Adding MSRP to product page for WooCommerce - php

Question

I'm currently trying to add a new text-field to my product page. I want to display the MSRP price of my products next to the product. Like on the image below. The MSRP should be on where the red line is.
Here is the image
I've done quite a bit of research on the topic. There are a few plugins that would fix the problem. However most of them have either bad reviews or are paid. I've succesfully added a meta field for the MSRP. However when i add a price to this field it doesn't show up on the product page at all.
function bbloomer_display_RRP() {
global $product;
if ( $product->get_type() <> 'variable' && $rrp = get_post_meta( $product->get_id(), 'rrp', true ) )
{
echo '<div class="woocommerce_rrp">';
_e( 'RRP: ', 'woocommerce' );
echo '<span>' . wc_price( $rrp ) . '</span>';
echo '</div>';
}
}
The code above should display the MSRP price on the product page. However it doesn't

Answer 1

Are you adding bbloomer_display_RRP to any hook? The function by itself, won't do anything. Based on your screenshot, I would add it to the woocommerce_template_single_price hook with a priority of 5 so that it will appear just before the price does.
/**
* Add RRP Field to product data metabox
*/
function kia_add_RRP_to_products() {
woocommerce_wp_text_input( array(
'id' => 'rrp',
'class' => 'short wc_input_price',
'label' => __( 'RRP', 'woocommerce' ) . ' (' . get_woocommerce_currency_symbol() . ')',
'data_type' => 'price',
));
}
add_action( 'woocommerce_product_options_pricing', 'kia_add_RRP_to_products' );
/**
* Process, verify and save product data
*
* #param WC_Product $product
*/
function kia_save_RRP( $product ) {
if ( isset( $_POST['rrp'] ) ) {
$rrp = wc_format_decimal( wc_clean( wp_unslash( $_POST['rrp'] ) ) );
$product->update_meta_data( 'rrp', $rrp );
} else {
$product->delete_meta_data( 'rrp' );
}
}
add_action( 'woocommerce_admin_process_product_object', 'kia_save_RRP' );
/**
* Display RRP on front-end in product summary
*/
function kia_display_RRP() {
global $product;
$rrp = '10';
if ( ! $product->is_type( 'variable' ) ) {
$rrp = $product->get_meta( 'rrp', true );
if ( $rrp ) {
echo '<div class="woocommerce_rrp">';
printf( __( 'RRP: %s', 'your-textdomain' ), wc_price( $rrp ) );
echo '</div>';
}
}
}
add_action( 'woocommerce_single_product_summary', 'kia_display_RRP', 5 );
