从 catalog/template - opencart 访问 admin/controller 中的变量

Access variables in admin/controller, from catalog/template - opencart

是否可以从目录模板访问保存在管理设置中的变量。
admin/controller/extension/theme/themename.phpcatalog/view/theme/themename/template/common/header.tpl.
假设我想从 header.tpl 访问 List Description Limit - image link - 中的值 themename.php,例如 <?php echo List Description Limit; ?>?

控制器文件:

}

catalog/view/theme/default/common/header.tpl
我确实 echo $theme_default_product_description_length

您需要编辑主题文件:catalog\view\theme\themename\template\common\header.tpl 及其控制器文件 catalog\controller\common\header.php 以显示数据。要获取数据,您可以查看屏幕截图中处理页面的控制器文件:

\admin\controller\extension\theme\theme_default.php

编辑

经过测试,更简单的方法是单行(您可以删除我给您的其他代码 - 抱歉)

$data['theme_default_product_description_length'] = $this->config->get('theme_default_product_description_length');

您现在应该可以在 header.tpl 文件上使用 echo $theme_default_product_description_length;

尝试找到使用它的地方,查看数据的存储/检索方式,然后将代码应用于您想要的修改总是有用的
