1.8 Hello World添加menu

本节讲述如何获得一个指向特定组件的链接。

（1）在default.php的统计目录下添加文件default.xml ,这就可以使joomla 能够识别default.php为一个菜单项。

site/views/helloworld/tmpl/default.xml

<?xml version="1.0" encoding="utf-8"?>
<metadata>
    <layout title="COM_HELLOWORLD_HELLOWORLD_VIEW_DEFAULT_TITLE">
        <message>
            <![CDATA[COM_HELLOWORLD_HELLOWORLD_VIEW_DEFAULT_DESC]]>
        </message>
    </layout>
</metadata>

此刻，在管理员接口中字符串不会被转换，在后面的章节中我们会看到转换时如何执行的。

（2）修改helloworld.xml并且改变版本号

<?xml version="1.0" encoding="utf-8"?>
<extension type="component" version="2.5.0" method="upgrade">
 
    <name>Hello World!</name>
    <!-- The following elements are optional and free of formatting constraints -->
    <creationDate>November 2009</creationDate>
    <author>John Doe</author>
    <authorEmail>john.doe@example.org</authorEmail>
    <authorUrl>http://www.example.org</authorUrl>
    <copyright>Copyright Info</copyright>
    <license>License Info</license>
    <!--  The version string is recorded in the components table -->
    <version>0.0.3</version>
    <!-- The description is optional and defaults to the name -->
    <description>Description of the Hello World component ...</description>
 
    <update> <!-- Runs on update; New in 2.5 -->
        <schemas>
            <schemapath type="mysql">sql/updates/mysql</schemapath>
        </schemas>
    </update>
 
    <!-- Site Main File Copy Section -->
    <!-- Note the folder attribute: This attribute describes the folder
        to copy FROM in the package to install therefore files copied
        in this section are copied from /site/ in the package -->
    <files folder="site">
        <filename>index.html</filename>
        <filename>helloworld.php</filename>
        <filename>controller.php</filename>
        <folder>views</folder>
    </files>
 
    <administration>
        <!-- Administration Menu Section -->
        <menu>Hello World!</menu>
        <!-- Administration Main File Copy Section -->
        <!-- Note the folder attribute: This attribute describes the folder
            to copy FROM in the package to install therefore files copied
            in this section are copied from /admin/ in the package -->
        <files folder="admin">
            <!-- Admin Main File Copy Section -->
            <filename>index.html</filename>
            <filename>helloworld.php</filename>
            <!-- SQL files section -->
            <folder>sql</folder>
        </files>
    </administration>
 
</extension>

最后打包安装，如同前面所说。
