title: Refresh Form page after submitting the form?
body: <p>I use <code>target="_blank"</code> for my form submission to open the resulting page in new window but the previous or form page is still open and holding the values filled for form submission . If i click submit again it submits again with same values, so how would i refresh form page after submission.</p>
  
  <pre><code>&lt;form target="_blank" id="monthly_form" method="post" action="&lt;?php echo base_url().'billing/monthly_slip'; ?&gt;"&gt;
  ..form fields
  ...
  &lt;/form&gt;
  </code></pre>
