How to count post view in codeigniter blog - php

Question

I am new in codeigniter and php.
I want to count post view number and store it database.
That means, I want to create a popular post plugin by counting post view.
But i can't do this.
Please anyone help me. Tell the way.
Here is my article Controller..
public function __construct(){
parent::__construct();
$this->load->model('article_m');
}
public function index($category_slug, $id, $slug=NULL){
// Fetch the article
$this->db->where('pubdate <=', date('Y-m-d'));
$this->data['article'] = $this->article_m->get($id);
$this->data['articles'] = $this->article_m->get();
// Return 404 if not found
count($this->data['article']) || show_404(uri_string());
if ($this->uri->segment(1) !== $this->data['cat']->category_slug) {
echo "Hi There, This is wrong";
}
$this->load->view('templates/article', $this->data);
}
}
Here is my Models:
public function get($id = NULL, $single = FALSE){
if ($id != NULL) {
$filter = $this->_primary_filter;
$id = $filter($id);
$this->db->where($this->_primary_key, $id);
$method = 'row';
}
elseif($single == TRUE) {
$method = 'row';
}
else {
$method = 'result';
}
if (!count($this->db->ar_orderby)) {
$this->db->order_by($this->_order_by);
}
return $this->db->get($this->_table_name)->$method();
}
Sorry for my bad english..

Answer 1

$post_id = "???"
if(isset($_COOKIE['read_articles'])) {
//grab the JSON encoded data from the cookie and decode into PHP Array
$read_articles = json_decode($_COOKIE['read_articles'], true);
if(isset($read_articles[$post_id]) AND $read_articles[$post_id] == 1) {
//this post has already been read
} else {
//increment the post view count by 1 using update queries
$read_articles[$post_id] = 1;
//set the cookie again with the new article ID set to 1
setcookie("read_articles",json_encode($read_articles),time()+60*60*24);
}
} else {
//hasn't read an article in 24 hours?
//increment the post view count
$read_articles = Array();
$read_articles[$post_id] = 1;
setcookie("read_articles",json_encode($read_articles),time()+60*60*24);
}

star complex to do?
//function single post, query get by slug and id post
if(!isset($_SESSION['views'. $id]) || (isset($_SESSION['views'. $id]) && $_SESSION['views'. $id] != $id)){
$this->post_m->viewer($id); //load model viewer
$this->session->set_userdata('views'. $id, $id);
}
// Model "post_m"
function viewer($id)
{
$this->db->where('id', $id);
$this->db->set('views', 'views+1', FALSE);
$this->db->update('posts'); //table update
}
$id is id post
