Aptimus Advertiser Specifications

Order Processor Validation

Front End Validation
The front end validation attempts to facilitate the user into identifying mistakes made when entering data. The front end validation does not take the approach of preventing hackers but rather to help the user identify where incorrect data has been entered. The user will be shown immediately where errors lie before forwarding to any other page or sending information back to Aptimus.

Objectives for Front End Validation:

Check for required fields.
Check that at least one offer is selected.
Check generic field names and values.

Required Fields
As an offer is displayed on the browser each question has been flagged if it is required or not. This information is stored in the database and gets sent to the browser with the offer. When the user submits the data, the javascript function "checkRequiredFields( frm )" iterates through each question and determines if it is required. If it is required, then data must exist for that question.

At least one offer is selected
Nothing will get submitted to the Aptimus servers if the user has unselected the offers that they had originally checked.
