Restrict user email on registration

**grynmoors** · 05-20-2009, 06:03 AM

I'd like to see a feature where the administrator can restrict certain email domains from being used when people register, in the same fashion that administrators of bulletin boards have. You can put in a particular address or an entire domain like *@yahoo.com or *@hotmail.com, etc.

One I'd like to block in particular is Yahoo! because they are overly paranoid. They tend to block a lot of legitimate emails and then you have to jump through all kinds of hoops to get them to unblock you.

Well, I got enough to do than jump through their hoops. I need to restrict the use of yahoo.com addresses from registration. I don't want to block users who are already signed up and using yahoo, I just want to block future registrations, since that is the email that their new account details and the activation link is sent to.

Thanks.

Code:

 $email = $_POST['email'];
$email = parse_url($email);
$email = $email['host']

if ($email == "yahoo.com" || $email == "hotmail.com"){

echo "The administrator has chosen not to accept email addresses from Yahoo and Hotmail";

echo "<a href=\"javascript:history.go(-1);\">
    <b><font size=\"2\">&lt;&lt; Previous page</font></b></a>";
exit();
}

Yes, something like that except maybe with an alert dialogue that pops up when they hit submit: "Email addresses from this domain are restricted. Please use an alternate email address" (some similar wording) that they have to click "ok" to.

...and a spot in admin panel were the administrator can enter in the domains he/she wants to "ban" from registration (like they have in most forum admin panels).

I try to avoid too much javascript, direct code is much faster

You can add a column to the config table with stored emails then use this script to check it

A better way for all these mods is to write an autoinstaller like phpbb has, that way ppl can pick and choose what goes in and stays out.
