This one of the hard jobs I have got to do. The main problems here was that i should make a shopping cart, which was then cancelled to more simple order form which is calculating the price and sending the letter to the company about the order.
Technologies Used: Codeigniter ,PHP,JavaScript, MYSQL
I was thinking on how to integrate phpThumb in CodeIgniter when I found a great answer on StackOverFlow.com

You can do this with the codeigniter image manipulation class.
Just create a helper with your image resize code, here is a basic example:
In the Helper
if ( ! function_exists('generate_image'))
{
function generate_image($img, $width, $height){
$obj =& get_instance();
$obj->load->library('image_lib');
$obj->load->helper('url');
$config['image_library'] = 'gd2';
$config['source_image'] = $img;
$config['new_image'] = './resources/images/img_tp/tn_img.png' ;
$config['width'] = $width;
$config['height'] = $height;
$obj->image_lib->initialize($config);
$obj->image_lib->resize();
return $config['new_image'];
}
}
Name as you wish and ensure to load the helper in your controller constructer.
Then in your view:
; ?>)
You can create a set of functions in the helper to perform different manipulation tasks and use them directly in your view using this method.
Here is the image manipulation documentation. http://codeigniter.com/user_guide/libraries/image_lib.html

Hi there.. I am not sleeping and searching for a good library to use . I am looking a multipurpose cache library for my social network made on codeigniter. So Now question about the scaling stands out and I am gonna to integrate some memcache .
So will do parallel list of all found libs. Maybe you will need it.
Add some more in comments if you know
Hi there who is making nice web-sites on Codeigniter. I like this framework. But I think it has some lack of standard. Really, I am not kidding. It would be great to have a standard of addon development, so that after when you share your code, the person who wants to use it would need to make 3 main steps.
1) Run mysql query from /addon_folder/install.sql
2)read /addon_folder/readme.txt
3)upload /addon_folder/application to the /system folder of his web-site or wherever the application folder he put , and don’t worry that anything will be overwritten
4) in case there should be any hacking made to the system files, like config.php, routes.php or else , ther should be very well described
/addon_folder/hackit.txt you do what is written, and yummy!
5) YOU GO to mysite.com/addon/ and feel happy! Everything should work!
I will add the rules step by step here. Your comments will be very appreciated
So I am begining to add .
1) The addon should have DBAD License (Don’t Be A Dick)
It’s Simple like magic. How? Just one line
$this->db->insert_id();
Note: Helper uses php php function mysql_insert_id
Note2:
Retrieves the ID generated for an AUTO_INCREMENT column by the previous query (usually INSERT).
Have Fun.
Итак у вас встал… нет не то… Вопрос встал.. Как показать видео на сайте? Притом давая возможности юзерам добавлять свои видео в виде линка к видео? Без проблем..
Качаем вот отсюда
http://wiki.codeigniter.ch/wiki/ci-wiki/OEmbed-Library
Библиотеку OEMBED для codeigniter.
Привет… Тебе наверное понадобился правильный или частичний Кешинг для CI?Ну Скажем вам надо частично скешировать ваш код для далнейших действий. Тогда не ломайте голову!.
Качаем сначала KhCache (http://codeigniter.com/forums/viewthread/69843/) от Khaosа.
1. Инсталл
Кидаем его в папку /application/libraries/
И начинаем юзать.
Если захотите переписать дефолтовые значения , те параметры библиотеки, то в папке /application/config создаем Khaos.php
И в нем пишем
$config['cache'] = array('container' => 'File',
'ttl' => 3600,
'File' => array('store' => BASEPATH.'cache/',
'auto_clean' => 10,
'auto_clean_life' => 3600,
'auto_clean_all' => false));
Все думаю понятно. Если захоите вместо контейнера File использовать скажем XCache Надо немножко помудить
с библиотекой
А в конфиге Написать так например
$config['cache'] = array('container' => 'APC');
Для чего отвечают отдельные ключи в массиве?
auto_clean - By default there is a 1 in 10 chance of the cache dir being cleaned, set to false to disable.
auto_clean_life - Files older than this will be removed.
auto_clean_all - By default only cache files prefixed with khcache_ are removed set to true to have khcache clean the entire directory
