無法在Codeigniter中加載模型

Question

我有一個名爲register_model.php的模型，我在我的控制器（register_controller.php）中加載了一個函數。模型文件被放入模型文件夾本身。不過，我得到這個錯誤。

一個錯誤時遇到

無法找到您所指定的型號：register_model

Answer 1

也許你應該包括您的控制器內的模型，嘗試包含後parent::__construct

這看起來應該像這樣：

類註冊擴展是CI_Controller {

function __construct() { 
    parent::__construct(); 
    $this->load->model('register_model'); 
} 

，或者如果你使用這種模式在大多數控制器，你可以使用自動加載包含它，去/配置/自動加載.php搜索$ autoload ['model']並在合適的陣列中添加你的模型

Answer 2

首先在你的控制器中加載你的模型..

function __construct() { 
parent::__construct(); 
$this->load->model('register_model'); 
} 

這會爲你工作...
