I completely understand your anxiety when starting learn...

I completely understand your anxiety when starting learn codeigniter.

Confused, what have to know, and don't know start from where.

The good news,

In this tutorial, I will share with you how to start learning codeigniter from the scratch.

Step by step.

if you beginner. You will love this tutorial.

Let’s dive right in.

1. Overview

Codeigniter is a Web Application Framework (WAF) designed specifically to

facilitate web developers in developing web-based applications.

Codeigniter contains a collection of code in the form of libraries and tools

combined into a framework.

Codeigniter is a web framework for the PHP programming language designed by

Rick Ellis in 2006, founder of EllisLab.

Ellislab is a working team founded in 2002 and is engaged in software development

and tools for web developers.

Since 2014 until now, EllisLab has awarded codeigniter ownership rights to the British

Columbia Institute of Technology (BCIT) for further development process.

Codeigniter has many features (facilities) that help PHP developers to be able to

make web applications easily and quickly.

Codeigniter has a simpler design and flexible.

Codeigniter allows web developers to use the framework partially or as a whole.

It's means that codeigniter still gives freedom to the developer to write certain parts

of the code inside the app using the conventional way.

Codeigniter use the Model-View-Controller (MVC) design or architecture pattern

that separates the code portion for business process handling with code sections for

presentation purposes.

By using this design pattern, it allows web development to work on web-based

applications together (teamwork).

That way the web developers are more focused on their respective parts without

disturbing the other part.

So that the built application will be completed faster.

2. Codeigniter Advantages

Codeigniter is a toolkit devoted to you who want to build web based applications in

PHP programming language.

The advantages offered by codeigniter are as follows:

1. Codeigniter is an open-source PHP framework.

2. Codeigniter has a small size compared to other frameworks. After the

installation process, the Codeigniter framework is only about 2 MB.

3. Applications created using codeigniter can run fast.

4. Codeigniter uses a Model-View-Controller (MVC) design pattern so that one file

does not contain too much code. This makes the code easier to read,

understand, and maintain later on.

5. Codeigniter can be expanded as needed.

6. Codeigniter well-documented information about libraries and functions

provided by codeigniter can be obtained through the documentation

included in the distribution package.

7. Codeigniter has a complete library and helper.

8. Codeigniter has reliable security such as xss filtering, session encryption, and

others.

9. Codeigniter allows web developers to use libraries or helper not provided by

codeigniter like: Google Map API, Facebook API, fpdf, and others.

10. Codeigniter is flexible. So that giving freedom to web developers to develop

web-based applications even without framework.

11. Codeigniter has a large community and spread all over the world, making it

easier for web developers to solve problems faced by web developers in

developing web-based applications.

12. Codeigniter support many RDBMS (Relational Database Management System)

like MySQL, SQL Server, Oracle, Maria DB, PostgreSQL, SQLite, and others.

13. Codeigniter basically embraces Clean URL and supports SEO (Search Engine

Optimazation). So that, the application built using codeigniter is easier to index

by popular search engines like google, yahoo, msn, and others.

3. Model-View-Controller (MVC)

As I mentioned earlier that the codeigniter adopts the Model-View-Controller (MVC)

architecture.

So, It is very important for you to know the concept of MVC.

What is Model-View-Controller (MVC)?

MVC is a method to separate applications into three parts. Model, View, and

Controller.

MVC making the structure to the application, so it can achieve "code reusability".

Here is an explanation about MVC:

1. Model

Models represent data that applications use, such as databases, RSS, or data

obtained from API calls, and actions that involve the Create, Read, Update, and

Delete operations.

2. View

View is the information displayed to the user through the browser. Usually in the form

of HTML file or PHP code that compile template for a website.

In the codeigniter, the view can be parts of a page, template, or other types of

pages or templates.

3. Controller

Controller is a "business logic" that served as a bridge between the model and view.

The controller will respond to HTTP requests coming from the user (via browser), from

this request the controller will determine what to do.

In the codeigniter, in detail MVC is described as follows:

In the picture above, the file "index.php" acts as the main controller that invokes the

basic functions used to run the controller.

