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
Sanj

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 itinclude('./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($v); } // forward to signup.phplist($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

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); 
}

Regards

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