to check if the action is permitted or redirect the Admin back if not. As in the previous case, you can extend this functionality.

Declare the observer in the modules’ config.xml file in the adminhtml section:

We’ve used two known actions to delete products: simple delete and delete with mass clearance. Both are available in the products grid.

The same observer and its method is used because there are no differences between the checks and result. When expanding this functionality, keep in mind that the observer’s name should be unique (delete_product_acl and massdelete_product_acl in our case).

Now, we need to complete the method in the observer.

Here is the Observer.php file:

Let’s look through this method line by line:

We got the validation result for the current Admin using our ALC for ‘Delete’.

In case you are logged in under Superadmin, the check will be ignored and always return ‘true’. That’s why it is required to create a new Admin (but not Superadmin!) to run the check.

Next goes the if (!$isAllowed) check.

If it is successfully passed and the rule is not available to the current Admin,  reset the following execution of the current action for the current Controller. Also, give the redirect back in response to the index action of the current Controller with the ‘Delete action is not allowed’ error display.

You can change the redirect page by replacing the path $controller->getUrl(‘*/*/’) to any other, where the first * is route, and the second * is controller. The third and missed * is the controller’s action, when we miss value like in the example it is indexAction.

You can change the result and show 404 page, for example, or send an email to the Superadmin about the actions of the current Admin.

Hence, the basics of such a module are quite obvious and the following development is limited only to one’s development resources.
