Get the Itemid

Hi there,

I am building a product scroller for hikashop. Everything is working correctly except the breadcrumb when we view the product. At the moment the scroller works with only category at a time. Currently when you click on the link to view a product we get the following breadcrumb

Home > product category > Category A > Category B > Category C > Product Name

I don't want 'product category' to appear. We want the breadcrumb to be:

Home > Category A > Category B > Category C > Product Name

To do so we need the Itemid value for Category A in the URL. Correct? Does Hikashop already have a function that allows you to obtain this value? Thanks

Hello Nicolas, thanks for the big pointer. Here is a working version.

function getItemidFromCategory($category_id) {
    $config = & hikashop::config();
    $values = $config->values;
    foreach ($values as $key => $value) {
      if (preg_match('#menu_([0-9]+)#', $key, $match)  && is_string($value->config_value)) {
        $options = unserialize(base64_decode($value->config_value));
        if ($options['selectparentlisting'] == $category_id) {
          return $match[1];
        }
      }
    }
    return false;
  }

Hi Nicolas, okay we took you improvements and we have added them tothe hikashop_products.php search file. So we now have perfect breadcrumbs from search results! Yay! We have worked on version 1.4.9

In line 132 we modified the line to:

$select = ' a.product_id AS id, a.product_name AS title, a.product_created AS created , a.product_description AS text, "'.$new_page.'" AS browsernav, b.category_id as category_id';

if(empty($item_id)){
          $Itemid = $this->getItemidFromCategory($rows[$k]->category_id);
          if(!empty($Itemid)){
            $item_id='&Itemid='.$Itemid;
            if($this->params->get('full_path',1)){
              $menuClass = dacshop::get('class.menus');
              $menuData = $menuClass->get($item_id);
              if(!empty($menuData->dacshop_params['selectparentlisting'])){
                $parent = '&category_pathway='.(int)$menuData->dacshop_params['selectparentlisting'];
              }
            }                     
          }
        }

I see this solutaion for obtaining the itemid has been removed in version 1.5.3. This now results in blank pages when the user searches for a category and clicks to display the category. In the category search plugin we have not set the Itemid because our menu structure is:

Home
Category1 > Subcategory1 > AnotherSubcategory1
Category2 > Subcategory2 > AnotherSubcategory2
Category3 > Subcategory3 > AnotherSubcategory3
Category4 > Subcategory4 > AnotherSubcategory4

So you can we don't have single itemid that satisfies the setting for each view. The solution in these posts worked well. I presume when the the manufacture option was added it was removed for some reason. (edit - sorry, getting confused. This was implemented for the product search - now I am going see if something similar can be implemented to get the itemid if the itemid is not set in the category plugin.)

Okay. I seem to have a solution that is working for the categories search and have also resolved a bug with the product search. I am sending you them by email.

Hello,
does it comes to a solution to find the correct menu-itemid for each product listed ?
Is there a function that could be used to retrieve it in Content Display module to set the itemid in the $link variable ?

I suppose it should be updated in the code of listing_img_title.php as an override ...
... an option in module that say "auto get product item-id if exists !" would also be a great way !

Hello,
I've set "Force canonical URLs on listings = Use canonical URL and generate it if missing"
but the Itemid is always still the same for each product in list.
Looking at the code of listing_img_title.php doesn't seems to try to get the menu item anywhere,
it couldn't be easy to find, not just with a simple query, because I suppose we have to search in all menu items for a param like {product_id: ... }

I've made a fast update of the code to try to retrieve the menu item id.
I've updated two files in components/com_hikashop/views/product/tmpl/
(I think that once these becomes working these could be put as overrides in template joomla dir)

Add this code to listing_div.php

$db = JFactory::getDbo();
	$query = $db->getQuery(true);
	$query->select('*');
	$query->from($db->quoteName('#__menu'));
	$query->where($db->quoteName('link')." = ".$db->quote('index.php?option=com_hikashop&view=product&layout=show'));	 
	$db->setQuery($query);
	$result_menu = $db->loadAssocList();	
	$prod_arr = array();
	foreach ($result_menu as $res_item)
	{
		$prod_param = json_decode($res_item['params']);
		$prod_id = $prod_param->product_id;
		$prod_arr[$prod_id] = $res_item['id'];
	}
	//print_r($prod_arr);
	$this->prod_arr = $prod_arr;

	$itemid = (int)$this->prod_arr[$this->row->product_id];
	$link = hikashop_completeLink('product&task=show&cid='.$this->row->product_id.'&name='.$this->row->alias."&Itemid=".$itemid);

Hi
can i have more information about
- the itemid : id of the menu ( module) or one of the id of a menu ( one of the list title of the menu )
- the relation beetween itemid and Canonical URL ?

thank's

I think he's asking what kind of id is the itemid we're talking about,
then it is the id of each menu item useful when you need to enable a module for a certain page by the settings of the module itself.
If this element isn't present in the url the module will not be loaded.
