Making Link Pop up in Iframe?

[Hwona]

Hello everyone, I've been trying to get the links of daycare pets to pop up in an iframe on the page when clicked, but I can't seem to find a way to link the php link to a target and when I try to use a html like and replace the id with a variable, the page pops up blank.
Here's the code for the daycare function(v.1.3.3):

PHP Code:

    public function daycare(){
        $mysidia = Registry::get("mysidia");
        $document = $mysidia->frame->getDocument();
        $document->setTitle($mysidia->lang->daycare_title);
        $document->addLangvar($mysidia->lang->daycare, TRUE);
        
        try{
            $daycare = new Daycare;
            $adopts = $daycare->getAdopts();
        }
        catch(DaycareException $dae){
            $message = $dae->getmessage();
            $document->addLangvar($mysidia->lang->{$message});
            return;
        }
        
        $daycareTable = new Table("daycare", "", FALSE);
        $daycareTable->setBordered(FALSE);
        $total = $daycare->getTotalAdopts();
        $index = 0;

        for($row = 0; $row < $daycare->getTotalRows(); $row++){
            $daycareRow = new TRow("row{$row}");
            for($column = 0; $column < $daycare->getTotalColumns(); $column++){
                $adopt = new OwnedAdoptable($adopts[$index]);
             $image = new Link("levelup/click/{$adopt->getAdoptID()}", $adopt->getImage("gui"), TRUE);
                $stats = new Comment($daycare->getStats($adopt));
                $daycareCell = new TCell(new ArrayObject(array($image)), "cell{$index}");
                $message1 = "<iframe name='iframe1' src='levelup/click/{$adopt->getAdoptID()}'></iframe>";
                $daycareCell->setAlign(new Align("center", "center"));
                $daycareRow->add($daycareCell);
                $index++;
                if($index == $total) break;
            }
            $daycareTable->add($daycareRow);            
        }
        
        $document->add($daycareTable);
        $document->addLangvar($message1);
        if($pagination = $daycare->getPagination()) $document->addLangvar($pagination->showPage());
    }
} 


Thanks! :D
