I aim to display it over my " go to cart " link that is an image with an href. But this is not the main pb. The main pb is how to find a way to get only the number of item in the cart.
我的目标是将它显示在我的“转到购物车”链接上，该链接是带有 href 的图像。但这不是主要的pb。主要的 pb 是如何找到一种方法来仅获取购物车中的商品数量。
I'm using WordPress with Avada installed to be able to customize a bit more WP and get some includes features. But i'm not using the avada menu, I'm using a home made menu, and i want to display in it the number of item in cart.

Hey and welcome to the site, though I am new around here too! The WooCommerce documentation actually has a snippet for exactly this purpose:
嘿，欢迎来到该网站，尽管我也是新来的！WooCommerce 文档实际上有一个专门用于此目的的片段：
https://docs.woocommerce.com/document/show-cart-contents-total/
https://docs.woocommerce.com/document/show-cart-contents-total/
In your case to just get the count, you could do something like this:
在你的情况下只是得到计数，你可以做这样的事情：
Cart Total: <?php echo WC()->cart->get_cart_contents_count(); ?>

From your given description I understand that you want to show cart count only and nothing else. Here goes the code to do that
从您给出的描述中，我了解到您只想显示购物车数量而不显示其他内容。这是执行此操作的代码
Add This code block In header.php or in that file where you want to display this widget...
在 header.php 或要显示此小部件的文件中添加此代码块...
<a class="cart-customlocation" href="<?php echo wc_get_cart_url(); ?>" title="<?php _e( 'View your shopping cart' ); ?>"><?php WC()->cart->get_cart_contents_count(); ?></a>
And Then Add this code block to functions.php
然后将此代码块添加到functions.php
add_filter('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-customlocation" href="<?php echo wc_get_cart_url(); ?>" title="<?php _e( 'View your shopping cart' ); ?>"><?php WC()->cart->get_cart_contents_count(); ?></a>
<?php
$fragments['a.cart-customlocation'] = ob_get_clean();
return $fragments;
}

From here:
从这里：
Add this code in your header.php file.
将此代码添加到 header.php 文件中。
<a class="cart-contents" href="<?php echo wc_get_cart_url(); ?>" title="<?php _e( 'View your shopping cart' ); ?>"><?php echo sprintf ( _n( '%d item', '%d items', WC()->cart->get_cart_contents_count() ), WC()->cart->get_cart_contents_count() ); ?> - <?php echo WC()->cart->get_cart_total(); ?></a>

Further to Kodaloid's answer, you can also only show the cart count if it is greater than 0.
除了 Kodaloid 的回答之外，您还可以仅显示大于 0 的购物车计数。
<?php
$cartcount = WC()->cart->get_cart_contents_count();
if ($cartcount > 0) { echo $cartcount; }
?>回答by ale
get_cart_contents_count() show the total quantity of all product items. i.e. you buy 2kg of product A and 1kg of product B, get_cart_contents_count() return 3.
get_cart_contents_count() 显示所有产品的总数量。即您购买 2 公斤产品 A 和 1 公斤产品 B，get_cart_contents_count() 返回 3。
If you need to show how many products are in cart, I did this function, in functions.php:
如果你需要显示购物车中有多少产品，我在functions.php中做了这个功能：
function count_item_in_cart() {
$count = 0;
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
$count++;
}
return $count;
}
then in your php file you can do that:
然后在你的 php 文件中你可以这样做：
<?php echo count_item_in_cart() . " products"; ?>
