[SOLVED] If statement to check email variable

[denoteone]

I need to make an if statement that checks to see if my variable $_POST['email']  has @mysite.com  in it.

 

 

if (!get_magic_quotes_gpc()) {
$_POST['email'] = addslashes($_POST['email']);
}

 

this is where I need to make sure that the email has @mysite.com in it. If not then die('Your email must end in @mysite.com');

 

$usercheck = $_POST['email'];
$check = mysql_query("SELECT email FROM users WHERE email = '$usercheck'")
or die(mysql_error());
$check2 = mysql_num_rows($check);

//if the name exists it gives an error
if ($check2 != 0) {
die('Sorry, the email '.$_POST['email'].' is already in use.');
}

Check the RegEx forums, they have stickies that point to common expressions you can use.

I'd do something along the lines of

 

$emailpieces = explode('@', $usercheck);

 

if ($emailpieces[1] != 'mysite.com') {

die('Sorry, that email is invalid.');

}

thanks for the help what are the RegEx forums is that a separate site?
