I am getting this problem whenever I login from index.php to admin_area.php. I am giving the codes of the two files. Please help.

Index.php

php Syntax (Toggle Plain Text) 
  1. <?php
  2. 	session_start();
  3. 	include("../lib/globals.php");
  4.  
  5.  
  6.  
  7. 	if(isset($_REQUEST['submit']))
  8. 	{
  9. 		$u_name=$_REQUEST['username'];
  10. 		$pass=$_REQUEST['password'];
  11. 		$sql="select * from `user_table_master` where `user_name`='$u_name' and `password`='$pass'";
  12.  
  13. 		$result=mysql_query($sql);
  14. 		$row=mysql_fetch_array($result);
  15.  
  16. 		$num_of_rows=mysql_num_rows($result);
  17.  
  18. 		if($num_of_rows>0)
  19. 		{
  20. 			$_SESSION['logged_in']='y';
  21. 			$_SESSION['user_type']=$row['user_type'];
  22. 			$_SESSION['user_formation']=$row['formation'];
  23. 			$_SESSION['user_name']=$row['user_name'];
  24. 			$_SESSION['name']=$row['name'];
  25. 			$_SESSION['user_id']=$row['user_id'];
  26. 			$_SESSION['can_see_remarks']=$row['can_see_remarks'];
  27. ?>

Make sure there are no characters in the file before the <?php and save any UTF-8 files without the BOM.

Be sure that session_start(); is the first line in each of your codes without spaces or blank lines.

Thank You Very Much. There was a space before the <?php tag.

It solved my problem. Thanks
