Error "mysqli_Num_Rows() "

[artslave]

Hello Larry,

On the coffee website, I got everything working and the database connection works, but when I click on the Wish LIst, add to cart or Cart button, I get the following error below. I wasn't sure if I have a setting wrong. I wasn't sure where to look at this point. Any direction would be helpful. Thank you in advance.

 

In case you need to see the following location of my files and URL:

// Determine location of files and the URL of the site:

define ('BASE_URI', '/Applications/MAMP/htdocs/ecommerce/');
define ('BASE_URL', 'http://localhost:8888/ecommerce/html/');
define('MYSQL', BASE_URI . 'mysql.inc.php');

 

 

 

An error occurred in script '/Applications/MAMP/htdocs/ecommerce/html/wishlist.php' on line 80:

That normally means your query is failing to return any records. I'd start by testing the query to see if it gives records or an error.
