如何在自定义数据库中选择Magento中的单行以在块中显示？

Question

我不希望使用foreach通过多行的数组循环,因为我只上只显示筹划一个行和使用的变量.我在网上找不到这方面的信息.

什么行不通

    $param = $this->getRequest()->getParam('manufacturer');
    $extrabrand = Mage::getModel('brands/brands')->getCollection();
    $extrabrand->addFieldToFilter('attributelabelid', $param);
    //$extrabrand->setAttributelabelid($param);
    $extrabrand->load();

致命错误:在第20行的/home/desbest/public_html/clients/magentofull/app/design/frontend/default/default/template/Desbest_Brands/brand_info.phtml中调用未定义的方法Desbest_Brands_Model_Mysql4_Brands_Collection :: getDescription()

此外,没有EAV.

在没有看到代码brand_info.phtml的情况下很难说出问题是什么,但我的猜测是你正在使用该集合,$extrabrand就好像它是一个模型.试试这个

//get the parameter from the request
$param = $this->getRequest()->getParam('manufacturer');

//instantiate the brand/brand model, and use 
//its `getCollection` method to return a collection
//object
$collection = Mage::getModel('brands/brands')->getCollection();

//add the paramater as a filter
$collection->addFieldToFilter('attributelabelid', $param);

//get the first item of the collection (load will be called automatically)
$extrabrand = $collection->getFirstItem();

//look at the data in the first item
var_dump($extrabrand->getData());
