Creating form arrays with Laravel 4 - arrays

Question

In Laravel 4 I can create text inputs with code like:
{{ Form::text('title', '', ['placeholder' => 'Ex. title', 'id' => 'title']) }}
This is very useful, because if other fields of my form fail validation, I can just do...
return Redirect::back()->withErrors($validator)->withInput(Input::all());
And when the form is shown again, the field title will conserve the value that was submitted before.
Good stuff.
Now here is my problem: What about input arrays?
I added the following input fields to my form:
<input type="text" name="option[]" />
<input type="text" name="option[]" />
<input type="text" name="option[]" />
<input type="text" name="option[]" />
And I submitted the form, knowing that would fail, to see if when the form appears again, the values on these fields still remained. Instead Laravel threw an exception.
ErrorException
htmlentities() expects parameter 1 to be string, array given
Even if I have just 1 option, it still gives me the same error:
{{ Form::text('option[]') }}
Now, I know that I could handle the filling of the array option manually, maybe like this:
$options = Input::get('option');
return Redirect::back()
->withErrors($validator)
->withInput(Input::except('option'))
->with('options', $options);
and then just looping through the $option array on the blade template.
Yes, that would probably work. But that is kinda hacky, and it still misses the powerful workflow of Laravel to autofill fields after failed submission, like I did back with title. So my question is:
Is there any built-in way in Laravel 4 to handle Input Arrays under these situations?

Answer 1

If you add an index to each input like:
{{ Form::text('option[1]') }} {{ Form::text('option[2]') }} it will work.
You can see how this works in vendor\laravel\framework\src\Illuminate\Html\FormBuilder.php in the function that creates the input
