title: Trouble adding second reCAPTCHA. Have Contact Form 7 w/ reCAPTCHA
body: <p>I have a Wordpress site, that uses the Contact Form 7 plugin and the reCAPTCHA functionality that comes with that, and that works great. I just put that part in place, everything is automatic. But now I'm trying to add a reCAPTCHA to another form (on page form1.php) that isn't set up with Contact Form 7. This is on a PHP page that basically includes the Wordpress header and footer, but does its own thing in the middle. One key point is that the footer includes one of the forms from Contact Form 7, so it's on every page on the site.</p>
  
  <p>I followed <a href="https://developers.google.com/recaptcha/intro" rel="nofollow noreferrer">Google's instructions</a>, forgetting I had the footer form. Then I saw an error in Firebug <code>Error: ReCAPTCHA placeholder element must be empty</code></p>
  
  <p>That brought me to <a href="https://stackoverflow.com/questions/28513959/new-recaptcha-doesnt-work-twice-in-basically-the-same-page">this StackOverflow topic here</a>. The only answer there by user easy going says that they had the same error when they realized they had imported the library twice.</p>
  
  <p>Ok, that's what I did too I realized. So, I can remove the script inclusion of <a href="https://www.google.com/recaptcha/api.js" rel="nofollow noreferrer">https://www.google.com/recaptcha/api.js</a> in my code since it's already included by Contact Form 7 (I see it in the source). I noticed Google had instructions for rendering multiple widgets, I checked it out. But the problem is that the script include line specifies the onload callback function. Big problem. I can't change that because Contact Form 7 puts that in, and I can't make a callback function of the same name since it's already used. Of course I don't want to mess with anything that Contact Form 7 does. But as a result, I don't know how to get it to call my callback function in form1.php which is where my HTML element is specified to render the captcha.</p>
  
  <p>Do you see any way around this issue? Any help is greatly appreciated!</p>
