Codeigniter--Cross-site Scripting

After Image-uploading, We will be learning about Cross-site Scripting.

1. Rename your Codeigniter folder as "ScriptIgniter".

2. Now configure your files.Go to C:\xampp\htdocs\ScriptIgniter\application\config.
Now select autoload.php and make changes as follows.

$autoload['libraries'] = array('security', 'xmlrpc');

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

3. Select config.php and make the changes as follows.

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

4. Select routes.php and make the changes as follows.

$route['default_controller'] = "form_controller";

$route['404_override'] = '';

5. Create a new folder named "css" in C:\xampp\htdocs\ScriptIgniter.

6. Now create a new file form_controller.php in C:\xampp\htdocs\ScriptIgniter\application\controllers

and copy and paste the code given below.

form_controller

7. Now create a new file form_view.php in C:\xampp\htdocs\ScriptIgniter\application\views and copy and paste the code given below.

7. Create a new file model.php in C:\xampp\htdocs\insertigniter\application\models.Here is the code. Just copy and paste it.

model.php

8.Create a css folder in C:\xampp\htdocs\insertigniter and create a file named styles.css. Just copy and paste the following code.

styles.css

9. For the database part, just copy and paste in your database.

10. Now redirect to http://localhost/insertigniter/index.php/vcontroller.
11. You should get the following screen.

That's it!,In the next tutorial,we will be learning about Captcha-generated Form.

Codeigniter-Simple Application

After Configuring the files, We are all set to develop a simple application.

The simple application is displaying "Hello World!!".It sounds funny, but to display these two words in Codeigniter we are going to use View and Controller.So lets proceed with the tutorial.

1. Now go to your Codeigniter application folder and change the name of the folder as projectigniter and go to C:\xampp\htdocs\projectigniter\application\config and click on routes.php and make the following changes.

$route['default_controller'] = "";
as
$route['default_controller'] = "hello_controller";

2. Include "url" in autoload.php in the helper.

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

3. Now create a page hello_contoller.php within \xampp\htdocs\projectigniter\application\controllers.
4. Just copy and paste the code given bellow.

   hello_controller.php

5. Next create a page words_view.php within \xampp\htdocs\projectigniter\application\controllers.
6. Copy and paste the words given bellow.

words_view.php

7. Now the application in your browser as http://localhost/projectigniter/.
8. You should get the screen as below.

That's all!!, We have successfully developed our first and simple application.In our next tutorial we will be learning about google Recaptcha-login form.

Codeigniter--Configuring Files

After Installation Concept, We will be learning about how to Configure Codeigniter files.

The Codeigniter Framework can't be used as it. Because the files in the Codeigniter folder must be configured and its a mandatory. So in this tutorial, we are going to learn about configuring the files.

1. Go to C:\xampp\htdocs\yourCIfolder\application\config and select autoload.php. In this file, you will find $autoload['libraries'] = array();. libraries like xmlrpc, database, and session are to be loaded in it.

autoload.php

2. In the same autoload.php file, you will find $autoload['helper'] = array();. Helpers like url, file, and form should be included.

autoload.php

3. Again in autoload.php, you will find $autoload['model'] = array();. Files with models(eg. file_model.php) will be included in it.

autoload.php

4. In the same config folder, you will find another file named config.php. When you scroll down, you will find $config['encryption_key'] = '';. When you are using the session and Encryption in your autoload.php, you should also use encryption_key for it.You can give either alphabets or numbers even special characters as keys.

config.php

5. These are the basic libraries and helpers that are to be used before working in Codeigniter. Apart from these two files, there are database.php and routes.php which we will learn in the following tutorials.

In the next tutorial, we will be developing a simple application.

Codeigniter--Installation

After MVC Concept, We will be learning about how to install Codeigniter.

1. Download the Codeigniter Framework any version after Using the stable version 2.2 will be well and good.

2. After downloading the file, unzip it and store in local Disk(C:) or in another disk.

3. Save the Codeigniter folder in C:\xampp\htdocs\YourCIfolder.(I prefer using XAMPP if you use WAMP, unzip the file in C:\wamp\www.)

4. Rename the Codeigniter folder as you wish for your project. (eg.Projectigniter)

5. Now go to YourCIfolder\application\config and open config.php.

6. In config.php file, you can see $config['base_url'] = '';. Inside the single-quotes write like this. $config['base_url'] = 'http://localhost/YourCIfolder/';.

7. Double-click on the link(http://localhost/projectigniter/) and you will find the screen.

8. That's it! you successfully installed the Codeigniter in your Computer.

In the next tutorial, we will be learning about configuring the Codeigniter files.
