[Solved] Editing Categories Block to show sub-cats of current cat!

[adammontague]

Hi,

I'm in need of a bit of expert help.

I would like to display the categories block with only the subcategories of the currently viewed category (does that make sense?!)

Any help reeeally appreciated!

1. Go to your modules folder and make a copy/duplicate of your blockcategories folder and rename it with blockcategories2 for example.
2. Enter in the blockcategories2 folder and rename the blockcategories.tpl and blockcategories.php to blockcategories2.tpl and blockcategories2.php.
3. Open up your blockcategories2.php and replace all blockcategories words to blockcategories2.

4. in blockcategories2.php replace hookLeftColumn method with:

   public function hookLeftColumn($params)
   {
       global $smarty, $cookie;

       $id_customer = (int)($params['cookie']->id_customer);
       $id_group = $id_customer ? Customer::getDefaultGroupId($id_customer) : _PS_DEFAULT_CUSTOMER_GROUP_;
       $id_product = (int)(Tools::getValue('id_product', 0));
       $id_category = (int)(Tools::getValue('id_category', 0));
       $id_lang = (int)($params['cookie']->id_lang);
       $smartyCacheId = 'blockcategories2|'.$id_group.'_'.$id_lang.'_'.$id_product.'_'.$id_category;

 if($id_category)
   $category = new CategoryCore($id_category,$id_lang);
 else
   $category = Category::getRootCategory ($id_lang);
       $id_category = $category->id;

       Tools::enableCache();
       if (!$this->isCached('blockcategories2.tpl', $smartyCacheId))
       {
           $maxdepth = Configuration::get('BLOCK_CATEG_MAX_DEPTH');

           if (!$result = Db::getInstance(_PS_USE_SQL_SLAVE_)->ExecuteS('
               SELECT c.id_parent, c.id_category,c.nleft,c.nright, cl.name, cl.description, cl.link_rewrite
               FROM `'._DB_PREFIX_.'category` c
               LEFT JOIN `'._DB_PREFIX_.'category_lang` cl ON (c.`id_category` = cl.`id_category` AND `id_lang` = '.$id_lang.')

               $resultParents[$row['id_parent']][] = &$row;
               $resultIds[$row['id_category']] = &$row;
           }
           $blockCategTree = $this->getTree($resultParents, $resultIds, Configuration::get('BLOCK_CATEG_MAX_DEPTH'),$id_category);

           unset($resultParents);
           unset($resultIds);
           $isDhtml = (Configuration::get('BLOCK_CATEG_DHTML') == 1 ? true : false);

           if (Tools::isSubmit('id_category'))
           {
               $cookie->last_visited_category = $id_category;
               $smarty->assign('currentCategoryId', $cookie->last_visited_category);
           }
           if (Tools::isSubmit('id_product'))
           {
               if (!isset($cookie->last_visited_category) OR !Product::idIsOnCategoryId($id_product, array('0' => array('id_category' => $cookie->last_visited_category))))

           }
           $smarty->assign('blockCategTree', $blockCategTree);

           if (file_exists(_PS_THEME_DIR_.'modules/blockcategories2/blockcategories2.tpl'))
               $smarty->assign('branche_tpl_path', _PS_THEME_DIR_.'modules/blockcategories2/category-tree-branch.tpl');
           else

           $smarty->assign('isDhtml', $isDhtml);
       }
       $smarty->cache_lifetime = 31536000; // 1 Year
       $display = $this->display(__FILE__, 'blockcategories2.tpl', $smartyCacheId);
       Tools::restoreCacheSettings();
       return $display;
   }

That's great!! I needed to change a couple of lines for it to work exactly how I needed but I wouldn't have had a chance without your help! Thank you!

Hi,

 

I would like to do exactly what Adammontague wanted to do. So I have followed all your explanation, but I do not know how to activate my second module "blockcategories2.tpl ".

I tried trough the Back Office, but I don't succeded to find how to install this second module : there is no "add new module" button...

I'm sure it's very simple...

 

Thanks in advance !!

That's work perfectly

But how can we undisplay the block in the last category (display of the product list) ?

Otherwise, it will display a empty block

[cheekymang]

Cracker! Works in 1.5.3.1

I too had trouble setting up a "blockcategories2" module. I was going to research it but I need this done.

 

So I changed the code in my blockcategories.php (yeah I guess I probably shouldn't but it works) changing in the code any reference of "blockcategory2" to "blockcategory" in the code.

 

I also want to undisplay the block in the last category. Time for research.

 

Thanks heaps apug!

I have tried this solution on 1.5.3.1 and it works, thanks a lot to apug. I'd like to have a slightly different behaviour, when i'm inside a subcategory (lvl2) if it doesn't have lower levels i don't see anything in the category block, and it's not useful to go back to parent level , Is it possible to change the code in a way that when in lvl2 subcategory it still shows also the lvl 1 parent category?

Thanks
