限制在小推車小部件中顯示的產品的數量

Question

我正在使用WooCommerce小推車小部件，並且我想限制顯示在小推車中的產品的數量。如果用戶將10種產品添加到購物車中，則迷你購物車小部件會顯示全部10.

我想限制數量可以這麼說5個產品。

有沒有辦法做到這一點？

謝謝。

你可以通過你的活動主題，實現這一首要cart/mini-cart.php WooCommerce模板（見本相關的文檔：Template Structure + Overriding Templates via a Theme）。

簡單（如果尚未完成），您將需要從woocommerce插件文件夾複製，一個名爲templates到您的活動子主題（或主題）子文件夾，將其重命名woocommerce ..

之後，你會發現新的woocommerce文件夾內的cart子文件夾命名模板mini-cart.php。

打開/編輯mini-cart.php模板，並通過這種替換代碼，限制車5個項目：

<?php 
/** 
* Mini-cart 
* 
* Contains the markup for the mini-cart, used by the cart widget. 
* 
* This template can be overridden by copying it to yourtheme/woocommerce/cart/mini-cart.php. 
* 
* HOWEVER, on occasion WooCommerce will need to update template files and you 
* (the theme developer) will need to copy the new files to your theme to 
* maintain compatibility. We try to do this as little as possible, but it does 
* happen. When this occurs the version of the template file will be bumped and 
* the readme will list any important changes. 
* 
* @see  https://docs.woocommerce.com/document/template-structure/ 
* @author WooThemes 
* @package WooCommerce/Templates 
* @version 2.5.0

    <?php else : ?> 

     <li class="empty"><?php _e('No products in the cart.', 'woocommerce'); ?></li> 

    <?php endif; ?> 

</ul><!-- end product list --> 

<?php if (! WC()->cart->is_empty()) : ?> 

    <p class="total"><strong><?php _e('Subtotal', 'woocommerce'); ?>:</strong> <?php echo WC()->cart->get_cart_subtotal(); ?></p> 

    <?php do_action('woocommerce_widget_shopping_cart_before_buttons'); ?> 

    <p class="buttons"> 
     <a href="<?php echo esc_url(wc_get_cart_url()); ?>" class="button wc-forward"><?php _e('View Cart', 'woocommerce'); ?></a> 
     <a href="<?php echo esc_url(wc_get_checkout_url()); ?>" class="button checkout wc-forward"><?php _e('Checkout', 'woocommerce'); ?></a> 
    </p> 

<?php endif; ?> 

<?php do_action('woocommerce_after_mini_cart'); ?> 

在這裏，我們計算在foreach循環中的項目數，我們將其限制到指定號碼在變量$number_of_items。
