I had a problem with Norwegian characters today. I found that my editor’s encoding was set to iso-8859-1, so I needed to change it to UTF-8. I kept the following in config.php in CodeIgniter.

$config['charset'] = "UTF-8";

Then I needed to retype all the Norwegian characters in the editor.

I set all database charset to UTF-8 as well.

DEFAULT CHARSET=utf8

This is a quick tip to change your document root in Ubuntu. If you are using github, it is a bit troublesome to work in /var/www directory. You need to type ‘sudo’ each time or change to super user. But if you change your localhost document root to your home directory, you don’t need to do it.

From terminal.

Change the following line.

to the following.

Don’t forget to change ‘yourdirectory’.

Then from terminal.

Then transfer all your directory from /var/www to /home/yourname/www.

If you are using Ubuntu and having a problem or setting up sending email from localhost, you can use Msmtp. In this article I go through how to install msmtp and create some hml and php files to test it. Furthermore I will explain how to set up email config for BackendPro which is a control panel for CodeIgniter.
You will see how easy to set it up.

Credit goes to this and this article.

Install msmtp and ca-certificates for use with SSL:

sudo apt-get install msmtp ca-certificates

Open msmtprc to edit.
If you don’t know where msmtprc, then use ‘which msmtprc’ in terminal

sudo gedit /etc/msmtprc

Add the followings to this file.

defaults
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt

account default
host smtp.gmail.com
port 587
auth on
user username(at)gmail.com
password mypass
from username(at)gmail.com
logfile /var/log/msmtp.log

Change username(at) with your username and mypass with your password for gmail.

Change file permission.

sudo chmod 0644 /etc/msmtprc

Open php.ini to edit

sudo gedit /etc/php5/apache2/php.ini

Uncomment ‘sendmail_path’ and add this.

sendmail_path = '/usr/bin/msmtp -t'

Restart apache

sudo /etc/init.d/apache2 restart

Testing

Then test with the following code.

Method 1
Create /var/www/mail.htm

<form method="post" action="sendmail.php">
Email: <input name="email" type="text" /><br />
Message:<br />
<textarea name="message" rows="15" cols="40">
</textarea><br />
<input type="submit" />
</form>

And /var/www/sendmail.php

<?php
$email = $_REQUEST['email'] ;
$message = $_REQUEST['message'] ;

mail( "youremail(at)gmail.com", "Feedback Form Results",
$message, "From: $email" );
header( "SUBJECTHERE" );
?>

Change youremail(at)gmail.com to whatever you like. Then go to http://localhost/mail.htm to fill up the form.

Method 2

Create /var/www/mail1.php and add this.

<?php
if ( mail ( 'youremail(at)gmail.com', 'Test mail from localhost', 'Working Fine.' ) ){
echo 'Mail sent';
}
else{
echo 'Error. Please check error log.';
}
?>

Change youremail(at)gmail.com to your email for receiving this email. And visit http://localhost/mail1.php to send email.

BackendPr0

If you are using any BackendPro applications then login to the backend and go to System>Settings>Email configuration. Change ‘Sendmail path’ feild to /usr/bin/msmtp -t and ‘Email’ to Sendmail from a dropdown.

3. Windows in VM Virtualbox on Ubuntu, localhost and base url of CodeIgniter

Following up from the previous Aha moment post, this is Aha moment 2 and I am accessing localhost on Ubuntu from Windows 7 in VM Virtualbox. I have VM Virtualbox on Ubuntu 10.10 and I installed Windows 7 in this virtualbox. If I tried to access localhost on Ubuntu from a browser in Windows 7, I get an error. So this is how to access it.

The first thing to check is Ubuntu side. Open if you have nothing in /etc/apache2/httpd.conf. If you have any virtual host you need to delete them and restart the apache. If it is clear, then on terminal type ifconfig to check your inet addr.

Mine is following.

eth0  ...
	...
	...

lo	...
	...
	...
wlan0		...
		inet addr:192.168.1.2 Bcast ....

Find inet addr. Mine is 192.168.1.2.

Start your VM Virtualbox and Windows 7. Open your browser and type http://192.168.1.2/mysite/.

If your web app is on CodeIgniter, then open system>application>config>config.php and change the following.

$config['base_url']	= "http://192.168.1.2/mysite/";

And it should show your website from localhost on Ubuntu.

Well I had a aha moment today, so I thought I should share this. I know that the title is a bit confusing.

There are times still I have to use Windows. And there are times when you have to develop for IE7. My set up for this is using IE 7 on Windows XP which is installed in VMware running on Windows 7. Well I could do it on Ubuntu as well. And I use XAMPP on Windows 7 for development.

