RegEx Case Sensitivity
 

Version 4.1.10

^[A-Z][A-Za-z]+\.[A-Z][A-Za-z-]+$

I'm trying to force Firstname.Lastname or Firstname-Lastname-Lastname with the first letter being forced to a capital letter. But it seems as if the code autimacially puts the lower case i at the end of the preg_match string to ignore case.

How can I remove the "i" from the preg_match code so I can force case sensitivity?

In includes/class_dm.php, function verify_username() around line 456 is this:


I think that's where you'd want to remove it. Another approach might be to use a plugin on the registration page to change the username that's entered, or even build it from first name/last name fields.

That worked perfectly. I just removed the 'i' from the '#siU'

Note: The file name was includes/class_dm_user.php

Thanks for your help!

Oops...sorry about that. It's actually in both of those files, but I don't know when the one in class_dm.php would be used.
