I have a membership application form that collects basic demographic data. Once the form is submitted, I use PHP to insert the data into a database and then redirect the user to Paypal for membership payment. I would like to add a field to each user record that indicates whether or not a payment has been posted. Is there a way Paypal can pass back a confirmation that I can use to update each membership record?
Yes, check this out is called IPN is provided by paypal, this is how it works

I want to create a page that lists class, allows the user to choose a course + fill out their name and email, lets the user pay with paypal and if they paid the form writes the data to a database.
I know how to make an HTML and PHP form with the required fields, I know how to write data to a database, I researhed how to create a paypal business account to accept payments, but how do I write the form data to the database AFTER the paypal page? The browser is redirected to paypal's site for the payment isn't it?.

how can I keep variables from page 1 and use them on page 3 to write to the database?
I would recommend implementing this server-side checkout pattern: https://developer.paypal.com/demo/checkout/#/pattern/server
API calls happen on your server to set up and capture the transaction: https://developer.paypal.com/docs/checkout/reference/server-integration/
When the API call to capture returns success, that is when you can immediately write the successful registration record in your database, and show the confirmation to the user.
I am trying to integrate Paypal payment with a form registration. For example, a user would enter their information into form fields, press "register" and then they would be taken to Paypal where they pay a fee, upon payment the information they've submitted is posted in a file. I already have the information posting successfully into a file using a php, but now I want the process to wait for payment validation before posting. Is that possible?
I've got a question about the PayPal transaction system. I try to implement a paypal shopping cart in my website. But what I want to do is I want to have like "PrePaid credits" on my website. So when the transaction successfully processed. A database value will change given the credits the user wanted to buy.
I dont have a idea on what to search for. I only know standard php. Not any modification such as paypal. So can anyone give me a code/website where I can find some usefull code?
Thank you!
PS: If you have any suggestions on the post to make it even clearer please comment.
You would use the PayPal IPN (Instant Payment Notification), so a user would click 'Purchase x credits' on your site (you would have a custom field with the user's ID, it would then take them to PayPal via custom form you put together, that form has a return URL which after the payment has been successfully made, would return them to that URL, and you would make that success return URL update your database with the details.
So on a successful return from PayPal, your page would update the database with the custom value (User ID) we initially passed in the form along with the amount of credits they purchase (this can be passed via custom value OR you could just use PayPal's callback information returned with the query (it'll be posted to your page from PayPal I believe).

Am I correct in my understanding that I can only pass-through one custom variable from a form I create to PayPal using IPN?
I have my IPN script up and running with no issues. However, upon payment notification I need to store information input by the user from a form on my site into a MySQL database.
In this specific case its for a sports league registration form. The user fills out info regarding their team (i.e. Team name, League, ect..) then pays the league fee via PayPal. Upon verification I'd like to store their team name, the league they're signing up for and other info I need to collect in my database. But since I can only pass-through one custom variable from my form through the PayPal IPN process, I'm a bit stumped.
I've read other posts about storing the info immediately in the database, then marking it 'paid' upon verification. However, how could I accomplish this since when the user clicks Pay Now, the form action performed is the PayPal payment process (as opposed to an insert statement I create). Where would I perform a database INSERT with the posted form information?
Tips or advice would be appreciated!

Perform the INSERT before sending the customer to PayPal. Before that, define a unique random key for the transaction. Put that key
into the database record that's being inserted and
pass it to PayPal's IPN.
Once notification comes back from PayPal, you can use the key to identify the record (with all the info already in it) and mark it paid.
It seems that Paypal limits what what information can be retrieved by the paypal IPN php file after the user pays. I want users to be able to make an username and password that they will use to log in to my website before they click the paypal checkout button. After they pay, my paypal IPN php file will retrieve their username and password and place them into my mysql database. Is this possible? I want to make registration as easy as possible for the users.
Thanks in advance
there are a couple of custom fields that you can add to your form that paypal will return no matter what you sue them. however i would recommend saving the data locally, before sending the rest of to paypal, to do this you either nee to use AJAX to submit part of the form to a php script or pre-possessing the form data before sending to paypal via curl.