Use IPv4 Address value

I had a hard time to display localhost on IE 7. When I use http://localhost/mywebsite, it works fine in my browsers on Windows 7, but it did not display in browsers in Windows XP. In a short answer, use http://192.168.1.2/. If this does not work for you, read on.

On Windows 7, go to Control panes > Network and Internet > Networking and Sharing center, then click your wireless connection or if you are using cable, then cable connection. Please note that it is not a VMware Adapters. When you open the Wireless Network Connection status, click Details. Find the vaule for IPv4 Address. For me it is 192.168.1.2. Use this in a browser in VMware to display a localhost from Windows 7.

Using CodeIgniter?

If you are using CodeIgniter, then you need to do one more step. Open your system>application>config>config.php and add the following to your base_url.

$config['base_url']	= "http://192.168.1.2/mywebsite/";

Without this line, all the internal links, images, CSS and scripts are broken. Adding this will fix the problems.

This post is about how to use Zend Framework on Codeigniter to show Youtube videos.

Download

Note:

The download file is set up for Windows. If you are not using Windows, then open application/helpers/zend_framework_helper.php and comment out Windows part and uncomment the other part.

<?php
// For Windows
ini_set("include_path", ini_get("include_path").PATH_SEPARATOR.str_replace("/", "\\", BASEPATH)."contrib\\");
require_once ('Zend/Loader.php');

// For Non-Windows
/*
ini_set("include_path", ini_get("include_path").PATH_SEPARATOR.BASEPATH."/contrib/");
require_once 'Zend/Loader.php';
*/

?>

Implement Zend Framework in Codeigniter

First you have to implement Zend Framework in Codeigniter. Please read this post.

Controller/youtube2.php

Create a file and add the following code.

<?php
class Youtube2 extends Controller{
    protected $_youTube;

function __construct() {
    parent::Controller();
    Zend_Loader::loadClass('Zend_Gdata_YouTube');
    $this->_youTube = new Zend_Gdata_YouTube;
    }

function index(){
      // Gets playlists
    $data['playlistfeed']= $this->_youTube->getPlaylistListFeed('NationalGeographic');
    $this->load->view ('youtube_view2',$data);
    }

public function listAction(){
    // Gets playlist videos
    $playlistId = $this->uri->segment(4);
    $query = $this->_youTube->newVideoQuery(
    'http://gdata.youtube.com/feeds/playlists/' . $playlistId);
    $data['videoFeed']= $this->_youTube->getVideoFeed($query);
    $this->load->view('listaction_view', $data);
    }

public function viewAction(){
    // Gets video
    $videoId = $this->uri->segment(4);
    $data['videoId'] = $this->uri->segment(4);
    $data['videoEntry'] = $this->_youTube->getVideoEntry($videoId);
    $this->load->view('youtube_video_view', $data);
    }
}

Firstly I am adding a protected variable $_youTube.
In the constructor, I load the class Zend_Gdata_Youtube, and create a new object.

In the function index, I add a variable playlistfeed and send it to a view called youtube_view2 which I am going to create it shortly.

I am going to collect National geographic videos in this case. You can change it as you wish.

views/youtube_view2.php

Create a file and add the following code.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <title>Video lists</title>

</head>
<body>
<h1>National Geographic Videos on Youtube</h1>
<dl>
<?php foreach ($playlistfeed as $playlistEntry): >
<?php $id = substr(strrchr(
$playlistEntry->getPlaylistVideoFeedUrl(), '/'
), 1); >
<dt>
<a href="youtube2/listAction/id/<?php echo $id; >/">
<?php echo $playlistEntry->title->text; >
</a>
</dt>
<dd><?php echo $playlistEntry->description->text; ></dd>
<?php endforeach; >
</dl>

</body>
</html>

This will output the following html.

...
<h1>National Geographic Videos on Youtube</h1>
<dl>
<dt>
<a href="youtube2/listAction/id/746AD498C993B957/">
Oceans</a>

</dt>
<dd>Explore the beauty of the world's oceans.</dd>
<dt>
<a href="youtube2/listAction/id/355D512277EFFA06/">
Animal Attack!</a>
</dt>
...
...

