PHP Output (PDO & CRUD) - php

Question

I need help with my PHP script.
I have 3 Tables in my Database (its German so sorry if you dont understand ^^):
-firma (in english company)
-produkt (in english product)
-firmaprodukt (in english companyproduct)
If I click on a company, the product image should be output (from the "Produkt" database) and the appropriate URL (from the "firmaprodukt").
So far I've managed that when you click on a company, the ID is displayed (example: "localhost/TESTING//index?1=") but I'm struggling with the output.
That's my index.php script for the output:
<div class="col-xl-6">
<div id="login_content">
<div class="scrollP">
<?php
$fpresults = $fpCrud->getPicUrl($FirmenID);
?>
<div class="col-12 d-flex justify-content-center heading-div">
<h3> <?= $result['firmenname']?> </h3>
</div>
<table border="0">
<tbody>
<?php
foreach ($fpresults as $fpresult){
?>
<tr>
<div class="box customer-box" data-parent="#login_card" id="project_reg_box">
<img src="dashboard/TESTING/<?= $fpresult['ProduktLogo']?>" height="100%" >
</div>
</tr>
<?php
}
?>
</tbody>
</table>
</div>
</div>
</div>
And that's in my crud.php:
public function getPicUrl($FirmenID) {
$stmt = $this->conn->query(
"SELECT fp.FirmenID, f.firmenname, p.ProduktLogo, fp.url
FROM firma f
JOIN firmaprodukt fp ON fp.FirmenID = f.FirmenID
JOIN produkt p ON fp.ProduktID = p.ProduktID
WHERE fp.FirmenID = :FirmenID");
$stmt->execute(array(':FirmenID' => $FirmenID));
$data = $stmt->fetch();
return $data;
}
In my formprocess.php I don't have anything for that.

My solution:
index.php
<?php
if (isset($_GET['firmaprodukte'])) {
$FirmenID = (int) $_GET['firmaprodukte'];
$firmaprodukte = $fpCrud->getPicUrl($_GET['firmaprodukte']);
$firmenresults = $firmaCrud->getFirma($_GET['firmaprodukte']);
?>
<div class="col-xl-6">
<div class="scrollP">
<div id="login_content">
<div id="login_card" class="container">
<?php
$fpresults = $fpCrud->getPicUrl($FirmenID);
?>
<div class="col-12 d-flex justify-content-center heading-div">
<h3> <?= $firmenresults['firmenname']?> </h3>
</div>
<table border="0">
<tbody>
<?php
foreach ($fpresults as $fpresult){
?>
<tr>
<div class="box customer-box" data-parent="#login_card" id="project_reg_box">
<img src="dashboard/TESTING/<?= $fpresult['ProduktLogo']?>" height="80vh" max-width="200vh">
</div>
</tr>
<?php } ?>
</tbody>
</table>
</div>
</div>
</div>
</div>
<?php } ?>
Crud.php
public function getPicUrl($FirmenID) {
$stmt = $this->conn->prepare("SELECT fp.FirmenID, f.firmenname, p.ProduktLogo, fp.url FROM firma f JOIN firmaprodukt fp ON fp.FirmenID = f.FirmenID JOIN produkt p ON fp.ProduktID = p.ProduktID WHERE fp.FirmenID = :FirmenID");
$stmt->execute(array(':FirmenID' => $FirmenID));
$data = $stmt->fetchAll();
return $data;
}
formprocess.php
if(isset($_POST['firmaprodukte'])) {
$FirmenID = $_POST['FirmenID'];
if($crud->getPicUrl($FirmenID)) {
header('location: FirmaProdukt.php');
exit;
} else{
header('location: FirmaProdukt.php');
exit;
}
}
