Question

嗨，我从数据库中回显了多行。每行都有一个选择框，它会回显该字段中与该行相关的当前内容。

使用选择框，我可以选择其他选项。提交时没有任何反应，没有错误。它应该做的是更新这些字段。我从未尝试过更新多行，所以这对我来说是新的。

下面的第一个查询是我试图通过order_ref更新所有字段的更新

第二个查询只是回显查看所需的所有数据。

<?php
ini_set('display_errors', 1); ini_set('log_errors',1); error_reporting(E_ALL); mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
?>
    <form>
    <table class="tbl-qa">  
            <thead>
                 <tr>
                    <th class="table-header"><p>Action</p></th>
                    <th class="table-header"><p>Campaign</p></th>
                    <th class="table-header"><p>Title</p></th>
                    <th class="table-header" width="100px"><p>Order Reference</p></th>
                    <th class="table-header"><p>Last updated</p></th>
                  </tr>
            </thead>
            <tbody> 
    <?php
        require_once("../db/db_connection.php");
        if (isset($_POST['submit'])) {      
            $sql = $db->prepare("UPDATE articles SET order_ref=? WHERE id=?
            ");
            $order_ref = $_POST['order_ref'];

            $sql->bind_param("ii", $order_ref, $_GET["id"]);    
            if($sql->execute()) {
                $success_message = "Edited Successfully";
            } else {
                $error_message = "Problem in Editing Record";
            }
        }
        $sql = $db->prepare("SELECT * FROM articles WHERE campname=? ORDER BY order_ref ASC

    ");
        $sql->bind_param("s",$_GET["campname"]);            
        $sql->execute();
        $result = $sql->get_result();
    ?>

    <?php
                    if ($result->num_rows > 0) {        
                        while($row = $result->fetch_assoc()) {
                ?>  

                <tr>

                    </select>

                    <td class="table-row"><?php echo strftime("%b %d, %Y", strtotime($row["last_updated"])); ?></a></td>
                    <!-- action -->
                    </tr>
                <?php

                        }
                    }

                    else {
                        echo "No results";
                    }

                ?>
                                <tr class="table-row">
                    <td colspan="5"><input name="submit" type="submit" value="Update" class="submit"></td>
                </tr>
            </tbody>
        </table>

    </form>

我需要做什么才能为回显的每一行更新order_ref？

PHP在提交时更新多行
