Cannot run php upload file code. MySQL/PHP

[denismm778]

This is my HTML code:

 

<form class="stdform" action="php/sp1img.php" method="post">




<p name="title">
<label>Image:</label>
<span class="field">
<input type="file" name="sponsupload1" />
</span>








<p class="stdformbutton"><button class="btn btn-primary">Save!</button></p>
</p></form>

And here is my PHP script called "sp1img.php" :

<?php
session_start();
$con = mysql_connect("localhost","***","***");
mysql_query("SET NAMES UTF8");
if (!$con)
 {
 die('Could not connect: ' . mysql_error());
 }
mysql_select_db("***", $con);


$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($extension, $allowedExts))
 {
 if ($_FILES["file"]["error"] > 0)
   {
   echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
   }
 else
   {
   echo "Upload: " . $_FILES["file"]["name"] . "<br>";
   echo "Type: " . $_FILES["file"]["type"] . "<br>";
   echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
   echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";


   if (file_exists("upload/" . $_FILES["file"]["name"]))
     {
     echo $_FILES["file"]["name"] . " already exists. ";
     }
   else
     {
     move_uploaded_file($_FILES["file"]["tmp_name"],
     "upload/" . $_FILES["file"]["name"]);
     $sql = mysql_query("TRUNCATE TABLE sp1img");
     $qry= "INSERT INTO `sp1img` (`ImgCode`) VALUES ('". www.dsaidov.com/velto/admin/upload/$_FILES["file"]["name"] ."')";


     header("location: ../sponsors.php");
     exit();
     }
   }
 }
else
 {
 echo "Invalid file";
 }


 mysql_close($con);
?>

And when I choose file and click Save! it is always giving me Invalid File!, I really can't understand what is wrong. I hope you can help me.
