generating a hyperlink in query result
In
your query template, you could use the value from one of your shapefile
columns or database columns to build a URL.
Something like:
<a href="">[IMAGENAME]http://myserver.com/mydir/[IMAGENAME]">[IMAGENAME]</a>
or
<a href=""
href="http://myserver.com/mydir/[IMAGENUMBER].img">http://myserver.com/mydir/[IMAGENUMBER].img>[IMAGENUMBER].img</a>
If you wanted to use a URL to send the user
directly from a map click to the image, you could
use:
**note, URL templates only work in mode=query,
NOT in mode=nquery!
David.
I probably want the second way. A difference is
that the clickable links are not exactly the same as the attribute values in
the index, because I have to change a UNIX file path (e.g.,
/home/MyDir/1.img) to a Web-accessible path (e.g., http://SomeWeb/MyDir/1.img).
Thanks,
Xiaopeng

Help: generating a hyperlink in query result
Are you interested in having the user click on the map and be
directed automatically to another Web page? This could be done using
a URL as a query template and setting the mode to query.
Or, do you want the user to click on the map, presumably as a query
and return a page or text on the existing page that includes a list of
clickable links?
David.
Jacob, thank for your reply.
I think your method generates hyperlinks
after post-processing of query result. But I wonder if it is possible to
return hyperlinks to a uer directly when he/she clicks on the map. I
wonder it is possible?
Thanks,
Xiaopeng

[UMN_MAPSERVER-USERS] Help: generating a hyperlink in query
result
Hi Xiaopeng,
If the attribute value is simply
passed into the HTML, then it's simply a matter of putting in the
right HTML code:
<a href=""http://someWebsite/myDir/1.img">http://someWebsite/myDir/1.img"
target=#>Click for 1.img</a> (the target=# makes it
open in a new window)
I normally generate a directory
listing, and paste it into a spreadsheet (e.g. excel / openOffice
CALC), and split up the parts of the link, then concatenate them. For
example, imagine a row in a spreadsheet:
column
1: <a
href="".img
target=#>
column
4: click for image
column
5: 1
column 6:
</a>
column 7:
=concatenate(column1, column2, column3, column4,
column6)
Only column 2 and 5 will change (can
use autonumber). All other columns will hold the same value, and can
be copied across.
Hope this makes
sense.
regards,
Jacob
I have one index on raster images and it can
be displayed and queried through Mapserver.
I wonder whether it would be possible to
generate a hyperlink in query result.
The hyperlink will be generated based on one
attribute in the index.
I appreciate any suggestions or
ideas.
Thank you
Best regards,
Xiaopeng
