从非 codeigniter 项目获取会话数据 codeigniter

Question

我通过单击按钮发送了用户 ID

<form action="https://www.mysite.co.uk/some/index.php" method="POST">
    <input type="hidden" name="userid" value="ZUpmenVaN0ZVTTBmejNGZGNwZGFha1NmR0tuSjdaT3VYdjV5cTF4WGtISzRvK0ptOC9vZmQyc3J3T3cwTmplbWZ3alhod0xMYUhlQ2xLSng4WWI4ZEE9PQ2">
    <input type="submit" value="Go" style="font-size:14px; padding:20px;">
</form>

然后我获取用户 ID 并在普通 php 页面中使用它（outsidecodeigniter）

www.mysite.co.uk/some/index.php

<?php 
session_start(); 

  <?php
    if (isset($_POST['userid'])) {
        $_SESSION['userid'] = $_POST['userid'];
        $userid = $_SESSION['userid'];
    }
    if (isset($_SESSION['userid'])) {
        echo "You are logged in and have access to these tests.";?>

code here

    <?php
    } else {
        header ('location: ../index.htm');
    }
    ?>

我现在需要在控制器中使用用户 ID，该控制器将数据发送到代码点火器中的数据库

ci 控制器

 private function getResults()
    {
        $this->load->library('session');
        $this->session->set_userdata('user_id', $_POST['userid']);
        $userID = $this->session->userdata('user_id');

        $score = $this->actions->getSentEmailCount();
        $percentilescore = $percentile = $this->actions->getPercentile($score);
        $testID = '134';

        {
            $data['emailcount'] = $score = $this->actions->getEmailCount();
            $data['sentEmailCount'] = $score = $this->actions->getSentEmailCount();
            $data['score'] = $score = $this->actions->getScore();
            $data['percentile'] = $percentile = $this->actions->getPercentile($score);
            $data['timespent'] = $this->input->get('time');
        };

        $adddata = array(
            'uniID' => '5',
            'testName' => 'Abintegro E-Tray test',
            'testID' => $testID,
            'total' => '20',
            'useInPercentile' => '1',
            'correct' => $score = $this->actions->getScore(),
            'percent' => $score = $this->actions->getScore(),
            'percentile' => $percentilescore,
            'dateTaken' => date('Y-m-d H:i:s'),
            'timeSpent' => $this->input->get('time'),
            'userID' => $userID
        );

        $this->actions->add_record($adddata);
        return $this->load->view('client/results', $data);
    }

我收到一个错误

消息：未定义的索引：用户 ID

有人能看出我为什么会变成 null 吗？

首先，您必须使用 codeigniter 库启动会话 只需致电：

$this->load->library('session');

然后设置你的会话：

$this->session->set_userdata('user_id', $_POST['userid']);

然后在你的函数中访问会话变量，

private function getResults()
    {
        $score = $this->actions->getSentEmailCount();
        $userID = $this->session->userdata('user_id');
        $percentilescore = $percentile = $this->actions->getPercentile($score);
        $testID = '134';

        $adddata = array(
            'uniID' =>  $userID,
            'testName' => 'Abintegro E-Tray test',
            'testID' => $testID,
            'total' => '20',
            'useInPercentile' => '1',
            'correct' => $score = $this->actions->getScore(),
            'percent' => $score = $this->actions->getScore(),
            'percentile' => $percentilescore,
            'dateTaken' => date('Y-m-d H:i:s'),
            'timeSpent' => $this->input->get('time'),
            'userID' => $userID
        );
$this->actions->add_record($adddata);
        return $this->load->view('client/results', $data);
}

当您在自定义 PHP 中设置会话时，您无法从 CI 中检索它。您必须从自定义 PHP 中检索它。 喜欢::

session_start();
$userID = $_SESSION['userid'];
