title: PHP won't echo out the $_POST
body: <p>got a small problem, this code</p>
  
  <pre><code>&lt;form action="&lt;?php echo $_SERVER['PHP_SELF']; ?&gt;" method="post"&gt;
  &lt;?php
  ...
  echo '&lt;input name="textfield" type="text" id="textfield" value="Roger" /&gt;';
  echo 'Hello, '.$_POST['textfield'].'&lt;br&gt;';
  ...
  ?&gt;&lt;/p&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>should echo out "Hello, Roger", as roger is the default value, yet it gives out only "Hello, " and nothing else. Any suggestions?</p>
  
  <p>edit: yes, there's a form.</p>
  
  <p>Thanks!</p>
