    Paypal subscription registration PHP

    I need someone to write a registration form that creates a user account upon a successful transaction.

    The script would ask for the credit card number, the users name, address, zip, etc and send it to paypal without ever sending the user to paypal. None of the payment information would be stored locally but other information such as name, address, e-mail, password, etc will be requested on another part of the form.

    Once the transaction has gone through successfully the user will automatically be made an account on the site.

    I already have the user database setup and what not I just need someone who knows the Paypal API.

    It needs to be done in PHP.

    So, how much would something like this run me?

    Do you have a Merchant account and an SSL certificate to secure you're web server? If so, I would estimate that it would take an experienced programmer 3 - 5 hours to implement. Depending on rate, I'd say that's a $150 - $600 job.

    Okay, if I send them to paypal to to make the payment and then get a response from paypal upon a successful transaction I wouldn't need any security certificates would I? Is sending them to paypal and then back again possible without losing their registration information?

    Yes, you'll need to use their IPN (Instant Payment Notification) service to accomplish this. If you're interested, I can provide you with a quote to do this. Just PM me.

    Hey,

    I have a lot of experience working with the paypal API, especially IPN (which is what you will need).

    As already mentioned, 3-5 hours is a rough time frame which I would also quote, except $150 - $600 is a bit much (especially since you can spend maybe a day to work through examples on the net to accomplish the same thing).

    I can perform the requested task, i.e. write an IPN script and implement the paypal API into your site for $100USD. If you are interested, please send me a PM.

    I have found the the best integration of paypal in php...i cant find any attachment tag here so i m pasting it here..i hope it will help you. I have commented out which will help you to learn the working.

    <?php

    /** PayPal IPN Script
    *
    * See https://cms.paypal.com/us/cgi-bin/?c...ntpaymentnotif
    * for a lot of good information about IPN
    *
    * This script requires a MySQL database with
    * the appropriate tables created. See paypal_ipn.sql
    *
    * Brief overview of how IPN works:
    *
    * After a paypal sale is completed AND the seller has
    * setup PayPal Instant Payment Notification, Paypal sends
    * information about the transaction to this script.
    *
    * Once this script receives the information from PayPal, it
    * sends the same information back to PayPal. PayPal verifies
    * that the information this script sent back matches
    * what was PayPal originally sent. If it matches, PayPal
    * sends 'VERIFIED' back to this script. Once 'VERIFIED' is
    * received, you can be sure that a legitimate transaction took
    * place.
    *
    * If it does not match, or PayPal did not send any information
    * to this script,
    *
    * This script must be placed in a web accessible directory
    * and PayPal must know the location of this script. PayPal is
    * informed of the location of this script when the seller
    * sets up Instant Payment Notification.
    *
    * You can look at the long list of $_POST[''] variables below
    * to see what potentially could be sent to this script. Or see
    * https://www.paypal.com/IntegrationCe...reference.html
    *
    * The base of this script is provided by PayPal at
    * https://www.paypal.com/cgi-bin/websc...n-code-outside
    * and
    * https://www.paypaltech.com/SG2/
    *
    * These scripts were modified and commented by Jason DeBord www.jasondebord.net
    *
