Issue with file upload PHP - php

Question

I am not sure what is wrong with this code, so I was hoping for some helpful input.
The Problem
It will not get the name of the file that I have uploaded nor is it actually uploading it into the defined directory.
The PHP Code
<? include("header.php");
include("sidebar.php");
?>
<h2>Add Raffle</h2>
<?
$name = asql($_POST['name']);
$type = asql($_POST['prize']);
$min_points = asql($_POST['minp']);
$min_cash = asql($_POST['maxu']);
$cons = strtotime($_POST['cons']);
$cone = strtotime($_POST['cone']);
if($_POST['subm'])
{
if ($name == NULL OR $type == NULL OR $min_points == NULL OR $min_cash == NULL) {
print"Please Fill Out All Of The Required Fields<br /><a href='rafadd.php'><img src='img/green_arrow_left.png' alt='Go Back' /></a>"; include"footer.php";
exit();
}
if (!in_array($file['type'], array("image/gif", "image/jpeg", "image/png"))
|| $file['size'] > 20000)
{
if ($_FILES["file"]["error"] > 0)
{
echo "There was an error";
}
else
{
echo "";
$filename = $_FILES["file"]["name"];
if (file_exists("../images/rewards/" . $_FILES["file"]["name"]))
{
unlink("../images/raffles/" . $_FILES["file"]["name"]);
move_uploaded_file($_FILES["file"]["tmp_name"],
"../images/raffles/" . $_FILES["file"]["name"]);
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"../images/raffles/" . $_FILES["file"]["name"]);
}
}
}
else
{
echo "Invalid file";
$updatecontests = mysql_query("INSERT INTO raffles (`id`, `raffle_name`, `raffle_prize`, `buy_in`, `max_entry`, `prize_image`, `start`, `end`) VALUES ('','$name','$type','$min_points','$min_cash','images/raffles/".$filename."','$cons','$cone')") or die(mysql_error());
if($updatecontests){
$create = mysql_query("CREATE TABLE IF NOT EXISTS `".$name."` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` text NOT NULL,
`entries` int(11) NOT NULL,
PRIMARY KEY (`username`(30)),
KEY `id` (`id`)
)");
}
print "You Have Successfully Added this Raffle<br /><br />
<a href='rafadd.php'><img src='img/green_arrow_left.png' alt='Go Back' /></a>";
}
else

I have used the file upload snippet in another script and it uploads perfectly so I am not sure why it is not working here.

Answer 1

in the form tag add enctype="multipart/form-data"
<form action='' method='post'enctype="multipart/form-data">

Answer 2

<form action='' method='post'>
is wrong, needs to be:
<form action='' method='post' enctype='multipart/form-data'>
Also, use <?php instead of <?
PS I miss the point where $file is set.

Answer 3

It doesn't look like file is being instantiated anywhere. Did you mean:
if (!in_array($_FILES['file']['type'], array("image/gif", "image/jpeg", "image/png"))
|| $_FILES['file']['size'] > 20000)
