Prestashop 1.6 Hooks

andtrx · July 21, 2022

Hello, I need 2 hooks, and no matter which ones I try, they dont seem to work.

1. I need a hook for whenever an order is edited from the backoffice.
When the order changes status and when the admin ads or removes a product and saves the order.

2. I need another hook for whenever a new product is added / edited from the backoffice.

My module looks as follows:

    public function install()
    {
        if (parent::install() && $this->registerHook('displayHeader') && $this->registerHook('displayOrderConfirmation') && $this->registerHook('updateOrderStatus')  && $this->registerHook('addproduct') ) {
            return true;
        }

        return false;
    }

    public function hookdisplayOrderConfirmation($params)
    {

        $externalIdMobilPay = str_replace('%', '#', Tools::getValue('orderId'));
        $externalIdEuPlatesc = Tools::getValue('ep_id');

        if (isset($externalIdMobilPay)) {
            $externalId = $externalIdMobilPay;
        } else if (isset($externalIdEuPlatesc)) {
            $externalId = $externalIdEuPlatesc;
        } else {
            $externalId = "";
        }

        $cartId = $params['objOrder']->id;
        $order = new SeniorErpSendOrder;
        $order->createOrder($cartId, $externalId);

    }

    public function hookupdateOrderStatus($params)
    {
        die('exit');
    }

    public function hookaddproduct($params)
    {
        die('exit');
    }

The hookdisplayOrderConfirmation works without any problem.
The other two, dont
I also tried re-installing the module.

I found the hooks here: https://mypresta.eu/en/art/developer/prestashop-hook-list.html

Thanks,

Hi. It is recommended to look for the official docs, this is the list of hooks for prestashop 1.7 and you might be able to use most of them. Just take a look at: https://devdocs.prestashop.com/1.7/modules/concepts/hooks/list-of-hooks/

actionObject<ObjectName>UpdateAfter
- eg: actionObjectOrderUpdateAfter
- This hook gets fired after an existing Order gets updated in any way.
actionObjectOrderHistoryAddAfter
- This hook gets fired after a new Order History is added. Just after order status update.
actionObjectProductUpdateAfter
- This hook gets fired after an existing Product gets updated.

@stifler97 so based on what you re saying, this should work:

    public function install()
    {
        if (parent::install() && $this->registerHook('displayHeader') && $this->registerHook('displayOrderConfirmation') && $this->registerHook('updateOrderStatus') && $this->registerHook('actionOrderEdited') && $this->registerHook('actionObjectProductUpdateAfter')) {
            return true;
        }

        return false;
    }

    public function hookactionObjectProductUpdateAfter($params)
    {
        die('updated product');
    }

But it does not ... nothing happens when I go into a product and I change its description for example

Did you follow the rules? https://devdocs.prestashop.com/1.7/modules/concepts/hooks/

Just read the documentation and do as they say. If there is a problem do not hesitate to ask more questions.

Hey,

Yes I did read those but for some reason for me hooks like this hookActionObjectProductAddBefore its not working (if I add the classname is not working).
So I tried to hack it using the regular:
"Hook::exec('actionObjectAddBefore', array('object' => $this));" which is working

What I am trying to do is execute some code after a new combination is added, first I store a cookie with current combinations, and in this function:
" public function hookActionObjectAddAfter($params)"
I am getting the combinations again and trying to check if a new one was created.

Everything works fine except the fact that the combination code, is executed after the function below.. therfore I always get the same combination.

" public function hookActionObjectAddAfter($params)"

    public function hookActionObjectAddBefore($params)
    {

        if ($params['object']->object_type === "Product") {

            $product_obj = new Product( $params['object']->object_id, false, $language, $this->context->shop->id);

            $combinations = $product_obj->getAttributeCombinations( $language );


            $parentProduct['productId'] =  $params['object']->object_id;

            foreach($combinations as $combination) {
                $parentProduct['combination'][$combination['reference']]['id_attribute'] = $combination['id_attribute'];
                $parentProduct['combination'][$combination['reference']]['id_product_attribute'] = $combination['id_product_attribute'];
            }

            $cookie = new Cookie('existsNewComibinationProduct');
            $cookie->setExpire(time() + 21 * 60);
            $cookie->existsNewComibinationProduct = json_encode($parentProduct);
            $cookie->write();

        }

    }

    public function hookActionObjectAddAfter($params)
    {

        if ($params['object']->object_type === "Product") {

            $cookie = new Cookie('existsNewComibinationProduct');
            $existsNewComibinationProduct = json_decode($cookie->existsNewComibinationProduct, true);

            $product = new Product( $existsNewComibinationProduct['productId'], false, 2);

            $combinations = $product->getAttributeCombinations(2);

            if ( count($combinations)+1 > count($existsNewComibinationProduct['combination']) &&  $params['object']->object_id == $existsNewComibinationProduct['productId']) {
                $items = [];
                foreach ($combinations as $combination) {
                    if (!array_key_exists($combination['reference'], $existsNewComibinationProduct['combination'])) {
                        $name = $combination['group_name'] . ' - ' . $combination['attribute_name'];
                        $items[$combination['id_product_attribute']]["name"] = htmlspecialchars($product->name . ' (' . $name . ')');
                        $items[$combination['id_product_attribute']]["reference"] = $combination['reference'];
                        $items[$combination['id_product_attribute']]["minimal_quantity"] = $combination['minimal_quantity'];
                    }
                }
            }


            echo "<pre>";
            print_r($items);
            echo "</pre>";
            die;


        }
    }

I am currently stuck.

