How to add a new model<\/h2>\n
    \n
  1. Create the models folder<\/strong>\n

    If you haven\u2019t already, you will need to create the models<\/strong> folder. This is where our model<\/em> files will go. In our testing, we created:
    \n\/components\/com_helloworld\/models<\/span><\/p><\/li>\n

  2. Create <view>.php within models folder<\/strong>\n

    Each component view can have a corresponding model. In this tutorial we are creating a model for our helloworld<\/span> view, so we will be creating<\/p>\n

    \/components\/com_helloworld\/models\/helloworld.php<\/span><\/p>\n

    In this file, place the following code:<\/p>\n

    <?php \/\/ No direct access to this file defined('_JEXEC') or die('Restricted access');   \/\/ import Joomla modelitem library jimport('joomla.application.component.modelitem');   \/**  * HelloWorld Model  *\/ class HelloWorldModelHelloWorld<\/span> extends JModelItem {         \/**          * @var string msg          *\/         protected $msg;           \/**          * Get the message          * @return string The message to be displayed to the user          *\/         public function getMsg()          {                 if (!isset($this->msg))                  {                         $this->msg = 'This message has been brought to you by the hello world model getMsg function.';                 }                 return $this->msg;         } }<\/pre>\n<\/li>\n
  3. Update your view.html.php file to call the getMsg() function<\/strong>\n
    In our components\/com_helloworld\/views\/helloworld\/view.html.php<\/span><\/u> file,
    \nwe originally created the \u201cHello World<\/em>\u201d message via the following line:<\/p>\n
    $this->msg = 'Hello World<\/span>';<\/pre>\n
    We will replace this line of code with the following:<\/p>\n
    $this->msg = $this->get('Msg');<\/pre>\n
    The view.html.php<\/em> file will now look like the following:<\/p>\n
    <?php \/\/ No direct access to this file defined('_JEXEC') or die('Restricted access');   \/\/ import Joomla view library jimport('joomla.application.component.view');   \/**  * HTML View class for the HelloWorld Component  *\/ class HelloWorldViewHelloWorld extends JViewLegacy {         \/\/ Overwriting JView display method         function display($tpl = null)          {                 \/\/ Assign data to the view                 $this->msg = $this->get('Msg');<\/span>                                  \/\/ Display the view                 parent::display($tpl);         } }<\/pre>\n<\/li>\n<\/ol>\n
    Our new model in action<\/h2>\n
    As you can see in the screenshot below, our new model comes into play when our view calls one of the model\u2019s functions.<\/p>\n\n\n\n\n
    View<\/th>\nWhen our view<\/strong> calls<\/td>\n$this->get<\/span>(\u2018Msg<\/span>\u2018);<\/td>\n<\/tr>\n
    Model<\/th>\n\u2026 the following fuction is run in our model<\/strong>:<\/td>\nget<\/span>Msg<\/span>()<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
