help with page redirection

[gammaman]

When a user tries to access this page without logging in, it successfully sends redirects them back to the login.

 

<?php

   session_start();

   if($_SESSION['allowed']!=1){
      
         header('location:studentlog.php');
        
   }

$Conn=mysql_connect("localhost","fierm","13183");

if(!$Conn){
   echo "failed";
  }
  else{
  
mysql_select_db("fierm");

   
    
   
  echo "<a href=\"addCourse.php\">Add Courses</a>";
  echo "<br />";
  echo "<a href=\"addStudent.php\">Add Student</a>";
  echo "<br />";
  echo "<a href=\"addGrades.php\">Input Grades</a>";
}






?>

When I try to do the same thing on this page, it does not redirect and gives the user access.

<?php
   session_start();

   if($_SESSION['allowed']!=1){
      
         header('location:studentlog.php');
        
   }

  

   $Conn=mysql_connect("localhost","fierm","13183");
if(!$Conn){
   echo "failed";
  }
   else{
     
   mysql_select_db("fierm");
   
      echo "<table border=\"1\">";
      echo "<b>Registered Courses</b>";
      echo "<tr><th>CourseID</th><th>CourseName</th><th>Grade</th></tr>";
    
      $result1=mysql_query("select CourseID,CourseName,StudentID,Grade FROM Rcourse WHERE StudentID='{$_SESSION['user']}'");
      $cou=mysql_num_rows($result1);
    
      while($row=mysql_fetch_array($result1))
      {
      
       echo "<tr><td>$row[0]</td><td>$row[1]</td><td>$row[3]</td></tr>\n";
      }
     
     echo "</table>";

     
     echo "<b>Register For Courses:</b>";
     echo "<br />";
     echo "<a href=\"regCourse.php\">Register Courses</a>";
     echo "<br/>";
     echo "<b>Drop a Course</b>";
     echo "<br/>";
     echo "<a href=\"dropCourse.php\">Drop a Course</a>";


     
    }

?>

It seems to work now and the only thing I changed in the file was the deletion of two blank lines at the top of the file, Is that even possible.

It all depends on the software you are editing with!

 

Some software will insert a carridge return instead of a blank line, the problem with this is that NOTHING should be sent before the header even if it is junk!

 

I'm fairly sure thats right but I'll wait a while and see if I get corrected. 

Hope that helps.

Try this:

 

   if($_SESSION['allowed']!=1){
      
         header('location:studentlog.php');
        exit;
   }
