Can't override Blocktopmenu function generateCategoriesMenu

[wayann]

if (!defined('_CAN_LOAD_FILES_'))
    exit;


class BlocktopmenuOverride extends Blocktopmenu
{
	public function generateCategoriesMenu($categories, $is_children = 0)
	{
            die( var_dump ('hello I am an override') );
	}
}

setting up this in the folder override/modules cleared the cache file class_index.php

 

it works if I strip of the parent function but then this override is pointless....

 

any hints of why it doesn't work?

 

I'm on 1.6.0.12

nobody has an answer to that?

[wayann]

it's because blocktopmenu is using private functions instead of protected, proposed patch merged to dev branch of blocktopmenu.

Hello wayann,
 
I'm trying to set an override in order to limit the subcategory levels on the menu but is not working even when is a protected funtion according to the original blocktopmenu.php
 
Is it somethig wrong?
 
if (!defined('_CAN_LOAD_FILES_'))
    exit;
 
class BlockTopMenuOverride extends BlockTopMenu
{
    protected function generateCategoriesMenu($categories, $is_children = 0)
    {
        $html = '';

        foreach ($categories as $key => $category)
        {
            if ($category['level_depth'] > 1)
            {
                $cat = new Category($category['id_category']);
                $link = Tools::HtmlEntitiesUTF8($cat->getLink());
            }
            else
                $link = $this->context->link->getPageLink('index');

            $html .= '<li'.(($this->page_name == 'category'
                && (int)Tools::getValue('id_category') == (int)$category['id_category']) ? ' class="sfHoverForce"' : '').'>';
            $html .= '<a href="'.$link.'" title="'.$category['name'].'">'.$category['name'].'</a>';

            if ($category['level depth'] < 4 && isset($category['children']) && !empty($category['children']))
            {
                $html .= '<ul>';
                $html .= $this->generateCategoriesMenu($category['children'], 1);

                if ((int)$category['level_depth'] > 1 && !$is_children)
                {
                    $files = scandir(_PS_CAT_IMG_DIR_);

                    if (count($files) > 0)
                    {
                        $html .= '<li class="category-thumbnail">';

                        foreach ($files as $file)
                            if (preg_match('/^'.$category['id_category'].'-([0-9])?_thumb.jpg/i', $file) === 1)
                                $html .= '<div><img src="'.$this->context->link->getMediaLink(_THEME_CAT_DIR_.$file)
                                .'" alt="'.Tools::SafeOutput($category['name']).'" title="'
                                .Tools::SafeOutput($category['name']).'" class="imgm" /></div>';
                        $html .= '</li>';
                    }
                }
                $html .= '</ul>';
            }
            $html .= '</li>';
        }
        return $html;
    }
