This is great. Yes I
think I will probably go this way you suggested. Thanks for the
hints.
But I found a small problem when use the
zipfile.php. After I downloaded the zipped file to my windows
machine via the zipfile.php, I could not use "extract to here" or "extract
to folder XXX" of the Winzip functionality, it complains that "start of central
directory not found; Zip file corrupt. Possible cause: file transfer error.".
But I was enable to double click the .zip file and
activate the Winzip window, then get individual files out in this way.
I am not sure whether I used the zipfile class right, I
passed "./" to add_dir() since the files to be zipped are in the same directory
as the .php file, and repeated passed a file name (e.g., test1.txt) to
add_file().
Thanks,
Xiaopeng

zip file downloading from query results
Hi Xiaopeng,
I think for a single file, you can
do:
<a href="">download
zipped file</a>
For downloading all files, I don't think there is a very
straightforward way to do this, except by building up a URL on the fly.
Perhaps you could use _javascript_ to add to the URL, for example at the
beginning of the template put:
url="";
and then for each record, do:
url+="[filename],";
then
at the end of the template:
url+="'>download
all</a>";
document.write(url);
This
is untested code, but I think that's how I would go about it. You would have
to change zipfile.php to read in url, and use "explode" to get the file from
the comma delimited list.

Jacob
Thanks for the help. It works on the server
side.
But there are still another part of the problem.
When the query result is returned to the
query template, how to access the "FileLink" attribute
of each record? And how to
send these FileLinks to server side PHP
file?
Thanks,
Xiaopeng

Enable zip file downloading from query results
Hi Xiaopeng,
There is a file from "Catalist Creative" on their
website, which does that:
I have used it a fair bit for this purpose. You
basically have to modify it to point to the right files. If you use it,
please make the following change, otherwise you will run into problems if
you try to open the zip-file straight from Internet
Explorer:
Before the lines that say "Header ("Content
........", put another line that says:
Header("Cache-Control: must-revalidate, post-check=0,
pre-check=0");

Hello List,
I am very new to this field. I
apologize if this question is not related but I do appreciate any
suggestions.
I have one index that can be queried using mapserver.
The query results are like follows:
Record |
UL_X | FileLink
Now what I want to realize is to provide an
additional "Download_All" button in the query result
page.
Then when the user clicks the "Download_All"
button, all the files in "FileLink" will be compressed online
into one (e.g., .zip) file and
downloaded.
How can this be realized? I'll apprecate any help
or some reference to read.
Thank you.
Best,
Xiaopeng
