Laravel "At Least One" Field Required Validation

Question

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 1

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);
