Woo-commerce Variable Regular and Sale price - categories

Question

I am trying to display the regular and sale price of a variable product. I know it can be achieved from get_post_meta( $post->ID, '_regular_price', true); but it isnt working in variable products only a simple product.
I looked into the classes and also saw that woocommerce updates the post meta of _regular_price itself when storing a variable product price.
Is there anything I am missing?
Thanks

Answer 1

The best code for solve this is:
#Step 1: Get product varations
$available_variations = $product->get_available_variations();
#Step 2: Get product variation id
$variation_id=$available_variations[0]['variation_id']; // Getting the variable id of just the 1st product. You can loop $available_variations to get info about each variation.
#Step 3: Create the variable product object
$variable_product1= new WC_Product_Variation( $variation_id );
#Step 4: You have the data. Have fun :)
$regular_price = $variable_product1 ->regular_price;
$sales_price = $variable_product1 ->sale_price;

If you don't have any variation in your product then, you can simple get product price using product ID like:-
add_action('init', 'test');
function test() {
global $woocommerce;
$product = new WC_Product(268);
echo $product->get_price();
}
If product have variation and each variation have different price then need to get price using variation ID.

That's because variable product is not keeping any price information itself but it is the parent of another kind of child posts named "product_variation" each having their own price and variation information. So if you want to do something on price of variable products in a WP_Query loop you have to filter your loop through post_type => 'product_variation' and then you can access their parent id from their post_parent property for getting other related information of those variable products variations such as name, description, images, ...
Here is an example:
$query = new WP_Query(array(
'post_type' => 'product_variation', // <<== here is the answer
'posts_per_page' => 5,
'post_status' => 'publish',
'orderby' => 'meta_value_num',
'meta_key' => '_price',
'order' => 'asc',
));
while ($query->have_posts()) {
$query->the_post();
$pid = $query->post->ID;
$parent = $query->post->post_parent;
$price = get_post_meta($pid, '_price', true);
$regular_price = get_post_meta($pid, '_regular_price', true);
$sale_price = get_post_meta($pid, '_sale_price', true);
$title_product = get_the_title($parent);
$title_variation = get_the_title($pid);
echo "$title_variation: $price <br />";
}
