Laravel "At Least One" Field Required Validation

So I have this form with these fields

{{ Form::open(array('url' => 'user', 'id' => 'user_create_form')) }}

<div class="form-input-element">
<label for="facebook_id">ID Facebook</label>
{{ Form::text('facebook_id', Input::old('facebook_id'), array('placeholder' => 'ID Facebook')) }}
</div>

<div class="form-input-element">
<label for="twitter_id">ID Twitter</label>
{{ Form::text('twitter_id', Input::old('twitter_id'), array('placeholder' => 'ID Twitter')) }}
</div>

<div class="form-input-element">
<label for="instagram_id">ID Instagram</label>
{{ Form::text('instagram_id', Input::old('instagram_id'), array('placeholder' => 'ID Instagram')) }}
</div>

{{ Form::close() }}


I'd like to tell Laravel that at least one of these fields is required. How do I do that using the Validator?

$rules = array(
'facebook_id' => 'required',
'twitter_id' => 'required',
'instagram_id' => 'required',
);
$validator = Validator::make(Input::all(), $rules);

Answer

Try checking out required_without_all:foo,bar,..., it looks like that should do it for you. To quote their documentation:

The field under validation must be present only when the all of the other specified fields are not present.


Example:

$rules = array(
    'facebook_id' => 'required_without_all:twitter_id,instagram_id',
    'twitter_id' => 'required_without_all:facebook_id,instagram_id',
    'instagram_id' => 'required_without_all:facebook_id,twitter_id',
);
$validator = Validator::make(Input::all(), $rules);
