[eluser]the_unforgiven[/eluser]
Done a test page to var_dump() each varible and here's the output so the vars are working just not with domPDF

Code:

array(9) { ["order_id"]=> string(2) "14" ["product_id"]=> string(1) "7" ["customers_id"]=> string(1) "1" ["item_ordered"]=> string(11) "New Product" ["qty"]=> string(2) "12" ["order_amount"]=> string(5) "23.99" ["order_date"]=> string(19) "2012-12-18 19:19:34" ["order_status"]=> string(9) "Cancelled" ["other"]=> string(0) "" }

array(29) { ["id"]=> string(1) "1" ["fullname"]=> string(11) "A Customer" ["firstname"]=> string(3) "A" ["lastname"]=> string(7) "Customer" ["address1"]=> string(27) "10 Downing Street " ["address2"]=> string(8) "Address Somewhere" ["town"]=> string(9) "Some Town" ["city"]=> string(6) "A City" ["county"]=> string(8) "A County" ["country"]=> string(14) "United Kingdom" ["postcode"]=> string(7) "AS09ED" ["email"]=> string(22) "[email protected]" ["username"]=> string(8) "testuser" ["password"]=> string(40) "516fa3fd6bf97a4b3ff09ec93877d39005a7996d" ["tel"]=> string(11) "01122334455" ["pay_method"]=> string(3) "---" ["status"]=> string(1) "1" ["activation_code"]=> string(31) "wppBXNMGaYn3bnA4leHXDwxMmWLocqO" ["activated"]=> string(1) "1" ["created"]=> string(10) "2013-01-01" ["order_id"]=> NULL ["product_id"]=> NULL ["customers_id"]=> NULL ["item_ordered"]=> NULL ["qty"]=> NULL ["order_amount"]=> NULL ["order_date"]=> NULL ["order_status"]=> NULL ["other"]=> NULL }
