PHP 动态 HTML 问题

Question

我有一段用 POST 形式包装的 PHP/HTML。如何仅将单击删除按钮所在行的 ID 传回服务器？

        <table>
            <tr>
                <th>File Path</th>
                <th>Expiration</th>
            </tr>
            <?php
                $result = mysql_query ($list_query);
                $row_count = mysql_numrows ($result);

                for ($i = 0; $i < $row_count; $i++) {
                    $id = mysql_result ($result, $i, "id");
                    $path = mysql_result ($result, $i, "path");
                    $expiration = mysql_result ($result, $i, "expires");
            ?>
                    <tr>
                        <td width="60%">
                            <?php echo $path; ?>
                        </td>
                        <td>
                            <?php echo $expiration; ?>
                        </td>
                        <td>
                            <input type="submit" value="Delete Expiration" />
                        </td>
                    </tr>
            <?php
                }
            ?>
        </table>

在表单中使用隐藏字段。

<input type="hidden" name="id" value="<?php echo $id ?>">

您还应该为每个新行开始一个新表单。

 for ($i = 0; $i < $row_count; $i++) {
                    $id = mysql_result ($result, $i, "id");
                    $path = mysql_result ($result, $i, "path");
                    $expiration = mysql_result ($result, $i, "expires");
            ?>
                    <tr>
                        <td width="60%">
                            <?php echo $path; ?>
                        </td>
                        <td>
                            <?php echo $expiration; ?>
                        </td>
                        <td>
                         <form method="POST" action="?">
                           <input type="hidden" name="id" value="<?php echo $id ?>">
                           <input type="submit" value="Delete Expiration" />
                         </form>
                        </td>
                    </tr>
            <?php
                }
            ?>
