in normal time, checkboxes return an on/off value.
在正常情况下，复选框返回一个开/关值。
you can verify it with this code:
您可以使用以下代码进行验证：
<form action method="POST">
<input type="checkbox" name="hello"/>
</form>

In your form tag, rather than
在您的表单标签中，而不是
name="booking.php"
use
用
action="booking.php"
And then, in booking.php use
然后，在booking.php中使用
$checkValue = $_POST['booking-check'];
Also, you'll need a submit button in there
此外，您还需要一个提交按钮
<input type='submit'>
