I have a subscription form on my site. I want the user to be able to pay for their subscription in the following manner.
1) User enters their details in the form and clicks subscribe button (completed)
2) User is directed to paypal to pay (part-completed)
3) User pays and is redirected to site by IPN (part-completed)
4) Response codes are sent back to our website and we display the "Success" or failure message
5) If payment was successful the user's details are saved to the database using wordpress tags wp_insert_user and update_user_meta
6) A password is sent to the user by email
NOTE - I have code samples for parts 5 & 6 that work when completed manually - I need to automate the system, particularily integration with Paypal IPN, so parts 2-4 are most important.
Max budget is $100. Respond with message subject "IPN" to prove you have read this message in full. Please post links to similar work that you have completed.
