The default value of a request parameter doesn't work in laravel5.5

[argb]

• Laravel Version: 5.5.*
• PHP Version:7.1.2
• Database Driver & Version:

Description:

The default value of a request parameter doesn't work in laravel5.5 Such as the most simple code in any controller. dd($request->input('nickname', 'ddd'));

Obviously we supposed to get the default value ddd if the nickname is empty, but unfortunately we will dump a null value. Is laravel5.5 tested fully before release?

Steps To Reproduce:

How is that obvious? You have specified a value, it just happens to be null. (It was probably an empty string that a middleware changed into null.) Are you looking for $request->input('nickname') ?? 'ddd'?

So a little more detail would help. If memory serves, empty strings and null are perfectly acceptable values in this situation, so if the key exists and has a value of null or empty string, then that is what you receive, not the default. The default is in case the attribute doesn't exist at all in the given data.

@sisve @devcircus Thank you both, maybe I misunderstanding what the "DEFAULT" means, I thought it as default while i got an empty value, which include unsetted field, null, and empty string. Now i got it. Here the default value is triggered only while there are no the corresponding fields.
