preventing sign ups

[sanj]

hi,
When someone has placed an order and is added to my back end list, I don't want them to be able to signup to my other lists. How do I do that?

Thanks

Hi SanJ,

The best way at this time is with an intermediary script, ie:

Code: [Select]

<?php
// example signup2.php
// place in ListMail folder and point all signup forms to it
include('./config.php');
include('./admin.php');

// dont allow if on this list
$back_list = 1;

list($test)=@mysql_fetch_row(mysql_query("select id from lm_users where list = '$back_list' and email like '".addslashes($email)."';"));
if($test){
 echo "Sorry you may not subscribe...<br>";
 exit;
}

// build vars 
$vars=array(); 
foreach($_POST as $k=>$v){
 $vars[]=$k.'='.urlencode($v); 
} 

// forward to signup.php
list($lmp)=@mysql_fetch_row(mysql_query("select listmailpath from lm_config"));
header('Location: '.$lmp.'signup.php?'.implode('&',$vars));
?>
Please let me know if you need more help

Regards

hi Dean,
Tried the code. Doesn't work. Check out this page

SanJ,

I had access to your server through some previous technical work.  I found and fixed the problem on both your site and in the first code example above.

This:

Code: [Select]

// build vars
$vars=array();
while(list($k,$v)=each($_POST)){
 $vars[]=$k.'='.urlencode($v);
}

Needed to be this:

Code: [Select]

// build vars
$vars=array();
foreach($_POST as $k=>$v){
 $vars[]=$k.'='.urlencode($v);
}

Please try again - I thought I had removed that debug output but apparently I did not... I have done it now.
