Username availability check using Codeigniter, AJAX and MySQL

This tutorial will show you how you can check username availability using Codeigniter, AJAX and MySQL. Sometimes we need to check username availability instantly before a user presses the submit button after filling a long-sized signup form. In this case we can use AJAX technique with any server side technologies like PHP, Codeigniter, Servlet, Struts, JSF, Spring etc. for checking whether the input username is avaialable for creating new user account or it has already been taken by someone else. So if we give instant result to the user for username availability then sometimes it makes more sensible than while pressing the submit button and goes top of the signup form to rectify the username input field if input username is not available. So after finishing this example “username check availability using Codeigniter, AJAX and MySQL” you will be able to apply the same logic to any server side technologies.

Multi-step Registration form using Codeigniter, MySQL, jQuery

Sometimes we need to capture lots of user details during registration process and as a result we got long forms on web page. So the best solution is to break the form into smaller logical section and present it into a multi-step registration form. This type of mult-step registration form always improves usability on web page comparing to very long form.

I am going to explain how to convert very long form into multi-step registration form using Codeigniter, MySQL and jQuery.

AngularJS Codeigniter REST CRUD Example

In this Codeigniter AngularJS CRUD example, we will see the integration of AngularJS with Codeigniter REST. We are going to create CRUD application using Codeigniter REST API on server side and AngularJS is encapsulated within PHP file on client side. Thus the client will communicate with server asynchronously using AngularJS $http service.

Introduction

The most important concept in REST is resources, which are identified by global IDs — typically using URIs. Client applications use HTTP methods (GET/ POST/ PUT/ DELETE) to manipulate the resource or collection of resources. A RESTful Web service is implemented using HTTP and the principles of REST. Typically, a RESTful Web service should define the following aspects:

The base/root URI for the Web service such as http://<host>/<appcontext/contextpath>/<url pattern>/<resources>.
The MIME type of the response data supported, which are JSON/XML/TEXT/HTML etc.
The set of operations supported by the service. (for example, POST, GET, PUT or DELETE). Continue reading “Working with RESTful services in Codeigniter – DELETE example”

Setup Codeigniter, Netbeans and XAMPP in Windows

This tutorial will show you how to configure Netbeans, Codeigniter, XAMPP together in Windows environment so that it would be easier environment to write PHP code on Netbeans editor without thinking much about the programming syntax error which is occurred most of the time when we write code in a notepad. It would be easier to run the Codeigniter application in browser when we use an IDE like Netbeans; we simply do right click on the project and click on Run to run the application on browser. We can also choose the preferred browser from the Browser Options in Netbeans. Continue reading “Setup Codeigniter, Netbeans and XAMPP in Windows”
