category.tpl中的Opencart 2.0屬性頁面

Question

我想在category.tpl頁面的產品中添加屬性。 我只爲以前的opencart版本找到答案。但在這一個它不工作：

- 在/catalog/model/catalog/product.php 更換內容

"public function getProductAttributes($product_id) {", 

public function getProductAttributesnocat($product_id) { 
 
$product_attribute_data = array(); 
 
$product_attribute_query = $this->db->query("SELECT a.attribute_id, ad.name, pa.text FROM " . DB_PREFIX . "product_attribute pa LEFT JOIN " . DB_PREFIX . "attribute a ON (pa.attribute_id = a.attribute_id) LEFT JOIN " . DB_PREFIX . "attribute_description ad ON (a.attribute_id = ad.attribute_id) WHERE pa.product_id = '" . (int)$product_id . "' AND ad.language_id = '" . (int)$this->config->get('config_language_id') . "' AND pa.language_id = '" . (int)$this->config->get('config_language_id') . "' ORDER BY a.sort_order, ad.name"); 
 
foreach ($product_attribute_query->rows as $product_attribute) { 
 
    $product_attribute_data[] = array(
 
     'attribute_id' => $product_attribute['attribute_id'], 
 
     'name' => $product_attribute['name'], 
 
     'text' => $product_attribute['text'] 
 
     ); 
 
    } 
 
return $product_attribute_data; 
 
}

- in /catalog/controller/product/category.php after

$data['products'][] = array(

添加

'attribute' => $this->model_catalog_product->getProductAttributes($result['product_id']), 

- 在/catalog/view/my_theme/default/template/product/category.tpl 前

<?php if ($product['rating']) { ?> 

添加

<?php if ($product['attribute']) { ?> 
 
    <?php foreach ($product['attribute'] as $attribute) { ?> 
 
     <span><?php echo $attribute['name']; ?>:</span> <?php echo $attribute['text']; ?><br /> 
 
    <?php } ?> 
 
<?php } ?>

作爲結果Opencart的說：

注意：未定義指數：屬性在... /目錄/視圖/主題/ my_theme /模板/產品/上線category.tpl 127

但我不強大的PHP。將非常感謝，如果你能幫助。

雖然我建議使用VqMod，但手動可以執行以下操作： 公開目錄/控制器/產品/ category.php，找到下面的代碼：

$data['products'][] = array(
       'product_id' => $result['product_id'], 
       'thumb'  => $image, 
       'name'  => $result['name'], 
       'description' => utf8_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, $this->config->get('config_product_description_length')) . '..', 
       'price'  => $price, 
       'special'  => $special, 
       'tax'   => $tax, 
       'minimum'  => $result['minimum'] > 0 ? $result['minimum'] : 1, 
       'rating'  => $result['rating'], 
       'href'  => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id'] . $url) 
      ); 

現在添加一行在它「attribute_groups '=> $這 - > model_catalog_product-> getProductAttributes（$結果[' PRODUCT_ID']），然後產品陣列將是象下面這樣：

$data['products'][] = array(
       'product_id' => $result['product_id'], 
       'thumb'  => $image, 
       'attribute_groups'  => $this->model_catalog_product->getProductAttributes($result['product_id']), 
       'name'  => $result['name'], 
       'description' => utf8_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, $this->config->get('config_product_description_length')) . '..', 
       'price'  => $price, 
       'special'  => $special, 
       'tax'   => $tax, 
       'minimum'  => $result['minimum'] > 0 ? $result['minimum'] : 1, 
       'rating'  => $result['rating'], 
       'href'  => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id'] . $url) 
      ); 

現在公開目錄/視圖/主題/ YOUR_THEME_FOLDER /模板/產品/ category.tpl並添加如下代碼略低於<p><?php echo $product['description']; ?></p>

<p> 
       <?php if ($product['attribute_groups']) { ?> 
      <div class="tab-pane" id="tab-specification"> 
       <table class="table table-bordered"> 
       <?php foreach ($product['attribute_groups'] as $attribute_group) { ?> 
       <thead> 
       <tr> 
        <td colspan="2"><strong><?php echo $attribute_group['name']; ?></strong></td> 
       </tr> 
       </thead> 
       <tbody> 
       <?php foreach ($attribute_group['attribute'] as $attribute) { ?> 
       <tr> 
        <td><?php echo $attribute['name']; ?></td> 
        <td><?php echo $attribute['text']; ?></td> 
       </tr> 
       <?php } ?> 
       </tbody> 
       <?php } ?> 
       </table> 
      </div> 
      <?php } ?> 
      </p>
