Image Upload with thumbnail creation stuck and lost

[djwinder]

I have been trying to get the below code working, it is a mix of two seperate files one which uploads files (red code) which works and thumbnail generation which isnt working yet and i cant see why. all the file paths are correct, any help would be aprishiated greatly as i just cant see the problem. I am very new to PHP and feel it could be something very simple that i just dont know.

<?php

$thumbw=100; //The Width Of The Thumbnails $nw
$thumbh=75; //The Height Of The Thumbnails $nh

if ( $_FILES['image'] ['name'] != "")

{
$uploadedFile = $FILES['image']['tmp_name'];
$newFile = $SERVER['DOCUMENT_ROOT']."/shop/admin/images/".$FILES['image']['name'];
$newtempfile = $SERVER['DOCUMENT_ROOT']."/shop/admin/images/thumbs/".$_FILES['image']['name'];

}

move_uploaded_file($uploadedFile, $newFile);

$image = $uploadedfile;

$dimensions = GetImageSize($image);

$thname = "$thumbpath/$img_name";

$width=$dimensions[0];

$height=$dimensions[1];

$tempimage = ImageCreateFromJpeg($image);

$thumb=ImageCreateTrueColor($thumbw,$thumbh);

$wm = $width/$thumbw;
$hm = $height/$thumbh;

$h_height = $thumbh/2;
$w_height = $thumbw/2;

if($width > $height){

$adjusted_width = $width / $hm;
$half_width = $adjusted_width / 2;
$int_width = $half_width - $w_height;

ImageCopyResampled($thumb,$tempimage,-$int_width,0,0,0,$adjusted_width,$thumbh,$width,$height); 
ImageJPEG($thumb,$thname,95); 

}elseif(($width < $height) || ($width == $height)){

$adjusted_height = $height / $wm;
$half_height = $adjusted_height / 2;
$int_height = $half_height - $h_height;

ImageCopyResampled($thumb,$tempimage,0,-$int_height,0,0,$thumbw,$adjusted_height,$width,$height); 
ImageJPEG($thumb,$thname,95); 

}else{
ImageCopyResampled($thumb,$tempimage,0,0,0,0,$thumbw,$thumbh,$width,$height);
ImageJPEG($thumb,$thname,95);
}

move_uploaded_file($thumb, $newthumbfile);

imagedestroy($tempimage);
?>

Hi!
Here is a script I have. Combined with your scrip it goes like this:

$root    = $_SERVER['DOCUMENT_ROOT'];
$imgName = $_FILES['image']['name'];

$uploadedFile = $_FILES['image']['tmp_name'];
$newFile      = $root.'/shop/admin/images/'.$imgName;
$thumbFile    = $root.'/shop/admin/images/thumbs/'.$imgName;

// After this you should forget the the $uploadedFile and consentrate on the $newFile
move_uploaded_file($uploadedFile, $newFile);

$maxThumbW = 100;
$maxThumbH = 75;

// Make a copy of the orginal one.
$orginal  = imagecreatefromjpeg($newFile);

// Get size.
$orginalW = $thumbW = imagesx($orginal);
$orginalH = $thumbH = imagesy($orginal);

// Resize the thumb if nessesary.
if($thumbW > $maxThumbW || $thumbH > $maxThumbH) {

$pros = $width > $maxW ? $maxW / $width : $maxH / $height;

$pros = $thumbW > $maxThumbW ? $maxThumbW / $thumbW : $maxThumbH / $thumbH;
$thumbW  = round($thumbW * $pros, 0);
$thumbH = round($thumbH * $pros, 0);

if($thumbW > $maxThumbW || $thumbH > $maxThumbH) {
	$pros = $thumbW > $maxThumbW ? $maxThumbW / $thumbW : $maxThumbH / $thumbH;
	$thumbW  = round($thumbW * $pros, 0);
	$thumbH = round($thumbH * $pros, 0);
	}
}

// Create the 'empty' thumb.
$thumb = imagecreatetruecolor($thumbW, $thumbH);

// Copy orginal image to the thumb.
imagecopyresized($thumb, $orginal, 0, 0, 0, 0, $thumbW, $thumbH, $orginalW, $orginalH);

// Save the thumb.
ImageJpeg($thumb, $thumbFile, 95);

I haven`t adden any error checking, so this is just to give you a hint. I havent tested this code because i have 'snap' it out of an other script i have.

Hope this help.
