Validating and email address

[Dawg]

Here is my code:

$contact_email = strtolower($_POST[contact_email]);

if ($contact_email == "")			
			{
				$msg .= "<strong>Enter your email!<br></strong>";
			}
		elseif ($contact_email > "")
			{
				$int = (ereg("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $contact_email));
				if ($int == 0)
				{
					$msg .= "<br><strong></strong><strong>Invalid Email! Please include a @ and use a .com, .org or .Country(ie .au, .tr) type address</strong><br>";
				}
			}

I am using this code in two different pages (I know I should have a function that I call). When a user types his address in upper case I change it to lower. One page it works fine and I get no errors. The other page does not like it at all and returns the error after validating.

Thanks

If you have an error on some line (like 55) where you leave off a semicolon, quote, parenthesis, or bracket, PHP will often tell you that you have an error on some later line (like 100). This can make troubleshooting confusing when there's clearly nothing wrong with line 100. Take a look at the rest of your script. You left out a semicolon or something.

I should have said that the code works but after validating it returns the message
"Invalid Email! Please include a @ and use a .com, .org or .Country(ie .au, .tr) type address" it thinks the address is wrong, But the only thing is the valid email address is typed in all uppercase.

Try changing this

$POST[contact_email]

to this

$_POST['contact_email']
