Add label to recently added products in OpenCart

Question

I need to have a label "new" on products which were added recently. I have this done on extension/module/latest.tpl, but I'd like also to have this label working on another pages too, like product/product.tpl, product/category and so on...

How can I do this without buying any extensions?

• OpenCart 2.3
• Template: default

UPDATE

/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)
            );
        }

And this is what i did in product/category.tpl

 <?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']) { ?>

You can compare product's date_added with current time, you need to modify two file for category : Fisrt file: catalog/controller/product/category.php

find:

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

add before it:

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

(note that 10 means ten days, to consider a product as a new product, you can change it based on your need.)

add after it:

'is_new'      => $is_new,

Now this section must be like this:

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),
);

Second file: catalog/view/theme/default/template/product/category.tpl

add this code inside foreach loop of products, for example before: <p><?php echo $product['description']; ?></p> :

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

I created a xml script for vqmod:
