Get value from an input field and pass into update_meta_data as $meta_value

Question

I am building a woocommerce site and I have some input fields the on the product page. one is for recipient email (its for a gift car). Everything works, and the recipient email is saved on the order, but I want to be able to pass the email address to a function to update_meta_data so that I can use in other parts of the code (namely to send out a separate email to the recipient to redeem the card).

here is the function I am trying to use:

add_action('woocommerce_checkout_update_order_meta',function( $order_id, $posted ) {

    $order = wc_get_order( $order_id );
    $order->update_meta_data( 'recipient_email', "[email protected]" );
    $order->save();
} , 10, 2);

Where "joe@acme" is, I want to pass the value from the form. the form is rendered using a custom form plugin. the html of the form looks like this:

<input name="recipient_email" id="recipient_email" data-type="text" data-req="on" data-message="no email" maxlength="255" style="width: 100%; padding: 0px;" type="text">

As I said, the form works to save the recipient email to the order, but not as post meta data, so I don't know how to retrieve and store as a variable that I can use for for other parts of the code.

Answer 1

You can use the $posted parameter to get the right value in your function.

add_action('woocommerce_checkout_update_order_meta',function( $order_id, $posted ) {

$order = wc_get_order( $order_id );
$order->update_meta_data( 'recipient_email', $posted['recipient_email'] );
$order->save();
} , 10, 2);

Verify that $posted is an array not an object with a var_dump on $posted. if it's an object replace $posted['recipient_email'] with $posted->recipient_email

Hope it helps :)

You can use below code in your active theme functions.php file or active child theme

add_action( 'woocommerce_checkout_update_order_meta', 'save_recipient_email_to_order_meta', 10, 2 );

function save_recipient_email_to_order_meta( $order_id, $posted_data ) {
   // Get the recipient email from the posted data
   $recipient_email = isset( $posted_data['recipient_email'] ) ? $posted_data['recipient_email'] : '';

   // Save the recipient email as post meta data for the order
   if ( $recipient_email ) {
      update_post_meta( $order_id, 'recipient_email', $recipient_email );
  }
}

You will get meta data using order_id
$order_id = 123; // Replace 123 with the actual order ID

// Get the recipient email from the order meta data
$recipient_email = get_post_meta( $order_id, 'recipient_email', true );
