title: HTML form with multiple action. 1 for PHP and another for an API
body: <p>Hi I have form that start like this:</p>
  
  <pre><code>&lt;form id="SignupForm" action="results.php" method="post" accept-charset="utf-8" class="form-vertical"&gt; 
  </code></pre>
  
  <p>The values entered within the form's section will need to be processed on the results.php.</p>
  
  <p>However I also need to pass the values of the fields within the form section into a 3rd party application via an API that goes like this:</p>
  
  <pre><code>&lt;form accept-charset="utf-8" action="https://thirdpartysite.com/apikey"
  method="post"&gt;
  </code></pre>
  
  <p>How can I do this? Thank in advance.</p>
