html radio button not POSTing - php

Question

I am using a form with radio buttons to post a value to PHP. However, the value is not being sent. This is my code:
HTML:
<form action="voteupdate.php" id="form-id" method="post"onclick="document.getElementById(\'form-id\').submit();">
<input type="hidden" name="type" id="type" value="' . $type . '">
<input type="hidden" name="id" id="id" value="' . $id . '">
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-default '.$vup.'">
<input type="radio" name="vote" id="1" value="1">
<span class="glyphicon glyphicon-chevron-up"></span> Vote up
</label>
<label class="btn btn-default '.$vd.'">
<input type="radio" name="vote" id="2" value="2">
<span class="glyphicon glyphicon-chevron-down"></span> Vote down
</label>
</div>
</form>
PHP:
<?php session_start();
include('config.php');
$type = $_POST['type'];
$id = $_POST['id'];
echo $_POST['vote'];
if ($type == "images"){
$tid = "imgid";
}
if ($type == "pages"){
$tid = "pageid";
}
if ($type == "posts"){
$tid = "postid";
}
$table = str_replace(""," ",$type);
$table = str_replace('"'," ",$table);
$table = str_replace("'"," ",$table);
$stmt= $pdo->prepare("SELECT * FROM '".$table."' WHERE ".$tid." = :imgid");
$stmt->execute(array(':imgid' => $id));
$stmt = $stmt->fetch();
$vreg = explode(",", $stmt['votereg']);
foreach ($vreg as $v) {
$temp = explode("-", $v);
if ($_SESSION['uid'] == $temp['0']){
if (1 == $temp['1']){
header( 'Location: votesys.php' ) ;
}
else
{
$instruction = "update-exists";
}
}
}
echo $instruction;
?>

<form action="voteupdate.php" id="form-id" method="post"onclick="document.getElementById(\'form-id\').submit();">
is missing a space between method and onclick attributes:
<form action="voteupdate.php" id="form-id" method="post" onclick="document.getElementById(\'form-id\').submit();">
