title: Send email to address from form input
body: <p>I have a pretty standard contact form with inputs for name, email address and phone number. As well as sending the email to the specified email address as per a standard form,</p>
  
  <pre><code>$to      = 'diysoakwells@hotmail.com';
  </code></pre>
  
  <p>I would also like to send the email to the user using the address from the email address input from the form. I was thinking using the post variable from the email input like this would work:</p>
  
  <pre><code>$to      = 'diysoakwells@hotmail.com', $email;
  </code></pre>
  
  <p>but no luck. Can someone point me in the right directiona and are there any security risks in using this approach? I ultimately aim to provide the user with a checkbox that if checked sends a copy of the email to themselves.</p>
  
  <p>Here is a link to my form</p>

  <p>Thankyou in advance : )</p>
