Redirect to controller from observer in magento2<\/p>\n\n\n\n
Here I am going to explain, how you redirect to a controller\/action from the observer.<\/p>\n\n\n\n
Step 1. We need to create an events.xml file inside the etc\/frontend\/ then write the below code inside this file.<\/p>\n\n\n\n
<event name="controller_action_predispatch_review">\n <observer name="catalog_review_enabled" instance="Company\\Module\\Observer\\CustomObserver" \/>\n<\/event><\/pre>\n\n\n\nStep 2. Create an observer file under app\/code\/Company\/Observer\/CustomObserver.php<\/p>\n\n\n\n
In the following observer, I am redirecting review routes to 404 when the review module is disabled.<\/p>\n\n\n\n
<?php\nnamespace Company\\Module\\Observer;\n\nuse Magento\\Framework\\Event\\ObserverInterface;\nuse Magento\\Framework\\Exception\\LocalizedException;\nuse Magento\\Framework\\Message\\ManagerInterface;\nuse Magento\\Store\\Model\\ScopeInterface;\n\nclass CustomObserver implements ObserverInterface\n{\n \/**\n * Configuration path to review active setting\n *\/\n const XML_PATH_REVIEW_ACTIVE = 'catalog\/review\/active';\n \/**\n * @var \\Magento\\Framework\\ObjectManagerInterface\n *\/\n protected $_objectManager;\n\n \/**\n * @var \\Magento\\Framework\\UrlInterface\n *\/\n protected $_urlInterface;\n \n \/**\n * [__construct ]\n *\n * @param \\Magento\\Framework\\ObjectManagerInterface $objectManager\n * @param \\Magento\\Framework\\UrlInterface $urlInterface\n *\/\n public function __construct(\n \\Magento\\Framework\\ObjectManagerInterface $objectManager,\n ScopeConfigInterface $scopeConfig,\n \\Magento\\Framework\\UrlInterface $urlInterface\n ) {\n $this->_objectManager = $objectManager;\n $this->scopeConfig = $scopeConfig;\n $this->_urlInterface = $urlInterface;\n }\n\n public function execute(\\Magento\\Framework\\Event\\Observer $observer)\n {\n \n if (!$this->scopeConfig->getValue(\n self::XML_PATH_REVIEW_ACTIVE,\n ScopeInterface::SCOPE_STORE\n )\n ) {\n $defaultNoRouteUrl = $this->scopeConfig->getValue(\n 'web\/default\/no_route',\n ScopeInterface::SCOPE_STORE\n );\n $redirectUrl = $this->_urlInterface->getUrl($defaultNoRouteUrl);\n $observer->getControllerAction()\n ->getResponse()\n ->setRedirect($redirectUrl);\n }\n }\n}<\/pre>\n","protected":false},"excerpt":{"rendered":"
