If you upload logo.png and echo it : logo.png

If you upload logo444.png and echo it : logo444.png

I hope you can see the differences.

In order to overwrite a file that name has to be the same name

If you upload logo.png and echo it : logo.png

If you upload the same name but different file logo.png and echo it : logo.png overwrite the first one.

but i cant fix the problem.theres no error but the logo is not uploading this is my code for action

I'm not quite sure what you asking right now? You are asking 2 different questions.

1) Rename file

or

2) Logo not loading

or

3) Either is not working?

<?php include("../includes/config.php");?>
<?php
if(isset($_FILES["file"]))
{
if ((($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/pjpeg"))
     && ($_FILES["file"]["size"] < 1000000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
        echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }

        if (file_exists("../graphics/" . $_FILES["file"]["logo.png"]))
          {
              echo $_FILES["file"]["name"] . " already exists. ";
          }
        else
          {
              move_uploaded_file($_FILES["file"]["name"],
              "../graphics/" . $_FILES["file"]["logo.png"]);
              echo "Stored in: " . "../graphics/" . $_FILES["file"]["logo.png"];
          }
    }
  }
else
  {
      echo "Invalid file";
  }
?>
<?php
$title=$_POST["title"];
$theme=$_POST["theme"];
$con=mysql_connect($dbserver,$dbusername,$dbpassword);
if (!$con) { die('Could not connect: ' . mysql_error()); }

mysql_select_db($dbname, $con);
$result=mysql_query("SELECT * FROM setup WHERE id=".$_SESSION['id']);
$num_rows = mysql_num_rows($result);
if ($num_rows > 0)
{
   {
mysql_query("UPDATE setup  SET title='".$title."' , theme='".$theme."'WHERE id=".$_SESSION['id']);
 header("Location:setup.php?status=1");

What do you want to do? I mean if you can't upload the logo.png, then it's pointless what you mention above.

I think you need to fixed the upload form first. I can't really help you if you just keep telling me solve your code when you can't upload anything?
