header() problem!!

[asherinho]

Hi! I have a login form and I want to direct two different types of users to a their respsective pages.here is the part of the codes

 

if(mysql_num_rows($result) > 0){

$logged_in_user=$uname;

$logged_in_pass=$pass;

session_register("logged_in_user");

session_register("logged_in_pass");

while($record=mysql_fetch_assoc($result)){

if($record["status"]=="administrator"){header( "Location: http://localhost/flis/iframe_admini.php" );exit;}

    elseif($record["status"]=="user"){header( "Location: http://localhost/flis/iframe_user.php" );exit;}

}

 

I get the following warning:

 

Warning: Cannot modify header information - headers already sent by (output started at C:\Program Files\xampp\htdocs\FLIS\login.php:12) in C:\Program Files\xampp\htdocs\FLIS\login.php on line 78

 

Help me,what should I do?

There is a sticky thread in the PHP Help board.

http://www.phpfreaks.com/forums/index.php/topic,37442.0.html

Put this at very top of the page after php tag.

ob_start();

Put this at very top of the page after php tag.

ob_start();

I wouldn't personally suggest this, as it isn't really "solving" the error.

Hey projactfear,I read the sticky but there is a problem still,I cant log in at all,it's as if the user name and password variables are not sent to the php page.here are the codes for the userlogin.php

 

 

<? session_start();

ob_start();

if (!isset($_POST['uname']) || !isset($_POST['pass'])) {

header( "Location: http://localhost/flis/index.html" );}

 

 

$uname=trim($uname);

$uname=$_POST['uname'];

$pass=$_POST['pass'];

$passwod=md5($pass);

 

      if($uname && $passwod){

 

if($logged_in_user==$uname && $logged_in_pass==$pass){

echo "<B style='color:red;font-size:15px'>YOU ARE ALREADY LOGGED IN!</B><BR>";

if($record["status"]=="administrator"){header("Location: http://localhost/flis/iframe_adm.php" );exit;}

elseif($record["status"]=="user"){header("Location: http://localhost/flis/iframe_usr.php" );exit;}

}

 

              require("connection.php");

$db=mysql_connect("$host","$user","$password");

mysql_select_db("$dbname",$db);

$result=mysql_query("select * from login where uname='".$uname."' and pass='".$passwod."'");

 

            if(!$result){echo "error in query";}

 

if(mysql_num_rows($result) > 0){

    $logged_in_user=$uname;

    $logged_in_pass=$pass;

    session_register("logged_in_user");

    session_register("logged_in_pass");

      while($record=mysql_fetch_assoc($result)){

        if($record["status"]=="administrator"){header("Location: http://localhost/flis/iframe_adm.php" );exit;}

elseif($record["status"]=="user"){header("Location: http://localhost/flis/iframe_usr.php" );exit;}

                                                                            }

        }

else{header("Location: http://localhost/flis/index2.html");exit;}

}

else{header("Location: http://localhost/flis/idex3.html.php" );exit;}

 

?>

 

What's wrong here                       

[JasonLewis]

I didn't read your code. Please wrap code in [ code ] tags or [ php ] tags.

 

Remember to place an ob_end_flush() at the end of the document if your insisting on using output buffering.

[Juan Dela Cruz]

f($logged_in_user==$uname && $logged_in_pass==$pass){
      echo "<B style='color:red;font-size:15px'>YOU ARE ALREADY LOGGED IN!</B><BR>";
      if($record["status"]=="administrator"){header("Location: http://localhost/flis/iframe_adm.php" );exit;}
             elseif($record["status"]=="user"){header("Location: http://localhost/flis/iframe_usr.php" );exit;}
                     }

 

maybe thats causing the error you are trying to output something then redirect

[asherinho]

Man,still is not workin,the same problem

 

<? session_start(); 
ob_start();
if (!isset($_POST['uname']) || !isset($_POST['pass'])) {
header( "Location: http://localhost/flis/index.html" );} 

