Hi again:
I have successfully implemented a class that uses the
code examples and suggestions from the good folks
on this list.
I have a few lingering issues:
1: When the code runs successfully, I do not get a detectable return
value.
the code sets $_out['success'] = true;
this should be passed out via the call to run() but the code that
watches the
return value does not seem to see anything (evidenced by no
report, where as
a return value of $_out[error] is detected and displayed in the
display page.
Q Why would this be?
2: To make this a bit more independent I have tried to use the
following test
if( strpos( self::$_input['targ'], getcwd()) < 0)
{
/*
0 can be a valid strpos integer. So doing !strpos() will also
fail because
it should be detected as starting at 0. I know the negative
return value may or may not
be FALSE according the my copy of the manual.
*/
$_file = getcwd().self::$_input['targ'];
}
meaning if the full path is not already present in the input value ,
the code should add it.
If the file will not resolve with the full path added, it won't be a
valid path/file; to add some
sanity checking.
But it is not seeing the situation as I have coded it: the input
file has path info relative
to the cwd. So the full path value should not be detected and the cwd
part should be added
3: Now to expand to being able to download directories with files and
sub directories.
( as for example downloading the php manual as chunked html )
Here is the full class def:
class _DOWNLOADER
{
private static $_class = '';
private static $_input = array();
public function __construct($_input) // $_input arg is $_POST;
{
self::$_class = get_class($this);
self::$_input = $_input;
}
public function run()
{
return self::downLoad();
}
private function downLoad()
{
$_out = array();
$_file = '';
$_cd = getcwd();
$_file = $_cd.self::$_input['targ'];
if(!is_file($_file))
{
$_out['error'] = self::$_class."->".__FUNCTION__."
error: ".$_file." not found"; //self::$_input['targ']
return $_out;
}
$_file = basename($_file);
$_fSize = filesize($_file);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.'"'.
$_file.'"');
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0,
pre-check=0');
header('Pragma: public');
header('Content-Length: ' . $_fSize);
ob_clean();
flush();
readFile($_file);
$_out['success'] = true;
return $_out;
}
}
