[SOLVED] validate an email form text filed

[monkeybidz]

How would i run a check in my datacheck page to see if the user entered an email address in a form text field?

 

if(empty($email_address) || - NOT VALID EMAIL STUFF HERE -){

  $msg[] = $error12;

}

this will check if is a valid syntax, but your need to email them to see if the email is their valid email, or check the domain to see if its a valid domain..

 

 

<?php
if ( !preg_match('/^\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b$/i', $email_address) )
{
$msg[] = $error12;
}
?>

 

EDIT:

'[email protected]' = valid (without quotes)

'[email protected] ' = invalid (without quotes) (note the space at the end

'' = invalid
