how to validate data in hook product update in prestashop

[NishantVadgama]

hello 

I have successfully created new tab in admin with hookDisplayAdminProductsExtra() but when save data with hookActionProductUpdate() save as well but I want to validate before save data and give return back error if exits but I cant return error. It will directly save data.. if I post wrong data then it will give sql error but not mine. I have validate as follows.

public function hookActionProductUpdate()

{

    if (Tools::getValue('id_test'))

    {

          if(!Validate::isInt(Tools::getValue('id_test')))

          {

               $this->context->controller->_errors[] = Tools::displayError('Please enter valid data.');

          }

          if(!count($this->context->controller->_errors))

          {

               someObj = newObj();

               someObj.saveData(Tools::getValue('id_test'));

          }

    }

}

try adding echo 'got value' and so on  to check that all the if's are executed.

Just so we can confirm that.

 

and to a print_r of _errors before you check the count on it.

I have found problem solved the problem is only in "_errors" inspite of that just have to write "errors".

thank You
