How can I save the customer's login & registration form data in my log?

Question

I want to add the form data in log files when the customer submits the login/registration form on my Magento 1 store. How can I do it using login.phmtl and register.phtml template files?

I am using Magento ver. 1.9.4.4

I tried using the below method but not working.

<?php
    Mage::log(print_r($formData, 1), null, 'logfile.log',true);
?>

How do I fetch the data of form i.e. Customer's name, email & password in the $formData variable?

I just want to know that is the form is submitted successfully or not.

As the login and signup are not working on my Magento 1.9 store.

Easier is to override the customer controller, you also just check for an ID instead of a log. check if the user gets an entity_id after save, which you can also find in this controller. Templates don't work well for this.

Here is an explanation on how to override the controller: How to override default Magento (1.9.2.4) controller /customer/account/create with controller in my module?

Don't forget to disable this when you're done with debugging, this data is sensitive.
