Data available for all views in codeigniter

Question

I have a variable, contaning data that should be present in the entire site. Instead of passing this data to each view of each controller, I was wondering if there is a way

Answer 1

If this is not an Variable(value keep changing) then I would suggest to create a constant in the constant.php file under the config directory in the apps directory, if it's an variable keep changing then I would suggest to create a custom controller in the core folder (if not exist, go ahead an create folder "core") under apps folder. Need to do some changes in other controller as mentioned here : extend your new controller with the "CI_Controller" class. Example

open-php-tag if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class LD_Controller extends CI_Controller { } close-php-tag

Here LD_ is my custom keyword, if you want to change you can change it in config.php file under line# 112 as shown here : $config['subclass_prefix'] = 'LD_'; and extend this class in all your controllers as "class Mynewclass extends LD_Controller.. And in LD_controller you've to write the method in which you want to define the variable/array of values & call that array in all over the application as shown here : defining variable : var $data = array(); Method to get values from db through the Model class:

function getbooks()
{
   $books =   $this->mybooks_model->getbooks(); //array of records
   $this->data = array('books'=>$books);
}

---

to call this variable in the views : print_r($this->data['books']);); you will get all the array values... here we've to make sure atleast one "$data" parameter needs to be passed if not no problem you can define this $data param into the view as shown here : $this->load->view('mybookstore',$data);

then it works absolutely fine,,, love to share... have a fun working friends
