[PHP4]: Problem with Form not putting Data in Post Request

Hi, I got a slight problem with a Form that doesn't correctly transmits its data correctly under entering some special data. I put together an example to get hold of the problem but so far I do not have a clue why this doesn't work. Be great if someone got an idea. Here is the sample script I put together to see what actually gets transferred when the Form is submitted. File: ftest.php <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>Form Test Page</title> <META http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <form action=ftest.php method='post' encoding='text/plain'> Enter a text: <input name=TheText type=text size=10 maxlength=10><input type=submit> </form> <?php import_request_variables("gPC","FORM"); echo "Data from last request:<br>"; echo "POST:<br>"; print_r ($_POST); echo "<br>GET:<br>"; print_r ($_GET); echo "<br>Cookies:<br>"; print_r ($_COOKIE); ?> </body> </html> Pretty simple and straightforward. The statistics page I currently work on requires to enter a Groupname. All but one groupname so far get accepted. The one that does not get accepted is <Group> including the "<>" If I enter this into the form and submit the data doesnt get forwarded into the post data. Even changing the encoding did not work. I tried >< that did work strange enough even <> alone works but as soon something is in between <> nothing gets into the post-data. Does anybody have an explanation? Maybe I overlooke something.
