hi all..
i had this problem
when i click submit at a form..this things comesout
Warning: session_start(): Cannot send session cache limiter - headers already sent
but the data submitted available in db table.
whats the error actually???
fyi,this mini system have login..but for the form,i didn't set user need to login.
you'll get that warning when trying to call session_start after outputting content to the browser with something like echo or print, or if you have embedded PHP that calls a session_start following HTML content.
The reason your DB update still works is because the error is just a warning. Warnings do not halt the compiler, they just spit out the warning text and continue.
