如何在codeIgniter

Question

public function index() {

    if ($this->session->userdata('admin_login') == 1)
        redirect(base_url() . 'index.php?admin/admin_dashboard', 'refresh');

    if ($this->session->userdata('teacher_login') == 1)
        redirect(base_url() . 'index.php?teacher/teacher_dashboard', 'refresh');

    if ($this->session->userdata('student_login') == 1)
        redirect(base_url() . 'index.php?student/student_dashboard', 'refresh');

    if ($this->session->userdata('parent_login') == 1)
        redirect(base_url() . 'index.php?parents/parents_dashboard', 'refresh');

    $this->load->view('backend/login');
}

function ajax_login() {
    $response = array();
    $email = $_POST["email"];
    $password = sha1($_POST["password"]);

    $response['submitted_data'] = $_POST;
    $login_status = $this->validate_login($email, $password);
    $response['login_status'] = $login_status;
    if ($login_status == 'success') {
        $response['redirect_url'] = '';

    }
    echo json_encode($response);
}

我想通过$ response ['redirect_url'] =''传递index（）;如何通过？我已经尝试过通过创建路由来尝试，但无法正常工作。

index()是一个函数，根据您的代码，它可以重定向用户或显示页面。对于ajax响应而言，这都不是一件好事，因为重定向或视图只会在ajax请求中发生或呈现，而不会在用户的视口中呈现。

我假设您想在索引函数中添加逻辑，而不必重复太多。简单的解决方案是创建一个重定向功能。

创建一个助手并将其放入其中：

function group_redirect() {
    $ci = &get_instance();
    $ci->load->helper('url');

    if ($ci->session->userdata('admin_login') == 1)
        return base_url() . 'index.php?admin/admin_dashboard';

    if ($ci->session->userdata('teacher_login') == 1)
        return base_url() . 'index.php?teacher/teacher_dashboard';

    if ($ci->session->userdata('student_login') == 1)
        return base_url() . 'index.php?student/student_dashboard';

    if ($ci->session->userdata('parent_login') == 1)
        return base_url() . 'index.php?parents/parents_dashboard';

    return false;
}

然后剩下的就很简单了：

public function __construct() {
    $this->load->helper('name_of_helper_with_function');
}

public function index() {

    $redir = group_redirect();

    if ($redir) {
        redirect($redir);
    }

    $this->load->view('backend/login');
}

function ajax_login() {
    $response = array();
    $email = $_POST["email"];
    $password = sha1($_POST["password"]);

    $response['submitted_data'] = $_POST;
    $login_status = $this->validate_login($email, $password);
    $response['login_status'] = $login_status;
    if ($login_status == 'success') {
        $response['redirect_url'] = $redir;
    }
    echo json_encode($response);
}
