Chapter 17. JavaScript and PHP Validation and Error Handling
With your solid foundation in both PHP and JavaScript, it’s time to bring these technologies together to create web forms that are as user-friendly as possible.
We’ll be using PHP to create the forms and JavaScript to perform client-side validation to ensure that the data is as complete and correct as it can be before it is submitted. Final validation of the input will then be made by the PHP, which will, if necessary, present the form again to the user for further modification.
In the process, this chapter will cover validation and regular expressions in both JavaScript and PHP.
