无法找到您指定的codeigniter模型

Question

I am unable to get model file User_model.php

i have specified file in models/frontend/user_model.php

Declaration in user_model.php

<?php

class User_model extends CI_Model {}

I have user model in Controller :

<?php

class User_controller extends MY_Controller {

    public function __construct()
    {
        parent::__construct();
        $this->load->model('frontend/user_model');
    }

This is correctly working on my localhost but when i host on my domain it gives such type of errors.

Answer 1

您需要将模型文件从user_model.php重命名为User_model.php。在Windows wampp或xampp中，大小写无关紧要，但是您的生产环境必须在Linux上并且区分大小写，这就是为什么会出现错误的原因。

Answer 2

Did you follow Codeigniter User Guide ?

class User_model extends CI_Model {

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

Your file will be this: application/models/user_model.php

If you use <? as an opening tag (check at the very start of your file), change it to <?php . The server might not allow the shorthand style.

And if you are still unlucky, try this:

 $CI =&get_instance();
 $CI->load->model('articles_model');
 $parameter = $CI->articles_model>getarticle($id);

When making or calling a class you have to use first letter capital of class. Call your model like this.

$this->load->model('frontend/User_model');

I faced this issue too. We have to use first letter capital for classes in codigniter 3.0 or above.

Answer 4

Check for model name. Case sensitive name ignored in localhost . But in server they are treated as different file. I can see your model name is user_model . But Model class is User_model which is in capital letter. Hope this help.
