Required Field Missing. PHP Paypal REST API -


i'm trying use php paypal rest api. however, seems unable pass list of items through transaction because "required field(s) missing".

$item = new item(); $item->setquantity("1"); $item->setname("stuff"); $item->setprice("305.00"); $item->setcurrency("usd");  $amount = new amount(); $amount->setcurrency("usd"); $amount->settotal("305.00");  $item_list = new itemlist(); $item_list->setitems(array($item));  $transaction = new transaction(); $transaction->setamount($amount); $transaction->setdescription("this incredibly awesome."); $transaction->setitem_list($item_list);

i've filled fields paypal's documentation deems "required" per "common objects" in documentation (https://developer.paypal.com/webapps/developer/docs/api/#common-objects). being thrown error when try redirect paypal start transaction:

exception: got http response code 400 when accessing https://api.sandbox.paypal.com/v1/payments/payment. string(269) "{"name":"validation_error","details":[{"field":"transactions[0].item_list.items[0].sku","issue":"required field missing"}],"message":"invalid request - see details","information_link":"https://developer.paypal.com/docs/api/#validation_error","debug_id":"9e292fc3a312d"}"

when comment out $transaction->setitem_list($item_list);, works properly. it's obvious missing in item list or item. can't see what.

any ideas?

the error point this:

transactions[0].item_list.items[0].sku

this filed seems required think need put sku in item array let's it: try add:

$item->setsku("codehere");

after

$item->setcurrency("usd");

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
