如何在product.tpl中爲製造商描述寫入true ocmod？

Question

我的問題：這是我的第一個Open Cart項目，我不知道這個MVCL好）所以我需要爲OpenCart 2.3.0.2編寫ocmod修改，以便在產品頁面中添加製造商描述。年初，我發現ocmod爲附加製造商說明製造商網頁和編輯這個模塊對於我這個代碼：

<?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});

     </operation> 
     </file> 
     <!-- tab in product.tpl page --> 
     <!-- code voew --> 
    </modification> 

並在數據庫中添加列：

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

如果我做錯了？這返回此錯誤：

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 

但我不知道什麼寫在控制器我認爲。請幫助！））

解決此問題！我錯誤的使用地方添加代碼在控制器product.php現在看起來是正確的：

<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>
