Validating the form, before create user in database

[flap]

Hello everyone, i'm looking for some best or most used way to validate a form data.

I saw something with regexp used and preg_match, also i saw something like filter_input.

 

What's the best way? I have only 3-4 fields in form. Login, email and password.


Have a good day

Email addresses can be validated with filter_var or filter_input. Password "validation" depends on what you want to do but, yes, typically regular expressions are involved.

We can give much more precise answers if you can give us much more precise questions. Exactly what do you want it do?

Typically you'll want to validate twice; first you validate on the client side in order to give immediate feedback to the user, and the you do it server-side to verify the data and protect the overall system.
