从Jquery获取PHP $ _SESSION变量？ [英] Get a PHP $_SESSION variable from Jquery?

问题描述

我还不是JSON / AJAX大师，所以我不知道怎么做。

I'm not yet a JSON/AJAX master so I don't know how to do this.

我需要一个$ _SESSION ['name'] PHP变量与我的jQuery东西一起工作，我不知道如何访问它...考虑：

I need a $_SESSION['name'] PHP variable to work with in my jQuery stuff and I don't know how to access it... consider:

// the 'who is typing' shindig
    $.ajax(
    {
        url: "whos_typing.html",
        cache: false,
        success: function(whos)
        {   
                // here I need to access $_SESSION['name'] and do stuff with it

            $("#soandso").html(whos); //Insert who's typing into the #soandso       
        }
        });

推荐答案

你需要注射它，像这样的东西：

You'll need to inject it, something like this:

var sessName = '<?php echo $_SESSION['name']?>';

包含此脚本的文件必须由php解释器执行（即.php文件）

The file containing this script must be executed by the php interpreter (i.e. a .php file)

编辑：承认Radu的观点，对未经过抽样的数据执行会更安全：

Conceding to Radu's point, it would be safer execute for unsanitized data:

var sessName = <?php echo json_encode($_SESSION['name']) ?>;
