PaypalIPN Shop Integration

​

Obsolete

 

good job!!

 

Thank you rosor!

 

Very cool.

 

Thank you!

 

Well done with this, great idea.

 

Way to think ahead of time.

 

can we use this script in ios, osx and android? and is that against apple rules? sorry for asking this stupid question.

 

Questions are never stupid. I am sorry but i have no ios or android device to test it. I also do not know if it is against the apple rules, if you click on one of the offer you will be simply redirected to paypal where you can do or cancel the payment.

 

Nice job!

 

Very nice bro! Be picking this up soon.

 

Thank you ImaGino and Burletech!

 

Nice idea!

 

Thank you!

 

Reduced price to 10$, would be great to get feedback from the one guy who bought it

This is free now!

 

This looks nice, but I really don't want to give out my personal details just to download a free package. Anywhere else you could host it?

 

Just put in fake info. I did.

 

why not put this in the asset store?

 

Can somebody explain how this works a little bit? When a new user registers, where is there info saved? And how do I setup what items can be sold?

 

Well, I don't know.
I will say this, however.

I didn't feel like re-downloading this package (I have in the past, but couldn't find it) so I coded my own for my specific purposes (ties into my own account system).

Here's how Paypal IPN works. After you've set up your merchant account in PayPal, and have it pointing to your IPN script on your website, you give users a specially formatted link (or, in the case of Unity, a button that calls Application.OpenURL).
This link opens a purchase page, where users can log into paypal and buy the item.
Then, after users have logged in and confirmed the purchase, PayPal will contact your IPN script on your website with details about the transaction. After your script confirms that the transaction is legitimate and all the data is correct (among other things), you then do what you want with the data. For instance, in my own IPN setup, I pass the user's account ID in the "custom" field. When my IPN script receives the transaction, it grabs the account ID from the custom field, and updates the account with that ID in my database with the number of credits the user purchased (determined via item name - not the cleanest way, but works. I have a lookup table that maps item name -> number of credits).

That's a VERY basic overview, with a lot of details missing. If that package has documentation, I encourage you to read through it and see what the actual setup steps are and how to use it.

 

Hey thanks for the answer, I appreciate it. In the documentation that is provided, I do not see how to add items to the shop. I am confused how to set up what items can be sold, and also do not understand what is happening with the php files. From looking at the code, I believe the user IDs and Passwords are stored in an SQL database, but I have never programmed any php/sql so this is very confusing

Thanks for your reply, atleast I understand the basics of what is happening. Would you be willing to look at a script if I sent it to you? I'm sure you would know immediately is going on.

 

Well, I would encourage you to start learning PHP. It's a bit... arcane, to say the least, but once you get the hang of it it's actually not that hard.

I bet in your register scripts you'll see some kind of mysql_connect line, this is where it connects to the database. There will probably also be a line where it selects which database to you (you can set up MySQL to host multiple databases).
Probably some lines where it grabs user account information (either $_GET or $_POST, depending), sanitizes it (to prevent against SQL injection), and eventually gets to the bit where it inserts the user account into the database. Probably something like:

Code (csharp):

1.  
2. $SQL = "INSERT INTO AccountsOrWhateverTheTableIsCalled VALUES ( ... )"
3.  

From that you should probably be able to figure out what the account table has to be named, and what values it should contain.

 

Hello, the sql script is included, you need to run it for example in phpmyadmin. Also all other php scripts are included. You have to add the "product" via phpmyadmin for example to the database and also inside unity.

 

how do you use the credits?

 

It is your choice how to use them.

 

how would i make it to where the user can donate a certain amount of credits to an item.

like the user picks an item name and can spend any amount that they have on those items

 

This asset does not include this functionality. You would need to write this by yourself. Something like a shop system where the user can purchase items using credits.

 

is there something im not understanding? after the payment is made. it doesn't post it to the database under payment. only way i know its posted is from my email paypal sends me

 

Thank you for the explaination. So far I understand how IPN works. But my main problem ist: After adding the new items to the user account in the database, how can I tell my unity game that it should update his data from the database? Right now the user gets the new values in the game only after re-login. I don't want to poll my database all the time so how can I notify my game that the payment went well?
