Re: [UMN_MAPSERVER-USERS] Enable 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.
 
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,
Xiaopeng

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");
 
 
regards,
 
Jacob

Subject: [UMN_MAPSERVER-USERS] Enable zip file downloading from query results

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
