I have a php script which processes a form with a single input.
I want the value I send through input to be added to an existing value in database (mysql).
For example in database I have value = 10
When I type into the input 25 and submit the info. I want the value in database to be 35. I don't need any php code. I just want to know the correct mysql query
UPDATE value = value + $newvalue
something like this would be right ?
