U have to get all the session set stuff before in <head> cause when it reaches body, the header is sent and u cant change it.
call session start before your html codes. |

it's just like ,dnsi0, said. You cant modify a header after html is sent.
Allways start a session at the top of the page or before any html is sent.
Flushing the code might work too but even if it does it's not recomended.
