如何使用javascript设置会话变量并通过php代码获取

javascript php laravel session laravel-5

如何使用javascript设置会话变量并通过php代码获取,javascript,php,laravel,session,laravel-5,Javascript,Php,Laravel,Session,Laravel 5,我有如下javascript代码： <script type="text/javascript"> $('#editRole').on('show.bs.modal', function (e) { $roleID = $(e.relatedTarget).attr('data-id'); // Here I want to set this $roleID in session may be like this :

我有如下javascript代码：

<script type="text/javascript">

    $('#editRole').on('show.bs.modal', function (e) {  

        $roleID =  $(e.relatedTarget).attr('data-id');
        // Here I want to set this $roleID in session may be like this :
        Session['roleID'] = $roleID;                      
    });    

</script>

<?php $roleID = Session::get('roleID'); //do something ....  ?>


$（'#editRole'）.on（'show.bs.modal'，函数（e）{
$roleID=$（e.relatedTarget）.attr（'data-id'）；
//在这里，我想设置会话中的$roleID可能如下所示：
会话['roleID']=$roleID；
});

然后我想在另一个地方使用php代码获取$roleID，可能是这样的：

<script type="text/javascript">

    $('#editRole').on('show.bs.modal', function (e) {  

        $roleID =  $(e.relatedTarget).attr('data-id');
        // Here I want to set this $roleID in session may be like this :
        Session['roleID'] = $roleID;                      
    });    

</script>

<?php $roleID = Session::get('roleID'); //do something ....  ?>

谢谢

您不能直接从JS设置服务器会话变量

要做到这一点，您可以对传递要设置的值的PHP脚本进行AJAX调用，并将其设置为服务器端：

$('#editRole').on('show.bs.modal', function (e) {  

    $roleID =  $(e.relatedTarget).attr('data-id');

    //ajax call 
    $.ajax({
         url: "set_session.php",
         data: { role: $roleID }
    });                             
});

set_session.php

//preliminary code

Session::put('roleID', $request->input('role') );

上述答案和其他资源一起帮助我制作了类似于“在laravel中使用AJAX设置会话”的示例

我发布了一个简单的例子，其他用户可能会觉得这很有帮助

View-ajax\u session.blade.php

//preliminary code

Session::put('roleID', $request->input('role') );

    \Session::put('uname', $request->uname);
    echo "session created";
}
public function getsession()
{
    dd(\Session::get('uname'));
}

您可以通过运行

localhost:8000/session\u form

来检查这一点。您还可以通过

localhost:8000/allsession

单独检查会话

希望这有帮助

您不应该也不能从客户端设置PHP会话变量。您必须向服务器发送一些内容，以便服务器进行设置，但您需要小心，以免暴露整个超全局。仅设置会话变量需要ajax调用？是否可以使用laravel直接在javascript代码中设置会话？
