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.
