I am having problem with this coding, the upload works fine just that, if I didn't upload any picture it will echo the error, if I upload just one picture it won't show any error message, now I want to make it if nothing to be uploaded, it won't echo the error message but I wanted to remain the error message just incase something went wrong I know there is problem. Thanks!

```
// Upload begins!!

if ($_FILES['ufile']['name'][0] != "")
    {
    $target_path =  "."."/uploads/".$petname."/".$_FILES['ufile']['name'][0];

    copy($_FILES['ufile']['tmp_name'][0], $target_path);
    $filesize1=$_FILES['ufile']['size'][0];
    }

    if ($_FILES['ufile']['name'][1] != "")
    {
    $target_path1 =  "."."/uploads/".$petname."/".$_FILES['ufile']['name'][1];

    copy($_FILES['ufile']['tmp_name'][1], $target_path1);
    $filesize2=$_FILES['ufile']['size'][1];
    }

    if ($_FILES['ufile']['name'][2] != "")
    {
    $target_path2 =  "."."/uploads/".$petname."/".$_FILES['ufile']['name'][2];

    copy($_FILES['ufile']['tmp_name'][2], $target_path2);
    $filesize3=$_FILES['ufile']['size'][2];
    }

// Check for error!!
    if($filesize1 || $filesize2 || $filesize3 != 0) 
    {
    }

// If got error, show message 
    else 
    {
    echo "<div class='error'>ERROR : There seems to be problem uploading the pictures.</div>";
    }
