PAP has a standard signup form here, but it allows you to make your own signup form in HTML and place it anywhere you want.
The HTML signup form must be sent to /affiliates/signup.php after signup. Then there are two modes of operations.
If you don't include the errorUrl,successUrl hidden fields, the form will be processed by standard signup form.
If there are some errors, they will be displayed in the standard signup form.
If you want to be sent back to the HTML signup form in case of error, you have to add hidden field errorUrl to the form and file have to be PHP!
Then the error messages and all values will be sent back by POST method to the URL you specified in errorUrl.
Possible HTML form parameters (as hidden fields)

URL where the data should be sent when signup is successful. It will override any setting from merchant panel. It can be "thank you for signup" page.
