I am trying to use if preg_match but I am not to good at regex. I was wondering how I can do this:

 

I have a form and the name of an input is username_required, I am trying to check to see if _required is in the name. How do I do that? Thanks

You don't need regex for this.

<?php
$field_name = "username_required";
if (strpos($field_name, "_required") !== FALSE) {
//it's there
}
else {
//nope
}

DarkWater's is better as it uses less resource but..

if you wanted a regex to check if it ended with "_required" then the below would work

 

if (preg_match('/_required$/i', $field_name))
{
//it's there
}
