如果我关闭woocommerce插件，则会收到页面错误，无法修复，它与商店购物车标题有关

对于我的头文件, 我在下面有以下代码。但是, 如果我关闭Woocommerce插件, 则会收到很多错误代码(请参见下文)

< ul class="site-header-cart menu"> < li> < ?php storefront_cart_link(); ?> < /li> < li> < ?php the_widget( 'WC_Widget_Cart', 'title=' ); ?> < /li> < /ul>

/////////////////
这与这一行有关-这是否需要成为if语句。我已经尝试修复了几个小时, 但没有成功。我只是对PHP有基本了解的新手
【如果我关闭woocommerce插件，则会收到页面错误，无法修复，它与商店购物车标题有关】当打开” woocommerce” 时, 页面看起来没有错误, 但是控制台镶边中明显出现了一些jquery错误-因此尝试修复错误代码

#1假设此模板是自定义的, 并且此行为是由于该模板希望始终安装WooCommerce而引起的, 则只需在发布的header.php文件中删除对未定义函数的引用即可：

< div class="col-xs-12 col-sm-12 col-md-2 col-lg-2"> < ul class="site-header-cart menu"> < li> < ?php //storefront_cart_link(); ?> < /li> < li> < ?php the_widget( 'WC_Widget_Cart', 'title=' ); ?> < /li> < /ul> < /div>

在上面, 我已注释掉storefront_cart_link(); 。函数调用。我不知道删除函数调用的含义。尝试过此方法后最好对其进行测试, 看看是否有帮助！
