如何从Joomla获取组件版本? [英] How to get component version from Joomla?

问题描述

是否有某种方法可以通过名称获取组件版本?我尝试了很多示例，但没有找到任何可行的示例. JComponentHelper::getParams('com_mycomponent')->get('version')之类的东西不起作用，因为它从jos_extensions.params行中检索值.我的组件版本仅在jos_extensions.manifest_cache行中...

Is there some method to get components version by it's name? I tried a lot of examples but didn't find any that would work. The thing like JComponentHelper::getParams('com_mycomponent')->get('version') doesn't work as it retrieves values from jos_extensions.params row. My components version is only in jos_extensions.manifest_cache row...

推荐答案

您可以使用以下内容:

Joomla 2.5:

$parser = JFactory::getXMLParser('Simple');
$xml = JPATH_SITE .'/components/com_wrapper/wrapper.xml';
$parser->loadFile($xml);
$doc = $parser->document;
$element = $doc->getElementByPath('version');
$version = $element->data();

echo $version;

Joomla 3.x(平台13.3及更低版本)

$xml = JFactory::getXML(JPATH_SITE .'/components/com_wrapper/wrapper.xml');
$version = (string)$xml->version;

echo $version;

Joomla 3.2 +:

getXML.而是使用 SimpleXML

很明显，这是包装器组件的一个示例，因此请将路径更改为适合您需要的任何内容.

Obviously this is an example for the Wrapper component so change the paths to whatever suits your needs.