When you click a link, it will take you listAction() function in youtube2 class and the fourth segment will be used as id in that class.

views/listaction_view.php

Create a file and add the following code.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <title>Youtube Video Details</title>

</head>
<body>

<h1>National Geographic Videos on Youtube. Videos about <?php echo $videoFeed->title->text; ></h1>
<dl>
<?php foreach ($videoFeed as $videoEntry): >
<?php $id = substr(strrchr($videoEntry->getFlashPlayerUrl(), '/'),
1); >

<dt>
    <h2>
        <?php echo "Video Title: ". $videoEntry->mediaGroup->title->text; >

</h2>
   <h3> <?php echo anchor("youtube2/viewAction/id/$id/","Watch Video");>
</h3>

</dt>
<dd><?php echo $videoEntry->mediaGroup->description->text. "<br /><br />"; >
<b><?php echo "Video id: ". $id; >
</b>
</dd>
<?php endforeach; >
</dl>

</body>
</html>

This listAction() function outputs the following html.

...
<h1>National Geographic Videos on Youtube. Videos about Oceans</h1>
<dl>

<dt>
    <h2>
        Video Title: Feeding Frenzy: Manta Rays in the Maldives
</h2>
   <h3> <a href="http://127.0.0.1/ci_zend/index.php/youtube2/viewAction/id/yihoIvUBDM4?f=playlists&amp;amp;app=youtube_gdata">Watch Video</a></h3>

</dt>
<dd>When tide and current turn a tiny bay into a bowl of plankton, manta rays in the Maldives gather for a roiling, whirling feast.<br /><br /><b>Video id: yihoIvUBDM4?f=playlists&amp;amp;app=youtube_gdata</b>
</dd>

<dt>
    <h2>
        Video Title: Penguins vs. Pelicans
</h2>
   <h3> <a href="http://127.0.0.1/ci_zend/index.php/youtube2/viewAction/id/Fhmm-A8wBzk?f=playlists&amp;amp;app=youtube_gdata">Watch Video</a></h3>

</dt>
...
...

The links will take you to youtube2 viewAction () function with Youtube video identifier.
The viewAction() function will take the forth segment and show a video in the next step.

views/youtube_video_view.php

Create a file and add the following code.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
  <title>Watch: Youtube Videos</title>

</head>
<body>

<h1><?php echo $videoEntry->mediaGroup->title->text; ></h1>
<object width="425" height="355">
<param name="movie"
value="http://www.youtube.com/v/<?php echo $videoId; >&amp;amp;rel=0">

type="application/x-shockwave-flash"
wmode="transparent" width="425" height="355">

</object>

</body>
</html>

This view outputs the following html.

...

There are quite few posts how to use Zend framework in Codeigniter.

1. Beyond Coding
2. Freakauth
3. Phil’s post

However none of them worked on my XAMPP. I thought there might be some who are struggling to use Zend frame work on Windows. Here is how I did.

Here you can read why they don’t work with Windows.

Adding Zend Framework

Here you can read how to add Zend Framework. And I use this structure for this post.

You need to create a folder ../system/contrib/ and add Zend folders in this folder.

../system/
         contrib/
               Zend/
                     Acl/
                     Acl.php
                     Amf/
                     Amf.php ...

Create a file system/application/helpers/zend_framework_helper.php and add the following.

<?php
ini_set("include_path", ini_get("include_path").PATH_SEPARATOR.str_replace("/", "\\", BASEPATH)."contrib\\");
require_once ('Zend/Loader.php');
?>

If you are not using Windows, then add the following instead.

ini_set("include_path", ini_get("include_path").PATH_SEPARATOR.BASEPATH."/contrib/");
require_once 'Zend/Loader.php';

Adding it in autoload.php

Open config/autoload.php and add the following.

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

Using Zend in Codeigniter

Now you can load any Zend class by adding Zend_Loader::loadClass(‘ZEND-CLASS-HERE’);.
You can see all the Zend classes here. http://framework.zend.com/manual/en/

Here are three examples.

Zend_Service_Flickr

Create a file controllers/flickr.php and add the following.

<?php
class Flickr extends Controller
{
function __construct()
{
parent::Controller();

}

function index()
{

Zend_Loader::loadClass('Zend_Service_Flickr');

$flickr = new Zend_Service_Flickr('ADD-YOUR-KEY-HERE');
try
{

$results = $flickr->tagSearch("cat");
if ($results->totalResults() > 0)
{

foreach ($results as $result)
{
echo '<img src="'.$result->Square->uri.'" />';
}

}
else
{
echo '<p style="color: orange; font-weight: bold">No Results Found.</p>';
}
}
catch (Zend_Service_Exception $e)
{
echo '<p style="color: red; font-weight: bold">An error occured, please try again later. (' .$e->getMessage(). ')</p>';
}

}
}

?>

Don’t forget to change ADD-YOUR-KEY-HERE to your Flickr key.
If you don’t have one, get it from here.
Then visit your controller, http://127.0.0.1/codeigniter/index.php/flickr to see the result.

