codeigniter sidebar problem

i want to pass some data to my sidebar but i dont know how to do it best practice,

i have a template file like this:

<?php

$this->load->view('include/header');

$this->load->view($main_content);

$this->load->view('include/footer');

?>

i make a helper file like this:

<?php


    //Getting all the Reviews and put them on the includes/header.php 
    function sidebar()
    {
        //Get the instance of the framework
        $CI=& get_instance();


        //Getting data from sidebarModel
        $CI->load->model('sidebar_model');
        $sidebarData = $CI->sidebar_model->getSidebarReviews();

        return $sidebarData;
    }

and then i think i need to go to my header.php file and do something there to get the data 开发者_如何学运维out in a foreach, but i dont know how.

hope some one can help me out

best regards Sim

Pass the data as an array

$data['mykey']='myvalye';
$this->load->view('include/header',$data);

Then simply echo $mykey in the view

You can pass multiple data for example $data['sidebar']='mysidebar'; , if you are still not clear then please comment below.

Edit Keep the helper same as you described in question.

Write this in controller

$data['sidebarRow']=sidebar();
$this->load->view('template',$data);

Write this in view

echo $sidebarRow;

You can load variables so they become global in all of your views and subviews.

Use $this->load->vars($data_array) whenever you have any data to be used globally in your views.

This method can be used multiple times anywhere in your application and will merge any data you add.

Another answer would be to autoload your sidebar helper and then just call that in your view file (your header?!)

$rows = sidebar();
foreach($rows as $row):
  // Do something with your sidebar row
endforeach;
