  • They can enter their PayPal credentials.
  • Or they can choose to pay with debit or credit card if they don’t have a PayPal account. (Note: You need a Business PayPal account to allow your customers to pay with a credit card. A standard PayPal account will not display this option.)

PayPal Smart Checkout

Step 6 ) WordPress Simple Shopping Cart plugin now allows you to set up PayPal Smart Checkout payment. Click the following link enabling-smart-button-checkout-setup-and-configuration to learn more.

Note: When using “Smart checkout” PayPal bypasses the profile based tax and shipping. So it doesn’t work the same way as the standard PayPal checkout (in terms of profile based tax and shipping). That’s how the Smart checkout flow of PayPal works. If you need to use the profile based tax and shipping, you cannot use the PayPal smart checkout option unfortunately. Click the following link forum post to learn more.

Compact Shopping Cart

Step 7 ) Sometimes you may want to display a compact shopping cart on your sidebar or in a post. This allows the users to see that they have items in the cart and they can click a view cart button to go to the full shopping cart page. Click the following link compact shopping cart to learn more.

Troubleshooting Cart Orders

Q1 When I add a 2nd item to the cart it just replaces the first item instead of showing both items. How do I fix this issue?

Solution: This usually happens for one of the following reasons.

#1) The PHP Session on the site is not working (PHP session is not
setup correctly by the hosting provider). The following documentation php-session-not-working-correctly can help you.

#2) The site has some kind of caching somewhere so it is showing the
cached page (which doesn’t contain the cart).

Check the following forum post for more information.

============

Q2 The cart only works when I log in. When I visit the shopping cart page nothing shows up and or the cart does  not work. Why is that?

Solution: This usually happens when you have a cache plugin and your cart page is not excluded from getting cached. Check the following forum post for more information.

============

Q3 The plugin is not working for me. When I click on the Add to Cart button I get a fatal error message. How can I fix this issue?

Solution: This usually happens when you have added some special characters to the name=””
parameter in the shortcode. If this is the case, make sure you enable the following feature Disable Price Check for Add to Cart. This is located under General Settings tab. Check the following forum post for more information.

================================

I will be updating this post from time to time. So keep coming back for more.

Enjoy.
