php - Woocommerce purchase note? -

I think I'm forgetting something here clearly: I include the pruchase note in the customer-full Trying to get -order.php so that the customer receives the note with confirmation of purchase but I have failed miserably.

Here's what I tried:

    
 And this  
    
 And this:  
  & lt ;? Php $ purchase_note = get_post_meta ($ _product-> id, '_purchase_note', is true)): echo '& lt; Td class = "product-buy-note" & gt; '. Apply_filters ('the_content', $ purchase_note) '& lt; / TD & gt; '; ? & Gt;   
 And this:  
  & lt ;? Php if ($ order- & gt; position == 'full' || $ order- & gt; position = = 'processing') {if ($ buy_note = get_post_meta ($ _product- & gt; id, '_purchase_note' True)) echo '& lt; Div class = "product-buy-note" & gt; & Lt; Div & gt; . Apply_filters ('the_content', $ purchase_note) '& lt; / Div & gt; & Lt; / Div & gt; '; }? & Gt;   
 Anything starts working  
 It appears on the page received from the order but the order confirmation will not be shown on the email. Any help is very much appreciated, is it open for any other method to get the note to the customer on the purchase, like maybe the custom meta value?   
 
 
 It's been a while, but  $ order-> Use the  $ buy_note = get_post_meta ($ _product- & gt; id, '_purchase_note') instead of the customer_not ;
