Merhabalar, bir noktada kaldım 2 tablom var "projekatagori" ve "projeler" olarak ben https://codepen.io/alisinan/pen/xXaGXr buradaki galeri ile gruplu olarak yapmak istiyorum fakat sanırım bazı şeyleri çok karıştırdım bunu düzeltmeme yardımcı olacak varmı ?
Benim düzelttiğim kodlar;

<?php

$katsor=$db->prepare("SELECT * from projekatagori order by prokat_id DESC");
    $katsor->execute();
$katcek=$katsor->fetch(PDO::FETCH_ASSOC);

$sor=$db->prepare("SELECT * FROM projeler where prokat_id=:prokat_id");
$sor->execute(array(
  'prokat_id' => $katcek['prokat_id']
));

    while($cek=$sor->fetch(PDO::FETCH_ASSOC)) {
 ?>

<?php echo $katcek['resim'] ?>
      <div class="col-md-4">
        <div class="panel panel-default fixed-width center-block" data-toggle="modal" data-target="#project<?php echo $cek['pro_id']; ?>">
          <div class="panel-body">
            <a href="#">
              <img class="img-responsive center-block" src="uploads/katagori/<?php echo $katcek['resim']; ?>"  />
            </a>
          </div>
          <div class="panel-footer">
            <a href="#"><h3><?php echo $katcek['baslik']; ?></h3></a>
          </div>
        </div>
        <div class="modal fade" id="project<?php echo $cek['pro_id']; ?>">
