Codeigniter error 404 on news item tutorial - php

Question

I saw plenty of questions and tried all those fixes similar to this issue but could not get this resolved. Please help.
I am following codeigniter news item tutorial. I displayed news from database. When I click on a link to view particular news it throws 404.
Here is the code:
Controller:
<?php
class News extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('news_model');
$this->load->helper('url');
}
public function index() {
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
public function view($slug) {
$data['news_item'] = $this->news_model->get_news($slug);
// var_dump($data);exit;
if (empty($data['news_item'])) {
show_404();
}
$data['title'] = $data['news_item']['title'];
$this->load->view('templates/header', $data);
$this->load->view('news/view', $data);
$this->load->view('templates/footer');
}
}
Model:
<?php
class News_model extends CI_Model {
public function __construct() {
$this->load->database();
}
public function get_news($slug = FALSE) {
if ($slug === FALSE) {
$query = $this->db->get('news');
return $query->result_array();
}
$query = $this->db->get_where('news', array('slug' => $slug));
return $query->row_array();
}
}
View:
news.php
<?php
class News extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('news_model');
$this->load->helper('url');
}
public function index() {
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';
$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}
public function view($slug) {
$data['news_item'] = $this->news_model->get_news($slug);
// var_dump($data);exit;
if (empty($data['news_item'])) {
show_404();
}
$data['title'] = $data['news_item']['title'];
$this->load->view('templates/header', $data);
$this->load->view('news/view', $data);
$this->load->view('templates/footer');
}
}
view.php
<?php
echo '<h2>' . $news_item['title'] . '</h2>';
echo $news_item['text'];
routes:
$route['news/(:any)'] = 'news/view/$1';
$route['news'] = 'news';
$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';
Base url is blank in config.
CI version is 2.1.4 (latest)
This URL shows all the news items correctly - http://localhost/educon/index.php/news/
This URL throws 404 - http://localhost/educon/index.php/news/view/n1

Answer 1

The problem is in your routes. Your routes file have the line as
$route['news/(:any)'] = 'news/view/$1';
But your url is
http://localhost/educon/index.php/news/view/n1
This will redirect to
http://localhost/educon/index.php/news/view/view/n1
In your view($slug) method you have a parameter. You dump this $slug in first line of view() and check it.

Answer 2

I had a similar issue. For me, the routes.php file was fine (by "fine" I mean it matched what the tutorial said to do (also version 2.1.4)), but my views/news/index.php file generated the news article link like so:
<p>View article</p>
After noting the issue with the generated path, I dropped news from the path and this worked:
<p>View article</p>
So links went from: /news/news/news-item-2 to /news/news-item-2
And given the tutorial's routing:
$route['news/(:any)'] = 'news/view/$1';
That then made sense.

Answer 3

I encountered this just now, and I also just copied everything in the tutorial, the thing is, it is in the arrangement of the routing, at first, I just added the new codes in routes.php like this....
$route['default_controller'] = 'pages/view';
$route['(:any)'] = 'pages/view/$1';
$route['news'] = 'news';
$route['news/create'] = 'news/create';
$route['news/(:any)'] = 'news/view/$1';
then change it to
$route['news/create'] = 'news/create';
$route['news/(:any)'] = 'news/view/$1';
$route['news'] = 'news';
$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';
And now it works like a charm...

Answer 4

Using slug without spaces worked for me.
The 'News Section' part of the tutorial tells you to create some seed records. In my case, my slug contained spaces and I got the 404 error. Removing the spaces fixed this. (CodeIgniter v.3.1.4)

Answer 5

try to check your link that goes to news listing it should be something like this
<li>News</li>
you need to change it to read as follows, because i tried it out and its the fix for the problem
<li>News</li>
It will be great if someone with more experience can guide on how to correct this in the route.php
below is my route.php
$route['news/(:any)'] = 'news/view/$1';
$route['news'] = 'news/index';
$route['(:any)'] = 'pages/view/$1';
$route['default_controller'] = 'pages/view';
note it will work even if you make the second line as:
$route['news'] = 'news';
and .htaccess is as:
RewriteEngine on
RewriteCond $1 !^(index\.php|assets|images|js|css|uploads|favicon.png)
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.*)$ ./index.php/$1 [L]
