I know the title is pretty vague but I am hoping someone can help me out here.
So the way the friends system works is it adds a user's id under the friend part in the database, but because users can have multiple friends it shows like "1, 16, 33" (for example). Clearly the comma is a separator, but I do not understand
how new entries are added in that format or
how the script knows to read each individual entry and use that information?
What I am trying to do is set up a system to record which users have used each promocode. So a user uses a promocode and it adds their ID to the list of those who've used it. Then I can add a setting option so that the admin can choose to make the promocode only redeemable once per user.
I can also eventually use it to set up a more stream-lined quest system than what I am currently using.
I found this chunk in class_friend.php which I think is relevant:
PHP Code:
public function append($uid){
$mysidia = Registry::get("mysidia");
$this->getfriendlist();
$friendsarray = $this->friendlist->getids();
if(!$this->isfriend) $friendsarray[] = $uid;
sort($friendsarray);
$friends = (count($friendsarray) == 1)?$uid:implode(",", $friendsarray);
$mysidia->db->update("users", array("friends" => $friends), "username='{$this->user->username}'");
}
But I am having a hard time figuring this out
Here's what I've added to class_promocode.php so far;
PHP Code:
private function checkredeem() {
//This will check to see which users have already redeemed this code.
$mysidia = Registry::get("mysidia");
$redeemed = $mysidia->db->select("promocodes", array("redeemed"), "pid='{$this->pid}'")->fetchColumn();
$redeem = {$mysidia->user->uid};
if(empty($this->redeemable)) return TRUE;
else{
if($redeemed){throw new AlreadyRedeemedException($mysidia->lang->redeemed);}
//Need to work on this part still...need to make it so that when they redeem it, they're ID is added to the list so they can't redeem it again
else {$mysidia->db->update("promocodes", array("redeemed" => $redeem), "pid='{$this->pid}'");}
return TRUE;
}
}
(I have lang_promo, admincp/promo, and admincp/view/promoview all ready to go, as soon as I get this figured out I'll release it as an actual mod)
But this is all I've got and right now it's pretty useless until I figure out how to properly add uids to the database.
If someone could help me I would really, really appreciate it <3
