我正在学习https://www.codeigniter.com/user_guide/tutorial/static_pages.html关于学习系统的教程。当它说查看页面时,我收到HTTP 500错误。
正确安装了Codeignitor,并启动了默认的欢迎页面。我只是无法弄清楚我在哪里出错了。
class Pages extends CI_Controller {
public function view($page = 'home')
{
if ( ! file_exists( APPATH . 'views/pages/' . $page . '.php'))
{
// Whoops, we don't have a page for that!
show_404();
}
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view('pages/'.$page, $data);
$this->load->view('templates/footer', $data);
}

APPPATH
代替APPATH
。
答案 1 :(得分:0)
就像已经回答的那样,它是APPPATH
。
APPPATH是一个包含字符串的常量,如果从控制器调用该字符串,则返回“application /”
试试这个:
public function view($page = 'home')
{
if ( ! file_exists( APPPATH . "views/pages/{$page}.php"))
{
// Whoops, we don't have a page for that!
show_404();
} else {
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view("pages/{$page}", $data);
$this->load->view('templates/footer', $data);
}
}
