Banning free email providers
« on: April 11, 2005, 12:39:55 am »

Is there any way to prevent people from registering using a free email provider (ie. Hotmail, Yahoo, etc.)?

Yes. You need to edit your register.php

find:

Code: [Select]
if (!eregi("^[_\.0-9a-z\-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,6}$", $email)) $error .= '<li>' . $lang_register_php['err_invalid_email'];
and add after it:

Code: [Select]
$banned = array(
'hotmail',
'yahoo',
'msn',
'gmail'
);

foreach($banned as $ban){
if (strpos(strtolower($email), "@$ban.")){
$error .= '<li>' . 'Registration not permitted from free email providers.';
break;
}
}

You can change the array of banned providers and the rejection message as required. You could also change the message to use $lang_register_php['err_invalid_email'] to give a general message of 'invalid email' in the user's language if you prefer.

This will not work for bridged installs.

what about the opposite?  Is there any way I could only allow certain users (i.e. with email addresses from my school) to register?

Hi folks.
I have CPG 1.4.10 & BBH 2.0.21 bridged working fine.

Im looking for something that keep out certain domains (like 10minutemail.com or mailinator.com) from registering.

Reading this post and another one (Makc666's) I can't see solution for me but I think should be nice have an editable "blacklist", or something like that, in next releases of CPG (or some plugin).

Im just writing ideas, no solutions, i know.  :-\

Going back... anyone knows how can I ban domains having bridged system?  ??? Thanks.

You need to do that in your forum.

What about blocking certain tlds, like .info or .biz?

Could this be made more general by doing for example:

Code: [Select]
$banned = array(
'@hotmail.',
'@yahoo.',
'@msn.',
'@gmail.',
'.info$',
'.biz$'
);

foreach($banned as $ban){
if (strpos(strtolower($email), "$ban")){
$error .= '<li>' . 'Registration not permitted from free email providers.';
break;
}
}

Try

Code: [Select]
if (preg_match('/\.(info|biz)$/', $email)){
if (strpos(strtolower($email), "$ban")){
$error .= '<li>' . 'Registration not permitted from this tld.';
break;
}
}

oops.

Of course. My brain was still thinking about the eregi from the previous line, not strpos.

Thanks.

Try

Code: [Select]
if (preg_match('/\.(info|biz)$/', $email)){
if (strpos(strtolower($email), "$ban")){
$error .= '<li>' . 'Registration not permitted from this tld.';
break;
}
}

Should this actually be more like

Code: [Select]
if (preg_match('/\.(info|biz)$/', $email)) $error .= '<li>' . 'Registration not permitted from this tld.';
since it's no longer in that foreach loop?

Any chance I can use this code in CPG 1.5.16?
If so, where do I put it?

Code: [Select]
$banned = array(
'hotmail',
'yahoo',
'msn',
'gmail'
);

foreach($banned as $ban){
if (strpos(strtolower($email), "@$ban.")){
$error .= '<li>' . 'Registration not permitted from free email providers.';
break;
}
}
