This is how the core achieves this: Javascript file: vendor/magento/module-checkout/view/frontend/web/js/view/payment.js:98getFormKey: function () { return window.checkoutConfig.formKey;}HTML file: vendor/magento/module-checkout/view/frontend/web/template/payment.html:19<form id="co-payment-form" class="form payments" novalidate="novalidate"> <input data-bind='attr: {value: getFormKey()}' type="hidden" name="form_key"/> ...</form>

Assuming you add a validation class via the frontend_class let's say "validate-custom-class" you'll need to use the following JS to add a custom validation based on a this class: require([ 'jquery', 'jquery/ui', 'jquery/validate', 'mage/translate'], function($){ $.validator.addMethod( 'validate-custom-class', function (value) { // Add your validation logic here // Needs to return true if validation pass // Or false if validation fails }, $.mage.__('Field is not valid'));});

You can use catalog_product_save_after, checkout_submit_all_after ,cataloginventory_stock_revert_products_sale, sales_order_item_cancel(Depending ) and get the stock status. You can even check for that product attribute value is as desired out of stock and that out of stock do nothing else update the attribute value .Put this events.xml in below path app\code\YOUR_NAMESPACE\YOURMODULE\etc\ <?xml version="1.0"?><config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd"> <event name="catalog_product_save_after"> <observer name="test_name" instance="YOUR_NAMESPACE\YOUR_MODULENAME\Observer\Productsaveafter" /> </event></config>And put your Productsaveafter.php in below path app\code\YOUR_NAMESPACE\YOURMODULE\Observer\ <?phpnamespace YOURNAMESPACE\YOURMODULENAME\Observer;use Magento\Framework\Event\ObserverInterface;class Productsaveafter implements ObserverInterface{ public function execute(\Magento\Framework\Event\Observer $observer) { $_product = $observer->getProduct(); // you will get product object and you can check for stock and attribute values here } }

Where are the products loaded?The products are loaded in the "_afterLoad" method of the items collection. A product collection is instantiated there based on the product ids of all items and directly loaded to assign the products to their wishlist items. Unfortunately it is instantiated and loaded from within the same method, so it is not easily changed via plugin. The attributes to select are hard coded: $attributesToSelect = [ 'name', 'visibility', 'small_image', 'thumbnail', 'links_purchased_separately', 'links_title', ];The method dispatches an event wishlist_item_collection_products_after_load, but unfortunately no "before load" event. ...

在本文中，咱们将理解问题的起因以及如何解决 Magento2 中“容许的内存耗尽谬误”的问题。 “allowed memory size of bytes exhausted”谬误的起因与内存不足无关。如果您尝试应用比您通过“memory_limit”在 php.ini 文件中指定的更多的 RAM 资源，则会产生谬误。 解决方案1： 在 php.ini 文件中，搜寻并更改以下值，如下所示 max_execution_time=18000 max_input_time=1800 memory_limit=4G并重新启动 Apache。解决方案2： Magento 2 命令中内存限度的疾速解决方案是间接在命令中增加内存限度。对于编译命令， php -dmemory_limit=4G bin/magento setup:di:compile用于部署 php -dmemory_limit=4G bin/magento setup:static-content:deploy如果问题没有解决，您能够依据 4G 更改为最大。 解决方案3： - 您能够应用此命令而不是 bin/magento 轻松修复它： php -dmemory_limit=-1 bin/magento ....例子： php -dmemory_limit=-1 bin/magento 设置：降级php -dmemory_limit=-1 bin/magento setup:di:compile此谬误与 PHP 中的内存限度配置无关。参数 -dmemory_limit=-1容许在没有内存限度的命令行中运行 PHP。 心愿这些解决方案能够帮忙您解决问题。

"|" . $this->cacheId;" with"$cacheId = implode('-', $this->scopePriorityScheme) . "-" . $this->cacheId;"
