我有一个php变量"echo $ id".现在，我想使用$ _POST方法发布变量.我只想知道如何对变量执行此操作，因为$ _POST [$ id]不起作用?

I have a php variable "echo $id". Now I want to use the $_POST method to post the variable. I just want to know how to do this for a variable because $_POST[$id] does not work?

推荐答案

使用$ _POST方法，您必须将其发布到某个东西.

With the method $_POST you must be posting to something.

我对您的建议是创建一个表单，然后将该表单转到您要发布到的文件:

My suggestion to you is to create a form, then have the form going to the file you wish to post to:

是这样的:

echo '<form action = "fileToPostTo.php" method = "post"> <input type = "text" hidden value = "'.$id.'" /> </form>';

然后在通过jquery或javascript加载文档时提交表单.

And then submit the form when the document loads through jquery or javascript.
