登錄后如何將用戶重定向到當前頁面（Codeigniter）

Question

登錄后如何將用戶重定向到當前頁面？

用戶在這個網址閱讀新聞domain.com/article/news-18565一旦他點擊登錄按鈕，然后我怎么之前會得到CURRENTURL（） domain.com/login和用戶登錄后，應及時到domain.com/article/news-18565

Form.html

<form action="signin" method="post" accept-charset="utf-8">
        <div class="form-group">
            <label for="">Email:</label>
            <input type="text" name="email" value="" class="form-control form-control-lg">
        </div>

        <div class="form-group">
            <label for="">Password:</label>
            <input type="password" name="password" value="" class="form-control form-control-lg">
        </div>

        <div class="form-group">
            <input type="submit" name="submit" value="Sign in to your account" class="float-md-right btn btn-primary">
        </div>
    </form>

Controller.php

    function index(){

    $user_profile = 'user';
    $this->authModel->loggedin() == FALSE || redirect($user_profile);

    $rules = $this->authModel->rules;
    $this->form_validation->set_rules($rules);
    if($this->form_validation->run() == TRUE){
        if($this->authModel->login() == TRUE){
            redirect($user_profile);
        }else{
            $this->session->set_flashdata('error', 'That email/password combination does not exist');
            redirect('signin');
        }
    }
 }

模型.php

    function login(){

    $user = $this->get_by(array(
            'email' => $this->input->post('email', TRUE),
            'password' => $this->hash($this->input->post('password'))
        ), TRUE);

    if(count($user)){
        $data = array(
            'name' => $user->name,
            'email' => $user->email,
            'username' => $user->username,
            'loggedin' => TRUE
        );
        $this->session->set_userdata($data);
        return TRUE;
    }

}

好，您需要使用HTTP_REFERER網址。 如您所說，http Referer URL將用戶重定向到上次訪問的URL

例如：成員單擊登錄按鈕后，正在該URL domain.com/article/news-18565上閱讀新聞，然后在進入domain.com/login之前以及在登錄后成員應該進入domain.com之后如何獲取currenturl（） / article / news-18565

為此，您需要檢查最后訪問的URL，請參見代碼示例。

$this->session->set_userdata($data);
if(!empty($_SERVER['HTTP_REFERER'])){
    redirect($_SERVER['HTTP_REFERER']);
} else {
   // add here the default url for example dashboard url
}

希望有任何問題讓我知道
