How to call the shopping cart order quantity on the entire site of Dedecms5.7?

When I was selling the Dedecms5.7 GBK/UTF-8 Tenpay interface plug-in module, a netizen asked me about the number of orders in the shopping cart called by the Dedecms5.7 website. I checked the manual and couldn't find any relevant knowledge

After thinking about it, it's actually quite simple, just call the cookie data. Later I took a look at the Dedecms shopping cart class shopcar.class.php and found that there is a ready-made function cartCount available. In order not to affect the template call, I wrote a simple file myself and called it with javascript.

The method is implemented as follows:

1. Create a my_car_count.php file and place it under the /plus/ directory;

2. Write the following code:

The code is as follows:

<?php
/**
* my_car_count.php
* /plus
* 显示购物车的商品数量
* https://www.jb51.net/cms
* QQ: 834114969
*/
require_once (dirname(__FILE__) . "/../include/common.inc.php");
define(&#39;_PLUS_TPL_&#39;, DEDEROOT.&#39;/templets/plus&#39;);
require_once(DEDEINC.&#39;/dedetemplate.class.php&#39;);
require_once DEDEINC.&#39;/shopcar.class.php&#39;;
$cart = new MemberShops();</p> <p>$car_count = 0;</p> <p>if($cart->cartCount() >= 1)
{
$car_count = $cart->cartCount();
}
echo (&#39;document.write("&#39; . $car_count . &#39;"); &#39;);
exit;
?>

3. Write the calling code where you need to call it, for example: the number of items in the shopping cart
