CodeIgniter View Blog Post Page - php

Question

Hello guys i am trying to create a blog. The first home page is ok.. i am getting the shrot description and the categories from the database but...i have problems with the links:
this are my controller functions:
public function index()
{
$this->load->model('Model_cats');
$data['posts'] = $this->Model_cats->getLivePosts(10);
$data['cats'] = $this->Model_cats->getTopCategories();
$data['title'] = 'Welcome to Paul Harbuz Blog Spot!';
$data['main'] = 'public_home';
$this->load->vars($data);
$this->load->view('template', $data);
}
public function category($id)
{
$data['category'] = $this->Model_cats->getCategory($id);
$data['posts'] = $this->Model_cats->getAllPostsByCategory($id);
$data['cats'] = $this->Model_cats->getTopCategories();
$data['title'] = $data['category']['name'];
$data['main'] = 'public_home';
$this->load->vars($data);
$this->load->view('template', $data);
}
public function post($id)
{
$data['post'] = $this->Model_cats->getPost($id);
$data['comments'] = $this->Model_cats->getComments($id);
$data['cats'] = $this->Model_cats->getTopCategories();
$data['title'] = $data['post']['title'];
$data['main'] = 'public_post';
$this->load->vars($data);
$this->load->view('template');
}
this are my model function:
function getTopCategories()
{
$this->db->where('parentid',0);
$query = $this->db->get('categories');
$data = array();
if ($query->num_rows() > 0)
{
foreach ($query->result_array() as $row)
{
$data[$row['id']] = $row['name'];
}
}
$query->free_result();
return $data;
}
function getLivePosts($limit)
{
$data = array();
$this->db->limit($limit);
$this->db->where('status', 'published');
$this->db->order_by('pubdate', 'desc');
$query = $this->db->get('posts');
if($query->num_rows() > 0)
{
foreach($query->result_array() as $row)
{
$data[] = $row;
}
}
$query->free_result();
return $data;
}
function getCategory($id)
{
$data = array();
$this->db->where('id',$id);
$this->db->limit(1);
$query = $this->db->get('categories');
if($query->num_rows() > 0)
{
$data = $query->row_array();
}
$query->free_result();
return $data;
}
function getAllPostsByCategory($catid)
{
$data = array();
$this->db->where('category_id', $catid);
$this->db->where('status', 'published');
$query = $this->db->get('posts');
if($query->num_rows() > 0)
{
foreach($query->result_array() as $row){
$data[] = $row;
}
}
$query->free_result();
return $data;
}
function getPost($id)
{
$data = array();
$this->db->where('id',$id);
$this->db->limit(1);
$query = $this->db->get('posts');
if ($query->num_rows() > 0)
{
$data = $query->row_array();
}
$query->free_result();
return $data;
}
and in the view page i have something like this:
if ( count($posts) )
{
foreach ($posts as $key => $list)
{
echo '<h2>'.$list['title'].'</h2>';
echo auto_typography(word_limiter($list['body'], 200));
echo anchor('post/'.$list['id'],'read more >>');
}
echo '<br/><br/>';
}
I'm getting the post id in the url but.. i don't know why the page is not found.

Answer 1

You have to add the controller name to the anchor uri segments.
echo anchor('CONTROLLER/post/'.$list['id'],'read more >>');
More on this topic in the CodeIgniter URLs documentation.
If you want a URL like http://example.com/post/123 then you have to add the following to your application/config/routes.php file:
$route['post/(:num)'] = "CONTROLLER/post/$1";
More on routing is also available in the documentation.
