Hi guys. I have very strange problem that i cant managed fo few hours. This is realy hard to understand for me. I work on website and i want it to have banners in few places. In admin i created structure: Banners > Banner Group > Banner 1, Banner2, Banner 3 etc. I want this banners to be loaded one by one rather than randomly. I created function that print baner and save its id to session variable like this: function renderBannerBox($banner_group = false) { //takes banner group name as argument $out = ''; if ($banner_group) { $bgroup_url = '/banners/' . $banner_group . '/'; $bgroup = wire(pages)->get($bgroup_url); if ($bgroup->id) { $bgroup_id = $bgroup->id; //for every banner group create separate session variable to store displayed banners $session_name = $bgroup->name . '_array'; //get session variable with array of ids of displayed banners $displayed_banners = wire(session)->$session_name; $selector = "id!="; $selector .= substr($displayed_banners, 0, -1); $selector .= ", template=banner, parent=$bgroup_id"; $banners = wire(pages)->find("template=banner, parent=$bgroup_id"); $banner = $banners->get($selector); //if no banner (first view or all banners from group displayed) get random banner and if (! $banner->id) { $displayed_banners = ''; // clear $displayed banners variable $banner = $banners->findRandom(1)->first; //get random banner } //add current banner id to variable $displayed_banners .= $banner->id . '|'; // save variable to $session wire(session)->$session_name = $displayed_banners; // code for html formating } } Strange thing is that for every page refresh different number of banners ids are saved to my $session variable. One time is 1 id, second time 2 ids and so on. You can see it here: http://demo.webego.pl/ginfo/ - above every banner i print current value of $session variable. I tested it also in my main template file with independent test variable - it works the same way. It looks like page is sometimes 'double loaded'. Please let me know if you have any idea what is going on.
