line 230 is the error_reporting(E_ALL) and var_dump()

You.... misunderstood. The error_reporting function goes at the top, and you var_dump the returns from functions, or variables which you expect to be correct.

ok i get this end :)

thing is it works for line 122 cos i get my tumb image uploaded :S

Are you saying your problem is solved? Post your current code if it isn't.

no it not.... thing is my images get uploaded to tumbs folder

but it does not get uploaded to mini folder

Should be:

That is what is causing those undefined constant notices. The warning is because you still aren't using var_dump() properly. Go to the point where you think you have a problem, and var_dump($the, $variables, $you, $are, $using, $so, $you, $can, $see, $what, $their, $values, $are); You can also var_dump(functions_you_are_calling($with, $their, $params));

I have a script that does similar to this... it's a little more compact though. A basic run down of it is.

1. I upload 1 file to a temp folder. This is the base image I use to create the thumbnails.
2. I create the main image (which is a smaller version of the original).

3. I create the thumbnail image, which is created from the original image.

4. I unlink the temp base image to remove it from the server (as to conserve space).

My Code... it's a little rough because of the mysql and various error checking, and type checkings but she works good. I added comments so you can understand it better.
function addImage($id,$type="") {
global $_FILES, $config;
//Path to oringinal file.
$start = $config["path"]."examples/web_design/".$id.".jpg";
//Upload original file
copy($_FILES['image']['tmp_name'], $start);
//Path to larger thumbnail
$large = $config["path"]."examples/web_design/".$id."_lg.jpg";
//Path to smaller thumbnail
$small = $config["path"]."examples/web_design/".$id."_sm.jpg";
//Path to even smaller thumbnail
$featured = $config["path"]."examples/web_design/featured/".$id.".jpg";
//Call thumbnail function to make thumbnails.
// thumbnail( original , width , newpath , leave empty)
$copy = thumbnail($start,350,"$large","");
$copy = thumbnail($start,250,"$small","");
$copy = thumbnail($start,151,"$featured","");
//Remove the oringinal file to conserve space
unlink($start);
// return if successful for last thumbnail copy
if($copy) {
return "true";
}
else {
return "false";
}
}
//Thumbnail function
//Takes original image and resizes it to specified size
function thumbnail($i,$nw,$p,$nn) {
$img=imagecreatefromjpeg("$i");
$ow=imagesx($img);
$oh=imagesy($img);
$scale=$nw/$ow;
$nh=ceil($oh*$scale);
$newimg=imagecreatetruecolor($nw,$nh);
imagecopyresampled($newimg,$img,0,0,0,0,$nw,$nh,$ow,$oh);
imagejpeg($newimg, $p.$nn);
return true;
}

//Then to call the function
//$id = the image id (I use mysql to keep information about the photo so the $id corresponds to my mysql
//id for the image info). You can use whatever you want as the $id will be the new file names,
//with appropriate prefixs to distinguish the sizes of thumnails.
$upload = addImage($id);
if($upload == "true") {
echo "Success";
}
else {
echo "Failure";
}
