php - 如何在 product.tpl 中为制造商描述写入 true ocmod？

Question

我的问题:这是我的第一个 Open Cart 项目，我不知道这个 MVCL 好))所以我需要为 OpenCart 2.3.0.2 编写 ocmod 修改，以便在产品页面中添加制造商描述。早期我找到 ocmod 用于将制造商描述添加到制造商页面并为我编辑此模块此代码:

<?xml version="1.0" encoding="utf-8"?>
    <modification>
        <name>Manufacturer description</name>
        <code>default</code>
        <version>1.0</version>
        <author></author>
        <link></link>
        <!-- code admin panel -->
        <file path="admin/view/template/catalog/manufacturer_form.tpl">
        <operation>
            <search index="0"><![CDATA[<div class="form-group">]]></search>
            <add position="before"><![CDATA[
              <div class="form-group required">
                <label class="col-sm-2 control-label" for="input-description">Описание</label>
                <div class="col-sm-10">
                  <textarea name="descriptionmanufacturer" rows="5" placeholder="Описание" id="input-description" class="form-control"><?php echo isset($descriptionmanufacturer) ? $descriptionmanufacturer : ''; ?></textarea>
                 </div>
              </div>

            <script type="text/javascript">
                $('#input-description').summernote({height: 100});
            </script>

        <!-- code voew -->
    </modification>

并在数据库中添加列:

ALTER TABLE `oc_manufacturer` ADD `descriptionm` TEXT NOT NULL AFTER `sort_order`;

我哪里做错了？？这将返回此错误:

Notice: Undefined variable: manufacturer_info in C:\OpenServer\domains\apostle.loc\system\storage\modification\catalog\controller\product\product.php on line 72
Notice: Undefined variable: manufacturer_info in C:\OpenServer\domains\apostle.loc\system\storage\modification\catalog\controller\product\product.php on line 74

但我不知道我认为在 Controller 中写了什么。请帮忙!))

这个问题解决了!我在 Controller product.php 中错误地使用了添加代码的地方，现在它看起来是正确的:

<file path="catalog/controller/product/product.php">
<operation>
    <search><![CDATA[$data['heading_title'] = $product_info['name'];]]></search>
    <add position="after"><![CDATA[
        $manufacturer_info = $this->model_catalog_manufacturer->getManufacturer($product_info['manufacturer_id']);
        $data['descriptionmanufacturer'] = html_entity_decode($manufacturer_info['descriptionm'], ENT_QUOTES, 'UTF-8');
        ]]></add>
</operation>
</file>
