[11.x] TrimStrings: support nested attribute

[SocolaDaiCa]

protected $except = [
        'current_password',
        'password',
        'password_confirmation',
];

sometimes I send form request as

Create many users

[
	'users' => [
		[
			'email' => '',
			'password' => '',
		],
		[
			'email' => '',
			'password' => '',
		],
	],
],

or create company with a new admin

[
	'name' => '',
	'location' => '',
	'admin' => [
		'email' => '',
		'password' => '',
	],
],

I need define except like admin.password, users.0.password, users.1.password, .... , users.n.password. I cant define all of it

I think TrimStrings should support nested attribute, when define password it match *.password, *.*.password ... etc

my english is not good, sorry if i write curtly or hard to understand

Hi @driesvints , I had update explanation to this PR, please help me review It

[ntiyiso-rikhotso]

I think @SocolaDaiCa is trying to use the dot notation to exclude some array keys from being trimmed

e.g
Given the payload:

[
	'users' => [
		[
			'email' => '[email protected]',
			'password' => 'password#',
		],
		[
			'email' => '[email protected]',
			'password' => '/password',
		],
	],
],

He wants the possibility to exclude a password from being trimmed by adding it like

protected $except = [
        'users.*.password'
];

Apologies if I did not understand your pull request @SocolaDaiCa
