Introduction

This tutorial is part of the Developing a MVC Component for Joomla! 3.2 tutorial. You are encouraged to read the previous parts of the tutorial before reading this.

Adding a toolbar

In Joomla, the administrator interacts generally with components through the use of a toolbar. In the file admin/views/helloworlds/view.html.php put this content. It will create a basic toolbar and a title for the component.

The arguments used in, for example, JToolBarHelper::addNew is used to set a controller instance which will be used after button is clicked. Further details below in the adding specific controllers section.

admin/views/helloworlds/view.html.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2015 Open Source Matters, Inc. All rights reserved.
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */
 
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
 
/**
 * HelloWorlds View
 *
 * @since  0.0.1
 */
class HelloWorldViewHelloWorlds extends JViewLegacy
{
	/**
	 * Display the Hello World view
	 *
	 * @param   string  $tpl  The name of the template file to parse; automatically searches through the template paths.
	 *
	 * @return  void
	 */
	function display($tpl = null)
	{
		// Get data from the model
		$this->items		= $this->get('Items');
		$this->pagination	= $this->get('Pagination');
 
		// Check for errors.
		if (count($errors = $this->get('Errors')))
		{
			JError::raiseError(500, implode('<br />', $errors));
 
			return false;
		}
 
		// Set the toolbar
		$this->addToolBar();
 
		// Display the template
		parent::display($tpl);
	}
 
	/**
	 * Add the page title and toolbar.
	 *
	 * @return  void
	 *
	 * @since   1.6
	 */
	protected function addToolBar()
	{
		JToolBarHelper::title(JText::_('COM_HELLOWORLD_MANAGER_HELLOWORLDS'));
		JToolBarHelper::addNew('helloworld.add');
		JToolBarHelper::editList('helloworld.edit');
		JToolBarHelper::deleteList('', 'helloworlds.delete');
	}
}

You can find other classic backend actions in the administrator/includes/toolbar.php file of your Joomla installation.

Since the view can perform some actions, we have to add some input data. With your favorite file manager and editor, put in the file admin/views/helloworlds/tmpl/default.php

admin/views/helloworlds/tmpl/default.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2015 Open Source Matters, Inc. All rights reserved.
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */
 
// No direct access to this file
defined('_JEXEC') or die('Restricted Access');
?>
<form action="index.php?option=com_helloworld&view=helloworlds" method="post" id="adminForm" name="adminForm">
	<table class="table table-striped table-hover">
		<thead>
		<tr>
			<th width="1%"><?php echo JText::_('COM_HELLOWORLD_NUM'); ?></th>
			<th width="2%">
				<?php echo JHtml::_('grid.checkall'); ?>
			</th>
			<th width="90%">
				<?php echo JText::_('COM_HELLOWORLD_HELLOWORLDS_NAME') ;?>
			</th>
			<th width="5%">
				<?php echo JText::_('COM_HELLOWORLD_PUBLISHED'); ?>
			</th>
			<th width="2%">
				<?php echo JText::_('COM_HELLOWORLD_ID'); ?>
			</th>
		</tr>
		</thead>
		<tfoot>
			<tr>
				<td colspan="5">
					<?php echo $this->pagination->getListFooter(); ?>
				</td>
			</tr>
		</tfoot>
		<tbody>
			<?php if (!empty($this->items)) : ?>
				<?php foreach ($this->items as $i => $row) :
					$link = JRoute::_('index.php?option=com_helloworld&task=helloworld.edit&id=' . $row->id);
				?>
					<tr>
						<td><?php echo $this->pagination->getRowOffset($i); ?></td>
						<td>
							<?php echo JHtml::_('grid.id', $i, $row->id); ?>
						</td>
						<td>
							<a href="<?php echo $link; ?>" title="<?php echo JText::_('COM_HELLOWORLD_EDIT_HELLOWORLD'); ?>">
								<?php echo $row->greeting; ?>
							</a>
						</td>
						<td align="center">
							<?php echo JHtml::_('jgrid.published', $row->published, $i, 'helloworlds.', true, 'cb'); ?>
						</td>
						<td align="center">
							<?php echo $row->id; ?>
						</td>
					</tr>
				<?php endforeach; ?>
			<?php endif; ?>
		</tbody>
	</table>
	<input type="hidden" name="task" value=""/>
	<input type="hidden" name="boxchecked" value="0"/>
	<?php echo JHtml::_('form.token'); ?>
</form>

Adding specific controllers

Three actions have been added:

  • helloworlds.delete
  • helloworld.edit
  • helloworld.add

read more about subcontrollers...

