介紹

• 本教學是 開發Joomla! 3.x MVC 元件 系列文章的一部分，閱讀本文之前，您應該先看過前面幾篇文章。

In this step we provide the ability for administrator to control the display of the category on the front end. We'll do this by specifying a global configuration parameter which can be set to Show or Hide, but also allow the administrator to override this setting on an individual Helloworld message basis. To enable this, we'll introduce a params field in the database record, which will be a string in JSON format (as is common in many Joomla core components), and we'll need to change the accompanying code to handle this.

您可以觀賞和此步驟教學有關的影片 Step 13. 新增設定介面.

新增設定參數

The Joomla framework allows the use of parameters stored in each component. With your favourite file manager and editor, put a file admin/config.xml file containing these lines:

admin/config.xml

<?xml version="1.0" encoding="utf-8"?>
<config>
	<fieldset
		name="greetings"
		label="COM_HELLOWORLD_CONFIG_GREETING_SETTINGS_LABEL"
		description="COM_HELLOWORLD_CONFIG_GREETING_SETTINGS_DESC"
	>
		<field
			name="show_category"
			type="radio"
			label="COM_HELLOWORLD_HELLOWORLD_FIELD_SHOW_CATEGORY_LABEL"
			description="COM_HELLOWORLD_HELLOWORLD_FIELD_SHOW_CATEGORY_DESC"
			default="0"
		>
			<option value="0">JHIDE</option>
			<option value="1">JSHOW</option>
		</field>
	</fieldset>
</config>

This file will be read by the com_config component of the Joomla core. For the moment, we defined only one parameter: is the category title displayed or not in the frontend.

The best way to set the parameters is to put a Preferences button in a toolbar.

With your favourite editor, put these lines in admin/views/helloworlds/view.html.php.

admin/views/helloworlds/view.html.php

<?php

// 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 application
		$app = JFactory::getApplication();
		$context = "helloworld.list.admin.helloworld";
		// Get data from the model
		$this->items			= $this->get('Items');
		$this->pagination		= $this->get('Pagination');
		$this->state			= $this->get('State');
		$this->filter_order 	= $app->getUserStateFromRequest($context.'filter_order', 'filter_order', 'greeting', 'cmd');
		$this->filter_order_Dir = $app->getUserStateFromRequest($context.'filter_order_Dir', 'filter_order_Dir', 'asc', 'cmd');
		$this->filterForm    	= $this->get('FilterForm');
		$this->activeFilters 	= $this->get('ActiveFilters');

		// Check for errors.
		if (count($errors = $this->get('Errors')))
		{
			JError::raiseError(500, implode('<br />', $errors));

			return false;
		}

		// Set the submenu
		HelloWorldHelper::addSubmenu('helloworlds');

		// Set the toolbar and number of found items
		$this->addToolBar();

		// Display the template
		parent::display($tpl);

		// Set the document
		$this->setDocument();
	}

	/**
	 * Add the page title and toolbar.
	 *
	 * @return  void
	 *
	 * @since   1.6
	 */
	protected function addToolBar()
	{
		$title = JText::_('COM_HELLOWORLD_MANAGER_HELLOWORLDS');

		if ($this->pagination->total)
		{
			$title .= "<span style='font-size: 0.5em; vertical-align: middle;'>(" . $this->pagination->total . ")</span>";
		}

		JToolBarHelper::title($title, 'helloworld');

		JToolBarHelper::deleteList('', 'helloworlds.delete');
		JToolBarHelper::preferences('com_helloworld');
	}
	/**
	 * Method to set up the document properties
	 *
	 * @return void
	 */
	protected function setDocument() 
	{
		$document = JFactory::getDocument();
		$document->setTitle(JText::_('COM_HELLOWORLD_ADMINISTRATION'));
	}
}

