PyroCMS v0.9.9

For those who really needs submenu solution for their PyroCMS project.

1. add parent_id column to your navigation_links column
2. add parent_id rules to your admin controller inside navigation module

Code:

$rules['parent_id'] = 'trim|numeric';

3. Admin_Controller add this code under _construct function

Code:

if($parentss = $this->navigation_m->get_parents())
        {
            foreach($parentss AS $parents)
            {
                $this->data->parentss[$parents->id] = $parents->title;
            }
        }

4. Add this code to navigation_m model

Code:

function get_parents()
    {
        $this->db->select('navigation_links.*');
        $this->db->where('parent_id',0);
        return $this->db->get('navigation_links')->result();
    }

5. Add this code to form.php at navigation module

Code:

<li class="even">
                    <label for="target">&lt;?php echo lang('nav_parent_label'); ?&gt;</label>
                    &lt;?php echo form_dropdown('parent_id', array(lang('nav_link_parent_select_default'))+$parentss, $navigation_link->parent_id) ?&gt;
                </li>

6. Add this function to navigation_helper

Code:

function generateMenu($array, $parent = 0, $level = 0)
{

  //
  // Reset the flag each time the function is called
  //
  $has_children = false;

  //
  // Loop through each item of the list array
  //
  foreach($array as $key => $value)
  {
    if ($value['parent_id'] == $parent)
    {                  

      //
      // Only print the wrapper ('<ul>') if this is the first child (otherwise just print the item)      
      // Will be false each time the function is called again
      //
      if ($has_children === false)
      {
        //
        // Switch the flag, start the list wrapper, increase the level count
        //
        $has_children = true;  

        echo '<ul class="level-' . $level . '">';

        $level++;
      }

      //
      // Print the list item
      //
      echo '<li><a href="?id=' . $value['id'] . '">' . $value['title'] . '</a>';

      //
      // Repeat function, using the current item's key (id) as the parent_id argument
      // Gives us a nested list of subcategories
      //
      generateMenu($array, $key, $level);

      //
      // Close the item
      //
      echo '</li>';


    }

  }

  //
  // If we opened the wrapper above, close it.
  //
  if ($has_children === true) echo '</ul>';


}

7. Call this menu inside leftnav.php "theme view folder"

Code:

foreach(navigation('sidebar') as $nav_link):
        $menus[$nav_link->id] = array(
            'id' => $nav_link->id,
            'title' => $nav_link->title,
            'parent_id' => $nav_link->parent_id
          );

    endforeach;
    
    echo generateMenu($menus);

8. Voila! main menu and sub menu solution is ready, but I hope in the next version it will be more easily done.
