如何使用 PHP/MYSQL 从我的项目页面在我的项目详细信息页面中显示一个项目

Question

Okay So Here I'm trying to link a Item details page to a Item page, I have successfully done so however when I click on an item all the item details are showing up I would like to know how to Only Display one item on the item details page for the corresponding id. I know I'm missing some code (think its a GET or POST variable) to complete the link if anyone can help it will be much appreciated thanks alot

Heres my code

item.php

            <div class="rone">
            <?php
        $conn = new mysqli("xxx", "xxx", "xxx", "xxx");
        if ($conn->connect_error) {
            die("Connection Failed!" . $conn->connect_error);
        }
        ?>
            <?php
                $stmt = $conn->prepare('SELECT * FROM items');
                $stmt->execute();
                $result = $stmt->get_result();
                while ($row = $result->fetch_assoc()):
            ?>

            <div class="col-4">
                <a href="item-details.php?id=<?= $row['id'] ?>"><img src="<?= $row['itemimage'] ?>"></a>
                <h4"><?= $row['item_name'] ?></h4>
           </div>
           
            <?php endwhile; ?>                                                           
            </div>

item-details.php

            <div class="rone">
            <?php
        $conn = new mysqli("xxx", "xxx", "xxx", "xxx");
        if ($conn->connect_error) {
            die("Connection Failed!" . $conn->connect_error);
        }
        ?>
            <?php
                // UPDATE when this is done it does not work it gives the following error:: Uncaught Error: Call to a member function execute() on bool in C:\xampp\htdocs\assignment1\item-details.php:111 Stack trace: #0 {main} thrown in and the line 111 they referring to is this $stmt->execute(); ------ But if I do this //$id = $_GET['id'];
                //$stmt = $conn->prepare('SELECT * FROM items WHERE id = 1') the code will work just fine but it will only show item 1 regardless of which item I click. Hope this helps 👍

                $id = $_GET['id'];
                $stmt = $conn->prepare('SELECT * FROM items WHERE id = $id');
                $stmt->execute();
                $result = $stmt->get_result();
                while ($row = $result->fetch_assoc()):
            ?>
            <div class="col-2">
                <img src="<?= $row['itemimage'] ?>" width="100%" id="ItemImg">                
            <?php endwhile; ?>
            </div>
            <div class="col-2">
                <h1><?= $row['item_name'] ?></h1>
            </div>
    </div>

the names of my rows are: id , itemimage, item_name and in time to come I will add other attributes And the main table is items.

Answer 1

I see $id ' ' ); Remove one of that ' to {$id}');
