我一直在尝试将表单中包含的一些信息发布给自己。但我不明白为什么它不起作用。当我从 HTML 页面发布数据时它可以工作,但是当我将信息发布到自身时它不起作用。
继承人的代码:
$country = isset($_POST['country']) ? $_POST['country'] : 'Belize';
$number_of_guests = isset($_POST['number_of_guests']) ? $_POST['number_of_guests'] : 2;
$from = isset($_POST['price_range_from']) ? $_POST['price_range_from'] : 200;
$to = isset($_POST['price_range_to']) ? $_POST['price_range_to'] : 2000;
当我从 HTML 表单发布信息时,它工作正常,但在提交给自身时,所有变量都包含“on”的值。我不知道我遗漏了什么或未能正确实施。
这是 HTML 表单代码:
