Function Description
|
If the script has been called by a previous invocation of this same script as determined by the value of the Submit button being “Apply Receipt”:
-
Create a new Receipt record with the values of the Invoice_Number hidden field, the User_Number for this invoice, the Receipt_Date being the current date, the Receipt_Amount being the amount entered from the CGI form, the Receipt_Payment_Type being the value entered from the CGI form, and the Receipt_EnteredBy field being set to REMOTE_USER.
-
If the sum of a Receipt_Amounts in the Receipt table where the Invoice_Number corresponds to the Invoice_Number passed through the CGI form is equal to or greater than the value of the Invoice record’s Invoice_Amount for this Invoice_Number, then set the User_Expiry_Date one year past its current date. (i.e. the Invoice has been paid in full).
For all invocations through this script, even the first, perform the following steps:
-
Get a list of all Invoices from the Invoice table where the User_IsActive = ‘Active’ of the corresponding User_Number and where the sum of all Receipt_Amounts in the Receipt table with this Invoice_Number is less than the Invoice_Amount (i.e. the invoice has not been fully paid).
-
Display a table to the volunteer. For each Invoice returned in step 1, create a row in a table that contains a form. Set the Invoice_Number as a hidden field within each form.
-
Each row will also include: the User’s first and last name, the User’s username, and the value of the User_Since, User_Expiry_Date, and the value of the corresponding Member_Type field in the corresponding Member table. Also display the Invoice_Date, the Invoiced_Medium, the Invoice_Amount, and the sum of any Receipt_Amounts already applied against the Invoice. Present a textfield with the default value set to the difference of the Invoice_Amount less the sum of all Receipt_Amounts applied against this Invoice. Display a radio button array with the values “Cash”, “Cheque”, “In-Kind”, “Visa”, and “MasterCard”. Each row will also include a submit button with the name “Apply Receipt”
