部分系统常用方法：

 

获取objectManager

技术分享图片 
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
View Code

用这个objectManager方法能调用所有类，无需在构造函数里定义。

DataObject是所有Model的基类

技术分享图片 
$row = new \Magento\Framework\DataObject();
$row->setData($key, $value);
$row->getData($key);
$row->hasData($key);
$row->unsetData();
$row->toXml();
$row->toJson();
$row->debug();
View Code

Session

技术分享图片 
$session = $objectManager->get(‘Magento\Framework\Session\Storage‘);
$session->setXxxx($value);
$session->getXxxx();
$session->hasXxxx();
$session->unsXxxx();
View Code

cache

技术分享图片 
// save
$this->cache = $context->getCache();
$this->cache->save(\Zend_Json::encode($data), self::CACHE_PREFIX . $key, [], $lifeTime);

// load
$jsonStr = $this->cache->load(self::CACHE_PREFIX . $cacheKey);
if (strlen($jsonStr)) {
    $this->cachedData = \Zend_Json::decode($jsonStr);
}
View Code

判断是否首页

技术分享图片 
// in action
if($this->_request->getRouteName() == ‘cms‘ && $this->_request->getActionName() == ‘index‘) {
    // is home
}
View Code

Registry 用于内部传递临时值

技术分享图片 
/* @var \Magento\Framework\Registry $coreRegistry */
$coreRegistry = $this->_objectManager->get(‘Magento\Framework\Registry‘);
// 存储值
$coreRegistry->register(‘current_category‘, $category);
// 提取值
$coreRegistry->registry(‘current_category‘);
View Code

获取当前店铺对象

技术分享图片 
$store = $objectManager->get( ‘Magento\Store\Model\StoreManagerInterface‘ )->getStore();
View Code

提示信息

技术分享图片 
// \Magento\Framework\App\Action\Action::execute()
$this->messageManager->addSuccessMessage(__(‘You deleted the event.‘));
$this->messageManager->addErrorMessage(__(‘You deleted the event.‘));
return $this->_redirect ( $returnUrl );
log (support_report.log)
\Magento\Framework\App\ObjectManager::getInstance()
    ->get( ‘\Psr\Log\LoggerInterface‘ )->addCritical( ‘notice message‘, [
        ‘order_id‘ => $order_id,
        ‘item_id‘ => $item_id
        // ...
    ]);
View Code

保存customer自定义属性

比如我新建了一个customer属性叫new_register_promocode。

技术分享图片 
$customer = $objectManager->get(‘\Magento\Customer\Model\Customer‘)->load($customer->getId());
                $customerDataModel = $customer->getDataModel();
                $customerDataModel->setCustomAttribute(‘new_register_promocode‘,null);
                $customer->updateData($customerDataModel);
                $customer->save();
View Code

获取当前页面 URL

技术分享图片 
$currentUrl = $objectManager->get( ‘Magento\Framework\UrlInterface‘ )->getCurrentUrl();
View Code

技术分享图片 
$url = $objectManager->get( ‘Magento\Store\Model\StoreManagerInterface‘ )->getStore()->getUrl( ‘xxx/xxx/xxx‘ );
View Code

    $storeManager->getStore($store_id)->getBaseUrl();
}
View Code

获取产品属性的label

比如产品属性color，我后台设置了中文label为颜色。
用下面的代码可以获取属性color的label

$_attributeLabel = $_product->getResource()->getAttribute($_code)->getStoreLabel();

获取产品属性option的label

比如产品属性color,是dropdown类型的，某个option值为XL.
前台直接$product->getColor(),得到的是个数字，而不是我设置的‘XL‘。
用下面的代码可以获取option的label

 * @param $customerGroupId
 * @return mixed
 */
public function getCatalogPriceRuleFromProduct($productId, $customerGroupId)
{
    /**
     * @var \Magento\Catalog\Model\ProductFactory
     */
    $product = $this->_objectManager->create(‘\Magento\Catalog\Model\ProductFactory‘)->create()->load($productId);

    $storeId = $product->getStoreId();
    $store = $this->_store_manager->getStore($storeId);
    $websiteId = $store->getWebsiteId();
    /**
     * @var \Magento\Framework\Stdlib\DateTime\DateTime
     */
    $date = $this->_objectManager->create(‘\Magento\Framework\Stdlib\DateTime\DateTime‘);
    $dateTs = $date->gmtDate();

    /**
     * @var \Magento\CatalogRule\Model\ResourceModel\Rule
     */
    $resource = $this->_objectManager->create(‘\Magento\CatalogRule\Model\ResourceModel\Rule‘);

    $rules = $resource->getRulesFromProduct($dateTs, $websiteId, $customerGroupId, $productId);

    return $rules;
}

获得实际的折扣金额:

技术分享图片 
/*
* @var \Magento\CatalogRule\Model\RuleFactory

$rule = $this->_objectManager->create(‘\Magento\CatalogRule\Model\RuleFactory‘)->create();
$discountAmount = $rule->calcProductPriceRule($product,$product->getPrice());
View Code

获取当前页面的控制器/action等

在phtml和controller里调用

技术分享图片 
echo $controllerName = $this->getRequest()->getControllerName();
echo $actionName = $this->getRequest()->getActionName();
echo $routeName = $this->getRequest()->getRouteName();
echo $moduleName = $this->getRequest()->getModuleName();
View Code

过滤处理可视化编辑器内容

主要把标签和变量转换。
比如{{store}},{{view}},{{media}}等

技术分享图片 
$description = $product->getDescription();
$_templateProcessor = $this->_objectManager->get(‘Magento\Catalog\Helper\Data‘)->getPageTemplateProcessor();
$description = $_templateProcessor->filter($description);
View Code
