wish helps you You'v forgotten to call mysql_query first. Also you missed quotes near $fbemail in select statement:
<?php
$checkdupe = mysql_query("SELECT Email from userregtable where Email='$fbemail'");
ALTER TABLE userregtable ADD UNIQUE (Email);
INSERT IGNORE INTO userregtable (Name, Email) VALUES ('$fbname', '$fbemail');
<?php

$checkdupe = mysql_query('SELECT Email from userregtable where Email="' . mysql_real_escape_string($fbemail) . '"');
mysql_query('
  INSERT INTO userregtable (Name, Email) 
  VALUES (
  "' . mysql_real_escape_string($fbname) . '", 
  "' . mysql_real_escape_string($fbemail) . '"
  )
');
<?php echo mysql_errno() . ": " . mysql_error() . "\n";

php json returning bool(false)

With these it helps I replicated your problem and I observe bool(false) when the ajax url is wrong (not found). Make sure your "someurl" is valid.
If the JSON is invalid, your script would still print it correctly. If the url returns nothing you's still observe 'string(0) ""'

Why is this returning bool(false)?

will be helpful for those in need To answer your question:
mysql_result returns FALSE on error. You are passing the array from mysql_fetch_assoc instead of the mysql resource as required by mysql_result's function signature:
string mysql_result ( resource $result , int $row [, mixed $field = 0 ] )
// Change
$movement_performed = mysql_fetch_assoc($query);
$return = result(mysql_result($movement_performed, 0) == 1) ? true : false;

// to
$movement_performed = mysql_fetch_row($query);
return $movement_performed[0] > 0;

wish of those help Is showQuizDialog(rightA) supposed to magically change the value of rightA? (I'm assuming you're not passing it by reference).
Did you mean to write rightA = showQuizDialog(rightA) or rightA = quiz -> askQuestion(rightA)?

will be helpful for those in need You need to check [CLLocationManager authorizationStatus], not locationServicesEnabled. Authorization status returns an app-specific value, one of the following:
typedef enum {
   kCLAuthorizationStatusNotDetermined = 0,
   kCLAuthorizationStatusRestricted,
   kCLAuthorizationStatusDenied,
   kCLAuthorizationStatusAuthorized
} CLAuthorizationStatus;

this will help , For the Sleep field you can use a pointer which can be also a nil:
type userAccount struct {
    Sleep *bool
}
func check(u userAccount) {
    if u.Sleep == nil {
        // not set
    } else if !(*u.Sleep) {
        // set to false
    } else {
        // set to true
    }
}
