$product_copy->isNewRecord = true;
$product_copy->id = null;
$product_copy->save();

after save product $product->save(); always return false, please help me to solve my problem , thank alot :)

Answer 1

You just need to copy attributes and that's it why are you assigning the $product_copy->isNewrecord and $product_copy->id=NULL;.

The only reason the record is not saved is due to the validation error before saving the record you can check for errors if not saved

Just use

$product_original = Product::findOne($id);
$product_copy = new Product();
$product_copy->attributes = $product_original->attributes;
if(!$product_copy->save()){
  //either print errors or redirect
  print_r($product_copy->getErrors());
}
