Question

我在产品列表中添加了qty输入（list.phtml）是否可以通过购物车页面或minicart实现更新数量的解决方案？不只是添加到购物车，而是更新产品列表中的数量。

Answer 1

您可以使用以下内容：

<?php $postParams = $block->getAddToCartPostParams($_product); ?>

<form data-role="tocart-form" onsubmit="return false;" action="<?php /* @escapeNotVerified */ echo $postParams['action']; ?>" method="post">
    <?php echo $block->getBlockHtml('formkey')?>
    <input type="hidden" name="product" value="<?php /* @escapeNotVerified */ echo $postParams['data']['product']; ?>">
    <input type="hidden" name="<?php /* @escapeNotVerified */ echo Action::PARAM_NAME_URL_ENCODED; ?>" value="<?php /* @escapeNotVerified */ echo $postParams['data'][Action::PARAM_NAME_URL_ENCODED]; ?>">
    <input type="text" name="qty" id="qty" class="qty" value="1"/>
    <button type="submit"
            title="<?php echo $block->escapeHtml(__('Add to Cart')); ?>"
            class="action tocart primary"
            <span class="label">
                <?php /* @escapeNotVerified */ echo __('Add to Cart') ?>
            </span>
    </button>                                                
</form>

但这只适用于简单的产品。

将mincart.phtml中的以下代码替换为deply：

// @codingStandardsIgnoreFile

/** @var $block \Magento\Checkout\Block\Cart\Sidebar */
?>

<div data-block="minicart" class="minicart-wrapper">
    <a class="action showcart" href="<?php /* @escapeNotVerified */ echo $block->getShoppingCartUrl(); ?>"
       data-bind="scope: 'minicart_content'">
        <span class="text"><?php /* @escapeNotVerified */ echo __('Warenkorb'); ?></span>
        <span class="counter qty empty"
              data-bind="css: { empty: !!getCartParam('summary_count') == false }, blockLoader: isLoading">