The router checks the HTTP request and then decides which Controller will be used to

handle the request.

If the cache file is available, the application flow will be skipped and the cache file

will be sent to the user's browser.

Before the controller is invoked, HTTP requests and user-submitted data will be first

sorted for security reasons.

The controller calls the Model, Library, Helper, and other files needed to handle HTTP

requests.

The end result will be displayed by the View file then sent to the user's browser to

display.

If caching mode is enabled, the results of the view will be cached first.

So if later there is the same request, can be directly used.

4. Installing Codeigniter

Codeigniter is a PHP framework that the simplest way of installing than any other PHP

framework.

You just need to extract it to your web server and install complete.

Easy right?

If you want to install codeigniter on localhost, there are some software that you can

use.

Among the most popular are WAMPSERVER, MAMP, or XAMPP.

You can choose one of them.

Here I use WAMPSERVER, if you also use wampserver you will love this article.

But, if you use XAMPP.

No Problem,

Because I will show how to install on WAMP and XAMPP.

Alright, to install codeigniter. you can follow these steps below:

1. Make sure Web Server is installed and running on your computer.

2. Download codeigniter file on the official website: www.codeigniter.com

3. Extract Codeigniter.zip to directory C:/wamp/www/ (if you use wampserver). But,

if you use XAMPP. Extract Codeigniter.zip to directory C:/xampp/htdocs/.

4. Go to C:/wamp/www/ (If you using WAMP) and rename codeigniter folder you

just extract to be your project name.

For example, here I rename to be "myproject". So it looks like the picture below:

5. Next, open your browser. here I use Mozilla Firefox. Then visit the URL below:

http://localhost/myproject/

If the installation is successful, it will look like the picture below:

5. Codeigniter Basic Configuration

In starting the codeigniter, there are some basic configurations you need to know.

That is autoload.php, config.php, and database.php.

All configurations on codeigniter, located in one place that is inside the folder

application/config.

How and what needs to be configured in autoload.php, config.php, and

database.php files?

Here's the explanation.

1. Autoload.php

Autoload.php, this file is used to set the functions that will be automatically loaded at

the beginning when the program is run.

To configure the autoload.php file, please open the folder:

application/config/autoload.php

like the picture below:

There are several things that can be loaded automatically include: packages,

libraries, drivers, helper files, custom config files, language files, and models.

For basic configuration you need to know are libraries and helper files.

It aims to have certain libraries and helper run automatically.

To configure the libraries, open the autoload.php file with a text editor such as

notepad ++, sublime text, or others.

And then find the code below:

$autoload['libraries'] = array();

Set to be like this:

$autoload['libraries'] = array('database');

In the above code, it means we load the library "database" automatically.

Thus you can use database functions on codeigniter.

Like function: Query Builder Class

Next, to configure the helper files, open the autoload.php file with the text editor.


$autoload['helper'] = array();

And set to be like this:

$autoload['helper'] = array('url');

In the above code, it means we load the "url" helper automatically.

Thus you can use the url functions on the codeigniter.

Like function: base_url (), site_url (), URI Segment, and others.

2. Config.php

In this file there are some configurations that have been configured by default.

But there are several configurations that need to be considered that is:

$config['base_url'] $config['index_page'] $config['encryption_key']

For basic configuration, you just need to know the base_url configuration

Base_url is the basic url of your project.

To configure base_url, open the config.php file with a text editor.


$config['base_url'] = '';


$config['base_url'] = 'http://localhost/myproject/';

3. Database.php

Judging from the name of file then you can already capture what the function of

this file.

The database.php file is used to configure the database configuration of the

website to be created.

The configuration to note are: hostname, username, password, and database.

To configure database.php. Open the database.php file with a text editor.


