Question

我需要在Module Featured产品

上显示此自定义字段

Check image here

目前它只在产品页面上显示此字段，需要在模块特色产品中显示此字段

我已将此代码放入Controller中目录/控制器/扩展/模块/ featured.php $ data [＆＃39; extra_field＆＃39;] = html_entity_decode（$ product_info [＆＃39; extra_field＆＃39;]，ENT_QUOTES，＆＃39; UTF-8＆＃39;）;

但没有工作...... 有人能帮助我吗？

这是自定义字段

您还需要让您的代码在特色产品中运行;它使用与product.php不同的代码库：

控制器： /your_dir/catalog/controller/extension/module/featured.php：

周边：

'name'        => $product_info['name'],
'extra_field' => $product_info['extra_field'],

查看： /your_dir/catalog/view/theme/your_theme/template/extension/module/featured.tpl：将其添加到您希望显示的位置，例如：

<?php if ($product['extra_field']) { ?>
     //your extra field stuff goes here
<?php } ?>

在模块特色产品opencart上显示自定义字段
