I've been trying to write my own shipping module based on this tutorial. The 'payment method' pane doesn't pick up all the accessorial information until the shipping quote is recalculated. Moving on to the 'review' page exposes a repeated error that was caused by the request for a shipping quote done via ajax on the previous page:
warning: in_array() expects parameter 2 to be array, null given in .../ubercart/shipping/uc_quote/uc_quote.module on line 351.
Obviously this is a very effective way of frightening off customers.
Line 351 (in_array($line_item['title'], $accessorials)) is asking for the $accessorials array, which I've defined correctly in my module, but which isn't being seen by this function because it looks for $accessorials with
$accessorials = $methods[$settings['method']]['quote']['accessorials'];
When I use dpr($settings), I find that it is an array containing two arrays, each pertaining to shipping quotes that have been deleted and had their methods disabled and uninstalled: ucflatrate_1 and minpercentrate_2.
Where is this information coming from?
How can I delete it, or replace it with my own?
My module code is below. I'm really stressing about this one.
