You just need to change line no. 168 to
<form enctype="multipart/form-data" action="" method="post">

hey guys I tried your solutions but they didn't work.
the problem was that I had to enter the recid to stay on the current view. this is what I did
<form enctype="multipart/form-data" action="test.php?a=edit&recid=<?php echo $recid; ?>" method="post">
that worked. However now I want to add an anchore to it so the page stays at same place... anyone know how to do that?
Thanks

You can append a named anchor to the end of your URL

so,

<form enctype="multipart/form-data" action="test.php?a=edit&recid=<?php echo $recid; ?>#anchor"method="post">
should do the trick.

<form action="<?php echo $_SERVER[PHP_SELF];?>" method="post">
