Question

我正在尝试创建一个网页，其中一张桌子列出了整整一个月的一顿饭。我希望能够在每行开头（1行 - 一天）中使用单选按钮来选择下一个用餐。这背后的原因是我有另一个网页显示“下一餐：XXX”，其中XXX从数据库中读取（类似“where nextmeal = 1”）。基本上我想要的是当我激活我的一个单选按钮时，此行中的一餐应该在数据库条目中得到nextmeal = 1。 数据库表包含以下 columns = date，meat，veggie，nextmeal 我尝试了一些关于如何向服务器发送活动单选按钮值的建议，但是我无法将正确的日期粘贴到服务器上以进行正确的查询。

表格网页的源代码：

<?php
require_once 'db_config.inc.php';
require_once 'functionsgerichte.php';
$db = new mysqli($db_server,$db_user,$db_password,$db_database);
if(!empty($_GET['monat'])) {$monat = $_GET['monat'];} //define default_month
else $monat = 14;
if(!empty($_GET['jahr'])) {$activ_year = $_GET['jahr'];} //define  default_year
else $activ_year = 2010;
?>

编辑：在点击表单后，我还希望保持之前单击的单选按钮保持活动状态，将表单添加到源代码中。

Answer 1

这是答案......

将收音机类型名称视为收音机[]

示例"<input type='radio' id='radio_".$i."' name='radio[]' value='radio_".$i."' />;

“radio []”中存储的无线电值

在提交busson clcik上获取类似

的数组

$data = $_POST['radio'];
Print_r($data);

我希望它对你有帮助..

Answer 2

我已根据您的用户界面创建了HTML。

执行操作就像用户可以选择任何单选按钮并单击存储在数据库中的SAVE按钮单选按钮值。

在页面页面上加载先前的选择。
