PHP 输出（PDO 和 CRUD）

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">
                            <a href="<?= $fpresult['url']?>"> <img src="dashboard/TESTING/<?= $fpresult['ProduktLogo']?>" height="100%" > </a>
                        </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">

                                                 <?php  } ?>
                                             </tbody>
                                         </table>
