file transfers

[scuba]

I guess a more precise question would be:

How can I transfer a photo from a directory from a users computer using a form, into a directory they have on a remote web server using php?

Thanks,
Steve

I have a form like:

<FORM ENCTYPE='multipart/form-data' ACTION='addphotosuccess.php' METHOD='POST'>
<input type='hidden' name='Loginusername' value='<?php echo($Loginusername);?>'>
<input type='hidden' name='userfile' value='<?php echo($userfile);?>'>
<INPUT TYPE='hidden' name='MAX_FILE_SIZE' value='1000'>
Send this file: <INPUT NAME='userfile' TYPE='file'><br><br>
<INPUT TYPE='submit' VALUE='Send File'>
</FORM>

which is in a php file. Onsubmit it go to another php file which looks like this:

<input type='hidden' name='Loginusername' value='<?php echo($Loginusername);?>'>
<input type='hidden' name='userfile' value='<?php echo($userfile);?>'>

<?php
function is_uploaded_file($userfile) {
if (!$tmp_file = get_cfg_var('upload_tmp_dir')) {
$tmp_file = dirname(tempnam('', ''));
}
$tmp_file .= '/' . basename($userfile);
/ User might have trailing slash in php.ini... /
return (ereg_replace('/+', '/', $tmp_file) == $userfile);
}

if (is_uploaded_file($userfile)) {
copy($userfile, "http://www.onecardexpress.net/temp17/$Loginusername/");
} else {
echo "Possible file upload attack: filename '$userfile'.";
}

?>

but I keep getting this error:

Possible file upload attack: filename 'none'.

anyone know why ?

thanks
