Wordpress fb pagetab pass multiple app_data vars from url to app WordPress

• SOLVED

Hello, I need some help with my facebook page tab. It should be pretty straight forward in terms of the amount of code needed, but I'm not 100% sure whats necessary when it comes to facebook apps/tabs instance code.

Please see below what I have currently for my app instance, in my header.php



require 'facebook-php-sdk-98f2be1/src/facebook.php';

######### edit details ##########
$appId = '000000000000000'; //Facebook App ID
$appSecret = '000000000000000000000000000000'; // Facebook App Secret
$return_url = 'http://example.co.uk/script/process.php'; //return url (url to script)
$homeurl = 'http://example.co.uk/script/'; //return to home
$fbPermissions = 'publish_stream,manage_pages'; //Required facebook permissions
$canvasPage = "http://www.facebook.com/pages/example?sk=app_000000000000000";
##################################

//Call Facebook API
$facebook = new Facebook(array(
'appId' => $appId,
'secret' => $appSecret
));

$fbuser = $facebook->getUser();




So as you can see, I started my application instance above. As you can see there is no authentication yet, as I'm not sure if it will be needed.

OK heres the idea of what I need to do...

I need to simply get to wordpress pages within the page tab from the facebook page tab url.

My current facebook page tab iframe canvas points to...

<strong>http://www.example.co.uk/</strong>

and the facebook url is... <strong>http://www.facebook.com/pages/example?sk=app_000000000000000</strong>



So I would like to be able to navigate to...

<strong>http://www.example.co.uk/on-road</strong>

via... <strong>http://www.facebook.com/pages/example?sk=app_000000000000000&app_data=on-road</strong>



<em>I'm not sure if the best way to redirect is via a script echo'd before at the top of the page like this...</em>


if ( $appData = 'on-road' ) {
echo("<script> window.open.href='" . get_bloginfo('url') . "/on-road'</script>");
}


<em>but i'm open to other suggestions.</em>



This is where I get very lost... I also need to pass a second variable though, because I am running this script below in my theme...


autoBike = function () {
var bike = '<?=(isset($_REQUEST['bike']) ? htmlentities($_REQUEST['bike']) : null)?>',
$bike = $('#bike-main-slider div.bike[data-bike=' + bike + ']');
if ( $bike.size() > 0 ) {
var bikeIndex = $bike.index();
mainSlider.goToSlide(bikeIndex);
scrollTo(378);
}
};
autoBike();


the second variable would be <strong>?bike=450cc</strong> for example.



So maybe the facebook URL would look like this...

<strong>http://www.facebook.com/pages/example?sk=app_000000000000000&app_data={"page":"on-road","bike":"450cc"}</strong>


...which would some how output this within my page tab iframe...

<strong>http://www.example.co.uk/on-road/?bike=450cc</strong>



I hope this makes sense, please feel free to ask any questions.

Full prize amount will go to working PHP addition to my current app instance.



Many Thanks
Josh

Hi Josh,

Please check this code:
[[LINK href="http://pastebin.com/28qxV2KQ"]]http://pastebin.com/28qxV2KQ[[/LINK]]

for redirect you can both javascript or http-equiv="refresh",
you can uncommented <meta> refresh if you need to use it.

edit: syntax error, please check new pastebin link..

I use facebook signed_request object in case no signed_request data pass,
so need to include facebook class

Dbranes answers:

hi, have you tried to url-encode the value of the app_data variable, to get more than one variable through?

fx:

http://www.facebook.com/pages/example?sk=app_000000000000000&app_data=on-road%26bike%3D450cc

where

app_data=on-road&bike=450cc

is written as

app_data=on-road%26bike%3D450cc

where (%26 for &) and ( %3D for =)