$active_group = 'default';

$query_builder = TRUE;

$db['default'] = array(

'dsn' => '',

'hostname' => 'localhost',

'username' => '',

'password' => '',

'database' => '',

'dbdriver' => 'mysqli',

'dbprefix' => '',

'pconnect' => FALSE,

'db_debug' => (ENVIRONMENT !== 'production'),

'cache_on' => FALSE,

'cachedir' => '',

'char_set' => 'utf8',

'dbcollat' => 'utf8_general_ci',

'swap_pre' => '',

'encrypt' => FALSE,

'compress' => FALSE,

'stricton' => FALSE,

'failover' => array(),

'save_queries' => TRUE

);





'dsn' => '',

'hostname' => 'localhost', // Hostname

'username' => 'root', // Username

'password' => '', // password

'database' => 'database_name', //database name


'dbprefix' => '',




'cachedir' => '',



'swap_pre' => '',

'encrypt' => FALSE,





);

6. Hello World Codeigniter

If you are serious with codeigniter, you should understand how a controller works.

For more details, I am going to share a simple case so you can understand how the

controller works.

Here I raised the case that is how to display text "Hello World" in browser using

controller.


Create a controller named Hello.php like the following picture:

Then type the code below:

<?php

class Hello extends CI_Controller{

function index(){

echo "Hello World";

}

}

Note: Every writing of filenames and class names is always preceded by Capital

letters.

After that save and open your browser, then visit the following url:

http://localhost/myproject/index.php/hello

Then will be seen text "Hello World" in your browser as follows:

If you look carefully, basically the url on the codeigniter looks like the following

picture:

Where, there are protocol, primary domain, index.php, class name, and function

name.

It may sound complicated, but it is not.

For more details please add one more function to Controller Hello.php. here I give

the name "show".

So the Hello.php controller becomes as follows:

<?php

class Hello extends CI_Controller{

function index(){

echo "Hello World";

}

function show(){

echo "I Make The World Better Place.";

}

}

If you run it by visiting the following URL:

http://localhost/myproject/index.php/hello/show

Then, will appear the result as follows:

7. Remove index.php from URL

Codeigniter is a php framework that supports clean URLs.

That way, you can create an easy-to-read and SEO Friendly URL.

In the "Hello World" application URL above, it can be seen that the index.php in the

url looks annoying.

Is there a way to remove index.php from URL?

Of course, you can use the .htaccess file to remove it.

How to create .htaccess file?

Let’s begin.

Create a file named .htaccess on your web root and type the code below:

RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L]

Just like the picture below:

Then open the application/config/config.php folder using the text editor.


$config['index_page'] = 'index.php';


$config['index_page'] = '';

Now please visit the following url for testing:

http://localhost/myproject/hello/show

Then the results will look like the picture below:

In the picture above, it can be seen that the URL becomes more neat and SEO

friendly by removing the index.php on the URL.

8. Controller and View

In the previous case, you already know how to display the text "Hello World" directly

from the controller.

But, it should be done in view.

Now, I will show how to display view from controller.

Let’s begin.

First of all, create a file in the application/controller with the name Blog.php.

Then type the following code:

<?php

class Blog extends CI_Controller

{

function __construct()

{

parent::__construct();

}

function index(){

$this->load->view('blog_view');

}

}

Second of all, create a file in application/views with the name of blog_view.php.

Then type the following code:

<!DOCTYPE html>

<html lang="en">

<head>

<meta charset="utf-8">

<title>My Blog</title>

</head>

<body>

<h1>Welcome To My Blog.</h1>

</body>

</html>

Then, open your browser and access the Blog controller.

Then the results will look like the following:

You can also send parameters to view via controller.

For example, please edit the Blog.php controller to be as follows:

<?php

class Blog extends CI_Controller

{

function __construct()

{


}

function index(){

$data['title'] = "This Is Title";

$data['content'] = "This Is The Contents";

$this->load->view('blog_view',$data);

}

}

Then edit the view blog_view.php be like the following:

<!DOCTYPE html>

<html lang="en">

<head>


<title><?php echo $title;?></title>

</head>

<body>

<h1><?php echo $content;?></h1>

</body>

</html>

Then, open your browser and access the Blog controller again. Then the results will

look like the following:

I hope you can understand the difference.

