3 - Add an item

Now you may want to add an item to the database

The "new" button in cars list page will redirect you to the edit page.

administrator / components / com_dealer / car / view.html.php

<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');


/**
 * View file
 */
class DealerViewCar extends JViewLegacy
{

    /**
     * The JForm object
     *
     * @var  JForm
     */
    protected $form;

    /**
     * The active item
     *
     * @var  object
     */
    protected $item;

    /**
     * The model state
     *
     * @var  object
     */
    protected $state;

    public function display($tpl = null) 
    {
        $form = null;
        $this->item  = $this->get('Item');        

        try
        {
            $form = $this->get('Form');
        }
        catch (Exception $e)
        {
            JFactory::getApplication()->enqueueMessage($e->getMessage(), 'error');

            return false;
        }

        // Bind the form to the data.
        if ($form && $this->item)
        {
            $form->bind($this->item);
        }

        $this->form = &$form;

        // trigger plugin
        $this->prms = new stdClass();
        JPluginHelper::importPlugin( Bp::getComponent() );
        $dispatcher = JEventDispatcher::getInstance();
        $results = $dispatcher->trigger( 'on'.ucfirst(Bp::getComponent()).ucfirst(Bp::getView()).'DataPrepare'
                                            , array( &$this->form, &$this->prms ) );
        
        // buttons and page title
        BpForm::admAddItemButtons(Bp::get('my_key_id', 0));

        parent::display($tpl);
        
    }

}
// pure php no tag

As you can easily guess, at this point, you can copy and paste the whole script for every item view in your component, changing the class's name and "my_key_id" accordingly with the ID key of your database table.

The method appends the (most commonly used) buttons:

• apply
• save
• save2new
• cancel

If you are thinking that you can easily disable some button(s) passing to the method an array of instructions... you already learned how to use the BPLibrary!

As you can see the learning curve is really superfast!
