我需要在最近添加的产品上贴上"new"标签。我在 extension/module/latest.tpl 上完成了此操作，但我也希望此标签也能在其他页面上使用，例如 product/product.tpl， 产品/类别等等...

如何在不购买任何扩展程序的情况下执行此操作？

• OpenCart 2.3
• 模板:默认

更新

/controller/product/category.php

    /*start added part*/

                if(strtotime($result['date_added']) > (time() - (60*60*24*10) )){      
                    //(note that 10 means ten days, to consider a product as a new product, you can change it based on your need.)
                    $is_new = true;
                    } else {
                    $is_new = false;
                }
            /*end added part*/


            $data['products'][] = array(
                'is_new'      => $is_new,               //added code
                '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, $this->config->get($this->config->get('config_theme') . '_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)
            );
        }

这就是我在 product/category.tpl 中所做的

 <?php foreach ($products as $product) { ?>
    <div class="product-layout product-list col-xs-12">
      <div class="product-thumb">
        <div class="image"><a href="<?php echo $product['href']; ?>"><img src="<?php echo $product['thumb']; ?>" alt="<?php echo $product['name']; ?>" title="<?php echo $product['name']; ?>" class="img-responsive" /></a></div>
        <div>
          <div class="caption">
            <h4><a href="<?php echo $product['href']; ?>"><?php echo $product['name']; ?></a></h4>

            <?php if($product['is_new']){ ?><span>NEW</span><?php } ?>

            <p><?php echo $product['description']; ?></p>
            <?php if ($product['price']) { ?>

最佳答案

您可以比较产品的date_added在当前时间，您需要为类别修改两个文件: 第一个文件:catalog/controller/product/category.php

查找:

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

在它之前添加:

if(strtotime($result['date_added']) > (time() - (60*60*24*10) )){
    $is_new = true;
} else {
    $is_new = false;
}

(注意10表示十天，将产品视为新产品，您可以根据需要更改。)

在其后添加:

'is_new'      => $is_new,

现在这个部分必须是这样的:

if(strtotime($result['date_added']) > (time() - (60*60*24*10) )){
    $is_new = true;
} else {
    $is_new = false;
}

$data['products'][] = array(
    'is_new'      => $is_new,
    '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, $this->config->get($this->config->get('config_theme') . '_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),
);

第二个文件:catalog/view/theme/default/template/product/category.tpl

在 foreach 中添加此代码产品循环，例如之前:<p><?php echo $product['description']; ?></p> :

<?php if($product['is_new']){ ?><span class="new-product">NEW</span><?php } ?>

我为 vqmod 创建了一个 xml 脚本:

<?xml version="1.0" encoding="UTF-8"?>
<modification>
    <id>Products New Label</id>
    <version>2.x</version>
    <vqmver required="true">2.6.0</vqmver>
    <author>sabeti05@gmail.com</author>

    <file name="catalog/controller/product/category.php">
        <operation error="skip">
            <search position="replace"><![CDATA[$data['products'][] = array(]]></search>
            <add><![CDATA[
                if(strtotime($result['date_added']) > (time() - (60*60*24*10) )){
                    $is_new = true;
                } else {
                    $is_new = false;
                }
                $data['products'][] = array(
                    'is_new'      => $is_new,
            ]]></add>
        </operation>
    </file>

    <file name="catalog/view/theme/*/template/product/category.tpl">
        <operation error="skip">
            <search position="before"><![CDATA[<p><?php echo $product['description']; ?></p>]]></search>
            <add><![CDATA[
                <?php if($product['is_new']){ ?><span class="new-product">NEW</span><?php } ?>
            ]]></add>
        </operation>
