Saving a checkbox

In my page I have 6 checkboxes and I would like the user to be able to select 1 or more checkboxes.

I have the checkboxes showing the correct values but I'm having a problem saving them. It's probably something small.

My BannersController.php

public function create()
    {
        $banners = Banner::with('frame')->get();
        $frame_options = Frame::lists('title', 'id');
        $menu_options = Menu::lists('title', 'id');
        return View::make('banners::banners.create', compact('banners', 'frame_options', 'menu_options'))->with($frame_options, $menu_options);
        //return View::make('banners::banners.create');
    }

    /**
     * Store a newly created resource in storage.
     * POST /bannerss
     *
     * @return Response
     */
    public function store()
    {
        $input = Input::all();
        $validation = Validator::make($input, Banner::$rules);

        if($validation->fails()){
            return Redirect::route('banners::banners.index')
                ->withInput()
                ->withErrors($validation)
                ->with('message', 'There were validation errors');
        }

        if($validation->passes()){

            $banners = new Banner();

            $frameId = (array) array_get($input, 'frame_id');
            $menuId = (array) array_get($input, 'menu_id');

            $banners->fill($input)->save();
            $banners->frame()->sync($frameId);
            $banners->menu()->sync($menuId);

            $banners = Banner::all();
            return View::make('banners::banners.index', compact('banners'));
        }
    }

My Banner.php

<?php

class Banner extends \Eloquent {
    protected $fillable = array('title');
    protected $guarded = array('id');

    protected $table = 'banners';

    public static $rules = array(

        );

    public function frame(){
        return $this->belongsToMany('Frame', 'banners_frame', 'banner_id', 'frame_id');
    }

    public function menu(){
        return $this->belongsToMany('Menu', 'banners_menu', 'banner_id', 'menu_id');
    }
}

My Menu.php

<?php
use Illuminate\Auth\UserTrait;
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

class Menu extends \Eloquent implements UserInterface, RemindableInterface{
    use UserTrait, RemindableTrait;

    protected $fillable = array('title', 'parent');
    protected $guarded = array('id');

    protected $table = 'menus';

    public static $rules = array(
            'title' => 'required'
        );

    public function parents(){
        return $this->hasMany('Parents');
    }

    public function content(){
        return $this->belongsToMany('Content', 'content_menu', 'menu_id', 'content_id');
    }

    public function banner(){
        return $this->belongsToMany('Banner', 'banner_menu', 'menu_id', 'banner_id');
    }
}

My create.blade.php

@extends('templates::admin')
@section('content')
