title: Why is my Form POST taking me to a new page?
body: <p><strong>Setup</strong></p>
  
  <p>I have a simple HTML form that points to a PHP script that will send the email.</p>
  
  <p><strong>Problem</strong></p>
  
  <p>When I click submit the email is sent, but I am taken to the PHP url.</p>
  
  <p>I tried to all TARGET="_self" in the  and  declarations but i was still taken o a new page.</p>