These are compound tasks (controller.task). So two new controllers HelloWorldControllerHelloWorlds and HelloWorldControllerHelloWorld have to be coded.

admin/controllers/helloworlds.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2015 Open Source Matters, Inc. All rights reserved.
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
 
/**
 * HelloWorlds Controller
 *
 * @since  0.0.1
 */
class HelloWorldControllerHelloWorlds extends JControllerAdmin
{
	/**
	 * Proxy for getModel.
	 *
	 * @param   string  $name    The model name. Optional.
	 * @param   string  $prefix  The class prefix. Optional.
	 * @param   array   $config  Configuration array for model. Optional.
	 *
	 * @return  object  The model.
	 *
	 * @since   1.6
	 */
	public function getModel($name = 'HelloWorld', $prefix = 'HelloWorldModel', $config = array('ignore_request' => true))
	{
		$model = parent::getModel($name, $prefix, $config);
 
		return $model;
	}
}

admin/controllers/helloworld.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2015 Open Source Matters, Inc. All rights reserved.
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
 
/**
 * HelloWorld Controller
 *
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 * @since       0.0.9
 */
class HelloWorldControllerHelloWorld extends JControllerForm
{
}

Adding an editing view

With your favorite file manager and editor, put a file admin/views/helloworld/view.html.php containing:

admin/views/helloworld/view.html.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2015 Open Source Matters, Inc. All rights reserved.
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */
 
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
 
/**
 * HelloWorld View
 *
 * @since  0.0.1
 */
class HelloWorldViewHelloWorld extends JViewLegacy
{
	/**
	 * View form
	 *
	 * @var         form
	 */
	protected $form = null;
 
	/**
	 * Display the Hello World view
	 *
	 * @param   string  $tpl  The name of the template file to parse; automatically searches through the template paths.
	 *
	 * @return  void
	 */
	public function display($tpl = null)
	{
		// Get the Data
		$this->form = $this->get('Form');
		$this->item = $this->get('Item');
 
		// Check for errors.
		if (count($errors = $this->get('Errors')))
		{
			JError::raiseError(500, implode('<br />', $errors));
 
			return false;
		}
 
 
		// Set the toolbar
		$this->addToolBar();
 
		// Display the template
		parent::display($tpl);
	}
 
	/**
	 * Add the page title and toolbar.
	 *
	 * @return  void
	 *
	 * @since   1.6
	 */
	protected function addToolBar()
	{
		$input = JFactory::getApplication()->input;
 
		// Hide Joomla Administrator Main menu
		$input->set('hidemainmenu', true);
 
		$isNew = ($this->item->id == 0);
 
		if ($isNew)
		{
			$title = JText::_('COM_HELLOWORLD_MANAGER_HELLOWORLD_NEW');
		}
		else
		{
			$title = JText::_('COM_HELLOWORLD_MANAGER_HELLOWORLD_EDIT');
		}
 
		JToolBarHelper::title($title, 'helloworld');
		JToolBarHelper::save('helloworld.save');
		JToolBarHelper::cancel(
			'helloworld.cancel',
			$isNew ? 'JTOOLBAR_CANCEL' : 'JTOOLBAR_CLOSE'
		);
	}
}

This view will display data using a layout.

