Question

我正在尝试在管理面板上显示所有菜单。我正在使用foreach循环来显示在数据库中输入的所有菜单。现在我想从菜单的foreach循环中的另一个表格中显示带有foreach循环的菜肴。

下面你可以找到我的foreach循环。

如何在div'panel-body'中添加另一个foreach循环，从$ menu ['ID']获取数据每当我尝试这样做时，我都会收到未捕获错误：调用数组中的成员函数get_menu_items（）如何在数组上调用成员函数？

 <?php foreach($menus as $menu): ?>
      <div class="panel panel-default">
           <div class="panel-heading">
                <h4 class="panel-title">
                     <a data-toggle="collapse" data-parent="#accordion-test" href="#<?php echo $menu['ID'] ?>" class="collapsed">
                          <?php echo $menu['title'] ?>
                     </a>
                </h4>
           </div>
           <div id="<?php echo $menu['ID'] ?>" class="panel-collapse collapse">
                <div class="panel-body">
                     <a href="deletemenu.php?id=<?php echo $menu['ID'] ?>">
                          <button type="button" class="btn btn-danger waves-effect waves-light w-xs m-b-5 pull-right" >Verwijder</button>
                     </a>
                     <a href="editmenu.php?id=<?php echo $menu['ID'] ?>">
                          <button type="button" class="btn btn-info waves-effect waves-light w-xs m-b-5 pull-right" style="margin-right: 5px;">Bewerken</button>
                     </a>
                </div>
           </div>
      </div>
 <?php endforeach; ?>


public function get_menu_items($id)
{
  try
  {
      $stmt = $this->db->prepare("SELECT * FROM menu_items WHERE menu_id=:menu_id");
      $stmt->execute(array(':menu_id' => $id));
      $result = $stmt->fetch(PDO::FETCH_ASSOC);
      return $result;
  }
  catch (PDOException $e)
  {
    echo $e->getMessage();
  }

}

public function get_menu()
{
  try
  {
    $stmt = $this->db->prepare("SELECT * FROM menu ORDER BY ID");
    $stmt->execute();
    return $stmt->fetchAll();
  }
  catch (PDOException $e)
  {
      echo $e->getMessage();
  }
}

foreach在数组上调用成员函数
