Email Validtation

[sparky11]

I am Looking for some hel on email validation for a specific domain Like say [e-mail]

I want only people with the @.dom address to beable to register.

I have looked through the forums and found regular email varifications that will verify anyone but not one for a specific domain
Any help would be great

thx

use strpos and substr to get the part of the email id after @ and compare it

That was great but Could you please supply some code I am still confused on this issue 😃 thanks for all the help

well here is an explanation step-by-step, im sure u can write the code
$email = "[e-mail]";
$position = strpos($email,"@"); // gives location of @

u have the string which is $email and the position $position, use the function to extract "yourdomain.com" from "[e-mail]". using substr()

http://ca.php.net/manual/en/function.substr.php

now u have the domain, check using if-statement to see if it matches the domains allowed

try it, if u get errors then get back wiht ure error and code

couldn't I just doo something as simple as this

function validate_email ($address) {
	return (ereg('^[-!#$%&\'*+\\./0-9=?A-Z^_`a-z{|}~]+'. '@'. '[me]+\.' . '[com]+$', $address));
}

or am i just being silly 🙂

well i usually stay clear of regular functions, but if u think it works then go ahead.
You can do what i suggestedi in 1 line of code but since u posted that u didnt understand substr() and strpos() i figured to explain it to you and u could then write it .

the function u wrote just checks if an email id is valid, not if it matches the domain u want
