Model-View-Controller Component - Part 4 Creating an Administrator Interface

an Administrator Interface Introduction In the first three tutorials, we have developed a MVC component that retrieves its data from a table in the database. Currently, there is no way to add data to the database except to do it manually using another tool. In this tutorial, we will develop an administrator section for our component which will make it possible to manage the entries in the database. Creating the Basic Framework The basic framework of the administrator panel is very similar to the site portion. The main entry point for the administrator section of the component is admin.hello.php.

The default controller is also called controller.php and this file is identical to the default controller in the site portion, with the exception that the controller is named HellosController instead of HelloController.

In this second part of the tutorial we will demonstrate how to move this out of the view and into a model. In future tutorials we will demonstrate the power and flexibility that this design pattern provides. Creating the Model The concept of model gets its name because this class is intended to represent (or ‘model’) some entity. In our case, our first model will represent a ‘hello’, or a greeting. This is in line with our design thus far, because we have one view (’hello’), which is a view of our greeting. The naming convention for models in the Joomla! framework is that the class name starts with the...

Ubuntu LAMP Server

Get this content from link http://www.zaphu.com/2007/08/07/ubuntu-lamp-server-setup-guide-with-desktop-gui/ Step 1: Install Ubuntu Server Edition with LAMP server components. Download the disk image (*iso) for Ubuntu Server Edition (currently version 8.04 Hardy Heron) and burn it to a CD. Ensure that your BIOS is configured to boot from the CD-ROM drive. Restart with the Ubuntu disk in the drive and the machine should boot into the Ubuntu installation shell. If you would like to configure a static IP address, select F6 - Other Options and enter netcfg/disable_dhcp=true at the end of the options string, and the install script will prompt you for network information during the installation. Otherwise, the static IP must be configured post installation as per the second part of step 2 below, and your network will be automatically configured using DHCP (as long as DHCP is enabled on your router). In either scenario, you must enter a hostname when prompted. As you work through the installat...
