    function wptips_woo_price_shortcode( $atts ) {
    $atts = shortcode_atts( array(
        'id' => null,
    ), $atts, 'woocommerce_price' );

    $html = '';

    if( intval( $atts['id'] ) > 0 && function_exists( 'wc_get_product' ) ){
         $_product = wc_get_product( $atts['id'] );
         $html = $_product->get_price();
    }
    return $html;
}
add_shortcode( 'woo_product_price', 'wptips_woo_price_shortcode' );

  • How to add text before or after price in WooCommerce

    You can use the WooCommerce filter woocommerce_get_price_html and woocommerce_cart_item_price to add a string before or after the price in WooCommerce product and cart pages.

    Here is the code that you can copy and paste in your active theme’s functions.php file: 

    function wptips_custom_html_addon_to_price( $price, $product ) {
 $html_price_prefix = '<span class="price-prefix">prefix</span>'; // custom prefix html that you want to add before price
 $html_price_suffix = '<span class="price-suffix"> suffix</span>'; // custom suffix html that you want to add after price

 if ( !empty( $price ) ) {
	 $price = $html_price_prefix . ' ' . $price . ' ' . $html_price_suffix;
	  return $price;
	} else {
	  return $price;
	}
}
add_filter( 'woocommerce_get_price_html', 'wptips_custom_html_addon_to_price', 999, 2 );
add_filter( 'woocommerce_cart_item_price', 'wptips_custom_html_addon_to_price', 999, 2 );

    You can use the above simple code snippet in your active theme, or use the code in a custom plugin to add text next to the price in WooCommerce. You can also add a prefix or suffix HTML or TEXT to the price on the product page and cart page as well.
