Joomla 3.x_component如何打包安装和卸载

本文是component的打包，与component安装和卸载相关的内容。component包内与安装卸载相关的文件就只有两个，script.php和componentname.xml。script.php是安装或卸载时运行的脚本，componentname.xml是指导安装如何进行的和包含哪些安装文件。下面就一步步建一个基本component包，例子的component名为com_example：

（1）example.xml文件，注意的是，每个文件夹下一定要有个index.html，防止目录浏览。

<?xml version="1.0" encoding="utf-8"?><extension type="component" version="3.0" method="upgrade">    <!-- component的基本信息 -->  <name>COM_EXAMPLE</name> <!-- 大写表明该项为多语言翻译项，在language的ini文件中 -->  <author>Laixiang Wen</author>  <version>1.0</version>  <creationDate>Apirl 4, 2013</creationDate>  <copyright>Copyright (C) 2013 Fighting Bull Studio.

（2）script.php文件，类名一定要为com_componentnameInstallerScript，这里是com_exampleInstallerScript

<?php// No direct access to this filedefined('_JEXEC') or die('Restricted access');/** * Script file of EXAMPLE component */class com_exampleInstallerScript{/** * method to install the component * * @return void */function install($parent){// $parent is the class calling this method//$parent->getParent()->setRedirectURL('index.php?option=com_example');}/** * method to uninstall the component * * @return void */function uninstall($parent){// $parent is the class calling this methodecho '<p>' . JText::_('COM_EXAMPLE_UNINSTALL_TEXT') . '</p>';}/** * method to update the component * * @return void */function update($parent){// $parent is the class calling this methodecho '<p>' . JText::sprintf('COM_EXAMPLE_UPDATE_TEXT', $parent->get('manifest')->version) . '</p>';}/** * method to run before an install/update/uninstall method * * @return void */function preflight($type, $parent){// $parent is the class calling this method// $type is the type of change (install, update or discover_install)echo '<p>' . JText::_('COM_EXAMPLE_PREFLIGHT_' . $type . '_TEXT') . '</p>';}/** * method to run after an install/update/uninstall method * * @return void */function postflight($type, $parent){// $parent is the class calling this method// $type is the type of change (install, update or discover_install)echo '<p>' . JText::_('COM_EXAMPLE_POSTFLIGHT_' . $type . '_TEXT') . '</p>';}}
