What is the reason for the error that occurs when the field is empty?

Question

MySQL

There is a field in the form priceHere is the handler I can not understand the error that occurs if the field is not filled.
$product->price = $request->getParam('price');

Invalid datetime format: 1366 Incorrect decimal value: '' for column `myshop`.`products`.`price` at row 1 (SQL: update `products` set `price` = where `id` = 61)

I would be grateful for help.

Answer 1

You can do this:

$product->price = (int) $request->getParam('price');
