k3n3t1k Posted November 14, 2007 Share Posted November 14, 2007 Could you look at this code and tell me what you think would cause the page not to foward to the header? <?php session_start(); ?> <html> <head> <title> Login </title> <body> <?php require_once "dbconfig.php"; $sql = mysql_query("SELECT * FROM studentcenter WHERE username='"($_POST['username'])."'") or die("Username is Incorrect ".mysql_error()); /* Check if Username Exists */ $results = mysql_fetch_array($sql) or die("Error at results section: ".mysql_error()); /* Puts database information into an array */ if($result['password'] == $_POST['password']) { /* Checks if passwords match */ /* Start Session */ header ("Cache-control: private"); $SESSION['sessionname'] = $_POST['username']; session_name($SESSION['sessionname); session_id([id]); echo("Welcome, Forwarding"); header("location: studenthome.php?id") or die("Will not foward" .mysql_error()); }else{ echo "Incorrect Login, please try again or <a href="register.php">Register</a>"; } ?> </body> </html> Thanks, k3n3t1k Link to comment https://forums.phpfreaks.com/topic/77366-help-me-with-a-header-plz/ Share on other sites More sharing options...

roopurt18 Posted November 14, 2007 Share Posted November 14, 2007 Well, first off you have a syntax error that darkfreaks fixed. Secondly, you're using the wrong variable for sessions; try $_SESSION instead of $SESSION. Thirdly, you are echo'ing output before your call to header(). You must never do this. Headers have to be sent before any output; nothing can come before headers, not even white space. You'll have to restructure your logic to fix that. Fourth, if you want to redirect with a header('Location: ...') then you must call exit(); afterwards or your script will keep processing.

k3n3t1k Posted November 14, 2007 Author Share Posted November 14, 2007 Is this what it should look like after those errors? <?php header ("Cache-control: private"); $_SESSION['sessionname'] = $_POST['username']; session_name($SESSION['sessionname']); session_id([id]); header("location: studenthome.php?id"); exit(); echo("Welcome, Forwarding"); or die("Will not foward" .mysql_error()); }else{ echo "Incorrect Login, please try again or <a href="register.php">Register</a>"; } ?> Link to comment https://forums.phpfreaks.com/topic/77366-help-me-with-a-header-plz/#findComment-391669 Share on other sites More sharing options...

k3n3t1k Posted November 14, 2007 Author Share Posted November 14, 2007 I tried the suggestions above to no avail. I probabbly should have posted this before but there is more code, here is the entire page: <?php session_start(); ?> <html> <head> <title> Login </title> <body> <?php require_once "dbconfig.php"; $sql = mysql_query("SELECT * FROM studentcenter WHERE username='"($_POST['username'])."'"); /* Check if Username Exists */ $results = mysql_fetch_array($sql); /* Puts database information into an array */ if($result['password'] == $_POST['password']) { /* Checks if passwords match */ /* Start Session */ header ("Cache-control: private"); $_SESSION['sessionname'] = $_POST['username']; session_name($_SESSION['sessionname']); session_id(1); header("location: studenthome.php?id=1"); exit(); }else{ echo "Incorrect Login, please try again or <a href="register.php">Register</a>"; } ?> </body> </html> Link to comment https://forums.phpfreaks.com/topic/77366-help-me-with-a-header-plz/#findComment-391702 Share on other sites More sharing options...
roopurt18 Posted November 14, 2007 Share Posted November 14, 2007 You are sending output before your calls to header(). <?php session_start(); ?> <html> <head> <title> Login </title> <body> That markup counts as output. I already told you that you need to restructure your code to avoid that.

k3n3t1k Posted November 14, 2007 Author Share Posted November 14, 2007 I put the both headers before anything. It still wont foward. <?php header("location: studenthome.php?id=1"); header ("Cache-control: private"); session_start(); require_once "dbconfig.php"; $sql = mysql_query("SELECT * FROM studentcenter WHERE username='"($_POST['username'])."'"); /* Check if Username Exists */ $results = mysql_fetch_array($sql); /* Puts database information into an array */ if($result['password'] = $_POST['password']) { /* Checks if passwords match */ /* Start Session */ $_SESSION['sessionname'] = $_POST['username']; session_name($_SESSION['sessionname']); session_id(1); /* header("location: studenthome.php?id=1"); */ exit(); }else{ echo "Incorrect Login, please try again or <a href="register.php">Register</a>"; } ?> Link to comment https://forums.phpfreaks.com/topic/77366-help-me-with-a-header-plz/#findComment-391733 Share on other sites More sharing options...
roopurt18 Posted November 14, 2007 Share Posted November 14, 2007 Try this: <?php header('Location: http://www.google.com/'); exit(); ?> Confirm that it works in the most simple case.
