Writing your own Prestashop Module – Part 4
Posted by admin | Filed under Tutorials
Form Validation and Security
Introduction
While being sufficiently functional for what it does, the module we created in Part 2 does present us with some issues to consider when implementing “real world” modules to extend Prestashop. In particular the user input we captured with our form was written directly to the configuration entry without any checking to determine whether it was valid, nor did we take account of the type of data being entered.
In this tutorial we will look at the general issue of form input checking and security, both for Back Office and Front Office forms and user input as well as looking at improving our code both functionally and aesthetically.
