Image upload form in PHP does nothing, no error

I have the following PHP code that I am using to upload an image to MySQL. When I click submit nothing happens.

include ("connect.php");
session_start();
$login = $_SESSION['wname'];

if((@$_POST['submit'])&&(isset($_FILES["myfile"]))){
  // properties of the uploaded file
  $name = $_FILES["myfile"]["name"];
  $type = $_FILES["myfile"]["type"];
  $size = $_FILES["myfile"]["size"];
  $temp = $_FILES["myfile"]["tmp_name"];
  $error = $_FILES["myfile"]["error"];

  if($name){
    die("Error uploading file! Code $error.");
  } else {
    $place = "avatars/$name";
    move_uploaded_file($tmp_name,$place);
    $query = mysql_query("UPDATE page SET pid_image_name = '$place' WHERE wname = '$login' ");
    die("upload complete <a href='index.php'>View imag开发者_Python百科e</a>");
    echo "Upload complete!";
  }
} else {
  die("select a file"); 
}

Here's my form:

<form action='up.php' method='POST' enctype='multipart/form'> 
<input type='file' name='myfile'>
<p> <input type='submit' name='submit' value="upload">

What am I doing wrong?

Another important parameter to check out in php.ini is post_max_size. If you set upload_max_filesize > post_max_size the result is that no data is written to $_POST nor $_FILES for files which sizes exceed post_max_size but are below upload_max_filesize

1. Format you're code.
2. Are you submitting the actual HTML form (not the PHP code) as html/multipart?? I am willing to be you're not. (enctype="multipart/form-data" needs added to your form tag!)
3. Learn to debug - actually put conditions elsewhere and see where your code is failing!

In your HTML for have you got enctype="multipart/form-data"?
Something like this:

<form action='submit.php' method='post' enctype="multipart/form-data">

Edit 1: if you do this:

if(move_uploaded_file($tmp_name, $place)){
   echo "did move file<br />";
}else{
   echo "move failed<br />";
}

You will get move failed (Or I do with your code)

Edit 2 I found your problem:
you misspelt the temp-dir variable: you defined $temp but in the move_uploaded_file you asked for $tmp_name so here the correct code:
move_uploaded_file($temp, $place);

Just in case you can't see any errors activate error reporting by setting error_reporting(E_ALL); right after the php tag.
