Question

您好我遇到从控制器传递变量到块的错误。我正在尝试搜索功能。

错误消息：

致命错误：在a上调用成员函数setCustomerRegistries（）非对象 E：\ XAMPP \ htdocs中\ magento2 \程序\代码\本地\千年发展目标\礼物登记\控制器\ SearchController.php 在第27行

控制器

<?php
class Mdg_Giftregistry_SearchController extends Mage_Core_Controller_Front_Action{

    public function indexAction(){
        $this->loadLayout();
        $this->renderLayout();
        return $this;
    }
    public function resultsAction(){
        $this->loadLayout();

        if ($searchParams = $this->getRequest()->getParam('search_params')) {

            $results = Mage::getModel('mdg_giftregistry/entity')->getCollection();

            if($searchParams['type']){
                $results->addFieldToFilter('type_id', $searchParams['type']);
            }

            if($searchParams['date']){
                $results->addFieldToFilter('event_date', $searchParams['date']);
            }

            if($searchParams['location']){
                $results->addFieldToFilter('event_location', $searchParams['location']);
            }
            $this->getLayout()->getBlock('mdg_giftregistry.search.results')->setCustomerRegistries($results);
        }

        $this->renderLayout();
        return $this;
    }


}

阻止

<?php
class Mdg_Giftregistry_Block_List extends Mage_Core_Block_Template
{
    public function getCustomerRegistries()
    {
        $collection = null;
        $currentCustomer = Mage::getSingleton('customer/session')->getCustomer();
        if($currentCustomer)
        {
            $collection = Mage::getModel('mdg_giftregistry/entity')->getCollection()
                ->addFieldToFilter('customer_id', $currentCustomer->getId());
        }
        return $collection;
    }
}

模板

<?php
$_collection = $this->getCustomerRegistries();
$helper = Mage::helper('mdg_giftregistry')
?>
<div class="customer-list">
    <?php if(!$_collection->count()): ?>
        <h2><?php echo $this->__('You have no registries.') ?></h2>

试试这个解决方案。改变这一行

$this->getLayout()->getBlock('mdg_giftregistry.search.results')->setCustomerRegistries($results);

到

$this->getLayout()->getBlock('giftregistry.results')->setCustomerRegistries($results);

如何将变量从Controller传递到Block
