Form upload image to simple modify

i have the upload image it works fine uploading the image sends the image path to databse and copy the image to the images folder. but now i trying to just modify the problem is the image path goes to the database but now the image is no longer copied, or replaced with into the images folder do i need to chenge the copy image on the script with something else

here the upload image code

$con = mysql_connect(“localhost”,“root”,“”);
if (!$con)
die('Could not connect: ’ . mysql_error());

mysql_select_db(“admin”, $con);


//echo ‘<br>’;

//define a maxim size for the uploaded images in Kb
define (“MAX_SIZE”,“100”);
//This function reads the extension of the file. It is used to determine if the file is an image by checking the extension.

function getExtension($str) {
$i = strrpos($str,“.”);
if (!$i) { return “”; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
//This variable is used as a flag. The value is initialized with 0 (meaning no error found) and it will be changed to 1 if an errro occures. If the error occures the file will not be uploaded.
//checks if the form has been submitted
//reads the name of the file the user submitted for uploading
//if it is not empty
if (strlen($image) >= 1) //////////////////////////////////////////////////////// CHANGED
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES[‘image’][‘name’]);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and will not upload the file, otherwize we will do more tests
if (($extension != “jpg”) && ($extension != “jpeg”) && ($extension != “png”) && ($extension != “gif”))
//print error message
echo ‘<h1>Unknown extension!</h1>’;
//get the size of the image in bytes
//$_FILES[‘image’][‘tmp_name’] is the temporary filename of the file in which the uploaded file was stored on the server
//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*102400)
echo ‘<h1>You have exceeded the size limit!</h1>’;
//we will give an unique name, for example the time in unix time format
$image_name=time(). ‘.’.$extension;
//the new name will be containing the full path where will be stored (images folder)

        $query="INSERT INTO photos values ('$image','$user')"; //into database
        mysql_query( $query );

        $copied = copy($_FILES['image']['tmp_name'], $newname);

        if (!$copied)
            echo '&lt;h1&gt;Copy unsuccessfull!&lt;/h1&gt;';
} else {  ////////////////////////////////////////////////////////////////////////////////// ADDED ELSE STATEMENT
    echo '&lt;h1&gt;No file was selected.&lt;/h1&gt;';
    $errors = 1;

//If no errors registred, print the success message
if(isset($_POST[‘Submit’]) && $errors != 1) /////////////////////////////////////////////////////////////// CHANGED
echo “<h1>File Uploaded Successfully! Try again!</h1>”;
