Question

我正在创建座位预订系统。在我的系统中，公交车所包含座位的代码检查编号，然后将其传递到 for循环中。用户选择 2名乘客时，这意味着将预订两个座位。如何根据所选的乘客数量验证 for循环中的复选框。

使用GUI进行更多说明。

主页上的2表示选择的乘客人数。

当您进入值传递到的第二页时，您会看到 2位成人作为选定的乘客数量。当您点击提交按钮时，它不会根据所选乘客的数量来验证该复选框。如果我应该将必需放在复选框中，则它会验证整个复选框，因为它处于循环

$_SESSION['seat_no']是公交车包含的座位数。假设有一个要预订所选座位的用户两个乘客，这意味着预订了两个座位，我如何根据所选座位数来验证复选框？

这是我的代码：

<?php
    for ($i = 1; $i <= $_SESSION['seat_no']; $i++) {

        if(in_array($i,$mseat)){
            echo "<div class='checkbox_wrapper_pick'>        
                    <label>".$i."</label>
                </div>";
        }else{

            echo "<div class='checkbox_wrapper'>
                    <input type='checkbox' value=".$i." name='seat_book[]' />
                    <label>".$i."</label>
                  </div>";
        }
    }
?>