9. Codeigniter and Bootstrap

In the previous case, you have understood how to call view via controller.

Now, there is a very important thing for you to know, that is about combine

codeigniter with bootstrap.

What is BOOTSTRAP?

Bootstrap is an open source toolkit to be developed with HTML, CSS, and JS.

In other words, Bootstrap is a framework to beautify the user interface (UI).

Bootstrap is responsive.

In other words, renders well on various devices (platforms) such as tablets or mobile

phones.

Awesome right?

So, How to combine codeigniter and bootstrap?

Let’s begin.

First of all, please download the bootstrap on the official website getbootstrap.com.

Second of all, create a new folder on your project (webroot).

Here I named "assets" folder.

And then, extract the bootstrap file you have downloaded earlier into the assets

folder.

Like this:

Besides the bootstrap, we also need jquery for javascript on bootstrap to run

optimally.

To download Jquery, please download from the official website jquery.com.

And then, put the jquery file into assets/js/ folder.

Like the picture below:

It may sound complicated, but it is not.

So that you can understand what bootstrap looks like, please edit the view file

blog_view.php to be as follows:

<!DOCTYPE html>

<html lang="en">

<head>





<link href="<?php echo base_url('assets/css/bootstrap.min.css');?>" rel="stylesheet">

</head>

<body>

<div class="container">

<div class="jumbotron jumbotron-fluid">


<h1 class="display-4"><?php echo $content;?></h1>

<p class="lead">This is my first blog.</p>

</div>

</div>

</div>



<script src="<?php echo base_url('assets/js/jquery.min.js');?>"></script>



<script src="<?php echo base_url('assets/js/bootstrap.min.js');?>"></script>

</body>

</html>

If you call the blog controller in the browser, it will look like the following results:

In the picture above, you can see that we don't need to create css code to provide

a style on a website page.

Similarly, if you need a beautiful table. You also do not need to type css code to

give a style to the table.

Instead, you can instantly have a beautiful table instantly.

For example, please edit the view file “blog_view.php” to be as follows:

<!DOCTYPE html>

<html lang="en">

<head>





</head>

<body>


<h1><?php echo $content;?></h1>

<table class="table table-striped">

<thead>

<tr>

<th scope="col">#</th>

<th scope="col">First</th>

<th scope="col">Last</th>

<th scope="col">Handle</th>

</tr>

</thead>

<tbody>

<tr>

<th scope="row">1</th>

<td>Mark</td>

<td>Otto</td>

<td>@mdo</td>

</tr>

<tr>


<td>Jacob</td>

<td>Thornton</td>

<td>@fat</td>

</tr>

<tr>


<td>Larry</td>

<td>the Bird</td>

<td>@twitter</td>

</tr>

</tbody>

</table>

</div>





</body>

</html>

If you re-run the Blog controller in the browser, then you will get the following results:

Awesome right?

Hopefully, you could understand so far.

10. Work with Database

In this segment, you will learn all the things you need to know about how to interact

with the database using codeigniter.

Starting from Create, Read, Update, and Delete.


1. Database Preparation.

First of all, create a database. Here I created a database named "pos_db".

If you create a database with the same name, it's better.

To create a database, you can execute the query below:

CREATE DATABASE pos_db;

That query will create a database named "pos_db".

And then, create a table “product” with the structure below:

You can execute the query below to generate a table with the structure as above:

CREATE TABLE product(

product_id INT PRIMARY KEY AUTO_INCREMENT,

product_name VARCHAR(100),

product_price INT

);

Then input some data into the "product" table by executing the following query:

INSERT INTO product(product_name,product_price) VALUES

('Coca Cola','5000'),

('Teh Botol','3700'),

('You C 1000','6300'),

('Ponds Men','18000'),

('Rexona Men','13000');

The next step is to connect the codeigniter with the database.

