Title: Should I accept payments without a callback URL? Post by: PBmining on December 29, 2013, 03:47:51 AM When implementing a payment system, Blockchain.info uses callback URLs with their PHP examples.
I only understand its use of sending the user to a confirmation page after ordering. I have read that it is for added security though too, but I don't see how. What if I chose not to use it?

If you choose not to, then blockchain.info will not send any message back to your webpage and you may not know when the payment has reached. If you do not use callbacks, your user would be stuck on the payment confirmation page until someone manually agrees to move him forward. The added security is that it verifies the payment before sending the customer forward. Title: Re: Should I accept payments without a callback URL?

We can't tell why things aren't being added to the DB unless you show us the code that does the actual adding.

Title: Re: Should I accept payments without a callback URL? Post by: Rannasha on January 05, 2014, 07:33:15 PM For debugging, you should make the script display all queries that are executed. You can then find the exact query it tries to run to insert data into the pending table and then use something like PHPMyAdmin or the mysql commandline client to run this query and get more detailed error messages.
In general it is a good idea to abstract away from calling mysql_query() directly (not to mention that it is deprecated and should be replaced by mysqli_query()). Create a new function: Code: function do_query($query_string) |
