When i started with web development the first language i touched was PHP, i started creating simple form data inputs with some fields like:
- Phone number
And yes, they “work” but what happens when the users give us wrong data? and we dont want to use HTML’s validation tags because they are unsafe.
So i’ve decided to create my own Validator (no, not like Laravel validator).
So… lets start.
For this you must know the basics of:
- PHP 7.x
First of all we need a basic form with some fields (create your own or just copy it from below).
Let’s create our class helper Validator.php
Nice! so let’s work on our someAction.php file.
Great! we only need to display those errors on login.php file adding some php script.
And thats how we created our own validator in PHP.
