i'm developing an app that i intend to run on a client's intranet. i want to ensure that only email addresses with the client's domain should be registered. how do i achieve this using regular expressions?
Are you using PHP 5.2 or above?
If so, you could use to validate the email address as a whole:filter_var('firstname.lastname@example.org', FILTER_VALIDATE_EMAIL);
And then using strpos and substr extract the domain element and do a string comparison to restrict the domain.
if you like use jquery funcution email validata . very sample just you search email validation jquery function .
thanks @blocblue, it's now working the way i want it to
