Php 如何从joomla中的模块参数获取数据

我正在构建一个joomla 2.5模块，我想从模块参数访问数据传递，但我得到以下错误：致命错误：对非对象调用成员函数get（） 我的代码如下：

helper.php mod_feedGrabber.php mod_feedGrabber.xml

mod_feedGrabber.xml
mod_feedGrabber.php
index.html
helper.php
tmpl/default.php
tmpl/index.html
tmpl

default.php

我看到提供的代码的主要问题是没有将
$params
传递给助手函数。应该是这样的：

defined( '_JEXEC' ) or die( 'Restricted access' );
$sitebase = JPATH_BASE;
$doc =& JFactory::getDocument();

// Include the syndicate functions only once
require_once( dirname(__FILE__).DS.'/helper.php' );
$feed = new modFeedGrabber();
$url = $feed->feedurl($params);
require( JModuleHelper::getLayoutPath( 'mod_feedGrabber' ) );

        <fields name="params">
            <fieldset name="basic">
                <field
                    name="feedUrl"
                    type="url"
                    size="50"
                    label="Feed URL"
                    description="Enter the url of the feed"
                />
            </fieldset>
        </fields>
    </config>
</extension>

此外，您的XML无效，因为它缺少
字段集
和
字段
标记的结束标记。应该是这样的：

defined( '_JEXEC' ) or die( 'Restricted access' );
$sitebase = JPATH_BASE;
$doc =& JFactory::getDocument();

// Include the syndicate functions only once
require_once( dirname(__FILE__).DS.'/helper.php' );
$feed = new modFeedGrabber();
$url = $feed->feedurl($params);
require( JModuleHelper::getLayoutPath( 'mod_feedGrabber' ) );