              
     $uname=trim($uname);
     $uname=$_POST['uname'];
     $pass=$_POST['pass'];
     $passwod=md5($pass);
           
     if($uname && $passwod){
                
  if($logged_in_user==$uname && $logged_in_pass==$pass){
     if($record["status"]=="administrator"){header("Location: http://localhost/flis/iframe_adm.php" );exit;}
            elseif($record["status"]=="user"){header("Location: http://localhost/flis/iframe_usr.php" );exit;}
                    }
                       
             require("connection.php");
  $db=mysql_connect("$host","$user","$password");
  mysql_select_db("$dbname",$db);
  $result=mysql_query("select * from login where uname='".$uname."' and pass='".$passwod."'");
  
            if(!$result){echo "error in query";}
                    
  if(mysql_num_rows($result) > 0){
       $logged_in_user=$uname;
       $logged_in_pass=$pass;
       session_register("logged_in_user");
       session_register("logged_in_pass");
         while($record=mysql_fetch_assoc($result)){
           if($record["status"]=="administrator"){header("Location: http://localhost/flis/iframe_adm.php" );exit;}
     elseif($record["status"]=="user"){header("Location: http://localhost/flis/iframe_usr.php" );exit;}
                                                                            }
           }
     else{header("Location: http://localhost/flis/index2.html");exit;}                      
     }
     else{header("Location: http://localhost/flis/idex3.html.php" );exit;}

ob_end_flush();                   
?>

[Juan Dela Cruz]

are you sure you are not including this file somewhere ?

[JasonLewis]

That has got to be some darn messy code. Sorry.

[Juan Dela Cruz]

not sure but that maybe the reason of having this error?

 

if you do this

 

html here and stuff to be displayed

 

php here

 

i guess that will cause error

[asherinho]

I didnt include it anywhere.

 

What do u mean Projectfear?

 

I didnt exactly get u Juan

[JasonLewis]

I mean your code is very messy. One line if statements are ugly, and hard to read and could cause errors. I sifted through your coding, editing things and making it a bit tidier. Try this:

 

(Your also calling $record when it isn't even set, near the top... Why?)

 

<?php
ob_start();
session_start(); 
if(!isset($_POST['uname']) || !isset($_POST['pass'])){
header( "Location: http://localhost/flis/index.html" );
exit;
} 

  $username = trim($_POST['uname']);
$password = md5($_POST['pass']);
            
   if($username != "" && $password != ""){
                 
   if($_SESSION['logged_in_user'] == $username && $_SESSION['logged_in_pass'] == $password){
      if($record["status"]=="administrator"){
			header("Location: http://localhost/flis/iframe_adm.php" );
			exit;
		}elseif($record["status"]=="user"){
			header("Location: http://localhost/flis/iframe_usr.php" );exit;
		}
    }
                        
	require("connection.php");
	$db=mysql_connect($host,$user,$password);
	mysql_select_db($dbname,$db);

	$result = mysql_query("SELECT * FROM login WHERE uname='".$username."' AND pass='".$password."'");
   
	if(!mysql_result($result,0)){
		die("Error in query.");
	}
                     
  if(mysql_num_rows($result) > 0){
    $_SESSION['logged_in_username'] = $username;
	$_SESSION['logged_in_password'] = $password;

    $record = mysql_fetch_assoc($result);
    
	if($record["status"]=="administrator"){
		header("Location: http://localhost/flis/iframe_adm.php" );
		exit;
	}elseif($record["status"]=="user"){
		header("Location: http://localhost/flis/iframe_usr.php" );
		exit;
	}
  }
}else{
header("Location: http://localhost/flis/index2.html");
exit;
}

ob_end_flush();                   
?>

I tried the codes but it's not working.Nothing is been done,nothing is displayed but on the url on top of the browser it shows the url to the userlogin.php page

[samshel]

Generally header errors are caused when you print something before redirecting. Check if you have printed/echoed something purposely or by mistake.

 

Even a space or a newline at the end of included file after ?> tag can cause problems.

[asherinho]

can you pass through the code above posted by projectfear? and try to cross check to find any error
