Question

如果有可用的更新，Joomla会在登录后端后进行检查。如果是，您可以在点击“查看更新”时看到概述。但是我想显示一条关于我开发的扩展程序更新的类似消息（＆＃39;有可用的更新＆＃39;）。我尝试了一些东西，但到目前为止我还没有管理。有什么建议吗？

这是我为我的组件所遵循的代码。您可以在views-＆gt; tmpl-＆gt; default.php文件中使用相同的文件

<?php $user = JFactory::getUser();  ?>

<div class="UpdatesPage" style="margin-top: 8px">
<?php 
$xml = JFactory::getXML(JPATH_ADMINISTRATOR .'/components/com_mycomponent/manifest.xml');//Path to your existing manifest file. 
$existingversion = (string)$xml->version;

$url = 'http://example.com/downloads/mycomponent.xml';
//$url is path to your xml file which stores the latest version.
$ch = curl_init($url);//Execute curl and get the xml data available in my server

curl_setopt($ch, CURLOPT_NOBODY, true);
curl_exec($ch);
$retcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
// 400 means not found, 200 means found.
curl_close($ch);
if($retcode == 200){
$xml2 = JFactory::getXML($url,true);
  $latestversion = $xml2->update->version;
} else {
  $latestversion = "";
}

?>
<h2>Version Update</h2>
<?php
if ( version_compare($latestversion, $existingversion) > 0) {
    echo "<span style='color:#AFA;text-align:center;'>The version installed is ".$existingversion."</span><br />";
    echo "<span style='color:red;text-align:center;'>The latest version is ".$latestversion."</span><br />";    

} else {
    echo "<span style='color:green;text-align:center;'>You have the Latest version</span>"; 
}
?>
</div>

这是我服务器中的xml文件，我更新它，以便我的组件用户可以看到他们何时访问我的组件更新页面

<?xml version="1.0" encoding="utf-8"?>
<updates>
    <update>
        <name><![CDATA[My Component]]></name>
        <description><![CDATA[Download Component]]></description>

        <downloads>
           <downloadurl type="full" format="zip">https://example.com/index.php?option=com_mycomponent</downloadurl>
       </downloads>
