我正在一个基于woocommerce的网站上工作。我使用了找到的建议代码段here 将购物车内容链接添加到我的标题。代码如下：

在您的功能中。php

<?php

// Ensure cart contents update when products are added to the cart via AJAX (place the following in functions.php)
add_filter( \'woocommerce_add_to_cart_fragments\', \'woocommerce_header_add_to_cart_fragment\' );

function woocommerce_header_add_to_cart_fragment( $fragments ) {
    ob_start();
    ?>
    <a class="cart-contents" href="<?php echo WC()->cart->get_cart_url(); ?>" title="<?php _e( \'View your shopping cart\' ); ?>"><?php echo sprintf (_n( \'%d item\', \'%d items\', WC()->cart->cart_contents_count ), WC()->cart->cart_contents_count ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a> 
    <?php

    $fragments[\'a.cart-contents\'] = ob_get_clean();

    return $fragments;
}

代码是ajaxified的，以便自动将产品的编号和价格添加到链接中。

在主题文件中

<a class="cart-contents" href="<?php echo WC()->cart->get_cart_url(); ?>" title="<?php _e( \'View your shopping cart\' ); ?>"><?php echo sprintf (_n( \'%d item\', \'%d items\', WC()->cart->cart_contents_count ), WC()->cart->cart_contents_count ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a>

我面临的问题是，我想在链接中添加一个额外的类，如下所示：

 <a class="cart-contents fi-shopping-cart" href="<?php echo WC()->cart->get_cart_url(); ?>" title="<?php _e( \'View your shopping cart\' ); ?>"><?php echo sprintf (_n( \'%d item\', \'%d items\', WC()->cart->cart_contents_count ), WC()->cart->cart_contents_count ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a>

此附加类用于zurb found创建的字体图标here. 显示字体图标所需的只是将其作为类添加到div或li中。问题是，每当我刷新页面时，字体图标会在瞬间显示，然后消失。我真的很感激你的帮助。非常感谢。

<?php

// Ensure cart contents update when products are added to the cart via AJAX (place the following in functions.php)
add_filter( \'woocommerce_add_to_cart_fragments\', \'woocommerce_header_add_to_cart_fragment\' );

function woocommerce_header_add_to_cart_fragment( $fragments ) {
    ob_start();
    ?>
    <a class="cart-contents fi-shopping-cart" href="<?php echo WC()->cart->get_cart_url(); ?>" title="<?php _e( \'View your shopping cart\' ); ?>"><?php echo sprintf (_n( \'%d item\', \'%d items\', WC()->cart->cart_contents_count ), WC()->cart->cart_contents_count ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a> 
    <?php

    $fragments[\'a.cart-contents\'] = ob_get_clean();

    return $fragments;
}

<a class="cart-contents fi-shopping-cart" href="<?php echo WC()->cart->get_cart_url(); ?>" title="<?php _e( \'View your shopping cart\' ); ?>"><?php echo sprintf (_n( \'%d item\', \'%d items\', WC()->cart->cart_contents_count ), WC()->cart->cart_contents_count ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a>
