5 Easy Steps To Use WordPress Backend in Building PhoneGap APPs

Native mobile apps have their own advantages, but developing one can take a lot of time and investment. If you are not up for it, then go for cross-platform applications.

PhoneGap app is an open source software that allows developers to create cross mobile apps using HTML, CSS and JavaScript. It can reuse the same code and design for the cross platform applications and save a lot of time, resources, and investment.
PhoneGap is easy to manage and the JavaScript programming is lot easier than Java used for developing native Android apps.
WordPress is another great tool for developers, and when these two meet, magic happens!
In this post, we have shared how you can create a PhoneGap app with WordPress as the backend.
Before we go any further, let us know about NodeJS, as you will need it. NodeJS is a cross-platform runtime environment used for network application.

Step 1- The very first step is to define REST APIs to allow PhoneGap to connect with the WordPress. REST is the architecture style that guides web service creation which enables connection to the network. Whereas API is the set of program commands and protocols used to create and access the data or feature of an application. REST APIs can be useful for data downloading, uploading, among other functions that communicate with parse.

Step 2- WordPress has everything that is required to define REST APIs (readable by any HTTP client).  REST APIs can easily be integrated using a WP plugin. The ‘Already Logged in’ is by default executed as a user logs-in and an Ajax request from PhoneGap and a session cookie is sent to the server by default. In case there is no user login, Login function is executed. Then an HTTP request is sent, executing the REST API.

Step 3- Create GET/POST REST APIs using wp_ajax_ and wp_ajax_nopriv_ if the HTTP client that is making the request is already logged-in in WP and the callback attached to wp_ajax_ and wp_ajax_nopriv_ are processed.

Step 4- Directory structure, www directory, HTML file and a JavaScript file are created using a desktop builder tool. To allow users to interact and display graphics, UI is created with JQuery using Content Delivery Network (CDN). Pages should be created for users to login and see posts under the HTML file. JavaScript login function is executed when the login button is clicked.

Step 5- Under the JavaScript file, the code is written to add front-end functionality. The username and password credentials received during login are forwarded to WordPress for authentication. After authentication, WordPress sends back a session cookie to acknowledge user’s login. Then to display recent post, a fetch_and_display_posts function is used. Open_browser comes to play to open posts in a different browser window with PhoneGap InAppBrowser.

Additional tip- You can use a plugin like AppPresser to integrate PhoneGap API with WordPress.
