将图像添加到joomla jtoolbar自定义链接按钮

你需要创建一个叫做 icon-32-export 有图像背景。

下面是一个例子:

<?php

// Add CSS class to the document, it's better to have it in external CSS document
$imgPath = JRoute::_('/administrator/templates/khepri/images/toolbar/icon-32-new.png');
JFactory::getDocument()->addStyleDeclaration(".icon-32-export { background: url($imgPath); }");

//
$bar = & JToolBar::getInstance('toolbar');
$url = JRoute::_('index.php?option=com_component&task=export&format=raw');
$bar->appendButton( 'Link', 'export', 'Export', $url);

?>
