How to output brands in woocommerce emails to admin & customer ?

See here first https://docs.woothemes.com/document/template-structure/

You can add this to the email template files.

You can get the list of brands with https://codex.www.ads-software.com/Function_Reference/wp_get_post_terms

I can get the output of Brands on a product page using the code below. But I am unable to figure out which hook to use to get the brand for each product in wocommerce email notifications. I’m on Woocommerce 2.6, WordPress latest.

<?php $brands = wp_get_post_terms( $post->ID, 'product_brand', array("fields" => "all") );
  foreach( $brands as $brand ) {
  echo $brand->name;
}?>

Hi Mike,
I added this function into function.php and nothing is happening. Brands are not showing up in the email. Where did I do the mistake ?

function add_brands_to_email () {

  $brands = wp_get_post_terms( $post->ID, 'product_brand', array("fields" => "all") );
    foreach( $brands as $brand ) {
    echo $brand->name;
  }
}
// add the action
add_action( 'woocommerce_order_item_meta_end', 'add_brands_to_email', 10, 3 );

I’m not getting any woocommerce emails after adding that function, Where have I done wrong ?

You probably don’t have $post declared anywhere, so $post->ID is causing an error. You need to get the post/product id using the parameters passed in this hook: https://github.com/woothemes/woocommerce/blob/master/templates/emails/email-order-items.php#L59

If you aren’t comfortable with custom code like this, you might want to consider https://jobs.wordpress.net/ or https://codeable.io/

Stumbled upon this old post of mine, thought of updating how I did this, in case someone comes wondering with this same question. Here is how I did it.
1. Copy the whole woocommerce template plugin into your child theme
/path/to/plugins/woocommerce/templates to /path/to/child-theme/woocommerce/
2. Edit the email-order-items.php in /path/to/child-theme/woocommerce/emails
3. Before the action hook
do_action( 'woocommerce_order_item_meta_end', $item_id, $item, $order, $plain_text );

add this code:

$brands = wp_get_post_terms( $_product->id, 'product_brand', array("fields" => "all") );
    echo '<div class="email-brand"><p><strong>Brand:</strong>' . ' ';
    foreach( $brands as $brand ) {
        echo $brand->name . '  ';
    }
    echo '</p></div>';

_product->id will fetch your productID and pass that as if it is post->ID to wp_get_post_terms(). <div> and <p> are for styling.

This will output the brands list (separated with a space) of each product in woocommerce emails to customers and to store admin.
