Uploading an image using PHP

Can someone look at the following code and let me know why it doesn't upload the image:

(there is no error when doing this but just doesn't work?

echo "<center><table cellspacing=\"3\" cellpadding=\"3\" border=\"0\">\n";
    echo "<form method=\"post\" action=\"addhome.php\" enctype = \"multipart/form-data\">\n";
    echo "<tr><td>Rendering Image:</td><td><input type=\"file\" name=\"rendering\" /></td><td></td></tr>\n";
    echo "<tr><td colspan=\"3\" align=\"right\"><input type=\"submit\" name=\"submithome\" value=\"Add Item\"></td></tr>\n";
    echo "</form></table></center>\n";


if(isset($_POST['submithome']))
{
//UPLOAD PICTURE
$filename = strtolower($_POST['rendering']);
move_uploaded_file($_POST['rendering'], $_SERVER['DOCUMENT_ROOT']."/homes/".$filename);
//END UPLOAD PICTURE
}

Code (markup):

 

Try:

echo "<center><table cellspacing=\"3\" cellpadding=\"3\" border=\"0\">\n";
    echo "<form method=\"post\" action=\"addhome.php\" enctype = \"multipart/form-data\">\n";
    echo "<tr><td>Rendering Image:</td><td><input type=\"file\" name=\"rendering\" /></td><td></td></tr>\n";
    echo "<tr><td colspan=\"3\" align=\"right\"><input type=\"submit\" name=\"submithome\" value=\"Add Item\"></td></tr>\n";
    echo "</form></table></center>\n";


 if(!empty($_FILES["rendering"])) 
{
//UPLOAD PICTURE
$filename = strtolower($_POST['rendering']['name']);
move_uploaded_file($_POST['rendering']['tmp_name'], $_SERVER['DOCUMENT_ROOT']."/homes/".$filename);
//END UPLOAD PICTURE
}

PHP:

 

echo "<center><table cellspacing=\"3\" cellpadding=\"3\" border=\"0\">\n";
    echo "<form method=\"post\" action=\"addhome.php\" enctype = \"multipart/form-data\">\n";
    echo "<tr><td>Rendering Image:</td><td><input type=\"file\" name=\"rendering\" /></td><td></td></tr>\n";
    echo "<tr><td colspan=\"3\" align=\"right\"><input type=\"submit\" name=\"submithome\" value=\"Add Item\"></td></tr>\n";
    echo "</form></table></center>\n";


if(isset($_POST['submithome']))
{
//UPLOAD PICTURE
$filename = strtolower($_FILES['rendering']['name']);
move_uploaded_file($_FILES['rendering']['tmp_name'], $_SERVER['DOCUMENT_ROOT']."/homes/".$filename);
//END UPLOAD PICTURE
}
