  • @jazparkyn do a bit of math on it, if there are 8 pans, use some logic such as

    if(pans>1){
    (pans-1 * 2.00)+3.50)
    }
    else{3.50}

    there are probably loads of easier and more complex ways to do it. this is just an example of SUDO code u could use.

    good luck

  • hi Adam, you are great!!!!!!!!!!!
    I found you last month during my php project.I first landed on part 9.My probems where solved and my love for php was boosted.

    Now on holiday I’ve just today completed part 20.I’m happy to say that every part worked upto part 19.But I’ve just still downloaded the zip and will then work on the ipn script home work.

    many thanks

  • Your Videos really helped me to understand how it all comes together. One issue though even though I don’t think you will respond to it. I am placing the right email in the open area’s for the email that you provided. Paypal is saying it is not the right email…..I have tried various different ways of righting it but none seem to work. Am I missing something or is your IPN script broken? can anyone help me with this minor error?

  • This is so great, thanks so much for posting this. Would you say this method is just as secure as using ecommerce apps such as opencart, magento… ?

  • @TiagoMaggioniRs
    I have the same problem. I went as far as totally copy/paste Adam’s code and only changing mysql location and the 3 variables to pull the correct information for my mysql. The cart page renders perfectly but like you, when there are multiple items in the cart, changing the quantity of the last item added works perfectly. However, when trying to change the quantity of an earlier item, it seems like the server gets stuck before getting an error.
    How do we fix this?

  • terrific tutorials dude! i just cant download package… tells me the file is missing, can i download it from any other source?

  • i can’t seem to properly return to my website when buyer finish transaction, but thanks for this very well done tutorial though 🙂

  • I have problem with PayPal checkout, it goes on paypal page and displays: “You have requested an outdated version of PayPal. This error often results from the use of bookmarks.”

    Help? 🙂

  • I don’t know if you have an existing tutorial or not but I was wondering if you could teach how to implement listings from another site onto a personal site.

  • For example, I have a shop made on etsy.com and I also have my personal website. Rather than doing the work twice by posting items on both websites, I want to post it on etsy but show up on my website too.

  • Thanks for this amazing tutorial. I have been looking for something like for months. One thing though, how can I bypass the product page and the cart when and only get the card when the user is ready to check out. I have simple products and users doesn’t really need to access the product detail page because everything they need to know about the product is already on the list of products pages.
    Thank you for your help.

  • How could I have multiple stores within this application? the stores can simply considered as categories attached to the product so at the beginning users will have to use from what store they wanna by products to choose the closest to their location based on store name and address.

  • Wow! Finally, a working ipn. Thank you, thank you!, I’ve wasted so much time until I find your tutorial!
    How can I repay you, seriously..
    😀
