Trigger action when order is processed

If you would like to trigger an action, e.g. sending a custom email, depending on the value of a specific field, you can do something like this:

	<?php
	/**
	* Trigger an action when an add-on field is present in an order
	* Note that you will need to change the values for $field_id and $value below
	*/
	function prefix_pewc_after_create_product_extra( $add_on_id, $order, $field ) {

	$field_id = 1234;
	$value = '__checked__';
	// Check specific field ID is checked
	if( $field['field_id'] == $field_id && $field['value'] == $value ) {
	// Do our action here
	prefix_send_custom_email();
	}

	}
	add_action( 'pewc_after_create_product_extra', 'prefix_pewc_after_create_product_extra', 10, 3 );

	/**
	* Send an email when an add-on field is present in an order
	* You'll need to change the values for $to, $subject and $content below
	*/
	function prefix_send_custom_email() {

	$to = 'you@youremail.com';
	$subject = 'Your Subject Line';
	$content = 'Add your content here.';

	ob_start();
	wc_get_template( 'emails/email-header.php', array( 'email_heading' => $subject ) );
	$email = ob_get_clean();
	$email .= $content;
	wc_get_template( 'emails/email-footer.php' );
	$email .= ob_get_clean();

	wc_mail( $to, $subject, $email );

	}

The code above checks each field in an order for a specific ID and a specific value. In this example, the field ID is 1234, the field type is a checkbox, so we’re checking for ‘__checked__’ as the field value. You can modify this as you wish.

In the second function, you’ll need to update the values for $to, $subject and $content depending on who you want to email and what you want to say.

Here’s how to add the snippet.
