In my previous article, I have explained about how to install and configure the Codeigniter on your localhost. In this article, I'm going to describe How to create a Ajax pagination in Codeigniter. Codeigniter has many buil-in classes and plugins. Codeigniter pagination is easy to use.

Step 1: 

Download the Pagination classes from the Codeigniter site.

Click Here to download the Codeigniter Ajax pagination library files.

Step 2: 

Put the Ajax pagination library files to the "system/libraries" folder.

Step 3: 

Also download the prototype.js file and place anywhere on your root.

Step 4: 

Create a database table to store and retrieve the records to apply the pagination.

CREATE TABLE `my_best_friends` (
  `f_id` int(11) NOT NULL auto_increment,
  `f_name` varchar(100) NOT NULL,
  `f_phone` int(11) NOT NULL,
  `f_email` int(11) NOT NULL,
  `f_address` int(11) NOT NULL,
  PRIMARY KEY  (`f_id`)
)

Step 5:

Add the below code in your "Controller" file

class Paging extends Controller {
  function Paging(){
  parent::Controller();
$this->load->helper(array('form','url'));
$this->load->helper('text');
$this->load->library('Ajax_pagination');
}
  function index()
{
redirect ('paging/my_friends');
}
  function my_friends()
{
$pdata['TotalRec'] = $this->FriendsModel->TotalRec();
$pdata['perPage'] = $this->perPage();
$pdata['ajax_function'] = 'get_friends_ajax';
  $subdata['paging'] = $this->parser->parse('paging', $pdata, 
TRUE);
$subdata['all_friends'] = $this->FriendsModel->my_friends
($this->perPage());
  $data['body_content'] = $this->parser->parse('friend_list', 
$subdata, TRUE);
  $this->load->view('main',$data);
}
  function get_friends_ajax()
{
             $pdata['TotalRec'] = $this->FriendsModel->TotalRec();
             $pdata['perPage']  = $this->perPage();
      $pdata['ajax_function'] =  'get_friends_ajax';
      $data['paging'] =  $this->parser->parse('paging', $pdata, TRUE);
    $data['all_friends'] = $this->FriendsModel->my_friends($this->perPage());
      $this->load->view('friend_list',$data);
}
  function PerPage()
{
return 5;
}
 }

Step 6:

Add the below code in your "Model" file

class FriendsModel extends Model
{
    function FriendsModel()
    {
parent::Model();
}
  function TotalRec()
{
 $sql = "SELECT * FROM my_friends";
          $q = $this->db->query($sql);
          return $q->num_rows();
       }
  function my_friends($perPage)
{
$offset = $this->getOffset()
$query ="SELECT * FROM  my_friends Order By f_id Desc LIMIT ".$offset.", ".$perPage;
$q = $this->db->query($query);
return $q->result();
}
  function getOffset()
{
        $page = $this->input->post('page');
        if(!$page):
        $offset = 0;
        else:
        $offset = $page;
        endif;
        return $offset;
    }
}

Step 7:

Add the below code in your "paging.php" file in "application/views/" folder.

$config['first_link'] = 'First';
$config['div'] = 'container'; //Div tag id
$config['base_url'] = base_url().'paging/'.$ajax_function;
$config['total_rows'] = $TotalRec;
$config['per_page'] = $PerPage;
$config['postVar'] = 'page';

$this->ajax_pagination->initialize($config);
echo $this->ajax_pagination->create_links();

Step 8:

Add the below code in your "friend_list.php" file in "application/views/" folder.

<table border="1" width="200">
<tbody>
<tr>
<td>Friend Name</td>
<td>Friend Phone</td>
<td>Friend Address</td>
</tr>
foreach($all_friends as $row)
 {
<tr>
<td>echo $row->f_name</td>
<td>echo $row->f_phone</td>
<td>echo $row->f_address</td>
</tr>
}</tbody>
</table>

Step 9:

In main home page.,

Add the below code to your "main.php" file in "application/views/" folder. This file

contains your html code and all css and js files.

<div id="container">
     echo @$body_content;
</div>

Click Here to learn more about How to Install and configure codeigniter on your localhost.

In this tutorial, we are going to discuss about how to install and configure the Codeigniter (CI) PHP framework on your localhost. Configuring codeigniter to our localhost is so simple and easy. In this article I will explain the step bt step procedure to install and configure Codeigniter framework on your localhost.


1, Download Codeigniter system folder from codeigniter.com

2, Now unzip it and paste it

3, After unzipping folder copy this folder to your localhost server and change its name to some thing like “mywork”.

4, Update system/application/config/config.php  file. Change base url to your localhost path.

5, Give DB name to system/application/config/database.php which you create on localhost.

Now its ready to use just go to your browser and access your first testing codeigniter configured site on localhost.

In this article we are going to discuss about how to reading and writing the session data using the Zend Session Namespace in Zend Framework. Also discuss about some useful techniques of Zend Framework session and Session Namespace.

In Zend framework, you can use both Zend_Session and Zend_Session_Namespace which extends abstract class Zend_Session_Abstract. So these two inherited methods are available in Zend_Session_Abstract automatically. In Zend/Session/Abstract.php file, you can find all functions related to session handling.

$mysession = new Zend_Session_Namespace(’Namespace’);

The argument for namespace is optional, but it’s better to pass it. if you don’t pass it, Zend Session Namespace will assign its name a string “default”. To store values in session variable, you will need to do the following.

$mysession->fruits = ‘Apple’;

Below is the example code to retrieve values from session.

