If you are trying to add a custom tab to the product add/edit page in Magento admin, then you are at the right place. Today I will tell you a damn simple method to add the custom tab to product add/edit page. We will have to add few lines to the xml layout file of your custom module. Then create a phtml file that contains the html part to be shown in the tab.

As a Magento developer you frequently encounter the Configuration page of Magento admin backend. But have you ever noticed how these configuration pages are created and where are those configuration options saved? If not don’t worry, today I will tell you how to create an admin configuration page for you custom module. You might wonder that their is no ‘.phtml’ involved in this configuration page. Shocked! Its ok, we have to play only with the xmls to create this functionality. So now lets start the development.

Sometimes we need to add some static configuration options inside our project that will be accessible from whole project scope.

For example, I wanted to define some custom DateTime format that I will use in more then one bundles to format my output to mobile device.

I didn’t want to write format string again and again in code, because after 2 years as my project expanding, I maybe will not be able to quickly find where I defined that output format to reuse it.

Magento Provides the manage customers feature to list and edit the customers information.
The Customer edit page in the admin panel gives details about the customers account information,address,orders etc.

In some scenarios we may need to show our custom module contents related to the customer in a additional tab. To achieve this functionality we need to create a custom module and add our tab.

Step 1: We start with our config.xml file. In this file we are specifying an adminhtml xml layout file and a Block class for our custom module.

app/code/local/Mydons/etc/config.xml

Magento Provides the default customer registration form with very few fields like name,email,pwd etc. But in realtime we need to get more details from the customer during registration. In order to achieve this we may have to create custom module that extends the magento customer module.

Step 1: We Start with Our module activation file first it just specifies the module name its location and Active Status. This file must be placed in app/etc/modules/ directory as app/etc/modules/Mydons_Customer.xml
