web interface questions

These questions have to do with using the web interface. To give more information, i have built a sort of proxy to OG using php and xml parser, so i pass fields to the fmpro using a post instead of using the default html pages that come with OG.

Most things work fine, but there are some funkiness with the scripts such as customer goes to edit account, and if they enter in a credit card, og switches the payment type to CC automatically. I would like to be able to have a customer enter this information but maybe add a pull down or checkbox with whether to switch the automatica payment type or not.

Here are the questions I have so far

1) how do we tell the og script for editing account info to not set the
payment type to "credit card" automatically if there is a credit card
number? what field do we pass to the script to tell it "none" or "credit
card"?

2) is there a list of fields we can pass to the og scripts so that modifying
the web interface is easier to manage? Has anyone compiled a list of modifiable fields to be used with the web interface? This would be great since some of the fields are totally wacky for what they correspond to, ie the "address" field might be called "Broadband 1" or something like that.

3) If a field is left blank, are we suppose to not pass that field to the og
script(s)? it seems that if a field is blank a space is inserted, so for
example when someone edits their account and leaves the override email
address blank, a space is inserted into their account.

4) when someone makes a 1 time payment, is there a way to tell the script(s) to not save the credit card info into their account and not set the payment type to credit card?

 

well can you tell me what field i pass to change "billing type"

can i send "Billing Type" = "None" ? or is it something like "cBilling_Type"?
