not showing already clicked pets/pets owned by system on page

[Ittermat]

Im wondering how to make it so pets that are already clicked for the day or are owned by SYSTEM (As they're dead if they are on my site and cant be clicked further) I tried to edit the code in daycareclass- but not sure how to translate it to just a page..thats not a bigger bit of code.

For context im making a page thats like a pet park where people can go play with pets- and give them clicks.
However I dont want the ones already clicked/dead to appear.


this is what I have at the moment:

<?php

class petparkclickView extends View{

    public function index(){
        $mysidia = Registry::get("mysidia");
        $mysidia->db->update("users_profile", ["last_seen" => "Playing with pets at the park"], "uid = {$mysidia->user->uid}");
         $document = $this->document;
        $document->setTitle("<center>Pet Park</center>");
$document->add(new Comment("<br><center><h2>This is where you can find pets to play with! </h2><br> (It only shows 15 at a a time to save bandwidth)<br>", FALSE));

    $idsM = $mysidia->db->select("vote_voters", array("adoptableid"), "date='{$datetime}' and username='{$user->username}'")->fetchAll(PDO::FETCH_COLUMN);
        $adoptsIDs = new ArrayObject($idsM);

$document->add(new Comment("<div class='row'><h2>15 random playing pets!</h2>", FALSE));

if($owner != 'SYSTEM' ){
        $stat_rand5 = $mysidia->db->select("owned_adoptables", array("aid"), "1 ORDER BY RAND() DESC LIMIT 15");       
        while($aid = $stat_rand5->fetchColumn()){
            $adopt = new OwnedAdoptable($aid);   
            //take adoptable IDs that have been clicked by the user in today's date
    
            $document->add(new Comment("
                <div style='display: inline-table; text-align: center;'>
                <a href='levelup/click/{$adopt->getAdoptID()}'><img src='{$adopt->getImage()}'></a></br>
                  <a href='levelup/click/{$adopt->getAdoptID()}'><br><b>{$adopt->getName()}</b></a><br> the <small><b>LVL.</b> {$adopt->getCurrentLevel()}</small><br> {$adopt->getType()}</div>
              ", FALSE));
        }
        $document->add(new Comment("</div>", FALSE));


}
            }}
            ?>
