PHP:将POST转换为简单变量? [英] PHP: translate POST into simple variables?

问题描述

我知道这是完全错误的，我没有编写该应用程序，我只需要在开发新应用程序时使其运行即可.好像GoDaddy对我们的帐户进行了一些更新，所以现在有些事情不起作用了.我已经打开了寄存器全局变量，许多事情恢复了正常.现在，这不起作用...

I know this is totally wrong, I didn't write the app, I just have to make it work while I work on the new one. Seems like GoDaddy made some updates to our account so now there are some things that don't work. I already turned register globals on and a lot of things went back to normal. Now, this doesn't work...

有一个隐藏字段<input type="hidden" name="SUBMIT1" value="1" />

有一个检查该字段

if($SUBMIT1) {
  // this part never gets executed. 
}

我知道我可以通过执行此操作轻松解决它...

I know I can easily fix it by doing this instead...

if($_POST['SUBMIT1']) {
  // this part never gets executed. 
}

问题是，这是一个巨大的应用程序，要花很多时间才能在任何地方都可以做到这一点.有什么方法或设置可以打开，以便在提交表单时$_POST['WHATEVER']也可以用作$WHATEVER?

The problem is, this is a huge app and it's going to take a loooong time to do that everywhere. Is there a way or a setting I can turn on so that when a form is submitted $_POST['WHATEVER'] also works as $WHATEVER?

推荐答案

您可以使用 extract 以获得您描述的确切功能:

You can use extract to get the exact functionality you described:

extract($_POST);

请注意此处可能存在的安全问题:用户可以在$_POST中发送额外的数据，并覆盖"代码中现有变量的值.您可以将第二个参数传递给extract来防止出现这些问题:

Please note the possible safety issue here: a user could send extra data in $_POST and "overwrite" the values of existing variables in your code. You can pass a second parameter to extract to prevent these problems:

extract($_POST, EXTR_SKIP);

这将跳过提取$_POST数组中在当前作用域中已经具有匹配变量的任何字段.

This will skip extracting any fields in the $_POST array that already have matching variables in the current scope.
