how to exist within the context?

[Bing Du <du_bing@xxxxxxxxxxx>]

Hi,

One webpage has its banner, left menu and footer ect that are controled 
by the template.  I want this php script to output the form and 
processing result within the page structure.  Without exit, if the 
'yourname' field is empty, the script would output 'Please enter your 
name!' fine within the page structure (that is, banner, menu and footer 
are all there).  But obviously the script does not terminate as it's 
supposed to.  With exit, the script terminates fine, but it outputs the 
result in a page without banner, menu and footer.  So what's the correct 
way to get the script stop and output its results always in the page 
structure.

<form method=post>
<input name="yourname" type="text" size="20">
<input name="submit" type="submit" value="submit">
</form>

<?php

$submit = $_POST['submit'];
$name = $_POST['yourname'];

if ($submit)
{
   if ($name=="")
  {
    print "Please enter your name!";
    //exit;
  }
}

echo "Continue processing...";
?>

Thanks in advance,

Bing
