Recommended Posts



Theres something wrong with my code as I keep getting this error. It points to the bottom line of code. Can you tell me whats wrong with it please?


Thank you :)

$connection= mysqli_connect("$db_server","$db_username","$db_password", "$db_database") or die ("could not connect to mysql"); 
$sqlCommand = mysqli_query($connection,"SELECT * FROM client WHERE username='$myusername' and password='$mypassword'");

$count = mysqli_num_rows($connection,$sqlCommand);

Well it's a pretty straight forward error.  You're giving it 2 arguments and it only wants one, the result from the query itself.  So remove the $connection.