This is my ObjectModel.php (in case it helps anyone)

public function add($autodate = true, $null_values = false)
	{
		if (!ObjectModel::$db)
			ObjectModel::$db = Db::getInstance();

		if (isset($this->id) && !$this->force_id)
			unset($this->id);

		// @hook actionObject*AddBefore
		Hook::exec('actionObjectAddBefore', array('object' => $this));
		Hook::exec('actionObject'.get_class($this).'AddBefore', array('object' => $this));

		// Automatically fill dates
		if ($autodate && property_exists($this, 'date_add'))
			$this->date_add = date('Y-m-d H:i:s');
		if ($autodate && property_exists($this, 'date_upd'))
			$this->date_upd = date('Y-m-d H:i:s');

			
		if (Shop::isTableAssociated($this->def['table']))
		{
			$id_shop_list = Shop::getContextListShopID();
			if (count($this->id_shop_list) > 0)
				$id_shop_list = $this->id_shop_list;
		}
		
		// Database insertion
		if (Shop::checkIdShopDefault($this->def['table']))
			$this->id_shop_default = min($id_shop_list);
		if (!$result = ObjectModel::$db->insert($this->def['table'], $this->getFields(), $null_values))
			return false;

		// Get object id in database
		$this->id = ObjectModel::$db->Insert_ID();

		// Database insertion for multishop fields related to the object
		if (Shop::isTableAssociated($this->def['table']))
		{
			$fields = $this->getFieldsShop();
			$fields[$this->def['primary']] = (int)$this->id;

			foreach ($id_shop_list as $id_shop)
			{
				$fields['id_shop'] = (int)$id_shop;
				$result &= ObjectModel::$db->insert($this->def['table'].'_shop', $fields, $null_values);
			}
		}

		if (!$result)
			return false;

		// Database insertion for multilingual fields related to the object
		if (!empty($this->def['multilang']))
		{
			$fields = $this->getFieldsLang();
			if ($fields && is_array($fields))
			{
				$shops = Shop::getCompleteListOfShopsID();
				$asso = Shop::getAssoTable($this->def['table'].'_lang');
				foreach ($fields as $field)
				{
					foreach (array_keys($field) as $key)
						if (!Validate::isTableOrIdentifier($key))
							throw new PrestaShopException('key '.$key.' is not table or identifier, ');
					$field[$this->def['primary']] = (int)$this->id;

					if ($asso !== false && $asso['type'] == 'fk_shop')
					{
						foreach ($shops as $id_shop)
						{
							$field['id_shop'] = (int)$id_shop;
							$result &= ObjectModel::$db->insert($this->def['table'].'_lang', $field);
						}
					}
					else
						$result &= ObjectModel::$db->insert($this->def['table'].'_lang', $field);
				}
			}
		}

		// @hook actionObject*AddAfter
		Hook::exec('actionObjectAddAfter', array('object' => $this));
		Hook::exec('actionObject'.get_class($this).'AddAfter', array('object' => $this));

		return $result;
	}

if by hook is not working you mean that function does not fire after the event of actionObjectProductAddAfter, then the problem is that this event has not taken place at all.

Check the ObjectModel class and search for Hook::exec

You will see which hooks are there and when they get fired.

AddAfter and UpdateAfter are different.

The last thing is that, you mentioned you want to run some code or process some thing or any thing of that sort, JUST AFTER a combination is added. Read this again, a combination, so that will obviously not fire the ProductAddAfter at all.

You need to find out the object models that are involved in the action of adding a product combination. Then put your code in that hook method. Thats it. Good luck

Yeah I know, the weird thing is that now all the hooks fired, the same hooks I spent horus in the past days to get it work, and I did not change anyhting.
I am really curious if this was a server side issue (with the cache maybe) the server is not hosted by me and I do not have full acccess.

Either way, all hooks are firing properly now..

@stifler97 1 last question,

I fixed the code, and I am hooking into hookActionObjectCombinationAddAfter,

Where I execute this code:

    public function hookActionObjectCombinationAddAfter($params) {

        $language = Tools::getValue('language', 'ro');
        $language = Language::getIdByIso( $language );

        $product = new Product( $params['object']->id_product, false, $language);
        $combinations = $product->getAttributeCombinations(2);

        $newArr = [];

        foreach($combinations as $combination) {
            $attributeValues = $product->getAttributeCombinationsById($combination['id_product_attribute'], 2);
            $newArr[$combination['id_product_attribute']][] = $attributeValues;
        }

        echo "<pre>";
        print_r($newArr);
        echo "</pre>";
        die("exit");

    }

I expected the newsest combination added (the one with an ID of [2846]) to return the same values as the combination with the id of [5], but for some reason [attribute_name] is empty.
Is there another hook that gets executed after the hook I am using, and therfore the attribute_name is created after? I also tried hookActionObjectAttributeGroupAddAfter but it does not trigger.
