Passing sometimes existing and sometimes non exsisting input
Closed this issue · 1 comments
I have a checkbox that only exists in my post values when it's checked. When not checked, the value doesn't exist in Input::all()
resulting in a InvalidArgumentException
when mapping the input to the command. I toughed to be smart and gave the parameter a default value of null
, this way the command executes when the checkbox is not checked, but when it's checked the value stays null
. After reading theCommanderTraid::mapInputToCommand
method I realised that it's coded in this way.
Though, I'm curious what people think of an approach where, when you don't always have the input available, you can give a default vale of null
and make a check inside mapInputToCommand
to see if the default value of the parameter is different to the value of the input from the same key. And if that's the case, assign the input value instead of the default value.
Never mind, this behaviour was part of my own code, CommanderTraid::mapInputToCommand
already behaves as described above.
