循环中的PHP POST select框未按正确顺序显示值

我有一个复选框和一个选择下拉列表来选择一个晚餐课程，循环显示4个房间。当我选择多个房间时，我会得到以下输出，例如：

大象房

三道菜

两道菜

和 狮子房

三道菜

两道菜

但我想要这个输出： 如果我为大象房选择了两道菜，我想要：

大象房

两道菜

和 如果我为Lion Room选择了三道菜，我想要：

狮子房

三道菜

我尝试过通过使用foreach循环，以多种方式修改foreach循环。我还不是循环方面的专家，循环中的循环

奇怪的是，您将循环表单，并且在每个表单中只包含一个文本输入和一个选择菜单-似乎更有意义的是，您将使用单个表单，然后循环输入元素，如下所示：

<!-- can leave the ID for the form as it is outside the loop -->
<form name="book-room-form" id="contactForm" method="post">

    <?php while ( have_posts() ) : the_post(); ?>

    <!--- to segregate the looped form elements -->
    <fieldset>

        <div>
            <label class="form-check-label selected-label" for="room-selected">Select</label>
            <!-- remove id attribute from input -->
            <input type="checkbox" class="form-check-input" name="room-selected[]" value="<?php $room_name; ?>">
        </div>

        <select name="dinner-select[]" required>
          <option value="0" selected>Select Dinner Course
          <option value="120">Two Course Dinner
          <option value="200">Three Course Dinner
        </select>

    </fieldset>

    <?php endwhile;?>

    <!-- a single "submit" button rather than however many were generated by the loop -->
    <button name="submit-request" type="submit" class="btn btn-primary">Submit</button>

</form>

您不能重复循环中的
id
属性~
id=“contactForm”
和
id=“contactForm”
。表单不需要id，所以可以删除它。@RamRaider感谢您指出，我只是在没有id的情况下尝试了它，但结果仍然是相同的，对问题没有影响，我同意。谢谢，但它给出了相同的输出，我对它进行了很多修改，并根据您给我的内容尝试了不同的方法。但是，switch语句不起作用，它返回一个空白输出，但当我在中插入原始if语句时，它就起作用了，只是两个晚餐课程仍在列表中。关于如何操作循环，您还有其他建议吗？
if(isset($_POST['submit-request']))
{

    $room_selected = $_POST['room-selected'];
    $numPeople = $_POST['people-select'];
    $dinnerSelect = $_POST['dinner-select'];

    $roomoption = isset($room_selected) ? $room_selected : false;
    if ($roomoption) {
        foreach ($room_selected as $room){
            if($room){
                echo $room . '<br/>';

                $dinneroption = isset($dinnerSelect) ? $dinnerSelect : false;
