我想测试我的按钮是否可以从日期的文本框中获取当前值？我得到了提交按钮的值，但找不到任何获取按钮名称的代码。那么我应该怎么称呼我能够查看该值？

If you'd like to get the value of 'oprf' above, then:
如果您想获得上面 'oprf' 的值，则：
$value = $_POST['obrf'];

Add type property with submit type="submit"to button tag this will submit the form then receive the form inputs value in php script with super global variable $_POST['input name']or $_GET[]wdepends on from action property value by default GET.
添加带有提交type="submit"到按钮标签的type 属性，这将提交表单，然后在 php 脚本中使用超级全局变量$_POST['input name']或$_GET[]wdepends接收表单输入值，默认情况下来自 action 属性值 GET。

You can do:
你可以做：
if ($_POST['oprf'] == '' || $_POST['oprf'] == NULL) {
//this checks to see if there has been a value that was sent with the
//form
}
I usually use isset for cookies.
我通常将isset用于cookie。

I don't think this works consitently in all browsers. Better to work with a customized nameattribute.
我不认为这在所有浏览器中都有效。最好使用自定义name属性。