$yoursession = new Zend_Session_Namespace(’Namespace’);
$fruits = $yoursession->fruits;

If you want to go deep, you can get many useful functions in Zend_Session_Abstract.php, Zend_Session_Nampspace.php, and Zend_Session.php.

WordPress provides easy way to create and manage your blog. you can easily modify, customize and enhance functionality of your WordPress blog. You don’t need to change the core functionality of your WordPress blog. it provides easy way to add functionality with WordPress plugins. A WordPress plugin is a progam or can say a set of one or more functions which is written in the PHP scripting language which adds a specific set of features to your WordPress blog.

In my previous post, I have explained about how to create our own Front End Component in Joomla. In this post I will explain about How to create a Back End Component in Joomla and how to activate and execute the Back End Component in Joomla. Back End means, only an administrator can access this page. So we are going to work under the "Administrator" folder. Joomla separates the folder between front end and back end.

Here are the steps:

Step 1:

Create a folder for your component in Joomla administrator components directory.

Ex: root folder/administrator/components/com_mycomponent

Here "com_mycomponent" is our new component name.


Step 2:

Create a file "admin.mycomponent.php" inside the "com_mycomponent" folder.

Codeigniter provides many built in helpers and libraries which help us to perform lot of functionality for developing projects. Here a simple email library make us able to send email using our Gmail account living in CI environment.


<?
class Send_Email extends Controller
{
function Send_Email()

{
parent::Controller();
}
function index()
{
  $config = Array(
  'protocol' => 'smtp',
  'smtp_host' => 'ssl://smtp.googlemail.com',
  'smtp_port' => 465,
  'smtp_user' => 'email_address@gmail.com', // change it to yours
  'smtp_pass' => 'your_password', // change it to yours
  'mailtype' => 'html',
  'charset' => 'iso-8859-1',
  'wordwrap' => TRUE
);

  $this->load->library('email', $config);
  $this->email->set_newline("\r\n");
  $this->email->from('your_email@domain.com'); // change it to yours
  $this->email->to('your_email@domain.com'); // change it to yours
  $this->email->subject('Email using Gmail.');
  $this->email->message('Working fine ! !');

  if($this->email->send())
 {
  echo 'Email sent.';
 }
 else
{
 show_error($this->email->print_debugger());
}
}
}
?>

Authorize.Net is a favorite payment mode used in web development. It is simple, easy and secure payment connection. I use authorize.Net in my codeigniter based projects and here is the code.

This is helper for payment.

function do_payment ($post_values)
{
        $post_url = "https://test.authorize.net/gateway/transact.dll";  
        // This section takes the input fields and converts them to the proper format
$post_string = "";
foreach( $post_values as $key => $value )
{ $post_string .= "$key=" . urlencode( $value ) . "&"; }
  $post_string = rtrim( $post_string, "& " );

// This sample code uses the CURL library for php to establish a connection,
// submit the post, and record the response.
// If you receive an error, you may want to ensure that you have the curl
// library enabled in your php configuration

$request = curl_init($post_url); // initiate curl object

curl_setopt($request, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response

curl_setopt($request, CURLOPT_RETURNTRANSFER, 1); // Returns response data instead of TRUE(1)
curl_setopt($request, CURLOPT_POSTFIELDS, $post_string); // use HTTP POST to send form data
curl_setopt($request, CURLOPT_SSL_VERIFYPEER, FALSE); // uncomment this line if you get no gateway response.
$post_response = curl_exec($request); // execute curl post and store results in $post_response

// additional options may be required depending upon your server configuration
// you can find documentation on curl options at http://www.php.net/curl_setopt
curl_close ($request); // close curl object

// This line takes the response and breaks it into an array using the specified delimiting character
$response_array = explode($post_values["x_delim_char"],$post_response);

// The results are output to the screen in the form of an html numbered list.
if($response_array)
{
return $response_array;
}
 else { return ''; }
}

And here is your controller function:


function do_user_payment()
{
     $this->load->library('auth_payment');
     $card_expiration = $_POST['crMonth'].$_POST['crYear'];

     $x_login   = "login_key";
     $x_tran_key  = "trans_key";
     $card_number = $_POST['ccn']; 

     $invoice_num = '';

     $x_card_code = $_POST['CSV'];

     $post_values['x_invoice_num'] = $invoice_num;
     $post_values['x_login'] = $x_login;
     $post_values['x_tran_key'] = $x_tran_key;

     $post_values['x_card_code'] = $x_card_code;

      $post_values['x_version'] = "3.1";
      $post_values['x_delim_data'] = "TRUE";
      $post_values['x_delim_char'] = "|";
      $post_values['x_relay_response'] = "FALSE";

      $post_values['x_type'] = "AUTH_CAPTURE"; //Optional
      $post_values['x_method'] = "CC";
      $post_values['x_card_num'] = $card_number;
      $post_values['x_exp_date'] = $card_expiration;
      $post_values['x_amount']   =  'Your Charges';

      $post_values['x_first_name'] = $user_first_name; //Optional (From Client)
      $post_values['x_last_name'] = $user_last_name; //Optional (From Client)
      $post_values['x_address'] = $user_address1; //Optional (From Client)
      $post_values['x_state'] = $user_state; //Optional (From Client)
      $post_values['x_zip'] = $user_zip; //Optional (From Client)

      //Calling Payment function

     $paymentResponse = $this->auth_payment->do_payment($post_values);

     if($paymentResponse[0]==1 && $paymentResponse[1]==1 && $paymentResponse[2]==1)
     {
          // payment is successful. Do your action here
     }
    else
     {
          // payment failed.
          return $paymentResponse[3]; // return error
     }
}
