Extract email address domain from $_POST

[sks1024]

I have a script that takes form data and posts to a DB. I have someone that is doing alot of fake posting and using weird email address all with my domain as part of the email address that they use. How can I use and if statement to ask if the domain is mine from $_POST[email] then do not allow the post if the domain is mine?

Thanks

it would be helpful to see the code that handles your posted data, but let's assume that the email address submitted is contained in $_POST['email'].

<?
$my_domain = 'mydomain.com';

if (stristr($_POST['email'], $my_domain) {
  die( "YOU JERK.  YOU ARE NOT PERMITTED TO POST AN EMAIL ADDRESS FROM MY DOMAIN");
}

?>

This works great but forgot one user needs to post with the email address of [e-mail]

so try editing the code i gave you. it's not particularly hard to get that code to accept [e-mail] but refuse anything else at mydomain.com. if you can't do it, i would recommend buying a book on PHP and reading it or perhaps going php.net and reading the docs there.

what about if this jerk user posts using [e-mail]? how will you distinguish that from the one valid user? sounds like you need a registration process which would be much more involved.
