遇到PHP错误严重性：通知消息：未定义的属性：CI_Loader :: $ p文件名：Templates / public.php行号：24

Question

I have gone through this forum and tried all the options provided but nothing is working for me.

I developed a CMS using some Codeigniter tutorial. On my PC everything works well. But on the remote server, it has failed to work. Below is the code. Thanks in advance.

Here is the view

Currently editing:

load->view('Templates/head'); ?>

Controller

 class Pages extends Public_Controller { function __construct(){ parent::__construct(); //$this->load->library('p'); } public function index() { $data['featured_pages'] = $this->Page_model->get_featured(); $this->template->load('public', 'default', 'pages/index', $data); } public function show($slug){ $data['p'] = $this->Page_model->get_by_slug($slug); $this->template->load('public', 'default', 'pages/show', $data); } public function contact(){ // $this->template->load('public', 'default', 'pages/contact') die('contact'); } 

}

Answer 1

The error message comes from that $this->p is not defined. First, it seem that you define $p not $this->p in the controller ( show() -method):

$data['p'] = $this->Page_model->get_by_slug($slug);

So the most probable solution would be to change row 24 and 25 to:

<?php if (isset($p) && $p) : ?> //liine 24
        <?php foreach($p as $page) : ?>
