【问题描述】：
我正在尝试创建一个网页，其中的表格列出了整整一个月的一堆饭菜。我希望能够在每一行的开头（1 行 - 一天）使用 单选按钮 来选择下一餐是哪一餐。 这背后的原因是我有另一个网页将显示“下一顿饭：XXX”，其中 XXX 是从数据库中读取的（类似于“where nextmeal=1”）。 所以基本上我想要的是，当我激活我的一个单选按钮时，这一行中的餐点应该在数据库条目中获得 nextmeal=1。 数据库表有以下columns = date,meat,veggie,nextmeal 我尝试了一些关于如何将活动单选按钮值发送到服务器的建议，但我无法将正确的日期粘贴到服务器以执行正确的查询。
表格网页源代码：
<?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;
?>

然后点击表单的代码：
require_once 'db_config.inc.php';
require_once 'functionsgerichte.php';
$connection = mysql_connect($db_server,$db_user,$db_password);
mysql_select_db($db_database,$connection);
$LetzterTag = $_REQUEST['letztertag'];
$AlleTage = array();
$year= $_REQUEST['jahr'];
$month= $_REQUEST['monat'];
for($i=0; $i<$LetzterTag;$i++) {
//Erstellung von je einem Object je Tag
$ActiveDay[$i] = new NeuerTag;
array_push($AlleTage,$ActiveDay[$i]);
}
$i = 0 ;
for($i=1; $i<$LetzterTag;$i++) {
$time = $year.'-'.$month.'-'.$i;
if(date('l',strtotime($time)) == "Saturday" ||date('l',strtotime($time)) == "Sunday" || in_array(strtotime($time), $Freietage))
$ActiveDay[$i]->Feiertag = true;
if($ActiveDay[$i]->Begin == 0) {
$naechstesessen= $_REQUEST['naechstesessen'];
$fleischrequest='fleisch_'.$i ;
$fleisch= $_REQUEST[$fleischrequest];
$veggierequest='veggie_'.$i ;
$veggie= $_REQUEST[$veggierequest];
$connection=mysql_connect('oris', 'root', 'orhro');
mysql_select_db('anwesenheit',$connection);
if ($naechstesessen== "radio_1") {
$sql = "update gericht set naechstesessen='1'";
try {
$query = mysql_query($sql);
} catch (Exception $e) {
echo $e->getMessage();
}
$sql = "update gericht set naechstesessen='1' where Datum='".$time."'";
try {
$query = mysql_query($sql);
} catch (Exception $e) {
echo $e->getMessage();
}
}
$sql = "DELETE from gericht where Datum='".$time."'";
try {
$query = mysql_query($sql);
} catch (Exception $e) {
echo $e->getMessage();
}
$sql = "INSERT INTO gericht (Datum,Fleisch,Vegetarisch) VALUES ('".$time."','".$fleisch."','".$veggie."')";
try {
$query = mysql_query($sql);
} catch (Exception $e) {
echo $e->getMessage();
}
}
}
Header("Location: ".$_SERVER['HTTP_REFERER']."");
编辑：我还希望在单击表单、将表单添加到源代码后保持之前单击的单选按钮保持活动状态。
【问题讨论】：
-
存储用餐日期不是更简单吗？
-
您只需要一个数组来存储提交时选择的平均值
-
当然，但我仍然在努力为我想要存储的日期找到正确的行。我添加了一些内容以使我的问题更具体
-
@Shadow 你会如何储存食物？我仍然需要一种方法，以便以某种方式选择下一顿饭并在页面重新加载时保持选中状态，直到我在另一天选择另一顿饭。