Using configuration parameters as default value

We want to define this parameter individually on all HelloWorld data. With your favourite editor, put these lines into the admin/models/forms/helloworld.xml

admin/models/forms/helloworld.xml

<?xml version="1.0" encoding="utf-8"?>
<form
				addrulepath="/administrator/components/com_helloworld/models/rules"
>
	<fieldset
				name="details"
				label="COM_HELLOWORLD_HELLOWORLD_DETAILS"
	>
		<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 validate-greeting"
				validate="greeting"
				required="true"
				default=""
				/>
		<field
				name="catid"
				type="category"
				extension="com_helloworld"
				class="inputbox"
				default=""
				label="COM_HELLOWORLD_HELLOWORLD_FIELD_CATID_LABEL"
				description="COM_HELLOWORLD_HELLOWORLD_FIELD_CATID_DESC"
				required="true"
		>
			<option value="0">JOPTION_SELECT_CATEGORY</option>
		</field>
	</fieldset>
	<fields name="params">
		<fieldset
				name="params"
				label="JGLOBAL_FIELDSET_DISPLAY_OPTIONS"
		>
			<field
					name="show_category"
					type="list"
					label="COM_HELLOWORLD_HELLOWORLD_FIELD_SHOW_CATEGORY_LABEL"
					description="COM_HELLOWORLD_HELLOWORLD_FIELD_SHOW_CATEGORY_DESC"
					default=""
			>
				<option value="">JGLOBAL_USE_GLOBAL</option>
				<option value="0">JHIDE</option>
				<option value="1">JSHOW</option>
			</field>
		</fieldset>
	</fields>
</form>

We define the same parameter for each message with an additional value: Use global.

Note: The details fieldset now has a label too (the same that was set in the edit view before).

修改 SQL

Data now contains a new parameter: params. The SQL structure has to be modified. With your favourite editor, put these lines into admin/sql/install.mysql.utf8.sql:

admin/sql/install.mysql.utf8.sql

DROP TABLE IF EXISTS `#__helloworld`;

CREATE TABLE `#__helloworld` (
	`id`       INT(11)     NOT NULL AUTO_INCREMENT,
	`greeting` VARCHAR(25) NOT NULL,
	`published` tinyint(4) NOT NULL,
	`catid`	    int(11)    NOT NULL DEFAULT '0',
	`params`   VARCHAR(1024) NOT NULL DEFAULT '',
	PRIMARY KEY (`id`)
)
	ENGINE =MyISAM
	AUTO_INCREMENT =0
	DEFAULT CHARSET =utf8;

INSERT INTO `#__helloworld` (`greeting`) VALUES
('Hello World!'),
('Good bye World!');

With your favourite editor, put these lines into admin/sql/updates/mysql/0.0.13.sql:

admin/sql/updates/mysql/0.0.13.sql

ALTER TABLE `#__helloworld` ADD `params` VARCHAR(1024) NOT NULL DEFAULT '';

The TableHelloWorld has to be modified in order to deal with these parameters; they will be stored in a JSON format. We have to overload the bind method to convert the array of these parameters into a JSON string for saving in the database. With your favourite editor, put these lines into admin/tables/helloworld.php.

admin/tables/helloworld.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2018 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');

/**
 * Hello Table class
 *
 * @since  0.0.1
 */
class HelloWorldTableHelloWorld extends JTable
{
	/**
	 * Constructor
	 *
	 * @param   JDatabaseDriver  &$db  A database connector object
	 */
	function __construct(&$db)
	{
		parent::__construct('#__helloworld', 'id', $db);
	}
	/**
	 * Overloaded bind function
	 *
	 * @param       array           named array
	 * @return      null|string     null is operation was satisfactory, otherwise returns an error
	 * @see JTable:bind
	 * @since 1.5
	 */
	public function bind($array, $ignore = '')
	{
		if (isset($array['params']) && is_array($array['params']))
		{
			// Convert the params field to a string.
			$parameter = new JRegistry;
			$parameter->loadArray($array['params']);
			$array['params'] = (string)$parameter;
		}
		return parent::bind($array, $ignore);
	}
}

