Warning: Cannot modify header information

[akkad]

hi everybody ; this is what i am getting when loading the page traffic.html , in the frame body.php:

 

Warning: Cannot modify header information - headers already sent by (output started at /opt/lampp/htdocs/xampp/thesis/admin/body.php:2) in /opt/lampp/htdocs/xampp/thesis/admin/body.php on line 64

Warning: Cannot modify header information - headers already sent by (output started at /opt/lampp/htdocs/xampp/thesis/admin/body.php:2) in /opt/lampp/htdocs/xampp/thesis/admin/body.php on line 68

 

though i am not ouputting anything before these lines .

<code>

if(($day == "- Day -") && ($month == "- Month -") && ($year != "- Year -"))

{

$date=$year;           

setcookie("day",$day); // line 64

                setcookie("month",$month); // 65

                setcookie("year",$year);//66

                setcookie("first_param", $first_param);//67

setcookie("second_param", $second_param);//68

 

echo shell_exec("cat `bash ./cal $date` | grep $first_param  | /usr/bin/perl  /opt/lampp/htdocs/xampp/thesis/calamaris/calamaris -a -P 60 -T 0 -r 400 -d 500 -u -O -F html");

 

}

</code>

 

and when i am printing the cookies:

<code>

print_r($_COOKIE);

</code>

it is outputing :

Array ( [phpSESSID] => 443d8ad87a1817c428b5ba4f86ffe92a )

 

i would like to mention that this page is called after authentication and using header function to call it in the auth.php page:

<code>

<?php

session_start();

error_reporting(E_ALL);

ini_set('display_errors', True);

 

#echo $_POST['security_code'];

$userid=$_POST['userid'];

#echo $userid;

$server="10.2.0.12";        //change to ip address of ldap server

$basedn="OU=EDU,DC=academic,DC=aua,DC=am";      //change to reflect the ou and domain that your users are in.

#$script=$_SERVER['SCRIPT_NAME'];

 

 

 

 

                if ( ($_SESSION['security_code'] == $_POST['security_code']) && (!empty($_SESSION['security_code'])) && (isset($userid)) && (isset($password)))

                {

                       

                $filter="CN=$userid";

                        #$filter="(&(|(!(displayname=Administrator*))(!(displayname=Admin*)))(cn=$username))";

                              //define an appropriate ldap search filter to find your users, and filter out accounts such as administrator(administrator should be renamed anyway!).

                        $dn = "CN=$userid";

                                if (!($connect = ldap_connect($server))) {

                                        exit(0);

                                }

                                if (!($bind = @ldap_bind($connect,"$dn,"."$basedn",$password)))

                                {

                                exit(0);

                                }

                               

                                  #echo" after second bind";

                $sr = ldap_search($connect, $basedn,$filter);

exit(0);

}

                #$fullname=$info[0]["displayname"][0];

        } else {

      header("Location:newlog.php");

        #die();

      # echo "oops!";

        }

When you have print statements that span multiple lines, such as:

 

#print "
User unknown";

 

you must comment out all of the associated lines...not just the line where the print command is.  You can fix it one of two ways....

 

#print "User unknown";

 

or

 

#print "
#User unknown";
