account advance always browser business buyer buyers cart checkout code coding customer doesn effect firefox help log login multiple net payment paypal problem programming purchase send service shopping show site system testing times type web website

I have a web 2.0 site that I am integrating with a shopping cart that lets the user build a business card and then purchase it. I am currently using Paypal's Shopping Cart but will be switching to e-junkie shortly (currently trial).

I am however, running into the same exact problem I had with paypal. When user A logs out, and user B logs in, user B can see user A's cart.

What am I doing wrong?

If you need code just let me know. I am currently using PHP with session management.

Thanks in advance

I'm not sure what you mean about buyers logging in/out, since neither our cart nor PayPal's cart uses any login session routine until the buyer takes their cart to checkout, where they log into their account on payment processor's site to render their payment.

If your own site's programming is using login sessions, that doesn't affect the cart-tracking cookie we set in your browser. If you're using the same browser to test a theoretical Buyer A and Buyer B scenario, then your cart in that browser will always show the same contents for up to 24 hours, regardless of which user session you're logged into for the sake of your own site's programming.

You might try using two different browsers to "pose as" Buyer A and Buyer B for your own testing needs (say, use Firefox to pose as one buyer and IE/Safari/Google Chrome to pose as the other), which would simulate the effect of having separate buyers using our cart service in your site from their own computers independently.

Ok that answers my question. Basically, both e-junkie and paypal will not work for my needs. My customer will have several people using the same computer multiple times in the same day and they cannot see each others contents.

This would be a good feature to add. Basically, you should be able to send a user_id to the card that tells it which session to use if desired to accommodate this type of website.

Thanks for your help, I will use something else.

I often test my system by repeatidly logging on to several test user accounts (using the same PC) and I have never once experienced your issuses. sI'm using .NET rather than PHP. The fact that you experienced this problem before you came to e-junkie means that the problem is more likely to do with your coding rather than the cart
