while statements, eval, and only one result showing :(
 
hey guys, i'm using the Template Hack, mucho props to whomever made that, it's a great hack!

however, i'm trying to make a raffle like hack with this, so far i'm not doign to bad :)

this would be my first attempt at a hack.

i have this in my code
PHP Code:
//check to see that $id is not set
if(!isset($id)) {
    $raffle = $DB_site->query("SELECT * FROM raffle_list WHERE status='current'");
        while($raffleql = $DB_site->fetch_array($raffle)) {
        
        $raftitle = $raffleql['title'];
        $rafid = $raffleql['id'];
         eval("\$ticketid = \"".logiciangettemplate('ticketid')."\";");
        }//end while
}//end $id is not set 
and then i have my template set to use $ticketid, which works great :)

but then the ticketid tempalte looks like this

PHP Code:
<a href="show.php?pg=raffle&id=$rafid">$raftitle</a> 
the $rafid and $raftitle work like a charm, however, if i have 2 raffles i want to show up it only shows one :(

how do you make the while statement work correctly? i know you can do it, since teh forumhome and forumdisplay does it :)

thanks alot ;)

yeah ive had this prob before, with a simple shout box i made, when i eval`d i could only get 1 result showing

After a quick look to your code, try to replace this:

PHP Code:
eval("\$ticketid = \"".logiciangettemplate('ticketid')."\";"); 
for this:

PHP Code:
eval("\$ticketid .= \"".logiciangettemplate('ticketid')."\";");

hmm ok i even tried it within my original raffle template and not using $ticketid and what not as seperate templates....


any help would be great here :) usually there will only be one raffle but there may be more then 1 sometimes :) thanks for your input

actually that would make sense .= so it takes more as needed :)

thanks!

No problem :)

Be uber-certain to either unset() or set to "" $ticketid first to avoid HTML injection.

Boofo 05-15-2003 02:16 PM
Would this be the same thing then?

$pollrun = "";
unset($pollrun);

even though the variable hasn't been declared yet?

filburt1 05-15-2003 02:24 PM
Either:
PHP Code:
unset($pollrun); // i like because it happens to free memory too 
or
PHP Code:
$pollrun = ""; 
works. Remember with vB2, register_globals is explicitly turned on which is the biggest security hole known to mankind.

Boofo 05-15-2003 02:26 PM
Which one would you have to use with register_globals turned off?
