Add a custom order note programmatically in Woocom

问题:

In woocommerce I am trying to add a custom order note in the admin order edit pages through php (so programmatically). I haven't find the way yet.

Any help will be appreciated.

From a dynamic Order Id you can use WC_Order add_order_note() method this way:

// If you don't have the WC_Order object (from a dynamic $order_id)
$order = wc_get_order(  $order_id );

// The text for the note
$note = __("This is my note's text…");

// Add the note
$order->add_order_note( $note );

Tested and works.

Thank you guys I was trying to find a way to add the notes to a new order. I was looking for the right hook using the solution that @LoicTheAztec posted. This is the solution that worked for me hope it helps someone else out there.

add this to the Functions.php file

add_action( 'woocommerce_new_order', 'add_engraving_notes',  1, 1  );

function add_engraving_notes( $order_id ) {
 //note this line is different 
 //because I already have the ID from the hook I am using.
 $order = new WC_Order( $order_id ); 

 // The text for the note
 $note = __("Custom Order Note Here");

 // Add the note
 $order->add_order_note( $note );

 // Save the data
 $order->save();
}

This code will do trick for you add code in functions.php

                    add_action('woocommerce_after_order_notes', 'customise_checkout_field');

                    function customise_checkout_field($checkout)
                    {
                    echo '<div id="customise_checkout_field"><h2>' . __('Heading') . '</h2>';
                    woocommerce_form_field('customised_field_name', array(
                    'type' => 'text',
                    'class' => array(
                    'my-field-class form-row-wide'
                    ) ,
                    'label' => __('Customise Additional Field') ,
                    'placeholder' => __('Guidence') ,
                    'required' => true,
                    ) , $checkout->get_value('customised_field_name'));
                    echo '</div>';
                    }

For data validation of the custom field use the code given below:

                    add_action('woocommerce_checkout_process', 'customise_checkout_field_process');

                    function customise_checkout_field_process()
                    {
                        // if the field is set, if not then show an error message.
                        if (!$_POST['customised_field_name']) wc_add_notice(__('Please enter value.') , 'error');
                    }

Update value of field

                    add_action('woocommerce_checkout_update_order_meta', 'customise_checkout_field_update_order_meta');

                    function customise_checkout_field_update_order_meta($order_id)
                    {
                        if (!empty($_POST['customised_field_name'])) {
                            update_post_meta($order_id, 'Some Field', sanitize_text_field($_POST['customised_field_name']));
                        }
                    }
