Display product optional cost in Woocommerce in order details - php

Question

Based on "Add a checkbox on single product pages that adds an additional cost in Woocommerce" answer code, I am trying to add an "extra warranty" option to my products (checkbox in product page):
/*
* add warrenty
*/
// Backend: Additional pricing option custom field
add_action( 'woocommerce_product_options_pricing', 'wc_cost_product_field' );
function wc_cost_product_field() {
woocommerce_wp_text_input( array(
'id' => '_warrenty_price',
'class' => 'wc_input_price short',
'label' => __( 'Warrenty', 'woocommerce' ) . ' (' . get_woocommerce_currency_symbol() . ')'
));
}
// Backend: Saving product pricing option custom field value
add_action( 'woocommerce_admin_process_product_object', 'save_product_custom_meta_data', 100, 1 );
function save_product_custom_meta_data( $product ){
if ( isset( $_POST['_warrenty_price'] ) )
$product->update_meta_data( '_warrenty_price', sanitize_text_field($_POST['_warrenty_price']) );
}
// Front: Add a text input field inside the add to cart form on single product page
add_action('woocommerce_single_product_summary','add_warrenty_price_option_to_single_product', 2 );
function add_warrenty_price_option_to_single_product(){
global $product;
if( $product->is_type('variable') || ! $product->get_meta( '_warrenty_price' ) ) return;
add_action('woocommerce_before_add_to_cart_button', 'product_option_custom_field', 30 );
}
function product_option_custom_field(){
global $product;
$active_price = (float) $product->get_price();
$warrenty_price = (float) $product->get_meta( '_warrenty_price' );
$warrenty_price_html = strip_tags( wc_price( wc_get_price_to_display( $product, array('price' => $warrenty_price ) ) ) );
$active_price_html = wc_price( wc_get_price_to_display( $product ) );
$disp_price_sum_html = wc_price( wc_get_price_to_display( $product, array('price' => $active_price + $warrenty_price ) ) );
echo '<div class="hidden-field">
<p class="form-row form-row-wide" id="warrenty_option_field" data-priority="">
<span class="woocommerce-input-wrapper"><span class="war-title"> ' . __("Warrenty price:", "Woocommerce") .
'</span><label class="checkbox"><input type="checkbox" class="input-checkbox " name="warrenty_option" id="warrenty_option" value="1"> Add Warrenty for ' . $warrenty_price_html .
'</label></span></p>
<input type="hidden" name="warrenty_price" value="' . $warrenty_price . '">
<input type="hidden" name="active_price" value="' . $active_price . '"></div>';
// Jquery: Update displayed price
?>
<script type="text/javascript">
jQuery(function($) {
var cb = 'input[name="warrenty_option"]'
pp = 'p.price';
// On change / select a variation
$('form.cart').on( 'change', cb, function(){
if( $(cb).prop('checked') === true )
$(pp).html('<?php echo $disp_price_sum_html; ?>');
else
$(pp).html('<?php echo $active_price_html; ?>');
})
});
</script>
<?php
}
// Front: Calculate new item price and add it as custom cart item data
add_filter('woocommerce_add_cart_item_data', 'add_custom_product_data', 10, 3);
function add_custom_product_data( $cart_item_data, $product_id, $variation_id ) {
if (isset($_POST['warrenty_option']) && !empty($_POST['warrenty_option'])) {
$cart_item_data['new_price'] = (float) ($_POST['active_price'] + $_POST['warrenty_price']);
$cart_item_data['warrenty_price'] = (float) $_POST['warrenty_price'];
$cart_item_data['active_price'] = (float) $_POST['active_price'];
$cart_item_data['unique_key'] = md5(microtime().rand());
}
return $cart_item_data;
}
// Front: Set the new calculated cart item price
add_action('woocommerce_before_calculate_totals', 'extra_price_add_custom_price', 20, 1);
function extra_price_add_custom_price($cart) {
if (is_admin() && !defined('DOING_AJAX'))
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
foreach($cart->get_cart() as $cart_item) {
if (isset($cart_item['new_price']))
$cart_item['data']->set_price((float) $cart_item['new_price']);
}
}
// Front: Display option in cart item
add_filter('woocommerce_get_item_data', 'display_custom_item_data', 10, 2);
function display_custom_item_data($cart_item_data, $cart_item) {
if (isset($cart_item['warrenty_price'])) {
$cart_item_data[] = array(
'name' => __("Extra Warrenty", "woocommerce"),
'value' => strip_tags( '+ ' . wc_price( wc_get_price_to_display( $cart_item['data'], array('price' => $cart_item['warrenty_price'] ) ) ) )
);
}
return $cart_item_data;
}
It's work fine and the price is calculated in the payment.
The problem is that the field value doesn't appear in the order details table (and email notifications). So I don't have a way to know if the customer paid for the warranty or not (except calculated the final price of the product).
What should I add to the code so that the field will appear in the order details and mails?

Answer 1

You just need this little peace of code to display this warranty option everywhere:
// Save warranty as order item custom meta data and display it everywhere
add_action('woocommerce_checkout_create_order_line_item', 'save_order_item_product_warranty', 10, 4 );
function save_order_item_product_warranty( $item, $cart_item_key, $values, $order ) {
if( isset($values['warrenty_price']) && $values['warrenty_price'] > 0 ) {
$key = __("Extra Warrenty", "woocommerce");
$value = strip_tags( '+ '. wc_price( wc_get_price_to_display( $values['data'], array('price' => $values['warrenty_price']) ) ) );
$item->update_meta_data( $key, $value );
}
}
Code goes in function.php file of your active child theme (or active theme). tested and works.
In order received page (and all other order pages):
In admin order pages:
In email notifications:

Answer 2

add_action( 'woocommerce_admin_order_data_after_order_details', 'warrenty_price_order_meta_general' );
function warrenty_price_order_meta_general( $order ){ ?>
<br class="clear" />
<h4>Gift Order Edit</h4>
<?php
/*
* get all the meta data values we need
*/
$_warrenty_price = get_post_meta( $order->get_id(), '_warrenty_price', true );
?>
<div class="address">
<p><strong>Warranty</strong></p>
<?php
if( $_warrenty_price ) :
?>
<p><strong>Price:</strong> <?php echo $_warrenty_price ?></p>
<?php
endif;
?>
</div>
<?php } ?>
For Email
add_action('woocommerce_email_order_meta', 'warrenty_price_email_order_meta', 10, 3);
function warrenty_price_email_order_meta($order_obj, $sent_to_admin, $plain_text) {
$warrenty_price = get_post_meta($order_obj->get_id(), '_warrenty_price', true);
if (empty($warrenty_price))
return;
if ($plain_text === false) {
echo '<h2>Warranty</h2>
<ul>
<li><strong>Price:</strong> ' . $warrenty_price . '</li>
</ul>';
} else {
echo "Warranty\n
Price: $warrenty_price";
}
}
