        echo "<td><a href='product_detail.php?sendVar=".$product_id."' onclick='".$_SESSION['kuy'] = $product_id."'>".$product_title."</a></td>";
        echo "<td>".$product_name."</td>";
        echo "</tr>";
    }

Answer 1

onclick event works only with javascript in browser

In your code you rewrite kuy session for each item in the loop. When your page is rendered, you can find kuy with last product_id

If you want to set session with product_id , you should do it in your product_detail.php Here you can fetch product_id from $_GET['sendVar'] and set this value to $_SESSION['kuy']
