Restricting registration to specific email extensions

[danielmeade]

Hi, I'm after a script that will allow me to restrict user registration to certain email extensions. i.e .edu

Any help on this is much appreciated!

Usually a regular expression is used to validate that the email is of the proper format and you could restrict the extension inside the expression also. I am just learning regular expressions so I can't give you a code example that would work but I know it's probably one of the better ways to do it.

Since you asked in the php section I presume you want it in PHP.
I suggest php explode and array count.

$split = explode($email,".")
if($split[count($split-1)]=="edu") {
    # acceptable email, put code here for that
} else {
    # unacceptable email, put code here for error returns
}
