The framework comes with a class to help you sanitize your inputs.

Get input data

The framework comes with an Input class that helps you retrieve form submitted data.

Get all submitted data

$data = Input::all();

This will return an array with all submitted data found in a request.

Get a specific data

$data = Input::get('name');

The code above returns the saved value for the name key.

Return a default value if no data found

$data = Input::get('name', 'Foo');

If no name value is found, the code returns the Foo value.

Validate

Validate single data

$data = Validator::single($data, ['num', 'min:3']);

Pass an array of validation rules as a second parameter.

Validate multiple data

$data = Validator::multiple(Input::all(), [
    'field-name' => ['alnum', 'min:5'],
    'email'      => ['email'],
    'age'        => ['num']
]);

Pass an array of validation rules as a second parameter where the key is the data field name and its value is an array of validation rules.

Rules parameters

Some rules accept extra parameters in order to validate your data. Simply add a colon after your rule followed by parameters separated by a comma.

$data = Validator::single($url, ['url:http, https']);

$data = Validator::single($age, ['num', 'min:1', 'max:2']);
