How to build HTML5 Shopping Cart app using Ionic Cordova : Part 4

This article will discuss on, how to  Implement a shopping cart app using html5 cordova.Here i will give you the basic overview on, how i implemented  product listing in my FoodKart App. Later in the Part 5 of this series, i will show, how the entire application was implemented.

If you find it difficult to follow, please go through my previous articles:

UPDATE (10-07-16):

Latest FoodKart V0.3 is released. Read the complete tutorial here.



  1. Variable names in java script can be used in HTML as {{ variable_name }}
  2. Populating a List is done is using ng-repeat
  3. ActionListener for HTML entities using ng-click
  4. Controllers is the place where you write action events.

LEVEL 1  [ Basic] :-

  1. The main part of building the Ionic Cordova App comes in modifying, the files in WWW directory.
    www directory files


  • JS contains the  Java script files i.e. the file responsible for actions.
  • Templates contains the html5 pages i.e. different screens of your App.
  • index.html :  is the main container used to display your pages.It will also contain elements that are shared throughout the app.
    For eg :- Navigation Bar, js files etc.
  • img is the place where you put the images associated with the app.
  • css is the place where you put the custom style files for your app.
  • lib is the place containing ionic library files.

3. We call the js variable in HTML using  {{ variable_name }}

4. To populate an list ionic :

<ion-list ng-repeat="item in menu_items">   // ng-repeat is similar to for-each loop
		<h2> {{ item.property_name }} </h2>

//menu_items is array of items (objects) declared in the respective controller.

5. To call an action listener in Ionic:  [ applicable to all HTML entity ]

<a ng-click="function_name(parameter1,parameter2 ....  )" > </a>

// ng-click is applicable on any clickable html entity


LEVEL 2  [ Intermediate: will be focusing on offline concepts ] :-

  1. Adding icon for Cart, Profile, Home in Navigation Bar.  [ shown as Section 1 in the image below ]

You can find the reference samples:


[color-box]  index.html [The container]  [/color-box]

 <body ng-app="app" animation="slide-left-right-ios7"> // The body tag
        <ion-nav-bar class="bar-positive" >     // The navigation bar container 
            <ion-nav-back-button   side="left" class="button-icon icon ion-arrow-left-c">  //Back arrow icon
			<ion-nav-buttons side="right"   >    // "right" aligned			
				<div ng-controller="indexCtrl">   // "indexCtrl" (\www\js\controllers.js) contains the action calls  
				    //icons for home , profile and cart
					<a href="#/page1" class="button  button-icon ion-android-home"></a>    
					<a href="#/page4" class="button  button-icon ion-android-person"></a>
					<a  href="#/page2" class="button  button-icon ion-android-cart" ></a>

        <ion-nav-view></ion-nav-view>   // container that shows the html pages in template folder [Reference 1]


2. Creating the menu page. [ Section 2 in the image ]

We have already created a basic list layout from How to design HTML5 app using Ionic Cordova : Part 2

We just need to add cart icon on every list item, and some basic formatting

[color-box]  templates\menu.html [Menu page i.e. Main page]  [/color-box]

<ion-view title="Menu">  // [Reference 1]
	// avoid padding to get the native feel.
	// Header section is used to show title for the page ie Menu, Product, Cart etc
    <ion-content padding="'false'" class="has-header">  
		// Search bar
        <form class="list">
            <label class="item item-input">
                <i class="icon ion-search placeholder-icon"></i>
                <input type="search" placeholder="">
	 //Sort bars
      <div class="button-bar">
            <a href="#/page6" class="button button-stable button-block  icon-left ion-android-funnel">Filter</a>
            <a href="#/page7" class="button button-stable button-block  icon ion-android-restaurant">Sort</a>
	// List	
        <ion-list ng-repeat="item in menu_items">  // ng-repeat is a loop ie  for-each(item in menu_items)

			// individual list item
			<ion-item class="item-thumbnail-left" >  // sets thumbnail to left
				  // <img> is used to show product image
			     // ng-src is similar to src in html. It is used to give the image location
				 // ng-click is similar to  onClickListener() . Here it trigers showProductInfo() function passing the respective item parameters.
                <img  ng-src="{{'img/'+ item.p_image_id +'.jpg'}}"  ng-click="showProductInfo(item.p_id,item.p_description,item.p_image_id,item.p_name,item.p_price)" >
				//used <p> to position cart icon to right 
				// Calling addToCart() function with parameters passed
				<p style="position:absolute;right:10px;">
				<a  ng-click="addToCart(item.p_id,item.p_image_id,item.p_name,item.p_price)" class="button  button-balanced button-clear   icon ion-android-cart">  </a> 
				//product name displayed using heading tag ie <h2>
				//Calling showProductInfo() function with parameters passed
				<h2  ng-click="showProductInfo(item.p_id,item.p_description,item.p_image_id,item.p_name,item.p_price)" > {{item.p_name}} </h2>
				//<p> is used to show product price
				//Calling showProductInfo() function with parameters passed
				<p   ng-click="showProductInfo(item.p_id,item.p_description,item.p_image_id,item.p_name,item.p_price)">Price: ${{item.p_price}}</p>


