home 当我klik tambah pesan时，显示要插入orders_food的模式

modal view

evry coloumn有按钮 tambah pesanan （添加订单），如何从该coloumn中获取ID以插入到我的orders_foods中？

您可以像这样获取ID（这是html或twig模板 tableEntries.twig ：

<html>
<head>Get ID</head>
<body>
  <table>
        <thead>
          <tr>
              <td>column id</td>
              <td>column name</td>
              <td>column description</td>
              <td>column note</td>
          </tr>
        </thead>
        {% for someAlias in dataExample %} <!-- dataExample is an array in the php file -->
        <tbody>
            <tr>
<!-- *columnID*, *columnName*, etc. are 
the real mysql columns, while **someAlias** 
is just a random name for this for-loop. 
**dataExample** is the array which contains 
all the values of the corresponding columns -->
                <td>{{ someAlias.columnID }}</td>
                <td>{{ someAlias.columnName }}</td>
                <td>{{ someAlias.columnDescription }}</td>
                <td>{{ someAlias.columnNote }}</td>
            </tr>
        <td>
    <!-- The php script parses the mysql database 
and saves the id and all other values in an array. 
The php templating engine Twig uses this file as 
its template (frontend). 
If the Send-Button is pressed, the id will be 
saved inside $_POST["SecretIdUsedForIfSendButtonIsPressed"]; 
and can be used to add, edit or delete table entries (rows) 
from there. -->
         <form method="POST" action="addTableEntries.php">
          <input type="hidden" name="SecretIdUsedForIfSendButtonIsPressed" value="{{ SecretIdParsedFromTheMySqlDatabase }}">
          <input type="submit" value="tambah pesanan">
        </form>
       </tbody>
        {% endfor %}
    </table>
</body>
</html>

这是php脚本 tableEntries.php ：

<?php
/* Lists all column entries inside your mysql table(s)
 * Author: timunix
 * Date: 10.07.2018
*/
require_once 'vendor/autoload.php'; // you don't need to change the path, just leave it like that, twig will do the job for you
require_once "utils/Database.class.php"; // include database configuration

// init twig
$loader = new Twig_Loader_Filesystem('template/'); /*no path adaptation needed, just leave it like that, twig will "know" where your twig/html templates are*/

$twig = new Twig_Environment($loader, array(
    "debug" => "true",
));
include "utils/injector.php";

$twig->addExtension(new Twig_Extension_Debug());

/* ------- */

DatabaseLink::getInstance()->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

// fetch data from database *(simple way, not entirely safe, though!)*
$stmt = DatabaseLink::getInstance()->query("SELECT * FROM tbl_columns WHERE columnID > 0");
$columnData = $stmt->fetchAll();

//template values
$templateName = "tableEntries.twig";
$data = array(
    "dataExample" => $columnData,
);

//display
echo $twig->render($templateName, $data);

如果有任何问题，请问我。
