my form just updates the site without results

[DubbelOseven]

Ok, I got a form, but when i submit the text nothing happends. Is there something wrong with my code?

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

<input type="text" name="link" size="70" >
<input type="submit" name="submit" value="submit">

</form>

I guess the code is right.

You need to echo the $_SERVER['PHP_SELF']

[DubbelOseven]

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

EDIT:
It didn't help :/
