you are actually looking for _GET['message3']
variable..
do something like that
$message = _GET['message3'] ;
if(isset($message){
$sql = insert your $message variable in database here
run the query
}
etc..
and you are done
I assume that you are learning over your localhost and you got the file Sent.jsp
solved How do I store the data which is passed though the browser link in a mySQL database? [closed]
