Question

I know, that my question was asked a lot of times here, but for me no answer worked. I ve created a Facebook Fanpage Tab. All the files are stored at my private Webspace. Now I want to determine if a user already liked the page or haven t liked it yet!

So I used this code:

<?php
    function parsePageSignedRequest() {
        if (isset($_REQUEST[ signed_request ])) {
            $encoded_sig = null;
            $payload = null;
            list($encoded_sig, $payload) = explode( . , $_REQUEST[ signed_request ], 2);
            $sig = base64_decode(strtr($encoded_sig,  -_ ,  +/ ));
            $data = json_decode(base64_decode(strtr($payload,  -_ ,  +/ ), true));
            return $data;
        }
        return false;
    }

    if($signed_request == parsePageSignedRequest()) {
        if($signed_request->page->liked) {
            $isteinfan = "false";
        } 
        else {
            $isteinfan = "true";

        }
    }   
    //PHP Variable an JavaScript übergeben
    echo "<script>";
    echo "isteinfan =  $isteinfan ;";
    echo "console.log( ist ein fan:  );";
    echo "console.log(isteinfan);";
    echo "</script>";
?>

But it doesn t work. Can u give me help, please!!! Yours, Raphael

我将建议你列入www.inbook php图书馆,您可从以下网站下载:。你们必须将这三个档案放在同一个目录中。然后,可以找到<代码>如。地位非常容易:

define( APP_ID , xxxxxxxx );
define( APP_SECRET , xxxxxxxx );

require ("facebook.php");

$facebook = new Facebook(array(
     appId   => APP_ID,
     secret  => APP_SECRET,
     cookie  => true,
));

$signed_request = $facebook->getSignedRequest();

$liked = $signed_request["page"]["liked"];

如今,<代码>仿照是一种可以读到<条码>的ool。
