Get a tag assigned to custom post type

Question

I'm using WooCommerce and have tagged one of products (custom post type is product) with the tag "electronic".

I'm now trying to loop through and obtain the tag assigned to that post, but currently, when trying to dump the data, I'm returned with bool(false).

Here is my approach:

<?php
$args = array(
    'post_type' => 'product',
    'p' => $product_name,
    'posts_per_page' => 1
);

$loop = new WP_Query($args);

while ($loop->have_posts()):
    $loop->the_post();

    $posttags = get_the_tags();
    if ($posttags)
    {
        foreach ($posttags as $tag)
        {
            echo $tag->name;
        }
    }

    var_dump($posttags);

endwhile;
wp_reset_query();

?>
<?php
$args = array(
    'post_type' => 'product',
    'p' => $product_name,
    'posts_per_page' => 1
);

$loop = new WP_Query($args);

while ($loop->have_posts()):
    $loop->the_post();

    $posttags = get_the_tags();
    if ($posttags)
    {
        foreach ($posttags as $tag)
        {
            echo $tag->name;
        }
    }

    var_dump($posttags);

endwhile;
wp_reset_query();

?>

Have tried:

<?php
global $post;

$args = array(
    'post_type' => 'product',
    'p' => $product_name,
    'posts_per_page' => 1
);

$loop = new WP_Query($args);

$product_tags = get_the_terms($post, 'product_tag');

while ($loop->have_posts()):
    $loop->the_post();

    if ($product_tags){
        foreach ($product_tags as $tag){
            echo $tag->name;
        }
    }

endwhile;
wp_reset_query(); ?>

But the above doesn't echo anything?

I believe get_the_tags() is used only for post tags, not WooCommerce's product tags. For WooCommerce, the taxonomy should be product_tag. You may use

<?php
$product_tags = get_the_terms( $post, 'product_tag' );
?>

to get the tags and then loop over them as required.

Full code example:

<?php
global $post;

$args = array(
    'post_type' => 'product',
    'p' => $product_name,
    'posts_per_page' => 1
);

$loop = new WP_Query($args);

while ($loop->have_posts()):
    $loop->the_post();

    $product_tags = get_the_terms($post, 'product_tag');

    if ($product_tags && !is_wp_error($product_tags){
        foreach ($product_tags as $tag){
            echo $tag->name;
        }
    }

endwhile;
wp_reset_query(); ?>
