I recently came across a situation where I needed to be able to turn off payment method on checkout based on customer information on a Magneto 2 site.<\/p>\n
The best solution seemed to be to tie into the payment_method_is_active event. I left the payment method turned on in the admin for ease of use and clarity to the store owner and had my observer turn off the method based on criteria.<\/p>\n
The code structure you need is pretty simple
\napp\/code\/Evermore\/Payment is the root of my extension.<\/p>\n
As with all extension, add the registration.php file<\/p>\n
registration.php<\/p>\n
<?php\r\n\r\n\\Magento\\Framework\\Component\\ComponentRegistrar::register(\r\n\\Magento\\Framework\\Component\\ComponentRegistrar::MODULE,\r\n'Evermore_Payment',\r\n__DIR__\r\n);<\/pre>\nThen add the module.xml file.<\/p>\n
etc\/module.xml<\/p>\n
<?xml version=\"1.0\"?>\r\n \r\n<config xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\" xsi:noNamespaceSchemaLocation=\"urn:magento:framework:Module\/etc\/module.xsd\">\r\n <module name=\"Evermore_Payment\" setup_version=\"0.0.1\">\r\n <\/module>\r\n<\/config><\/pre>\nNow an events.xml file to add the observer call.<\/p>\n
etc\/events.xml<\/p>\n
<?xml version=\"1.0\"?>\r\n<config xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\" xsi:noNamespaceSchemaLocation=\"urn:magento:framework:Event\/etc\/events.xsd\">\r\n <event name=\"payment_method_is_active\">\r\n <observer name=\"Evermore_Payment_Method_Is_Active\" instance=\"Evermore\\Payment\\Observer\\DisablePaymentMethods\" \/>\r\n <\/event>\r\n<\/config>\r\n<\/pre>\nNow the structure is in place to call your Observer.\u00a0 Finally add the Observer file.<\/p>\n
Observer\/DisablePaymentMethods.php<\/p>\n
<?php\r\n\r\n\/**\r\n * Disables Payment Method of PO if the customer doesn't have approved billing terms.\r\n *\r\n *\/\r\n\r\nnamespace Evermore\\Payment\\Observer;\r\n\r\nuse Magento\\Framework\\Event\\Observer;\r\nuse Magento\\Framework\\Event\\ObserverInterface;\r\nuse Psr\\Log\\LoggerInterface;\r\n\r\nclass DisablePaymentMethods implements ObserverInterface {\r\n protected $_customerInterface;\r\n protected $_logger;\r\n\r\n public function __construct(\r\n \\Magento\\Customer\\Api\\CustomerRepositoryInterface $customerInterface,\r\n LoggerInterface $logger\r\n ) {\r\n $this->_customerInterface = $customerInterface;\r\n $this->_logger = $logger;\r\n }\r\n\r\n \/**\r\n * @param Observer $observer\r\n *\r\n * @return void\r\n *\/\r\n public function execute(Observer $observer) {\r\n \/\/Replace this code with your own checks.

php bin\/magento setup:upgrade\r\nphp bin\/magento setup:di:compile\r\n<\/pre>\nAnd you’re done.<\/p>\n
