目录/查看/主题/默认/common/header.tpl
我做了echo $ them_default_product_description_length
您需要编辑主题文件：catalogviewthemethemenametemplatecommonheader.tpl及其控制器文件catalogcontrollercommonheader.php才能显示数据。要获取数据，您可以查看处理屏幕截图中页面的控制器文件：
admincontrollerextensionthemetheme_default.php
编辑
测试后，一种更容易的方法是一行（您可以删除我给您的其他代码 - 对不起）
$data['theme_default_product_description_length'] = $this->config->get('theme_default_product_description_length');
您现在应该能够在header.tpl文件上使用echo $theme_default_product_description_length;
尝试找到使用的位置，查看数据的存储/检索方式，然后将代码应用于所需的修改
