i'm using this code to connect into my panel administration... for some reason there is no cookies set when i'm try to login... ( no cookies => no login ) when i debug the $_COOKIE it return an empty array !! this code work just fine in localhost and the stranger thing it work also in another web server, but not in this web server that i'm using actually... i can't understand where is the problem   ?! any suggestion are welcome

 

thank you

Maybe try 

setcookie( "name", "value", "future_timestamp", "path", "domain" );

 

I thought the path and domain was required.

Can you verify that the code is actually reaching "setcookie" and not being sent back to the index.php in the count check? IE The database query might be returning no results.
