Modify input before validation on Laravel 5.1

Question

I\'m trying to modify an user submitted input before validation success. I\'ve followed this easy instructions, but when I test it on Laravel 5.1, It\'s not working.

Answer 1

These answers no longer work for me in 5.5

you can use

protected function validationData()
{
    $this->request->add([
        'SomeField' => '..some code to modify it goes here'
    ]);
    return $this->request->all();
}

the add method on request overwrites any existing input for that key.

You can see why this works in Illuminate\Foundation\Http\FormRequest, if you follow the trail

/**
 * Get data to be validated from the request.
 *
 * @return array
 */
protected function validationData()
{
    return $this->all();
}
