cant get copy or move_uploaded_file to work

[ukfusion]

Im trying to get an image upload script to work within a session file.....i can get it to work on a single page without any other script....but i need to have the image upload facility built into a add product form....so the script is currently sitting in a session file at the same point as where the fields are all validatedd....i've tried using copy and move_uploaded_file.

I know the structure of the code is probably not great but i cant seem to find out why it wont work.

$subimgfile is the variable name for $_FILES['imgfile']['name']
and $subimgfiletype is the variable name for $_FILES['imgfile']['type']

if ($subimgfile)
{
$uploaddir = "./product_images";
if (($subimgfiletype != "image/gif")  && ($subimgfiletype != "image/jpeg") && ($subimgfiletype != "image/pjpeg"))
    {
       $form->setError($field, "* Image Must be .jpg / .jpeg or .gif, your file had extension $subimgfiletype");
        unlink($subimgfile);
    }
    $imgsize = GetImageSize($subimgfile);
    if (($imgsize[0] > 531) || ($imgsize[1] > 398)) 
    {
        $tmpimg = tempnam("/tmp", "MKUP");
        system("djpeg $subimgfile >$tmpimg");
        system("pnmscale -xy 531 398 $tmpimg | cjpeg -smoo 10 -qual 80 >$subimgfile");
        unlink($tmpimg);
    }
$final_filename = str_replace(" ", "_", $subimgfile);
$FileCounter = 1; 
while (file_exists( 'product_images/'.$final_filename )) 
  $final_filename = $FileCounter++.$final_filename; 
    $newfile = $uploaddir . "/$final_filename";
    if (!copy($subimgfile,"$newfile")) 
       {
          $form->setError($field, "* Error uploading file");
       }
    unlink($subimgfile);
}

You need to troubleshoot your code. I don't know what those system calls do and what tempnam() does or what you're trying to do with image facilities and add product forms.

Maybe you can describe your problem in a more technical way?

Note: you do know that $_FILES['imgfile']['name'] is only the name of the file, not where it is stored on the server, right? see $_FILES['imgfile']['tmp_name']

Hi,

Thanks for pointing that out.....i kind of knew that but still didnt realise that was my porblem....which it was sot thanks.

The only part i cant get to work now is the resizing

$imgsize = GetImageSize($subimgfile);
    if (($imgsize[0] > 200) || ($imgsize[1] > 200)) 
    {
        system("djpeg $subimgfile >$subimgfiletmp");
        system("pnmscale -xy 200 200 $subimgfiletmp | cjpeg -smoo 10 -qual 80 >$subimgfile");
    }

$subimgfile is the $FILES['imgfile']['name'] and
$subimgfiletmp is the $FILES['imgfile']['tmp_name']

I presume this will only work for jpegs....is there a resize script that will work for both gif and jpegs....cheers.

@ukfusion
you could try PHP’s GD library.
