我想知道是否有人能帮我做点什么？

我在网上找到此代码：

// Add a WooCommerce Cart Total shortcode [cart_total]
add_filter(\'woocommerce_add_to_cart_fragments\', \'woocommerce_header_add_to_cart_fragment\');
function woocommerce_header_add_to_cart_fragment( $fragments ) {
global $woocommerce;
ob_start();
?>

<a class="cart-contents" href="<?php echo $woocommerce->cart->get_cart_url(); ?>" title="<?php _e(\'View your shopping cart\', \'woothemes\'); ?>"><i class="fa fa-shopping-cart "></i>&nbsp;<?php echo $woocommerce->cart->cart_contents_count;?></a>

<?php
$fragments[\'a.cart-contents\'] = ob_get_clean();
return $fragments;
}

add_shortcode( \'cart_total\',\'cart_total_function\' );
function cart_total_function( $cart_total ){
global $woocommerce;
$cart_total = \'<a class="cart-contents" href="#"><i class="fa fa-shopping-cart "></i>&nbsp;\'.$woocommerce->cart->cart_contents_count.\'</a>\';
/* Original code */
// $cart_total = \'<a class="cart-contents" href="\'.$woocommerce->cart->get_cart_url().\'" title="View your shopping cart">\'.sprintf(_n(\'%d item\', \'%d item(s) \', $woocommerce->cart->cart_contents_count, \'woothemes\'), $woocommerce->cart->cart_contents_count).\'&nbsp;\'.$woocommerce->cart->get_cart_total().\'</a>\';
return $cart_total;
}

这允许我在我的网站上的任何地方使用[cart\\u total]快捷码。它工作得很好，但我想做的是，当购物车为空时，不要吐出任何东西，因此基本上只有当有人向购物车中添加了一些东西时，输出才会显示出来。这纯粹是出于美学原因。

我很确定我需要利用if 语句来检查cart\\u contents\\u计数，但无法确定将if语句放置在何处。我已经尝试了大约12种不同的方法，但都没有成功。几乎所有人都在抛出错误。实际上，我只知道足够危险的代码，所以不知道我在做什么是对的还是错的。只有当它起作用时，我才知道我“得到”了它！！；-）

在此方面的任何帮助都将不胜感激。

非常感谢。

致以最良好的祝愿，
