[SOLVED] block email addresses or domains on signup

[NSW42]

Heya all,

 

just need some help or ideas on registration with emails, what id like to have is block certain email addresses or domains when users join up, so if its a certain email address it says when they click signup that email address is not allowed or valid any help would be appreciated, some coding below to help out.

 

 

Many Thanks

 

if((!isset($email_address)) ||

  (!isset($username)) ||

  (!isset($nickname)) ||

  (!isset($password)) ||

  (!isset($password2)) ||

  ($password!=$password2) ||

  (!ereg("^[A-za-z0-9]+$",$_POST['username'])) ||

  (!ereg("^.+\..+$",$_POST['email_address'])) ||

  ($checku > 0) || ($checkn > 0)|| ($checke > 0))

{

                          print("Please fix the following.<BR>");

if(!isset($_POST['email_address']))

{

print("Enter a email address.<BR>");

}

if(!isset($_POST['username']))

{

print("Enter a username.<BR>");

}

if(!isset($_POST['nickname']))

                          }

if(!isset($_POST['password']))

{

print("Enter a password.<BR>");

}

if(!isset($_POST['password2']))

{

print("Enter a confirm password.<BR>");

}

if($_POST['password']!=$_POST['password2'])

{

print("Password and confirm do not match!.<BR>");

unset($password);

unset($password2);

}

if(!ereg("^[A-za-z0-9]+$",$_POST['username']))

{

print("Enter a Valid username with letters and numbers only.<BR>");

unset($username);

}

if(!ereg("^.+\..+$",$_POST['email_address']))

{

print("Enter a valid email address.<BR>");

unset($email_address);

}

if($checku > 0)

{

print("Username already in use!<BR>");

unset($username);

}

if($checkn > 0)

{

print("Nickname already in use!<BR>");

unset($nickname);

}

if($checke > 0)

$BlockedNames = array('blah', 'bleh', 'something');
$BlockedDomains = array('something.com', 'something.something');

$email = "test@domain.com";
list($name, $domain) = explode("@", $email);

if(in_array($name, $BlockedName) || in_array($domain, $BlockedDomain)) {
    //blocked
}

$BlockedNames = array('blah', 'bleh', 'something');
$BlockedDomains = array('something.com', 'something.something');

$email = "test@domain.com";
list($name, $domain) = explode("@", $email);

if(in_array($name, $BlockedName) || in_array($domain, $BlockedDomain)) {
    //blocked
}

 

 

lol heya corbin and thanks for the reply, could you explain how that works and where I would exactly place that in the script

 

 

Regards

[corbin]

No offense man, but that's very, very simple.  If you don't know how that works, just look up each function in the PHP manual and look at how it's being used.  The code block would be used in the validation process.

[NSW42]

ah na no offence taken, I can see how it works, but just cant see where to place it in the script is all, I started all this from scratch and im still learning as I go along.

[NSW42]

ok ive tried it right thru out the script with a test for blocking hotmail and it doesnt seem to block anything, just inserts to valids as usual, maybe im placing it wrong but did try a few diff ways, any suggestions.

if(in_array($name, $BlockedName) || in_array($domain, $BlockedDomain)) {

 

 

Should've been

 

if(in_array($name, $BlockedNames) || in_array($domain, $BlockedDomains)) {

 

 

My bad x.x.

[NSW42]

sorry but still no go  ???

[corbin]

if($_POST) {
$email = (isset($_POST['email'])) ? $_POST['email'] : '';
$BlockedNames = array('blah', 'bleh', 'something');
$BlockedDomains = array('something.com', 'something.something');

@list($name, $domain) = explode("@", $email);

if(in_array($name, $BlockedNames) || in_array($domain, $BlockedDomains)) {
	echo 'Blocked';
}
}

echo <<<H
<form action="" method="POST">
<input type="text" name="email" /><br />
<input type="submit" value="Go" />
</form>

H;
