title: Form to an other hidden thing with PayPal
body: <p>Okay, maybe not good explained but I have this:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top"&gt;
  &lt;input type="hidden" name="cmd" value="_xclick"&gt;
  &lt;input type="hidden" name="business" value="&lt;?php echo $output['Private']; ?&gt;"&gt;
  &lt;input type="hidden" name="return" value="http://MYWEBSITE/index.php?code=succes&amp;bruh=&lt;?php echo $userid; ?&gt;&amp;money="&gt;
  &lt;input type="hidden" name="lc" value="US"&gt;
  &lt;input type="hidden" name="item_name" value="Topup"&gt;
  &lt;input type="hidden" name="currency_code" value="USD"&gt;
  &lt;input type="hidden" name="button_subtype" value="services"&gt;
  &lt;input type="hidden" name="no_note" value="0"&gt;
  &lt;input type="hidden" name="bn" value="PP-BuyNowBF:Buy%20Now%20Button.png:NonHostedGuest"&gt;
  &lt;table&gt;
  &lt;tbody&gt;&lt;tr&gt;&lt;td&gt;&lt;input type="hidden" name="on0" value="TopUp_amounth"&gt;How much?&lt;/td&gt;&lt;/tr&gt;&lt;tr&gt;&lt;td&gt;&lt;input type="text" name="amount" maxlength="200"&gt;$&lt;/td&gt;&lt;/tr&gt;
  &lt;/tbody&gt;&lt;/table&gt;
  &lt;input type="submit" value="Top Up" name="submit"&gt;
  &lt;img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1"&gt;
  &lt;/form&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Now I want a method to get what they insert the '<code>TopUp_amounth</code>' into the return url. The <code>TopUp_amount</code> people can choose by their own. But I want it go get in the return <code>url</code> to. How do I do this?</p>
