Best process for paypal IPN and submitting the form

[coupe-r]

Hello everyone,

 

I have a rental application form that gets submitted online and then inserted into the DB.  I now want to allow users to pay the application fee online.

 

My question is, what is the best process for this?

 

Here is what I was thinking:

Fill out the form --- Selecting Credit Card as the payment option --- Pressing the 'Submit' button --- Transferring them to Paypal to complete payment --- On successful payment, insert the application fields into the DB?

 

Is there a better way of doing it?  Since they are leaving my site temporarily, will my php variables for the application still be valid?

 

I've never worked with Paypal IPN before, so any help would be great.  (I would be willing to pay someone for this setup).

 

Thanks
