我有一个结构良好、编码良好的表单，但当我使用post向我的控制器发送数据时。。接收post数据的变量为空。我尝试向用户发送警报，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vardump，结果为0

当我意识到一切都很好。。唯一一件不是的事，也是唯一一件我真的不明白它是如何工作的，就是.htaccess文件

PS:corrent.htaccess只是从codeigniter框架的url中删除index.php文件

那么，如何从下面的传统htaccess文件中启用任何“数据请求（post、get等）”：

<?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->where('username', $username);
        $this->db->where('password', $password);
        $result = $this->db->get('tbl_admin_users', 1);
        return $result;
    }
}



我已解决问题，将模型更改为：


<?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;
    }
}


还将.htaccess文件更改为：


RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

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



很高兴你找到了答案。我建议您简化控制器代码。把它放在回答中，因为使用评论太难了

您不需要复制
$validate->row_array（）
返回的数组，因为您使用的索引键都相同。您只需将“登录”键/值添加到
$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\uu-construct（）
。唯一需要调用
parent:：\uu-construct（）；
的时间是如果子类在构造函数中做了一些工作。这对于为父类扩展的任何PHP类都是正确的。
要调试，请尝试echo“username-" . $用户名//不+是，我尝试过，但回声的结果是0我不知道codeigniter-3，方法post区分大小写$something=$this->input->post（'something'）；我明白了，等等，现在我添加了（.）来调试，数据来到了变量中，但即使如此，即使使用正确的数据，也没有传递条件$validate->num_rows>0模型有任何问题吗？您不应该需要
RewriteCond%{REQUEST_METHOD}…
指令。在视图中，您应该更改
site\u url（'index.php/Login\u Controller/Login\u validation'）
到
site\u url（'Login\u Controller/Login\u validation'）
，因为
site\u url
自动添加
index.php


// 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);