Using Zend_Gdata_YouTube

Create another file controllers/youtube.php and add the following.

<?php
class Youtube extends Controller
{
function __construct()
{
parent::Controller();

}

function index()
{

    Zend_Loader::loadClass('Zend_Gdata_YouTube');
    $youtube = new Zend_Gdata_YouTube();
    $query = $youtube->newVideoQuery();
    $query->videoQuery = 'cat';
    $query->startIndex = 10;
    $query->maxResults = 20;
    $query->orderBy = 'viewCount';

    $data['queryurl'] =  $query->queryUrl;
    $data['videofeed'] =  $youtube->getVideoFeed($query);
    $this->load->view('youtube_view', $data);
  }
}

?>

views/youtube_view.php

Create this file and add the following.

<?php

foreach ($videofeed as $videoEntry) {
    echo "---------VIDEO----------<br />";
    echo "Title: " . $videoEntry->getVideoTitle() . "<br />";
    echo "\nDescription:<br />";
    echo $videoEntry->getVideoDescription();
    echo "<br /><br />";
}
?>

Then visit a new page http://127.0.0.1/codeigniter/index.php/youtube to the result.

Using Google calendar

Create controller/googlecalendar.php and add the following. Use your google email and password.

<?php
class Googlecalendar extends Controller
{
function __construct()
{
parent::Controller();

}

function index()
{
    Zend_Loader::loadClass('Zend_Gdata_Calendar');
     Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
    // Parameters for ClientAuth authentication

$user = "YOUR gmail HERE";
$pass = "YOUR PASS";

$service = Zend_Gdata_Calendar::AUTH_SERVICE_NAME;
$client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service);
$service = new Zend_Gdata_Calendar($client);

try {
    $listFeed= $service->getCalendarListFeed();
} catch (Zend_Gdata_App_Exception $e) {
    echo "Error: " . $e->getMessage();
}
echo "<h1>Calendar List Feed</h1>";
echo "<ul>";
foreach ($listFeed as $calendar) {
    echo "<li>" . $calendar->title .
         " (Event Feed: " . $calendar->id . ")</li>";
}
echo "</ul>";
}
}
?>

Then again visit http://127.0.0.1/codeigniter/googlecalendar.

I posted how to implement Zend Framework here. However I had a problem with Window’s path when I was trying it.

I have found a couple of things about paths in Windows when I am using Codeigniter.
As all know that Windows uses \ for the path. For example, C:\xampp\htdocs\codeigniter\system\contrib. Linux uses / for the path. For example, /home/1/o/mywebsite/www/codeigniter/system/.

If you are using XAMPP or WAMP for your web development, you might have a problem with this difference.

BASEPATH in Codeigniter

Enter the following to view/welcome_message.php in your freshly installed Codeigniter.

echo 'Basepath: ' . BASEPATH . '<br />';

And visit http://127.0.0.7/codeigniter/index.php/welcome.
You will see the following.

1. Basepath: C:\xampp\htdocs\codeigniter/system/

Did you notice \codeigniter/?

In practical situation, you would add the following for your live server(Linux).

ini_set("include_path", ini_get("include_path").
PATH_SEPARATOR.BASEPATH."/contrib/");

However this will not work on your Windows.
You need to use the following instead.

ini_set("include_path", ini_get("include_path").
PATH_SEPARATOR.str_replace("/", "\\", BASEPATH)."contrib\\");

str_replace() function will replace / in BASEPATH with \.

If you want to see some of your paths in Codeigniter, add the following in your view/welcome_message.php and see the results.

<html>
<head>
<title>Welcome to CodeIgniter</title>

Background and Credits

I learnt Codeigniter from a book “Professional Codeigniter” by Mr. Thomas Myer.

I started learning PHP six months ago and read a couple of good books about PHP and I had basic knowledge but not practical experience of PHP.

Professional Codeigniter was delightful to read. I have learnt a lot from the book. I highly recommend the book if you are a beginner like me and want to learn CI in practical ways.

Especially I enjoyed it in three ways.
1. There are some bugs which could not make it for the final edition. But I am glad that it did not make it. Because fixing these taught me more than I expected. I used the book forum, CI forum and Stackoverflow to solve the problems.

2. Reading a book which teachs you how to create one applicatoin, in this case is shopping cart, is the best way for me to learn PHP and CI.

3. While I was reading the book, I wanted to change the application in my way. And this was again good learning for me.

I recommend the book and read through it to understand fully.

I obtained a permission from the author and I’d like to add my version of updated code here.

