Display Nested categories

[eluser]shailendra[/eluser]
I tried your previous code you gave on 15 July. I modified the controller code to include sub category

In controller

Code:

function index()
    {
       $this->load->model('category_model');
       $data = array();
       $categories = array();
       $categories = $this->category_model->list_parent_categories();
       $i = 0;
       foreach($categories as $sub_category)
       {
          $categories['sub_category'][$i] =  $this->category_model->list_sub_categories($sub_category->category_id);
          $j=0;
          foreach($categories['sub_category'][$i] as $sub_category1)
          {
            $categories['proj_counts'][$j]=$this->category_model->no_of_projects($sub_category1->category_id);
            $j++;
          }
            $i++;
       }
       // Check the value
       var_dump($categories);
       // If above line works fine, just assign it into the view
        $data['categories'] = $categories;
        $this->load->view('category_view', $data);
    }

In View

Code:

<?php
foreach($categories as $category){
    echo $category->category_name;
    foreach($category['sub_category'] as $lrow){
            echo $lrow['category_name'];
    }
}
?>

I get following error:
Fatal error: Cannot use object of type stdClass as array in C:\Program Files\Apache Group\Apache2\htdocs\codeigniter\application\views\category_view.php on line 4

Below is var_dump($categories) output
