Sounds like you're on a bad host, hearing all of the problems that you've had with PHP.

He wasn't insulting you, he was just making a point.

Also use this instead of !$_POST:

PHP Code:

empty( $_POST[ 'name' ] ) === false

also get rid of that enctype there is no need for it

PHP Code:

<?php if(isset($_POST['name'])){ echo("hi ".$_POST['name'].""); } else { echo (" <form method=\"post\" enctype=\"text/plain\" action=\"$_SERVER['PHP_SELF']\"> Name: <input type=\"text\" name=\"name\"> <br /> <input type=\"submit\" value=\"Submit\" name=\"submit\"> </form> "); ?>

Try that. Does it refresh now. And what do you mean the page refreshes? Like when you load it it refreshes? Or what...?

That is useless, horrible code.

Fine I will do it for you.

PHP Code:

<?php if( empty( $_POST[ 'name' ] ) === false ) { echo 'Hi, ' . $_POST[ 'name' ]; } else { echo <<<HTML <form action="" method="post"> Name: <input type="text" name="name" /> <br /> <input type="submit" value="Submit" name="submit" /> </form> HTML; } ?>

I have been trying to figure this out but I can't...

Why on earth does pressing the Submit button just clear the boxes/refresh the page? Could it be that I messed up the action="" value?

You do have method="post" in the <form> tag don't you?

No, I thought you didn't need it if it's on the same page. I've also tried echo '<form action="'.$HTTP_SERVER_VARS['PHP_SELF'].'"; and so on but same problem.
