如何在Facebook注册插件中设置字段？

Question

I have the facebook registration plugin on the site and I'm correctly parsing the signed request from facebook. However, I want to set the fields with the data I've just received when the page reloads so all the fields are not blank. How do I access these fields to set them? From reading the documentation, I noticed that there is a variable called 'form' that gets passed to a function if the onvalidate field is specified in the facebook registration plugin.

However, this is only effective on submit, not on page load so I can't really use that. Is there any other method of setting the registration fields?

Answer 1

Just use the PHP array function to request what you want pulled out of the info that gets sent. For example

if you want the users email it would be

$email = $response["registration"]["email"];

If you want custom fields then you'll need to read the documentation and add the custom fields into the &fields section of the registraton page. Don't forget to define them in your callback url though!

PS if you can answer my question now that'd be great ;) (http://stackoverflow.com/questions/9405647/facebook-registration-connect)
