lonelym 0 Report post Posted June 12, 2007 I haven't really read much about sessions, i usually study PHP by viewing other's codes and learning from it. Here's what keeps on popping out when I open the page. Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Program Files\xampp\htdocs\maple-radio-live\loggingin.php:7) in C:\Program Files\xampp\htdocs\maple-radio-live\loggingin.php on line 40 andWarning: Cannot modify header information - headers already sent by (output started at C:\Program Files\xampp\htdocs\maple-radio-live\loggingin.php:7) in C:\Program Files\xampp\htdocs\maple-radio-live\loggingin.php on line 55 Here is the sourcecode for the page:<?PHP include("config.php"); ?><HTML><HEAD><TITLE>Logging In<TITLE></HEAD><body bgcolor="black" link="#90ee90" alink="#90ee90" vlink="#90ee90"><?PHP// retrieve the submitted values$username1 = $_POST["username"];$password1 = $_POST["password"];$rememberMe = $_POST["rememberMe"];// make sure that rememberMe has a valueif ($rememberMe == "rememberMe"){ $rememberMe = "1";}else{ $rememberMe = "0";}//Starts the fontsprint $fs;//Checks if the username field was written onif ($username1 == ""){die("You did not write anything on the username field.");}if ($password1 == ""){die("You did not write anything on the password field.");}// check it the username exist$query = "Select * from usertable where username='$username1'";$result = mysql_query($query); if ($result != true){ die ("You have written an unregistered username."); } $row = mysql_fetch_assoc($result); if ($row["numloginfail"] >= 5){ die("You have logged in for more than 5 incorrect times.

I have written its values in config.phpThanks for the help. Share this post Link to post Share on other sites
TavoxPeru 0 Report post Posted June 12, 2007 You can't send any data before the Header function, unless you use output buffering, and in your code you are printing the $f and $fe variables by using the print() function, also if you use sessions you must start it before any other thing, so move your session_start() function to the very top of your page.Also, after your Header() function remove any whitespace like linebreaks or even spaces, is a good practice to include a call to the exit() function after the header() function.Why do you print your $f and $fe variables??? you can achieve the same result by simply adding it to your die() function calls, like: if ($username1 == ""){die($f."You did not write anything on the username field.".$fe);}or simply don't use them, and, yes, i know if you use it your code will be a bit bigger Best regards, Share this post Link to post Share on other sites
lonelym 0 Report post Posted June 13, 2007 Why do you print your $f and $fe variables?I print them out before and after the PHP script so that I wouldn't have to type them again and again. It works, so I don't really have any troubles with it.Thanks for replying. I understood how to do it now. Share this post Link to post Share on other sites
