Hi Giuseppe
see
http://pomerape-dev.c2c/~ochriste/doc/user.query.html#user.query.mapfile.metadata
for info about query_returned_attributes
as for retrieving the point coordinate, I would say using a point with a
buffer would be more efficient than storing a polygone, though im not a
specialist in the matter.
have a look at builtin functions in postgis, maybe there is one that would
do exactly what you need.

Hi Oliver,
at least I've just finisched to write the rtf plugin, now I can manage a
stack of possible documents.
Now I can focus on the super layer feature. I've read the query plugin.
Anyway by seeing the .map of demo plugin I see the following quaryble
layer:
LAYER
NAME "lake"
TYPE POLYGON
DATA "inwatera"
TRANSPARENCY 70
METADATA
"id_attribute_string" "OGC_FID|string"
"query_returned_attributes" "AREA"
END
TEMPLATE "ttt"
CLASS
NAME "lake"
STYLE
COLOR 180 180 240
OUTLINECOLOR 0 0 180
END
END
END
there is no postgis connection . While I was writng the following one:
LAYER # query layer using the loccoords PostgreSQL table
NAME point_to_mark
CONNECTIONTYPE postgis
CONNECTION "user=postgres1 password=password dbname=my_country
host=localhost port=5432"
DATA "the_geom from super_layer_tab"
STATUS ON
TYPE POINT
BUFFER 5
CLASS
NAME "point_to_mark"
STYLE
SYMBOL "circle"
SIZE 5
COLOR 255 0 0
OUTLINECOLOR 0 0 0
END
END
In the former there is "Area" which should be the returned and displayed
string, nut in the latter there is no info about the column table which I
've to read to transfer the link.
Could you say me which is the right solution ?
As far as I know I have to add and customize the query.ini in server and
client conf.
Finally I 've to customize the tablerules.
In order to catch the point , do you advice me to choose a polygon area or
a
point into a sensible circle area ?
Thanks in advance and best reagards
Giu

you use the standart Query plugin, but you add some tableRules.
tableRules
are functions that will format a query result before it is displayed in
the
page.
this would allow you to format the result so it doesnt get displayed as a
normal query result (in an html table) but in a hidden <div> element, for
example.
see
http://www.cartoweb.org/doc_head/docbook/xhtml/dev.newplugin.html#dev.newplugin.special.tables
and there is an exemple in the "cartoweb for beginner" workshop we have
there: http://www.cartoweb.org/cwiki/Foss4g06Workshops
Then, you make a javascript script that will be triggered "onLoad",
meaning
everytime the page finish to load. That script will check if the hidden
div
exit ( if (xGetElementById('myHiddenDiv')) for example) and if that div
contain a link ( if (xGetElementById('myLink')) if you give an id to the
<a
href=".." id="myLink">...</a> ) you then get the href value with
javascript
and then do a windows.open() with the link you just recovered.

Oliver
