POST 由于未正确配置 htaccess 文件而无法正常工作

Question

我有一个结构良好且编码良好的表单，但是当我使用 post 将数据发送到我的控制器时..接收 post 数据的变量为空。我尝试向用户发送警报以查看问题是否出在输入字段上，并在接收数据的控制器变量上使用了 vardump，结果为 0。

在我意识到一切都很好之后..唯一不好的，也是我唯一不明白它是如何工作的是 .htaccess 文件。

PS：正确的 .htaccess 只是从 codeigniter 框架的 url 中删除了 index.php 文件！

所以恢复我如何从下面的传统 htaccess 文件中启用任何 "data request (post, get, etc..)" :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/ [L]

Answer 1

我解决了将模型更改为 :

的问题

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Login_model extends CI_Model {

    function __construct()
    {
        parent::__construct();
    }

    function validate($username, $password){

        $this->db->select('*');
        $this->db->from('tbl_admin_users');
        $this->db->where('username', $username);
        $this->db->where('password', $password);

        $query = $this->db->get();

        return $query;
    }
}

控制器功能为：

public function login_validation(){

        $username = $this->input->POST('username');
        $password = $this->input->POST('password');

        if($username != NULL && $password != NULL)
        {
            $validate = $this->Login_model->validate($username, $password);

            $rows = $validate->num_rows();

            if($rows > 0){

                $data = $validate->row_array();

                $nome  = $data['nome'];
                $apelido = $data['apelido'];
                $id = $data['id'];
                $username = $data['username'];
                $nivel = $data['nivel'];

                $sesdata = array(
                    'nome'  => $nome,
                    'apelido' => $apelido,
                    'username'     => $username,
                    'nivel'     => $nivel,
                    'id' => $id,
                    'logged_in' => TRUE
                );

                $this->session->set_userdata($sesdata);

                // access login for admin
                if($nivel == '0'){
                    redirect(base_url() . 'Admin_Controller');

                // access login for staff
                }elseif($nivel == '1'){
                    redirect(base_url() . 'Admin_Controller/1');

                 // access login for author
                }elseif($nivel == '2'){
                    redirect(base_url() . 'Admin_Controller/2');
                }

            }else{
                echo $this->session->set_flashdata('msg','Username - '.$username.' or Password - '.$password.' is Wrong');
                redirect(base_url().'Login_Controller');
            }
        }else
        {
            echo $this->session->set_flashdata('msg','Nenhum dos campos pode estar em branco !');
            redirect(base_url().'Login_Controller');
        }
    }

还将 .htaccess 文件更改为：

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/ [L]

# ALLOW ONLY NECESSARY REQUEST METHODS
RewriteCond %{REQUEST_METHOD} !^(GET|HEAD|OPTIONS|POST|PROPFIND|PUT) [NC]
RewriteRule .* - [F,L]

Answer 2

很高兴您找到了答案。我建议您简化控制器代码。把它放在答案中，因为使用评论太难了。

您不需要复制 $validate->row_array() 返回的数组，因为您使用了所有相同的索引键。您需要做的就是将“logged_in” key/value 添加到 $data.

// call num_rows() in the if condition
// no need for an extra variable
//$rows = $validate->num_rows();

// $model might return FALSE if something goes wrong in the database
// always make sure it's not FALSE before making a call any result method.
if($validate && $validate->num_rows())
{
    $data = $validate->row_array();
    $data['logged_in'] = TRUE;
}

$this->session->set_userdata($data);

此外，在模型中，您不需要 function __construct()。唯一需要调用 parent::__construct(); 的时候是子 class 在构造函数中做了一些工作。对于为父级扩展的任何 PHP class 都是如此。
