Re: [UMN_MAPSERVER-USERS] 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");
 
 
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
