angular.module('starter.controllers', [])
.controller('AppCtrl', function($scope, WC, $localStorage, $rootScope, $ionicModal, $state){
  
  $scope.$on('$ionicView.enter', function(e) {
    console.log("userData", $localStorage.userData);
    if($localStorage.userData){
      $rootScope.userData = $localStorage.userData
    }
  });
  
  $scope.logout = function(){
    $localStorage.userData = undefined;
    $rootScope.userData = undefined;
  }
  
  $localStorage.cart = [];
  
  if($localStorage.cart)
    $rootScope.cartCount = $localStorage.cart.length;
  else
    $rootScope.cartCount = 0;

.controller('ProductCtrl', function($scope, WC, $stateParams, $ionicSlideBoxDelegate, $localStorage, $rootScope){
  
  var Woocommerce = WC.WC();
  
  Woocommerce.get('products/' + $stateParams.productID, function(err, data, res){
    if(err)
      console.log(err);
      
    $scope.product = JSON.parse(res).product;
    $scope.images = JSON.parse(res).product.images;
    console.log($scope.product);
    $scope.$apply();
    
    $ionicSlideBoxDelegate.update();
    $ionicSlideBoxDelegate.loop(true);
    
    
    Woocommerce.get('products/' + $stateParams.productID + '/reviews', function(error, dat, response){
      if(error)
        console.log(error);
        
      $scope.reviews = JSON.parse(response).product_reviews;  
      
    })
    
  })
  
  $scope.addToCart = function(product){
    var countIncreased = false;
    $localStorage.cart.forEach(function(item, index){
      if(item.id == product.id && !countIncreased){
        console.log(item.id + "==" + product.id);
        item.count += 1;
        console.log("count increased by 1 for " + item.title);
        countIncreased = true;    
      }
    });
    
    if(!countIncreased){
      product.count = 1;
      $localStorage.cart.push(product);
    }
    $rootScope.cartCount = $localStorage.cart.length;
  }
  
  
});
