any reason why PHP upload script would work on PC but not Mac?

[lawrence]

The following upload script seems to be working on PCs but not on
Macs. Can anyone imagine a reason why? Could there be something in the
form that turns in flawed data, or could IE on a Mac not pass along
certain data that Netscape and IE do on a PC?


function standardImageUp load() {
$controllerForA ll = & getController() ;
$insertObject = & $controllerForA ll->getObject("McT ransactions", " in
standardImageUp load().");
$formatTextObje ct = & $controllerForA ll->getObject("McF ormatText", "
in standardImageUp load().");
$resultsObject = & $controllerForA ll->getObject("McR esults", " in
standardImageUp load().");

$config = getConfig();
$pathToImageFol der = $config["pathToImageFol der"];
$imagesFolder = $config["imagesFold er"];

global $uploadedFile, $uploadedFile_s ize, $uploadedFile_n ame;

if (!$uploadedFile ) {
$uploadedFile = $controllerForA ll->getVar("$uploa dedFile");
$uploadedFile_s ize =
$controllerForA ll->getVar("$uploa dedFile_size");
$uploadedFile_s ize =
$controllerForA ll->getVar("$uploa dedFile_size");
}
$uploadedFile_n ame =
$formatTextObje ct->processFileNam e($uploadedFile _name);
$uploadedFile_n ame = htmlspecialchar s($uploadedFile _name);
// 04-20-04 - we need to keep hackers from uploading files with PHP,
or if they do, we need to keep those files
// from being sent to the PHP parser. So we look for typical PHP
extensions.
$fileSafe = true;
$ext = substr($uploade dFile_name, -4);
if ($ext == "php3") $fileSafe = false;
if ($ext == ".php") $fileSafe = false;
if ($ext == ".inc") $fileSafe = false;
if ($ext == "phtm") $fileSafe = false;

$ext = substr($uploade dFile_name, -5);
if ($ext == "phtml") $fileSafe = false;
if ($fileSafe) {
$absolutePath .= $pathToImageFol der.$uploadedFi le_name;
$urlPath .= $imagesFolder.$ uploadedFile_na me;

if (is_dir($pathTo ImageFolder)) {
if (!file_exists($ absolutePath)) {
if (copy($uploaded File, $absolutePath)) {
$resultsObject->addToResults(" Success: The image or file
'$uploadedFile_ name' has been uploaded. If you wish to reference it
this is the address: <a href='$urlPath' >$uploadedFile_ name</a>");
} else {
if ($uploadedFile_ size > 2000000) {
$resultsObject->addToResults(" Error: the upload failed. Your
file of '$uploadedFile_ name' is not uploaded. It is very large, with a
size of $uploadedFile_s ize. This may have been a factor in its
failure.");
} else {
$resultsObject->addToResults(" Error: the upload failed. Your
file of '$uploadedFile_ name' is not uploaded.");
}
}
} else {
$resultsObject->addToResults(" Error: a file with the same name as
the one you are uploading already exists. Please delete the old file
first, and then upload the new one.");
}
} else {
$resultsObject->error("We tried to copy the image to the image
folder that is specified in your site's configuration, yet the folder
doesn't seem to be there.", "standardImageU pload");
}
$controllerForA ll->import("standa rdInsert", " in
standardImageUp load().");
standardInsert( );
} else {
$resultsObject->addToResults(" <b>Error:</b> Terribly sorry, but it
looks like you're trying to upload a PHP file. For security reasons,
this is not allowed. The extension on your file was '$ext'.");
}
}

the reason could be something in the form, but unfortunately I don't
see any <form> tag in your code ;-)

The most likely reason why forms do not work on some browsers is, that
you forgot to fill the "action" parameter in your form-tag correctly.
Some browsers (like IE on Windows) assume the same URL when this tag
is empty. But not all Browsers are so forgivable about that.

So it is obviously not a PHP problem, because PHP works regardless of
the browser type and OS because unlike JavaScript it runs on the
server, not in the browser.

Below you can see the entire form. Do you see something here that
would throw a flaw on a Mac?

}
else
{
Img.src = filename;
ppImg = Img.src;
