hi,
I developing new plugin(system) for Hikashop.
how can get Category name of Product ?
this is my code:

function getProductHikashopInfo() {
		//load HikaShop if not already loaded
		if(!defined('DS'))
			define('DS',DIRECTORY_SEPARATOR);
		if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php'))
					return true;
		//get product id
		$product_id = (int)hikashop_getCID('product_id');
		if(empty($product_id ))
		 return true;

		// load product
		$productClass = hikashop_get('class.product');
		
		$categoryClass = hikashop_get('class.category');
		$product_category = $categoryClass->get($product_id )->category_name;
                echo $product_category;   // echo "Root"
}
this code output ===> "Root" instead of product category name

Hi,

Your code should be:

function getProductHikashopInfo() {
		//load HikaShop if not already loaded
		if(!defined('DS'))
			define('DS',DIRECTORY_SEPARATOR);
		if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php'))
					return true;
		//get product id
		$product_id = (int)hikashop_getCID('product_id');
		if(empty($product_id ))
		 return true;
		
		$categoryClass = hikashop_get('class.category');
		$categories = $categoryClass->getCategories($product_id);
		$product_category = reset($categories)->category_name;
                echo $product_category;
}

Hi,

That error doesn't come from the code I provided.
Normally, if you activate the "debug" setting of the Joomla configuration, you should get the call stack of the error so you should be able to see in which line of which file the issue is.

Hi,

I know, I gave you:
$categoryClass = hikashop_get('class.category');
$categories = $categoryClass->getCategories($product_id);
but it should be:
$productClass = hikashop_get('class.product');
$categories = $productClass->getCategories($product_id);

Hello.

How can I get the current (displayed) category id in a custom plugin without knowing the product id or anything else?
(product listing view)

Ty.

Hi,

In the product listing view, you can get the current category ID from the URL parameter using:

$category_id = hikaInput::get()->getInt('cid');

If you want to get the category object with its name:
if(!defined('DS')) define('DS',DIRECTORY_SEPARATOR);
if(!include_once(rtrim(JPATH_ADMINISTRATOR,DS).DS.'components'.DS.'com_hikashop'.DS.'helpers'.DS.'helper.php')) return;

$category_id = hikaInput::get()->getInt('cid');
if(!empty($category_id)) {
    $categoryClass = hikashop_get('class.category');
    $category = $categoryClass->get($category_id);
    echo $category->category_name;
}
Note that if you are in the context of a HikaShop view file (like a listing template), the category ID is often already available in the $this->pageInfo->filter->cid variable.
