在主页上添加此代码以显示产品并注释旧代码：

<?php echo $this->getLayout()->createBlock('manufacturer/manufacturer')->setProduct($_product)->setTemplate('manufacturer/product_manufacturer.phtml')->toHtml(); ?>

告诉我们您如何调用该方法。毗湿奴，请提供更多详细信息……我只是从链接中添加了新的扩展名，您在哪个页面上遇到此错误？主页或产品列表页或产品视图页。。。在主页上是指index.php，当我在安装后再次刷新页面时，此扩展不工作意味着您得到的错误是什么，或者日志文件中的错误是什么？？？
