6.4 Adding Products

First of all, go to the '06Demo', open the folder 'products' and load the productHX0001.php file on notepad++.
Now go to https://developer.paypal.com and log in
Now just go to https://www.sandbox.paypal.com/ and log in using your virtual seller username and password. Click on 'Merchant services' and then on the 'Buy Now Button'.

Fill the 'Buy Now' form with the exact same values that the productHX0001.php has

• Same Product (Item) Name
• Same Item ID Number (it its the filename of the product in this case : productHX0001)
• Same Price
• Same Currency

Please pay attention when you write these values! Make sure that you have button encryption to Yes. Figure fig:30 When you are sure that your values are correct just press the 'Add More options' button.

Your button code will be generated. Just press the 'Select All' button and copy that code. Figure fig:32
fig:32 Adding Products Step3

Paste the button code at the productHX0001.php file (in the $Product['ButtonLink'] attribute). Now your product file should look something like the listing "Product file productHX0001.php" The given button code as you can see is encrypted and this improves the security of our site (Remember that at the step 1 of the generation of the code we selected the encrypted method).

Attention: Sometimes the copied code contains the single quotation character please remove that symbol.
For instance at the PayPal image the alt attribute can have this sting :
Make payments with PayPal - it's fast, free and secure!
Remove the single quotation like done below :
Make payments with PayPal - it s fast, free and secure!
