问题描述
我在CodeIgniter-2.2.1中得到这个错误(致命错误:调用成员函数get()在C:\ xampp \htdocs\ci\application\models\site_model .php on line 6)我不知道为什么会发生这种情况。我是否正确调用函数?第6行是$ this-> load-> model('site_model');
控制器site.php
<?php
类网站扩展CI_Controller {
function index(){
$ this-> load-> model('site_model' );
$ data ['records'] = $ this-> site_model-> getAll();
$ this-> load-> view('home',$ data);
}}
site_model.php
<?php
class Site_model extends CI_Model {
function getAll(){
$ q = $ this-> db-> get('test');
if($ q-> num_rows()> 0){
foreach($ q-> result()as $ row)
{
$ data [] = $ row;
}
return $ data;
}
}
}
?>
home.php视图页
<!DOCTYPE>
< html>
< head>
< title>网站< / title>
< / head>
< body>
< div id =container>
< p>我的视图已加载< / p>
< pre>
<?php print_r($ records);?>
< / pre>
< / body>
< / html>
解决方案
正在加载数据库
$ this-> load-> database();
I keep getting this error in CodeIgniter-2.2.1.(Fatal error: Call to a member function get() on null in C:\xampp\htdocs\ci\application\models\site_model.php on line 6) I am not sure why this is happening. Am I calling the function correctly? Line 6 is $this->load->model('site_model');
controller site.php
<?php
class Site extends CI_Controller{
function index(){
$this->load->model('site_model');
$data['records'] = $this->site_model->getAll();
$this->load->view('home', $data);
}}
site_model.php
<?php
class Site_model extends CI_Model{
function getAll(){
$q = $this->db->get('test');
if($q->num_rows() >0){
foreach ($q->result() as $row)
{
$data[] =$row;
}
return $data;
}
}
}
?>
home.php The view page
<!DOCTYPE>
<html>
<head>
<title>Site</title>
</head>
<body>
<div id="container">
<p>My view has been loaded</p>
<pre>
<?php print_r($records);?>
</pre>
</body>
</html>
解决方案
Are loading the database
$this->load->database();
