Description

If you’re a PHP developer, you can build Rails-like applications without learning a new language by following the hands-on tutorials in Professional CodeIgniter. In this book, find an overview of MVC and agile technologies, model and schema for products, helpers and libraries, Ajax and Scriptaculous, and explanations of the creation of applications like content management, blogs, and forums. Follow the step-by-step instructions for building and perfecting each application with CodeIgniter, and you will learn how to avoid everyday problems that other reference manuals don’t address.

102Error in Code
the search() function contains this group of code:

if ($this->input->post('term')){
$search['results'] = $this->MProducts->search($this->input->post
('term');
}else{
...

The use of $search['results'] is incorrect, as it should be $data['results'] instead, like this:

if ($this->input->post('term')){
$data['results'] = $this->MProducts->search($this->input->post('term');
}else{
...

The code is correct in the downloadable zip archive. 		08/18/08