3. To implement listing of items from the server, we are basically parsing JSON response.

[color-box]  js\controllers.js [ ActionListener  ]  [/color-box]

.controller('menuCtrl', function($scope,$http) {
	//$scope.$on----> onload event
	$scope.$on('$stateChangeSuccess', function () {
		$http.get(str).    // sends request for the file
		success(           // if seccusfull response is recieved
			function (response){  // if response is not null 
				$scope.menu_items = response.records;   // set menu_items array with items from response
	}); // end of '$scope.$on'



$scope.$on(‘$stateChangeSuccess’, function () { . . . } is used to detect if the page url has changed.

It can also be used to detect if the controller page is active or not.



4. Now you might be thinking “How menuCtrl is linked with the menu page? ”

It is linked in the following file www\js\routes.js

    .state('menu', {
      url: '/page1',
      templateUrl: 'templates/menu.html',
      controller: 'menuCtrl'


5. In the server side we use PHP to output JSON response for listing the products.


// Used to output JSON data
header("Access-Control-Allow-Origin: *");   
header("Content-Type: application/json; charset=UTF-8");

//used to establish connection
$conn = new mysqli("localhost", "mysql username", "mysql password", "mysql database");

// query to retrieve the products
$query="SELECT p_id,p_name,p_description,p_image_id,p_price FROM products where p_available=1 ";

//generates the result
$result = $conn->query($query);
$outp = "";
while($rs = $result->fetch_array(MYSQLI_ASSOC)) {
    if ($outp != "") {$outp .= ",";}
    $outp .= '{"p_id":"'  . $rs["p_id"] . '",';
    $outp .= '"p_name":"'   . $rs["p_name"]        . '",';
	$outp .= '"p_description":"'   . $rs["p_description"]        . '",';
	$outp .= '"p_image_id":"'   . $rs["p_image_id"]        . '",';
	$outp .= '"p_price":"'. $rs["p_price"]     . '"}';
$outp ='{"records":['.$outp.']}';

//outputs the content


6. This is the MYSQL Table for Products

-- Table structure for table `products`

  `p_id` varchar(5) NOT NULL,
  `p_name` varchar(30) NOT NULL,
  `p_description` varchar(300) NOT NULL,
  `p_category` varchar(30) NOT NULL,
  `p_image_id` varchar(500) NOT NULL,
  `p_price` int(11) NOT NULL,
  `p_available` tinyint(1) NOT NULL,
  `p_stock` int(11) NOT NULL,
  PRIMARY KEY (`p_id`)

-- Dumping data for table `products`

INSERT INTO `products` (`p_id`, `p_name`, `p_description`, `p_category`, `p_image_id`, `p_price`, `p_available`, `p_stock`) VALUES
('1', 'Paneer Masala', 'Paneer Masala Description', '1', 'cv1wVOtRnmMJtzNlo4Ew_2', 20, 1, 100),
('2', 'Tandoori Chicken', 'Tandoori Description', '2', 'CARLvOcNTQmqVv42rhFz_1', 30, 1, 100),
('3', 'Gopi Manchurian', 'Gopi Description', '1', 'JhMIxzQXmB03SXPg84Iw_3', 20, 1, 100),
('4', 'Grilled Chicken', 'Grilled Chicken Description', '2', 'd5R11v9fRuvAx8wKYIWP_4', 40, 1, 100),
('5', 'Chana Masala', 'Chana Masala Description', '1', 'JhMIxzQXmB03SXPg84Iw_3', 10, 1, 100);

-- --------------------------------------------------------

7. Sample JSON Response.

         "p_name":"Paneer Masala",
         "p_description":"Paneer Masala Description",
         "p_name":"Tandoori Chicken",
         "p_description":"Tandoori Description",
         "p_name":"Gopi Manchurian",
         "p_description":"Gopi Description",
         "p_name":"Grilled Chicken",
         "p_description":"Grilled Chicken Description",
         "p_name":"Chana Masala",
         "p_description":"Chana Masala Description",
