PHP：在页面中存储PHP变量以在POST中使用

Question

Currently I put a constant on my webpage using PHP which I then send, with Ajax, to my POST function. However, this leaves it susceptible to hacking (the user could change the variable with Firebug), so is there a way to store the variable in the PHP of the page and then access it later on, in the POST method (or is the GET variable of the page still available in the POST function, since that's where I get the variable from)?

Answer 1

I think what you have wanted is to store the post value to use it later.

Here you would need to use $_SESSION

You can do it like

session_start();

// Save variables into session

$_SESSION['thevalue'] = $_POST['value'];
