[In Shopping Cart App. Error Message]

In the categories php I am getting the following error. I checked the syntax with the finished file and its correct.

 

( ! ) Fatal error: Call to a member function prepare() on a non-object in C:\wamp\www\source\phpcartoopmvc-empty-projectfiles\app\models\m_categories.php on line 35 Call Stack # Time Memory Function Location 1 0.0006 669736 {main}( ) ..\index.php:0 2 0.0039 727112 Categories->get_categories( ) ..\index.php:4

It is the same whether I pass a category or not. I think its not connecting to the database.

Connection script in the init.php

//Connect to database

$server = 'localhost';

$user = 'root';

$pass = '';

$db = 'ks_shop';

$Database = new mysqli($server, $user, $pass, $db);

Please help

[Icon Fonts]

Hi,

 

I cant figure out which letter will display which icon with the icon fonts. Is there a map of all the letters and corresponding icons.