Updates

Fixed ALL the bugs in front-end and back-end. (hopefully)

As I stated it before the author’s final code did not make the printed edition. So there are some mistakes and typos. So I corrected as much as possible. I don’t say that it is complete, but nearly.

Added captcha to newsletter subscribe.

I wrote a small post here about it.

Added a contact page with captcha.

Updated to CI 1.7.2

It seems the original code was developed with 1.6 or so. I updated to 1.7.2.

Changed to jQuery

Original code had Prototype for javascript. I migraged to jQuery.

Added a nudge menu to the front-end

Once I added jQuery, there are many menus I could add. However I just chose David Walsh’s nudge menu for the front sub-menu.

Random feature products images have a link to product page

There are random feature products on the right column. I added links to individual product pages.

Changed admin/products to show more details including categor names

Products page shows more details

Search function does not pick up inactive products

Added table-sort function (jQuery) to all the backend pages

This enables to sort in both ways, including show rows (10, 20, 30, etc) as well.
I used jQuery Data tables plugin for this.

Scroll to top

Here is how.

And more

I changed other small items which I don’t remember.

DOWN LOAD
In the previous post I wrote a basic method how to use captcha plug-in with Codeigniter.
Today I am going to write a simple but practical newsletter subsciption page using captcha.
We will use CI’s form_validation class.

ci_captcha

Please read the previous post to customize it.
You need to create a folder called captcha as the same level as system.

Database

We need two tables, captcha and subscribers.

CREATE TABLE IF NOT EXISTS `captcha` (
  `captcha_id` bigint(13) unsigned NOT NULL AUTO_INCREMENT,
  `captcha_time` int(10) unsigned NOT NULL,
  `ip_address` varchar(16) NOT NULL DEFAULT '0',
  `word` varchar(20) NOT NULL,
  PRIMARY KEY (`captcha_id`),
  KEY `word` (`word`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=20 ;

CREATE TABLE IF NOT EXISTS `subscribers` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=30 ;

Config

config/autoload.php

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

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

You can autoload library(form_validation) here as well.

Model

The code is from a Codeigniter book Professional CodeIgniter by Thomas Myer.

models/msubscribers.php

<?php

class MSubscribers extends Model{

	function MSubscribers(){
		parent::Model();
	}

function getSubscriber($id){
    $this->db->where('id',$id);
    $this->db->limit(1);
    $Q = $this->db->getwhere('subscribers');
    if ($Q->num_rows() > 0){
      $data = $Q->row_array();
    }

    $Q->free_result();
    return $data;
 }

 function getAllSubscribers(){
     $data = array();
     $Q = $this->db->get('subscribers');
     if ($Q->num_rows() > 0){
       foreach ($Q->result_array() as $row){
         $data[] = $row;
       }
    }
    $Q->free_result();
    return $data;
 }

 function createSubscriber(){
	$this->db->where('email', $_POST['email']);
	$this->db->from('subscribers');
	$ct = $this->db->count_all_results();

	if ($ct == 0){
		$data = array(
			'name' => $_POST['name'],
			'email' => $_POST['email']
		);

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

 function updateSubscriber(){
	$data = array(
		'name' => $_POST['name'],
		'email' => $_POST['email']

	);

 	$this->db->where('id', $_POST['id']);
	$this->db->update('subscribers', $data);	

 }

 function removeSubscriber($id){
 	$this->db->where('id', $id);
	$this->db->delete('subscribers');

 } 

}//end class
?>

Controller

controllers/welcome.php

<?php
class Welcome extends Controller {
  function  __construct(){
    parent::Controller();
    $this->load->model('MSubscribers');
    $this->load->helper(array('form', 'url'));
    $this->load->library('form_validation');
    session_start();
    $this->output->enable_profiler(FALSE);
  }

    	$captcha_result = '';
	$data['cap_img'] = $this -> _make_captcha();
	$this->load->view('subscribe', $data);

	if ( $this -> _check_capthca() ) {
        if ($this->form_validation->run() == FALSE)
		{
		    $this->session->set_flashdata('subscribe_msg', 'All fields are required . Please try again!');
		    redirect('welcome/index');
		}
		else
		{
		    $this->MSubscribers->createSubscriber();
		    $this->session->set_flashdata('subscribe_msg', 'Thanks for subscribing!');
		    redirect('welcome/index','refresh');
		}
      }else {
        $this->session->set_flashdata('subscribe_msg', 'Enter captcha . Please try again!');
	redirect('welcome/index');
      }
  }
  /**

   function _make_captcha()

      $query = $this -> db -> insert_string( 'captcha', $data );
      $this -> db -> query( $query );
    }else {
