Custom Facebook Tab and Form Validator Php

Discussion in 'Facebook API' started by JhonBau, Jul 30, 2013.

    Hope you're good!
    Having troubles using a Facebook Custom Tab. I want to create a Tab that display a form for people who like the page and an image for people doesn't like the page.
    That works perfectly. But when pushing the SEND button, I got a blank page. I read herehttp://www.hyperarts.com/blog/getting-facebook-to-load-php-validation-errors-on-a-sign-up-form/ that I had to use this:
    With the condition:
    if (($like_status) || isset($_SESSION['form'])) {
    echo "<!-- fan-gated content -->";
    else {
    echo "<!-- non-fan content -->";
    The errors (echo) works and writing in the DB works well too but ANYONE can see the form. Even if they do not like the page.
    If anyone can help me please let me know. I'll be super happy!
    Here is the code:
    // Parametres mySQL
    $sql_serveur = "localhost"; // Serveur mySQL
    $sql_base = "xxxxxx"; // Base de donnees mySQL
    $sql_login = "xxxxxxxxx"; // Login de connection a mySQL
    $sql_password = "xxxxxxxxxx"; // Mot de passe pour mySQL
    // Connection au serveur mySQL
    @mysql_connect($sql_serveur, $sql_login, $sql_password) or die("Error connecting to the server");
    mysql_query("SET NAMES 'utf8'");

    I Also tried this:
    require 'facebook.php';
    $app_id = "MY APP ID";
    $app_secret = "MY APP SECRET";
    $facebook = new Facebook(array(
    'appId' => $app_id,
    'secret' => $app_secret,
    'cookie' => true
    $signed_request = $facebook->getSignedRequest();
    $page_id = $signed_request["page"]["id"];
    $page_admin = $signed_request["page"]["admin"];
    $like_status = $signed_request["page"]["liked"];
    $country = $signed_request["user"]["country"];
    $locale = $signed_request["user"]["locale"];
    if (($like_status) || isset($_SESSION['form'])) {
    echo "You like us";
    else {
    echo "You don't like us yet";

    But I always see: "You like us"

    Many Thanks Guys !
