Hi.

$id_product = 14;

$getCategories = Product::getProductCategories($id_product);

/* return id_categories */
$cats = array();
foreach ($getCategories as $category)
{
	$cats[] = $category['id_category'];
}

echo implode(' | ', $cats);

 

Or:

$id_product = 14;
$id_lang = $this->context->language->id;

$getCategories = Product::getProductCategoriesFull($id_product, $id_lang);

foreach ($getCategories as $category)
{
	$category_id = $category['id_category'];
	$category_name = $category['name'];
	$category_link_rewrite = $category['link_rewrite'];

	echo $category_id . ' - ' . $category_name . ' - ' . $category_link_rewrite .'<br />';

}

Hi.

It is always better to use Prestashop functions, the output data can be formatted better.

GROUP_CONCAT and SEPARATOR can be used in SQL.

SELECT 
a.`id_product`, 
b.`name` AS `name`, 
a.`reference`, 
a.`price` AS `price`, 
sa.`active` AS `active`, 
shop.`name` AS `shopname`, 
a.`id_shop_default`, 
image_shop.`id_image` AS `id_image`, 
cl.`name` AS `name_category`, 
(SELECT GROUP_CONCAT(cp.`id_category` SEPARATOR ' - ') 
FROM `ps_category_product` cp
WHERE cp.id_product = a.`id_product`) AS `categories`,
sa.`price`, 
0 AS `price_final`, 
a.`is_virtual`, 
pd.`nb_downloadable`, 
sav.`quantity` AS `sav_quantity`, 
sa.`active`, 
IF(sav.`quantity`<=0, 1, 0) AS `badge_danger`
FROM `ps_product` a
LEFT JOIN `ps_product_lang` b ON (b.`id_product` = a.`id_product` AND b.`id_lang` = 4 AND b.`id_shop` = 1) 
LEFT JOIN `ps_stock_available` sav ON (sav.`id_product` = a.`id_product` AND sav.`id_product_attribute` = 0 AND sav.id_shop = 1 AND sav.id_shop_group = 0 ) 
JOIN `ps_product_shop` sa ON (a.`id_product` = sa.`id_product` AND sa.id_shop = a.id_shop_default) 
LEFT JOIN `ps_category_lang` cl ON (sa.`id_category_default` = cl.`id_category` AND b.`id_lang` = cl.`id_lang` AND cl.id_shop = a.id_shop_default) 
LEFT JOIN `ps_shop` shop ON (shop.id_shop = a.id_shop_default) LEFT JOIN `ps_image_shop` image_shop ON (image_shop.`id_product` = a.`id_product` AND image_shop.`cover` = 1 AND image_shop.id_shop = a.id_shop_default) 
LEFT JOIN `ps_image` i ON (i.`id_image` = image_shop.`id_image`) LEFT JOIN `ps_product_download` pd ON (pd.`id_product` = a.`id_product` AND pd.`active` = 1) 
WHERE 1 
ORDER BY a.`id_product` ASC;

You need to query the ps_category_product table to get the other categories besides the default.
