Php 在Opencart 2的产品页面中显示重量单位

嗨

如何在Opencart 2.0.2.0的产品页面中显示重量单位（千克、克、盎司、毫升）

现在只显示一个没有单位的数字

我使用的是默认模板

在文件template\product\product.tpl中，如下所示：

...<li><?php echo $text_model; ?> <?php echo $model; ?></li>

<?php if ($weight) { ?>

<li><?php echo $text_weight; ?>
<?php
echo round($weight, 2)?></li>
 <?php } ?> ...

---

还需要添加或更改哪些内容？

在默认OpenCart代码中尝试类似的内容

第一步 打开文件

catalog/controller/product/product.php

查找（第242行附近）：

在以下内容之后添加：

$data['text_weight'] = $this->language->get('text_weight');

$data['weight'] = $product_info['weight'];
$tablewunit = $this->db->query("SELECT wcd.unit FROM " . DB_PREFIX . "weight_class_description wcd WHERE (wcd.weight_class_id = " . $product_info['weight_class_id'] . ") AND wcd.language_id = '" . (int)$this->config->get('config_language_id') . "'");
$data['weightunit'] = $tablewunit->row['unit'];

$_['text_weight']       = 'Weight:';

<li><?php echo $text_weight; ?> <?php echo $weight . ' ' . $weightunit; ?></li>

步骤2 在同一个文件

catalog/controller/product/product.php

查找（第270行附近）：

在以下内容之后添加：

$data['text_weight'] = $this->language->get('text_weight');

$data['weight'] = $product_info['weight'];
$tablewunit = $this->db->query("SELECT wcd.unit FROM " . DB_PREFIX . "weight_class_description wcd WHERE (wcd.weight_class_id = " . $product_info['weight_class_id'] . ") AND wcd.language_id = '" . (int)$this->config->get('config_language_id') . "'");
$data['weightunit'] = $tablewunit->row['unit'];

$_['text_weight']       = 'Weight:';

<li><?php echo $text_weight; ?> <?php echo $weight . ' ' . $weightunit; ?></li>

步骤3 打开文件

catalog/language/english/product/product.php

查找（第6行附近）：

在以下内容之后添加：

$data['text_weight'] = $this->language->get('text_weight');

$data['weight'] = $product_info['weight'];
$tablewunit = $this->db->query("SELECT wcd.unit FROM " . DB_PREFIX . "weight_class_description wcd WHERE (wcd.weight_class_id = " . $product_info['weight_class_id'] . ") AND wcd.language_id = '" . (int)$this->config->get('config_language_id') . "'");
$data['weightunit'] = $tablewunit->row['unit'];

$_['text_weight']       = 'Weight:';

<li><?php echo $text_weight; ?> <?php echo $weight . ' ' . $weightunit; ?></li>

步骤4 打开文件

catalog/view/theme/default（您的主题）/template/product/product.tpl

查找（第141行附近）：

在以下内容之后添加：

$data['text_weight'] = $this->language->get('text_weight');

$data['weight'] = $product_info['weight'];
$tablewunit = $this->db->query("SELECT wcd.unit FROM " . DB_PREFIX . "weight_class_description wcd WHERE (wcd.weight_class_id = " . $product_info['weight_class_id'] . ") AND wcd.language_id = '" . (int)$this->config->get('config_language_id') . "'");
$data['weightunit'] = $tablewunit->row['unit'];

$_['text_weight']       = 'Weight:';

<li><?php echo $text_weight; ?> <?php echo $weight . ' ' . $weightunit; ?></li>

非常感谢！它起作用了！我承诺开始学习php和Opencart！还针对oc3.0.2进行了修改，效果非常好！谢谢）非常感谢！它起作用了！我承诺开始学习php和Opencart！还针对oc3.0.2进行了修改，效果非常好！（谢谢）