Put a file admin/views/helloworld/tmpl/edit.php containing

admin/views/helloworld/tmpl/edit.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2015 Open Source Matters, Inc. All rights reserved.
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */
 
// No direct access
defined('_JEXEC') or die('Restricted access');
 
?>
<form action="<?php echo JRoute::_('index.php?option=com_helloworld&layout=edit&id=' . (int) $this->item->id); ?>"
    method="post" name="adminForm" id="adminForm">
    <div class="form-horizontal">
        <fieldset class="adminform">
            <legend><?php echo JText::_('COM_HELLOWORLD_HELLOWORLD_DETAILS'); ?></legend>
            <div class="row-fluid">
                <div class="span6">
                    <?php foreach ($this->form->getFieldset() as $field): ?>
                        <div class="control-group">
                            <div class="control-label"><?php echo $field->label; ?></div>
                            <div class="controls"><?php echo $field->input; ?></div>
                        </div>
                    <?php endforeach; ?>
                </div>
            </div>
        </fieldset>
    </div>
    <input type="hidden" name="task" value="helloworld.edit" />
    <?php echo JHtml::_('form.token'); ?>
</form>

Adding a model and modifying the existing one

The HelloWorldViewHelloWorld view asks form and data from a model. This model has to provide a getTable, a getForm method and a loadData method (called from the JModelAdmin controller)

admin/models/helloworld.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2015 Open Source Matters, Inc. All rights reserved.
 * @license     GNU General Public License version 2 or later; see LICENSE.txt
 */
 
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
 
/**
 * HelloWorld Model
 *
 * @since  0.0.1
 */
class HelloWorldModelHelloWorld extends JModelAdmin
{
	/**
	 * Method to get a table object, load it if necessary.
	 *
	 * @param   string  $type    The table name. Optional.
	 * @param   string  $prefix  The class prefix. Optional.
	 * @param   array   $config  Configuration array for model. Optional.
	 *
	 * @return  JTable  A JTable object
	 *
	 * @since   1.6
	 */
	public function getTable($type = 'HelloWorld', $prefix = 'HelloWorldTable', $config = array())
	{
		return JTable::getInstance($type, $prefix, $config);
	}
 
	/**
	 * Method to get the record form.
	 *
	 * @param   array    $data      Data for the form.
	 * @param   boolean  $loadData  True if the form is to load its own data (default case), false if not.
	 *
	 * @return  mixed    A JForm object on success, false on failure
	 *
	 * @since   1.6
	 */
	public function getForm($data = array(), $loadData = true)
	{
		// Get the form.
		$form = $this->loadForm(
			'com_helloworld.helloworld',
			'helloworld',
			array(
				'control' => 'jform',
				'load_data' => $loadData
			)
		);
 
		if (empty($form))
		{
			return false;
		}
 
		return $form;
	}
 
	/**
	 * Method to get the data that should be injected in the form.
	 *
	 * @return  mixed  The data for the form.
	 *
	 * @since   1.6
	 */
	protected function loadFormData()
	{
		// Check the session for previously entered form data.
		$data = JFactory::getApplication()->getUserState(
			'com_helloworld.edit.helloworld.data',
			array()
		);
 
		if (empty($data))
		{
			$data = $this->getItem();
		}
 
		return $data;
	}
}

This model inherits from the JModelAdmin class and uses its loadForm method. This method searches for forms in the forms folder. With your favorite file manager and editor, put a file admin/models/forms/helloworld.xml containing:

admin/models/forms/helloworld.xml

<?xml version="1.0" encoding="utf-8"?>
<form>
	<fieldset>
		<field
				name="id"
				type="hidden"
				/>
		<field
				name="greeting"
				type="text"
				label="COM_HELLOWORLD_HELLOWORLD_GREETING_LABEL"
				description="COM_HELLOWORLD_HELLOWORLD_GREETING_DESC"
				size="40"
				class="inputbox"
				default=""
				/>
	</fieldset>
</form>

Note: COM_HELLOWORLD_HELLOWORLD_GREETING_LABEL and COM_HELLOWORLD_HELLOWORLD_GREETING_DESC are an alias for COM_HELLOWORLD_HELLOWORLD_FIELD_GREETING_LABEL and COM_HELLOWORLD_HELLOWORLD_FIELD_GREETING_DESC respectively. Here we are using different label and description to convey two different meanings in two different sections, but they can be easily kept equal.

Packaging the component

Content of your code directory

Create a compressed file of this directory or directly download the archive and install it using the extension manager of Joomla. You can add a menu item of this component using the menu manager in the backend.

helloworld.xml

<?xml version="1.0" encoding="utf-8"?>
<extension type="component" version="3.2.0" method="upgrade">
 
	<name>COM_HELLOWORLD</name>
