How to write api in code igniter tutorial

And here you have it: By giving both the API developer and the client application the choice of data formats to use, the API is opened up to a much wider audience and can be used with more programming languages and systems.

Working with RESTful Services in CodeIgniter

Additionally, it seeks to put in practice some of the lessons learned in the previous article and assumes you already have CodeIgniter installed on your development environment and have configured it as described in the first tutorial. Another example would be a common workflow task where data from one request is used as parameters in another request.

The database requirements are as follows: They support URL based format switching in the form of. For example, sample code that returns a user profile could then construct a string to display information about the user, such as first name and last name. Next, you need the above mentioned method in the Model class to read the information from your database table: If nothing is found, return no body and a to say nothing was found.

So the two examples we looked at before had a Resource of user and users. Now you may ask, why use 3 files and all these functions and configuration for this?

You cannot possibly provide sample code in all languages that can make HTTP requests, so what should you do? To load it, paste the following function into the class: If you can, get someone outside of your organization or company to write the sample code.

REST is all about Resources and they are essentially a noun within your application, which are interacted with i.

CodeIgniter Tutorial

This tutorial will show you how to use this code to set up your REST API, and gives example of how to interact with it from your web application. Use Hard-Coded Values Every programmer knows not to use hard-coded values in code. Assumptions You have a web server set up, locally or online and known how to manage files on it.

Save the file and point your browser to the Controller you just created: You may be surprised to hear that you should use hard-coded values in sample code. The first URL is a very simple one. This is a reserved parameter that will modify the output format of the requested data like so: At the end of the URL is the "format" parameter.

Object-oriented code tends to distribute the relevant information among various classes. In general, you should have a line of comment for at least every five or 10 lines of code.

Exceptions should be made for API keys and access tokens, which are expected to be different for each developer using the API. Focus on as many of those languages as you have the budget for.

So instead of simply using: Save the file and exit. If you wish to have a protected API which anyone could get at, use digest. This is prossibly the most confusing part of the tutorial if you are used to how CodeIgniter works. Having sample code that does only that is not especially useful.

You may be surprised to learn, therefore, that it is generally not desirable to create your own classes for sample code. Developers rate working sample code high on API documentation priority lists. Normally in CodeIgniter, you just pass in parameter values, but a REST controller accepts any number of parameters in any order.

Note that you do not need to include the php extension when loading it there. And the best sample code is written by a developer from outside the group that created the API.

All you have to do is load the database class in the constructor function if you have not autoloaded it already in the autoload.This tutorial will show you how to use this code to set up your REST API, and gives example of how to interact with it from your web application.

Assumptions You have a web server set up, locally or online and known how to manage files on it. Introduction. CodeIgniter is a powerful PHP framework that can help you greatly speed up the development of your web applications. It is has a small performance footprint due to the modular approach to loading its libraries and does a great job separating logic from presentation by using a Model-View-Controller (MVC) dynamic.

CodeIgniter Tutorial PDF Version Quick Guide Resources Job Search Discussion CodeIgniter is a powerful PHP framework with a very small footprint, built for developers who need a simple and elegant toolkit to create full-featured web applications.

This CodeIgniter tutorial will discuss how to create REST API from both server and client side. CodeIgniter has several libraries that support and easy to create REST APIs application. Currently, REST API becomes a communication method that must be used for web-based applications.

In this tutorial, you will be creating a basic news application. You will begin by writing the code that can load static pages. Next, you will create a news section that reads news items from a database.

Finally, you’ll add a form to create news items in the database. Hey Matthew thanks for the comment. I had suspected after taking a quick glance at the nettuts+ tutorial that there was probably an easier way to implement a RESTful API than the method outlined with codeigniter.
