If you used functional coding you need add global var in your function

Fo example:

$DataBase = mysqli_connect("localhost", "test", "illusions", "test");

function test()
{
global $Database;
}

 

It's hard to help with your problem without code.

You need check $dbc, - it's must be MySQL resource id but not null

 

Maybe due to extra semicolon after 1

 

Post code for Link => $dbc

i think the Prob. is in your $dbc variable check it again or Post Code

 

For sure you missed to define $dbc before you execute the actual query.
