Loop within a loop
 
I am trying to display 2 screenshots for one file and 1 screenshot for another file but the second file takes on all 3 screenshots while the first file takes on its 1 screenshot which it should do.

Screenshot provide as to what it is doing.

Here is the code:
PHP Code:
$query = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "download WHERE catid = '" . $cid . "' LIMIT " . ($limitlower - 1) . ", $perpage");
$pagenav = construct_page_nav($pagenumber, $perpage, $filecount['filecount'], 'download.php?' . $vbulletin->session->vars['sessionurl'] . 'do=cat&catid='. $cid . '');
    while ($dl = $db->fetch_array($query))
        {
            $fid = $dl['file_id'];
            
            $moderated = $dl['moderated'];
            $version = $dl['version'];
            $name = $dl['name'];
            $title = $dl['title'];
            $size = $dl['size'];
            $description = $dl['description'];
            $username = $dl['username'];
            $userid = $dl['userid'];
            $ugpid = $dl['usergroupid'];
            $bytes = vbmksize($size);
            $fileview  = $ugpid;

            if (!empty($ugpid))
            {
            $ugpids = explode(',', $ugpid);
            }
            else
            {
            $ugpids = array('0');
            }
            $myids = '';
            if ($vbulletin->userinfo['membergroupids'] == '')
            {
            $myids = array($vbulletin->userinfo['usergroupid']);
            }
            else
            {
            $myids = explode(',',$vbulletin->userinfo['membergroupids']);
            }
            
            $showfile = 0;

            if (!empty($ugpid))
            {
            for ($i=0; $i<=20; $i++)
            {
            if (in_array($ugpids[$i], $myids))
            {
            $showfile = 1;
            }
            }
            }

            $screenshots = $vbulletin->db->query_read("SELECT * FROM download_screenshots WHERE file_id = '".$fid."' LIMIT 3");
            $screenshotcount = $vbulletin->db->num_rows($screenshots);
            while ($screenshota = $vbulletin->db->fetch_array($screenshots))
            {    
                        $sid = $screenshota['sid'];
                        $screenshot = $screenshota['sdata'];
                    eval('$screenshots_dis .= "' . fetch_template('bfc_download_screenshot_bit') . '";');
            }

            eval('$display_bit .= "' . fetch_template('bfc_download_bit') . '";');
            unset($sid);
        } 
I wanted to do a more accurate loop before displaying but for the life of me I can't figure out one that will work.

Perhaps you need to zap $screenshots_dis to '' before going into the loop otherwise it is already has content.

LOL what in the world are you talking about? I'm confused now.

PHP Code:
   $screenshots_dis = '';
        while ($screenshota = $vbulletin->db->fetch_array($screenshots)) 
            {     
                        $sid = $screenshota['sid']; 
                        $screenshot = $screenshota['sdata']; 
                    eval('$screenshots_dis .= "' . fetch_template('bfc_download_screenshot_bit') . '";'); 
            }

Oh duh, didn't realize that is what you meant, '' looks like quotes instead of ' '. Got it now, thanks alot.
