Question

Working with the Facebook PHP SDK. I have the same .php tag in two different files, in one it works but in the other it returns nothing. Any idea? I have the same config.php file included in both.

include("config.php");
include("fbconnect.php");

if (!isset($_SESSION['user']))
{
    $valor_voto = mysql_query("select voto from $mes_id where email=$email");
    $row = mysql_fetch_array($valor_voto);
    $valor = $row['voto'];

    if ($valor == 1)
    {
        echo '<img class="icon" src="/images/greencheck.png">';
    }
    else
    {
        echo '<img class="icon" src="/images/check.png">';
    }
}
else
{
    echo '<img class="icon" src="/images/check.png">';
}

Looks to me that $email is what fails because if I input the email manually it will return any of the 2 spectated values.

Thanks for the time.

$email comes from fbconnect.php:

if ($user)
{
    try
    {
        // Proceed knowing you have a logged in user who's authenticated.
        $user_profile = $facebook->api('/me');

        //Connecting to the database. You would need to make the required changes in the common.php file
        //In the common.php file you would need to add your Hostname, username, password and database name!
        mysqlc();

        $name     = GetSQLValueString($user_profile['name'], "text");
        $email    = GetSQLValueString($user_profile['email'], "text");
        $gender   = GetSQLValueString($user_profile['gender'], "text");
        $bio      = GetSQLValueString($user_profile['bio'], "text");
        $hometown = GetSQLValueString($user_hometown['hometown'], "text");
        $query    = sprintf("SELECT * FROM newmember WHERE email = %s", $email);
        $res      = mysql_query($query) or die('Query failed: ' . mysql_error() . "<br/>\n$sql");

        if ( mysql_num_rows($res) == 0 )
        {
            $iquery = sprintf("INSERT INTO newmember values('',%s,%s,%s,%s,'yes',%s)", $name, $email, $gender, $bio, $hometown);
            $ires   = mysql_query($iquery) or die('Query failed: ' . mysql_error() . "<br/>\n$sql");

            $_SESSION['user'] = $user_profile['email'];
            $_SESSION['id'] = $user_profile['id'];

        }
        else
        {
            $row = mysql_fetch_array($res);
            $_SESSION['user'] = $row['email'];
            $_SESSION['id'] = $user_profile['id'];
        }
    }
    catch (FacebookApiException $e)
    {
        error_log($e);
        $user = NULL;
    }
}

Answer 1

Solved, i had the condition

if(!isset($_SESSION['user']))

but i wasn’t giving the condition

if(isset($_SESSION['user']))

so i wasn’t able to retrive any info.

Thanks for the time.
