Answer 2

I have two types of code for done this thing
<!-- Get WooCommerce On-Sale Products fetch -->
<ul class="get-onsale-product">
<?php
$args_for_onsale_product = array(
'post_type' => 'product',
'posts_per_page' => 4, //If you want all the post replace 4 with -1.
'meta_query' => array(
'relation' => 'OR',
array( // Simple products type
'key' => '_sale_price',
'value' => 0,
'compare' => '>',
'type' => 'numeric'
),
array( // Variable products type
'key' => '_min_variation_sale_price',
'value' => 0,
'compare' => '>',
'type' => 'numeric'
)
)
);
$onsale_product_items = new WP_Query( $args_for_onsale_product );
if ( $onsale_product_items->have_posts() ) {
while ( $onsale_product_items->have_posts() ) : $onsale_product_items->the_post();
woocommerce_get_template_part( 'content', 'product' );
endwhile;
} else {
echo __( 'Sorry We have no products.' );
}
wp_reset_postdata();
?>
</ul>
<!-- End WooCommerce On-Sale Products fetch -->
And second is following, Before you getting this code please review this link
<!-- Get WooCommerce On-Sale Products fetch -->
<ul class="get-onsale-product">
<?php
$args_for_onsale_product = array(
'post_type' => 'product',
'posts_per_page' => 4,
'post__in' => wc_get_product_ids_on_sale(),
);
$onsale_product_items = new WP_Query( $args_for_onsale_product );
if ( $onsale_product_items->have_posts() ) {
while ( $onsale_product_items->have_posts() ) : $onsale_product_items->the_post();
woocommerce_get_template_part( 'content', 'product' );
endwhile;
} else {
echo __( 'Sorry We have no products.' );
}
wp_reset_postdata();
?>
</ul>
<!-- End WooCommerce On-Sale Products fetch -->

Answer 3

You can use following to check if product has sale price:
$sale_price = get_post_meta( $product_id, '_sale_price', true);
If the $sale_price is greater than 0 and not empty, the product is on sale.
Hope this helps!

Answer 4

$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => '_sale_price',
'value' => 0,
'compare' => '>'
)
),
);
$query = new WP_Query($args);
if ($query->have_posts()) :
echo '<ul class="owl-carousel">';
$products_onsale = array();
while ($query->have_posts()) : $query->the_post();
echo 'on sale';
endwhile;
echo '</ul>';
print_r($products_onsale);
endif;
It will fetch only products with sale price greater than zero ( onsale )
