Question

我有一个复选框和一个选择下拉菜单，用于选择一个晚餐课程，该课程将循环显示4个房间。当我选择多个房间时，会得到以下输出：

大象室

三道菜

两道菜

和

狮子室

三道菜

两道菜

但是我想要这个输出：

如果我为大象房选择了两道菜，我会这样：

大象室

两道菜

和

如果我为狮子房选择三道菜，我想要这样做：

狮子室

三道菜

我已经尝试通过与众不同的方式以多种方式修改foreach循环。我还不是循环专家，而且还没有循环专家。

HTML

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

<form name="book-room-form" action="" id="contactForm" method="post">

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

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

    <button name="submit-request" type="submit" class="btn btn-primary">Submit</button>

</form>

<?php endwhile; // end of the loop. ?>

PHP

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;

                if ($dinneroption) {
                    foreach ($dinnerSelect as $dinn){
                        if($dinn >= 200){
                            echo 'three course <br/>';
                        }
                        elseif($dinn == 120) {
                            echo 'two course <br/>';
                        }
                    }
                }
            }
        }
    }
}

有什么办法可以解决这个问题吗？

似乎很奇怪，您将循环表单，并且在每个表单中仅包含单个文本输入和单个选择菜单-似乎更有意义的是，您将拥有单个表单然后在输入元素周围循环，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>

其中的PHP部分无法由我轻松测试，因此可能存在问题，但是您可以对其进行一些修改

if( $_SERVER['REQUEST_METHOD']=='POST' && isset( $_POST['submit-request'], $_POST['room-selected'], $_POST['people-select'], $_POST['dinner-select'] ) ){

    $room_selected = filter_input( INPUT_POST, 'room-selected', FILTER_SANITIZE_STRING );
    $numPeople = filter_input( INPUT_POST, 'people-select', FILTER_SANITIZE_NUMBER_INT );
    $dinnerSelect = filter_input( INPUT_POST, 'dinner-select', FILTER_SANITIZE_NUMBER_INT );

    if( $room_selected & $numPeople & $dinnerSelect ){
        foreach( $room_selected as $room ){

            if( $room ){

                echo $room . '<br/>';

                foreach( $dinnerSelect as $value ){
                    switch( intval( $value ) ){
                        case 120:echo 'two course <br/>';break;
                        case 200:echo 'three course <br/>';break;
                    }
                }
            }
        }
    }
}
