How to display woocommerce sale price or regular price if there is no sale price

Question

I'm using a woocommerce product addons plugin where I would like to display the price of a product in my dropdown section of the addons. Currently the code I have is this

    <?php
$loop = 0;
$current_value = isset( $_POST['addon-' . sanitize_title( $addon['field-name'] ) ] ) ? wc_clean( $_POST[ 'addon-' . sanitize_title( $addon['field-name'] ) ] ) : '';
global $product;
?>
<p class="form-row form-row-wide addon-wrap-<?php echo sanitize_title( $addon['field-name'] ); ?>">
    <select class="addon addon-select" name="addon-<?php echo sanitize_title( $addon['field-name'] ); ?>">

        <?php if ( ! isset( $addon['required'] ) ) : ?>
            <option value=""><?php _e('None', 'woocommerce-product-addons'); ?></option>
        <?php else : ?>
            <!--<option value=""><?php _e('Select an option...', 'woocommerce-product-addons'); ?></option>-->
        <?php endif; ?>

        <?php foreach ( $addon['options'] as $i => $option ) :
            $loop ++;
            $price = apply_filters( 'woocommerce_product_addons_option_price',
                $option['price'] > 0 ? ' + ' . wc_price( get_product_addon_price_for_display( $option['price'] ) ) . '' : '',
                $option,
                $i,
                'select'
            );
            ?>
            <option data-raw-price="<?php echo esc_attr( $option['price'] ); ?>" data-price="<?php echo get_product_addon_price_for_display( $option['price'] ); ?>" value="<?php echo sanitize_title( $option['label'] ) . '-' . $loop; ?>" <?php selected( $current_value, sanitize_title( $option['label'] ) . '-' . $loop ); ?>><?php echo wptexturize( $option['label'] . ' (' ); echo balanceTags($product->get_price_html()) . $price ?>)</option>
        <?php endforeach; ?>

    </select>
</p>

I'm using this echo

$product->get_price_html()

what this does though is display the $"sale price" $"price" but I just want to display just the sale price or just the product price if there is no sale price. Looking at the code below, how would I accomplish this?

Answer 1

That's what works for me with Wordpress 5.1 and WooCommerce 3.5.5 :

                $price = get_post_meta( get_the_ID(), '_regular_price', true);
                $price_sale = get_post_meta( get_the_ID(), '_sale_price', true);
                if ($price_sale !== "") {
                    echo $price_sale;
                } else {
                    echo $price;
                }

Answer 2

Pretty simple. We'll write a custom function that will first be sure on that if the product is on sale or not. Then it'll return regular or sale price based on the sale condition it defined previously. So the function will be:

/**
 * Returns product price based on sales.
 * 
 * @return string
 */
function the_dramatist_price_show() {
    global $product;
    if( $product->is_on_sale() ) {
        return $product->get_sale_price();
    }
    return $product->get_regular_price();
}

Now call this function the_dramatist_price_show() instead of $product->get_price_html(). You'll get the price based on is on sale or not without currency symbol.

Hope that helps.