To connect codeigniter with database is very simple, please open

application/config/database.php

Open the database.php file with a text editor and find the following code:




'dsn' => '',


'username' => '',

'password' => '',

'database' => '',


'dbprefix' => '',




'cachedir' => '',



'swap_pre' => '',

'encrypt' => FALSE,





);

And then set to be like this:




'dsn' => '',


'username' => 'root',

'password' => '',

'database' => 'pos_db',


'dbprefix' => '',




'cachedir' => '',



'swap_pre' => '',

'encrypt' => FALSE,





);

Please run your project again in browser, if no error means connection to database

successfully.

2. Display data from database to view (Read).

In this segment, I will show you how to display data from database to view.

Let’s begin.

#1. Create a file into application/models. Here I named “Product_model.php”.

So look like the picture below:

Open “Product_model.php” by using text editor. And then type the code below:

<?php

class Product_model extends CI_Model{

function get_product(){

$result = $this->db->get('product');

return $result;

}

}

#2. Create a file into application/controllers. Here I named “Product.php”.


Open the controller “Product.php” by using text editor. And then type the code

below:

<?php

class Product extends CI_Controller{

function __construct(){


$this->load->model('product_model');

}

function index(){

$data['product'] = $this->product_model->get_product();

$this->load->view('product_view',$data);

}

}

#3. Create a view file with the name “product_view.php”.


And then type the code below:

<!DOCTYPE html>

<html lang="en">

<head>


<title>Product List</title>



</head>

<body>


<h1><center>Product List</center></h1>


<thead>

<tr>


<th scope="col">Product Name</th>

<th scope="col">Price</th>

</tr>

</thead>

<?php

$count = 0;

foreach ($product->result() as $row) :

$count++;

?>

<tr>

<th scope="row"><?php echo $count;?></th>

<td><?php echo $row->product_name;?></td>

<td><?php echo number_format($row->product_price);?></td>

</tr>

<?php endforeach;?>

</tbody>

</table>

</div>





</body>

</html>

Then, run the "Product" controller through your browser, by visiting the following url:

http://localhost/myproject/product


3. Insert data to database (Create).

In this segment, I will show you how to insert the data into the database.

Let’s begin.

#1. Open the model "Product_model.php" file. then add one more function like this:

<?php




return $result;

}

function save($product_name,$product_price){

$data = array(

'product_name' => $product_name,

'product_price' => $product_price

);

$this->db->insert('product',$data);

}

}

#2. Open the controller "Product.php" file. then add some more functions like this:

<?php





}

function index(){



}

function add_new(){

$this->load->view('add_product_view');

}

function save(){

$product_name = $this->input->post('product_name');

$product_price = $this->input->post('product_price');

$this->product_model->save($product_name,$product_price);

redirect('product');

}

}

#3. Create a new view file with the name "add_product_view.php". With code like

the following:

<!DOCTYPE html>

<html lang="en">

<head>


<title>Add New Product</title>



</head>

<body>


<h1><center>Add New Product</center></h1>

<div class="col-md-6 offset-md-3">

<form action="<?php echo site_url('product/save');?>" method="post">

<div class="form-group">

<label>Product Name</label>

<input type="text" class="form-control" name="product_name" placeholder="Product Name">

</div>


<label>Price</label>

<input type="text" class="form-control" name="product_price" placeholder="Price">

</div>

<button type="submit" class="btn btn-primary">Submit</button>

</form>

</div>

</div>





</body>

</html>

Then, go back to the browser and type in the following url on your browser:

http://localhost/myproject/product/add_new


Enter product name and price in textbox, then click submit button.

Then the data will appear on the product list as follows:

4. Delete data to database (Delete).

In this segment, I will show you how to delete data to the database.

Let’s begin.

#1. Open the view file "product_view.php". Edit then edit to be like this:

<!DOCTYPE html>

<html lang="en">

<head>





</head>

<body>




<thead>

<tr>




<th width="200">Action</th>

</tr>

</thead>

<?php

$count = 0;


$count++;

?>

<tr>




<td>

<a href="<?php echo site_url('product/delete/'.$row->product_id);?>" class="btn btn-sm btn-danger">Delete</a>

<td>

</tr>

<?php endforeach;?>

</tbody>

</table>

</div>





</body>

</html>

In the "product_view.php" file above we add one more column to the product list

table. That is the action column.

