Banning free email providers

[Anne]

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

[Nibbler]

Yes. You need to edit your register.php

find:

Code Select Expand

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 Expand

$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.

[Nibbler]

You need to do that in your forum.

[Leny]

Thank you very much Nibbler!

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

Could this be made more general by doing for example:

Code Select Expand

$banned = array(
'@hotmail.',
'@yahoo.',
'@msn.',
'@gmail.',
'.info$',
'.biz$'
);

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

[Nibbler]

Try

Code Select Expand


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


[wuurp]

oops.

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

Thanks.

[wuurp]

Try

Code Select Expand


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 Expand

if (preg_match('/\.(info|biz)$/', $email)) $error .= '<li>' . 'Registration not permitted from this tld.';

since it's no longer in that foreach loop?

[Nibbler]

Yeah. I copied too much code.

[Mimer]

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

Code Select Expand

$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;
}
}
