Working with Drupal commerce entities using entity_metadata_wrapper. Just a bunch of exampled copied from the web or added by me. will keep adding over time. now more then just commerce entities
<?php
// Basics
// Get a value.
$value = $wrapper->field_x->value();
// If the field is a reference field you will get the field object
// To get the wrapper back use:
$wrapper_b = $wrapper->field_ref;
// To set a value.
$wrapper->field_x = $value;
// Or
$wrapper->field_x->set($value);
// To save the entity
$wrapper->save();
// order.
$order_wrapper = entity_metadata_wrapper('commerce_order', $order);
// Order id.
$order_id = order_wrapper->order_id->value();
// Order Number.
$order_id = order_wrapper->order_number->value();
// User detils.
$uid = $order->uid;
$email = $order->mail;
$user = user_load_by_mail($email);
if ($user) {
$u_wrapper = entity_metadata_wrapper('user', $user);
$u_wrapper->field_xxx = $x;
$u_wrapper->save();
}
// order total object

// subtotal without vat

// total tax (in this case vat 20%)
$total_vat = commerce_price_component_total($order_total , 'tax|vat_20');
// subtotal with vat

Took an hour of Googling to find the answer on how to reference an EMW value() when it's an array - you had the answer I was looking for with your $price_amount example on line 146! I knew there was a way, thanks!

Thank you so much for this! I spent way too much time yesterday poking at EntityFieldQuery and EntityMetadataWrapper configurations to try to get order subtotal data. I wish this page had come up much higher in my Google searches at the time!