In the action column there is a delete button. So if you run Controller product, by

visiting the following url:

http://localhost/myproject/product/


#2. Add a delete function to the Product.php controller.


function delete(){

$product_id = $this->uri->segment(3);

$this->product_model->delete($product_id);


}

So look full code from the controller Product.php below:

<?php





}

function index(){



}

function add_new(){


}

function save(){





}

function delete(){




}

}

#3. Add a delete function in Product_model.php model.

The code as follows:

function delete($product_id){

$this->db->where('product_id', $product_id);

$this->db->delete('product');

}

So look complete code from model Product_model.php below:

<?php




return $result;

}


$data = array(



);


}




}

}

Now go back to the browser and visit the following url:


It will show product list like the picture below:

Please click one of the delete buttons on the action column to delete the record.

That's it.

5. Update data to database (Update).

You already know how to display data (READ) from database to view, Insert data to

database (CREATE), and delete data to database (DELETE).

Now its time to know how to change data to database (UPDATE).

Let’s begin.

#1. Open the view file "product_view.php". And then edit to the following:

<!DOCTYPE html>

<html lang="en">

<head>





</head>

<body>




<thead>

<tr>




<th width="200">Action</th>

</tr>

</thead>

<?php

$count = 0;


$count++;

?>

<tr>




<td>

<a href="<?php echo site_url('product/get_edit/'.$row->product_id);?>" class="btn btn-sm btn-info">Update</a>

<a href="<?php echo site_url('product/delete/'.$row->product_id);?>" class="btn btn-sm btn-danger">Delete</a>

<td>

</tr>

<?php endforeach;?>

</tbody>

</table>

</div>





</body>

</html>

In the "product_view.php" file above we add one more button to the action column.

That is the edit button.

So if you run Controller product, by visiting the following url:

http://localhost/myproject/product/


#2. Add a function function get_edit on Product.php controller.


function get_edit(){


$result = $this->product_model->get_product_id($product_id);

if($result->num_rows() > 0){

$i = $result->row_array();

$data = array(

'product_id' => $i['product_id'],

'product_name' => $i['product_name'],

'product_price' => $i['product_price']

);

$this->load->view('edit_product_view',$data);

}else{

echo "Data Was Not Found";

}

}

#3. Add a function “function get_product_id” on Product_model.php controller.


function get_product_id($product_id){

$query = $this->db->get_where('product', array('product_id' => $product_id));

return $query;

}

#4. Create one more view named "edit_product_view.php". Then type the following

code:

<!DOCTYPE html>

<html lang="en">

<head>


<title>Edit Product</title>



</head>

<body>


<h1><center>Edit Product</center></h1>

<div class="col-md-6 offset-md-3">

<form action="<?php echo site_url('product/update');?>" method="post">


<label>Product Name</label>

<input type="text" class="form-control" name="product_name" value="<?php echo $product_name;?>" placeholder="Product Name">

</div>


<label>Price</label>

<input type="text" class="form-control" name="product_price" value="<?php echo $product_price;?>" placeholder="Price">

</div>

<input type="hidden" name="product_id" value="<?php echo $product_id?>">

<button type="submit" class="btn btn-primary">Update</button>

</form>

</div>

</div>





</body>

</html>

#5. Add a more function named “function update” on Product.php controller.

And then type the following code:

function update(){

$product_id = $this->input->post('product_id');



$this->product_model->update($product_id,$product_name,$product_price);


}

So look full code from the controller Product.php below:

<?php





}

function index(){



}

function add_new(){


}

function save(){





}

function delete(){




}

function get_edit(){


$result = $this->product_model->get_product_id($product_id);

if($result->num_rows() > 0){

$i = $result->row_array();

$data = array(

'product_id' => $i['product_id'],

'product_name' => $i['product_name'],

'product_price' => $i['product_price']

);

$this->load->view('edit_product_view',$data);

}else{

echo "Data Was Not Found";

}

}
