How to get featured image of a product in woocommerce

Please tell me where I am going wrong . Product featured image is not showing up.

   $args = array( 'post_type' => 'product', 'posts_per_page' => 80, 'product_cat' => 'profiler', 'orderby' => 'rand' );

	$loop = new WP_Query( $args );

   while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>

    <div class="dvThumb col-xs-4 col-sm-3 col-md-3 profiler-select profiler<?php echo the_title(); ?>" data-profile="<?php echo $loop->post->ID; ?>">

    <img src="<?php  get_the_post_thumbnail($loop->post->ID); ?>" data-id="<?php echo $loop->post->ID; ?>">

    <p><?php the_title(); ?></p>
										
    <span class="price"><?php echo $product->get_price_html(); ?></span>                    
    </div>

I have already added a featured image in back end

I got the solution . I tried this .

<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $product_id ), 'single-post-thumbnail' );?>
										
	<img src="<?php  echo $image[0]; ?>" data-id="<?php echo $loop->post->ID; ?>">

The answers here, are way too complex. Here's something I've recently used:

<?php global $product; ?>
<img src="<?php echo wp_get_attachment_url( $product->get_image_id() ); ?>" />

Using wp_get_attachment_url() to display the

I would just use get_the_post_thumbnail_url() instead of get_the_post_thumbnail()

<img src="<?php echo get_the_post_thumbnail_url($loop->post->ID); ?>" class="img-responsive" alt=""/>

In WC 3.0+ versions the image can get by below code.

$image_url = wp_get_attachment_image_src( get_post_thumbnail_id( $item->get_product_id() ), 'single-post-thumbnail' );
echo $image_url[0]

I had the same problem and solved it by using the default woocommerce hook to display the product image.

while ( $loop->have_posts() ) : $loop->the_post();
   echo woocommerce_get_product_thumbnail('woocommerce_full_size');
endwhile;

Available parameters:

• woocommerce_thumbnail
• woocommerce_full_size

I did this and it works great

<?php if ( has_post_thumbnail() ) { ?>
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?></a>
<?php } ?>

get_the_post_thumbnail function returns html not url of featured image. You should use get_post_thumbnail_id to get post id of featured image and then use wp_get_attachment_image_src to get url of featured image.

Try this:

<?php
$args = array( 'post_type' => 'product', 'posts_per_page' => 80, 'product_cat' => 'profiler', 'orderby' => 'rand' );

$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>
	<div class="dvThumb col-xs-4 col-sm-3 col-md-3 profiler-select profiler<?php echo the_title(); ?>" data-profile="<?php echo $loop->post->ID; ?>">
		<?php $featured_image = wp_get_attachment_image_src( get_post_thumbnail_id($loop->post->ID)); ?>
		<?php if($featured_image) { ?>
		<img src="<?php $featured_image[0]; ?>" data-id="<?php echo $loop->post->ID; ?>">
		<?php } ?>
		<p><?php the_title(); ?></p>
		<span class="price"><?php echo $product->get_price_html(); ?></span>
	</div>
<?php endwhile; ?>

This should do the trick:

<?php
    $product_meta = get_post_meta($post_id);
    echo wp_get_attachment_image( $product_meta['_thumbnail_id'][0], 'full' );
?>

You can change the parameters according to your needs.
