php - Laravel 4 : Best Practice to Trim Input before Validation -

now, trim each input separately below code:

$username = trim(input::get('username')); $password = trim(input::get('password')); $email    = trim(input::get('email'));  $validator = validator::make(array('username' => $username,                                     'password' => $password,                                     'email'    => $email),                               array('username' => 'required|min:6',                                     'password' => 'required|min:6',                                     'email'    => 'email')); 

is approach trim @ same time with

input::all() or input::only('username', 'password', 'email')?

and best practice this?

note: solution won't work if of inputs arrays (such "data[]").

you may try this, trim using 1 line of code before validation:

input::merge(array_map('trim', input::all())); 

now rest of coding

$username = input::get('username'); // it's trimed  // ... validator::make(...); 

if want exclude inputs trimming may use following instead if all()

input::except('password'); 

or may use

input::only(array('username')); 

update: since laravel 5.4.* inputs trimmed because of new trimstringsmiddleware. so, no need worry because middleware executes on every request , handles array inputs well.
