Enable zip file downloading from query results

[Delfos, Jacob]

It is probably because of your add_dir. Try doing this:
 
$zipdir = realpath(./yourfile.img);
add_dir($zipdir);
 
basically, realpath turns a relative path into an absolute path. This is
the approach I have used to get the right path for this script.

Jacob

	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

		Hi Xiaopeng,
		 
		I think for a single file, you can do:
		<a href="zipfile.php?filename=[filename]">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="<a href=zipfile.php?filename='";
		 
		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.
		 
		regards,
		 
		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,

				Hi Xiaopeng,
				 
				There is a file from "Catalist Creative"
on their website, which does that:
				 
	
http://www.catalistcreative.com/tools/zipfile.php.txt
				 
				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");
				 
				 
				regards,
				 
				Jacob

				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
				1                456000
http://myweb.com/photo/15.tif
				2                460000
http://myweb.com/photo/38.tif
				3                464000
http://myweb.com/photo/41.tif
				 
				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
