Validation before saving product

[Jibu]

I am using PS 1.7
Created new module for saving additional dimensions for a products.

https://prnt.sc/jgxgeh

public function hookDisplayAdminProductsExtra($params){              
   $id_product =0;
   if (isset($params['id_product']) && (int)$params['id_product']) {
       $id_product =(int)$params['id_product'];
    }
   
    $sql = 'SELECT * FROM '._DB_PREFIX_.'_dimensions WHERE id_product = '.$id_product;
    $dimensions = Db::getInstance()->ExecuteS($sql);

    $this->context->smarty->assign(array(
        'id_product' => $id_product,
        'dimensions' => $dimensions,
    ));
    return $this->display(__FILE__, 'views/templates/admin/form.tpl');
}
//Saving Data
public function hookActionProductUpdate($params){        
        $id_product =(int)$params['id_product'];
        $_asj_pkg_dim_width=Tools::getValue('asj_pkg_dim_width');
        $_asj_pkg_dim_height=Tools::getValue('asj_pkg_dim_height');
        $_asj_pkg_dim_depth=Tools::getValue('asj_pkg_dim_depth');
        $_asj_pkg_dim_weight=Tools::getValue('asj_pkg_dim_weight');                
        
        //Deleting old items
        Db::getInstance()->delete('products_package_dimensions', 'id_product ='.$id_product);
        
        //insert 
        Db::getInstance()->insert('products_package_dimensions', array(
            'id_product' => $id_product ,
            'width' =>$_asj_pkg_dim_width,
            'height'=>$_asj_pkg_dim_height,
            'depth'=>$_asj_pkg_dim_depth,
            'weight'=>$_asj_pkg_dim_weight,
        ));                
        
}

Its working fine.

Hi,

 

The validation is handled by  the function : hookActionProductUpdate($params)   use the Submit and stay button in the template.

this happens after saving product. How to validate before saving?

Hi,

The   validation  can  be   done  inside  the   function  with  an  if   condition.

That   part  is  PHP   not  related  to  PrestaShop  or   a  Hook.

So how to do it? Update the product again? I want to raise an error on some conditions when admin updates a product with some special features.

How   would  you  do  it  in  a  normal  PHP   code?

This  is  PHP    compentance   not  PrestaShop  familiarity .

public   function  verifyCondition($conditions){

$message='';

if($conditions=='Some  Data'){     
//   do  somehing
}
else{
    $message='Your  Alert message';
}

return  $message;

}

 

I found it working like this:

 

public function hookActionObjectProductUpdateBefore($params){
  $flag = false;

  //some calculation inverts this flag to true
  $flag = true;

  if($flag === true){
    throw new PrestaShopException('Custom error goes here');
    die;
  }
}
