hookActionUpdateQuantity doesn't work

[java2dev]

hi, I have the presta hook hookActionUpdateQuantity with some codelines at the first I put an echo to see if the function executes but it doesn't print the echo. any idea?

include(dirname(__FILE__).'/sql/install.php');

        return parent::install() &&
            Configuration::updateValue('LIN_LAST_SYNC', date('c')) &&
            $this->registerHook('actionProductAttributeUpdate') &&
            $this->registerHook('actionUpdateQuantity');
....
public function hookActionUpdateQuantity($params)
    {

       echo 'test';

//My code

     }

It's possible the page is redirecting, which means you never see the output. Try adding die; after the echo statement. That will prevent the page redirecting.

[java2dev]

when I added die; and click on save I received a message error as in the picture "parser error: SyntaxError: Unexpected token e in JSON in position 1"

but I have put it more at the end

public function hookActionUpdateQuantity($params)
    {
        echo 'test1';
        echo $params;
        if ($params['id_product_attribute']) {
            echo 'test2';
            $idp = $params['id_product'];
            echo "el id_product is : $idp";
            $ida = $params['id_product_attribute'];
            echo "el id_product_attribute is : $ida";
            $api = new LinioApi();
            $pr = new LinioProduct($idp, false, Context::getContext()->language->id);
echo 'test3';
            $sku = $pr->getSku($ida);
            $xml = simplexml_load_string($api->getProductBySku(array($sku)));
echo 'test4';
            $qty = (int) $xml->Body->Products->Product->Quantity;
            $res = (int) $xml->Body->Products->Product->ReservedStock;
            $avl = StockAvailable::getQuantityAvailableByProduct($idp, $ida);
            echo 'test5';
            if (($qty - $res) < $avl) {
                echo 'test6';
                $api->updateProduct($pr->getXmlQty($ida));
                echo 'test7';
                die;
                echo 'test8';
            }
            echo 'test9';
        }
        echo 'test10';
    }

but I have printed test1Arraytest10test1Arraytest2el id_product is : 2el id_product_attribute is : 7test3test4test5test6test7

I've found where is the issue, in the hook function this line has his value always is NULL

$sku = $pr->getSku($ida);

the getSku function I have like this

public function getSku($attrib = 0)
    {
        return !$attrib ? $this->reference : $this->attributes[$attrib]['reference'];
    }

for the $ida and $idp they print the value without problem, the dump of $pr print a huge array with many product information and include the sku value I need to have in getSku.

Check to make sure $this->attributes has been set correctly with all the attributes.

[java2dev]

Yep, it's working, the "die" has help me to check the output, know it's working I had a problem in if condition at the top. I have a doubt as mentienned before I don't understand why there is a first hookaction (without loop) only test1 test10 and second time the function enter by the if $param.

 

another question

 

why I can't print id_product in this function (but it works for quantity hook)

public function hookActionProductAttributeUpdate($params)
    {
		//a verificar.
	if ($params['id_product_attribute']) {
			$idp = $params['id_product'];
			echo $idp;
			$ida = $params['id_product_attribute'];
			echo $ida;
			$api = new LinioApi();
			$pr = new LinioProduct($idp, false, Context::getContext()->language->id);
			$sku = $pr->getSku($ida);
			$xml = simplexml_load_string($api->getProductBySku(array($sku)));
			$api->updateProduct($pr->getXmlDesc($ida));
			
        }
		echo "test9";
		die;
		
    }

I want to update description for combination, upc, price, etc
