Hi All ! I am having some problem with the code below. Everytime I run it it gives me the following error: Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\practice.com\displayUserData.php:7) in C:\xampp\htdocs\practice.com\displayUserData.php on line 12 The source code of the page is as follows: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title> new document </title> </head> <body> <?php $textColor = $_POST["TextColor"]; $boldText = $_POST["boldText"]; $userComments = stripslashes($_POST['userComments']); if(isset($_POST["saveInfo"])) { setcookie("userData",$userComments,time()+60*60*24*30); } if(isset($_POST['boldText'])) { echo "<b>"; } echo "<font color='$textColor'>"; echo $userComments; echo "</font>"; if (isset($_POST["boldText"])) { echo "</b>"; } ?></body> </html> If I comment the setcookie() part, it works fine.. I looked up for some online help n most of them say I might have a whitespace near the line number mentioned in the warning message. But I don't find any.. Please help ! Did you know?
