Question

Hi I’m wondering how to do just a simple visit counter that stores the information into a file the format could be something like: Date | # Visits, this is just a POC that I’m trying to do here nothing complicated I just want to get use to this framework.

I was trying to use the file helper and the string helper to read the file and then subtract the date or split the content and use a loop to iterate the and update the current date

this is the code so far …

namespace libraries;

class VisitCounter {

    function __construct() {
        $this->load->library('file');
        $this->load->helper('string');
    }

    function trackVisit(){
        $file= read_file('./visits.txt');

        if ( ! write_file('./visits.txt', $file)){
            echo 'Unable to write the file';
        }
    }
}

Any Ideas, I need to know how to split the string or if someone has a better approach.

I created a model for doing that:

class Count_model extends CI_Model{

    function __construct(){
        parent::__construct();
    }

    function increment(){
        $this->db->set('total', 'total+1', FALSE);
        $this->db->update('count');
    }

    function get_total(){
        $query = $this->db->get('count');
        if($query->num_rows()>0){
            $row = $query->row();
            return str_pad($row->total, 6 , "0", STR_PAD_LEFT);
        } else {
            return FALSE;
        }
    }

}

Heres the structure:

CREATE TABLE IF NOT EXISTS `count` (
  `total` int(10) unsigned NOT NULL DEFAULT '0',
  PRIMARY KEY (`total`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
