title: Is URL parameters okay in HTTP POST requests?
body: <p>I'm working with some HTML forms and I just want to know if it is okay to use a URL parameters in the action attribute even if the method attribute is POST?</p>
  
  <pre><code>&lt;form action="index.php?somefield=someval" method="post"&gt;
      &lt;input name="anotherfield" value="anothervalue" type="text" /&gt;
      &lt;input type="submit" /&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>Well, this works fine, I can get all fields and their values in my postback page but I want to know if I'm breaking some rules, standard or something by doing this? Please, if you can, show some resource that can prove it is okay because I can't find it in W3.org.</p>
