我试图在 mod_virtuemart_product 模块中安装我的模块以进行实时搜索。我以这种方式更改了 mod_virtuemart_product.xml：
旧代码

我以这种方式在 mod_virtuemart_product/tmpl 文件夹中创建了新的 php 文件和 javascript 文件：
我以这种方式在 mod_virtuemart_product/tmpl 文件夹中创建了新的 php 文件和 javascript 文件：
mod_virtuemart_product/tmpl/quicksearch.php
mod_virtuemart_product/tmpl/default.php - used by virtuemart (I just add to this code
my search input code)
mod_virtuemart_product/tmpl/head.php
mod_virtuemart_product/tmpl/config.php
mod_virtuemart_product/tmpl/js/javascript.js
mod_virtuemart_product/tmpl/css/css.css
一切都是相连的。我的代码可以正常工作，但是当我想将此代码添加到我的 quicksearch.php 文件时： echo mod_virtuemart_product::addtocart ($product);
它给我写了这个错误：
“致命错误：在第 34 行的 /www/t/r/u46223/public_html/modules/mod_virtuemart_product/tmpl/quicksearch.php 中找不到类 'mod_virtuemart_product'”
你能告诉我，有什么问题吗？
谢谢你。
这是 mod_virtuemart_product.php 文件。我想将此函数“mod_virtuemart_product::addtocart ($product)”添加到我的文件 quicksearch.php 中，该文件位于 modules/mod_virtuemart_product/tmpl 文件夹中。谢谢。
