在magento品牌名称购买

Question

这是brand.php文件，目录为local / Vilpjsc / brand / Block。我想在主页上显示带有logo（图像）sholud的品牌名称。但是我收到错误即致命错误：调用成员函数第25行的/var/www/magentodemo/app/code/local/Vilpjsc/Brand/Block/Brand.php中的非对象上的getCollection（）

<?php

        $this->setData('brand', Mage::registry('brand'));

    }

    return $this->getBrand()->getCollection()->setPageSize(12)->addFilter('status', '1');
