- Create View: Go to the application/views/ directory and create a view file (home_view.php) for Home controller. Open this home_view.php file and write some HTML code.DOCTYPE html> Welcome to My First CodeIgniter Application Welcome to My First CodeIgniter Application! If you would like to edit this page you'll find it located at: application/views/home_view.php The corresponding controller for this page is found at: application/controllers/Home.php
- Earlier a Home controller was created, open it again and create an index() method to adding logic to the controller. In the index() method, the view() function will be used to load view file (home_view.php).
Connect Database:
To connect and access the database, you need to configure your database by specifying the database hostname, username, password, and name in the application/config/database.php file. Open the application/config/database.php file and set the following values.
Create Model
Instead of writing database queries in the controller, it should be placed in a model. Models are the place where all the database related operations (retrieve, insert, update, delete, etc.) are done.
You can download the example CodeIgniter project which has created by following this tutorial. Only some minimal configuration needed to install this demo CodeIgniter application on your server. You only need to download the demo project from the source code link, extract the zip file and follow the instructions given in the ReadMe.txt file.
PHP especially needs to be installed and configured properly to work with CodeIgniter. Also, you need access to create a new database through MySQL or any other DB software. Familiarity with basic PHP syntax and experience setting up a web server will help with understanding the CodeIgniter configuration.
Alternatively, you can also download CodeIgniter by clicking on the GitHub link given on the website. This will take you to the CodeIgniter4 repository page. Here you can download the zip file for the latest commit.
Now we need to set up a web server that will serve our CodeIgniter application. For this guide, we will use Apache, but you can use any web server like Nginx instead. Here are the steps to set up an Apache web server:
That concludes the CodeIgniter installation tutorial! We downloaded the latest CodeIgniter, set up Apache web server, created a MySQL database, configured system paths and database credentials, set file permissions and tested the output. CodeIgniter is now ready for app development. With its simple syntax, rich set of libraries and clear documentation, you can build powerful PHP apps quickly using CodeIgniter.
This block of documentation presents step-by-step tutorials that focus heavily on fundamental and frequently encountered development questions and needs. It can serve beginners to get acquainted with the library and experienced users to quickly dive into the topic of interest.
Many users understand the simplicity of using grocery CRUD but after installing it they don't actually know where to start. In this tutorial we will try to cover the basic functionality of grocery CRUD and a step by step tutorial of how using it.
So we can copy it easily and have a starting point to use grocery CRUD. In our example we first have to see the CRUD is rendered without any problem with the default functionality. So when we will add those 4 simple lines of code at our project we will have a result that will look similar to this:
As we can easily see now ALL the "Record" strings are transformed to "Employees". So now for example we have: "Add Employee", "Edit Employee", "Delete Employee" , "Are you sure that you want to delete this Employee" and so on...
So with this line of code we will have only 4 columns at our list page and not all the columns of the table. The add and edit form they will still have all the fields of the table without any problem.

Hi, Welcome to our PHP CodeIgniter Tutorial Series. These step by step tutorials are intended for beginners who want to start learning php codeigniter from scratch. It will start right away from setting up the codeigniter framework working environment and move on to more advanced topics covering codeigniter framework libraries, helpers and active record class for database communication. Another nice perk with this series is you will get to know about the popular twitter bootstrap css framework while learning.
Twitter Bootstrap CSS is used in this tutorial series for designing the user interface for codeigniter application and there are some dedicated articles covering the usage of bootstrap framework with codeigniter application. But you are encouraged to write down your own style sheets if you prefer.
Using Twitter Bootstrap with CodeIgniter saves the hassle of writing CSS stylesheets of your own and lets you focus on development. Later you can customize bootstrap styles to suit your need. That is the best part of using MVC pattern as the presentation layer (i.e., view) is separate, you can change the look and feel of the app anytime without disturbing the rest of it.
PHP CodeIgniter Framework follows special url structure which is quite intriguing for newbies and this beginners tutorial will lay it out clearly for you to understand it better. By the end of this article you will have the codeigniter development environment up and ready. Read Complete Tutorial Here
So you are up and ready for the challenge? As we already know codeigniter follows MVC (Model-View-Controller) pattern and demands a structured workflow and unique url structure to access the files. In CodeIgniter, any web page be a static or dynamic one needs controller and view files and the model file is required only in case of database communication.
CodeIgniter is constantly upgrading to the industry changes and the older versions 2.x included database drivers like mysql, mysqli, pdo, postgre etc by default. But working with MSSQL Database Management system requires you to manually install the drivers but the latest codeigniter v3.0 includes mssql driver too.
