Introduction

Hello, everyone! Welcome back to Online Web Tutor, presented by the Preferred IK Solutions team. I'm Sanjay and in this Second part of our video series, we'll be continuing our exploration of WordPress customization. If You're new to this Channel, please don't forget to subscribe and watch our previous video Sessions to catch up on what we've covered so far. In the last session, we discussed the concept of APIs, JSON data, and the REST API. Today, we'll be focusing on installing and utilizing the JSON API plugin to enhance our WordPress setup.

Installing the JSON API Plugin

To begin, let's dive into the installation process of the JSON API plugin. Follow these steps:

  1. Access your WordPress setup and navigate to the Plugin section.
  2. Click on "Add New" and search for the JSON API plugin.
  3. Install and activate the plugin.

Activating and Configuring the JSON API Plugin

Once the JSON API plugin is installed, we need to activate and configure it for our WordPress setup. Here's what you need to do:

  1. Go to the Settings section and click on the JSON API option.
  2. In the JSON API dashboard, you'll find various methods provided by the plugin, such as post, respond, visits, and code. These methods allow you to Interact with the JSON format of data and establish connectivity with your application.
  3. Activate the desired methods by clicking on the "Activate" button next to each method. For example, if you want to utilize the post method, activate it.

Retrieving Post Information using the JSON API

The JSON API plugin makes it easy to retrieve post information from your WordPress setup. Here's how you can do it:

  1. Access the API link for retrieving posts, usually in the format: [Your Site URL]/API/get-post.
  2. Copy the API link and open a JSON editor online.
  3. Paste the link into the JSON editor to retrieve the post information in the JSON format.

Creating a Post using the JSON API

With the JSON API plugin, you can also Create new posts directly through the plugin's API. Here are the steps:

  1. Use the post creation method provided by the JSON API, which requires a nonce value for security purposes.
  2. Generate a nonce value by including the controller and method sections. For example: controller=posts&method=create.
  3. Once you have the nonce value, append it to the API URL, along with the title and content of your post.
  4. Hit enter to create the post. You can refresh your WordPress setup to see the newly created post.

Updating and Deleting Posts using the JSON API

Apart from creating posts, the JSON API plugin also allows you to update and delete existing posts. Follow these steps:

  1. Retrieve the post ID you wish to update or delete.
  2. Use the respective API routes, such as [Your Site URL]/API/update-post for updating and [Your Site URL]/API/delete-post for deleting.
  3. Include the required parameters, such as the post ID, in the API URL.
  4. Hit enter to update or delete the post accordingly.

Understanding Nonce Values in the JSON API

Nonce values play a significant role in protecting your URLs and forms from misuse. The JSON API plugin provides a method called get-nonce to generate unique nonce values. Here's how you can create a nonce value:

  1. Access the get-nonce method within the JSON API available methods.
  2. Include the controller (controller=post) and the method (method=create) in the API URL.
  3. Hit enter to retrieve the nonce value.

Creating a PHP Application with JSON API Integration

In our upcoming video sessions, we'll build a simple PHP application that interacts with the JSON API plugin. We'll utilize the methods and routes provided by the plugin to create, update, and delete posts from within our application. Stay tuned for the step-by-step guide on integrating the JSON API into your own PHP application.

Conclusion