修改後台

The backend edit view has to display the options to the administrator. With your favourite editor, put these lines into the admin/views/helloworld/tmpl/edit.php file:

admin/views/helloworld/tmpl/edit.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2018 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');
JHtml::_('behavior.formvalidator');
?>
<form action="<?php echo JRoute::_('index.php?option=com_helloworld&layout=edit&id=' . (int) $this->item->id); ?>"
    method="post" name="adminForm" id="adminForm" class="form-validate">
	<div class="form-horizontal">
		<?php foreach ($this->form->getFieldsets() as $name => $fieldset): ?>
			<fieldset class="adminform">
				<legend><?php echo JText::_($fieldset->label); ?></legend>
				<div class="row-fluid">
					<div class="span6">
						<?php foreach ($this->form->getFieldset($name) 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>
		<?php endforeach; ?>
	</div>
	<input type="hidden" name="task" value="helloworld.edit" />
	<?php echo JHtml::_('form.token'); ?>
</form>

Note: The outer foreach retrieves all of the form fieldsets while the inner one gets the selected fieldset fields.
This is the result of the $this->form->getFieldsets() command:

Array
(
    [details] => stdClass Object
        (
            [name] => details
            [label] => COM_HELLOWORLD_HELLOWORLD_DETAILS
            [description] => 
        )

    [params] => stdClass Object
        (
            [name] => params
            [label] => JGLOBAL_FIELDSET_DISPLAY_OPTIONS
            [description] => 
        )

)

Modifying the frontend

The frontend has to be modified according to the new show_category parameter.

We have to modify the model:

• it has to merge global parameters and individual parameters
• it has to provide the category

With your favourite editor, put these lines into the site/models/helloworld.php file:

site/models/helloworld.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2018 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 JModelItem
{
	/**
	 * @var object item
	 */
	protected $item;

	/**
	 * Method to auto-populate the model state.
	 *
	 * This method should only be called once per instantiation and is designed
	 * to be called on the first call to the getState() method unless the model
	 * configuration flag to ignore the request is set.
	 *
	 * Note. Calling getState in this method will result in recursion.
	 *
	 * @return	void
	 * @since	2.5
	 */
	protected function populateState()
	{
		// Get the message id
		$jinput = JFactory::getApplication()->input;
		$id     = $jinput->get('id', 1, 'INT');
		$this->setState('message.id', $id);

		// Load the parameters.
		$this->setState('params', JFactory::getApplication()->getParams());
		parent::populateState();
	}

	/**
	 * 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);
	}

	/**
	 * Get the message
	 * @return object The message to be displayed to the user
	 */
	public function getItem()
	{
		if (!isset($this->item)) 
		{
			$id    = $this->getState('message.id');
			$db    = JFactory::getDbo();
			$query = $db->getQuery(true);
			$query->select('h.greeting, h.params, c.title as category')
				  ->from('#__helloworld as h')
				  ->leftJoin('#__categories as c ON h.catid=c.id')
				  ->where('h.id=' . (int)$id);
			$db->setQuery((string)$query);
		
			if ($this->item = $db->loadObject()) 
			{
				// Load the JSON string
				$params = new JRegistry;
				$params->loadString($this->item->params, 'JSON');
				$this->item->params = $params;

				// Merge global params with item params
				$params = clone $this->getState('params');
				$params->merge($this->item->params);
				$this->item->params = $params;
			}
		}
		return $this->item;
	}
}

The view has to ask the model for the category. With your favourite editor, put these lines into the site/views/helloworld/view.html.php

site/views/helloworld/view.html.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2018 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');

/**
 * HTML View class for the HelloWorld Component
 *
 * @since  0.0.1
 */
class HelloWorldViewHelloWorld 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)
	{
		// Assign data to the view
		$this->item = $this->get('Item');

		// Check for errors.
		if (count($errors = $this->get('Errors')))
		{
			JLog::add(implode('<br />', $errors), JLog::WARNING, 'jerror');

			return false;
		}

		// Display the view
		parent::display($tpl);
	}
}

The layout can now display correctly the category or not. With your favourite editor, put these lines into site/views/helloworld/tmpl/default.php

site/views/helloworld/tmpl/default.php

<?php
/**
 * @package     Joomla.Administrator
 * @subpackage  com_helloworld
 *
 * @copyright   Copyright (C) 2005 - 2018 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');
?>
<h1><?php echo $this->item->greeting.(($this->item->category and $this->item->params->get('show_category'))
                                      ? (' ('.$this->item->category.')') : ''); ?>
</h1>

Adding some translation strings

Some strings have to be added in the admin/language/en-GB/en-GB.com_helloworld.ini file:
