creating queryable shapefiles

[Trond Michelsen]

Hi.

I'm using mapserver, and I need to create a shapefile from a list of
coordinates that I have, and I need to display this layer as points,
which can be clicked on for further information about that point.

Anyway - I have made this small perl-program that generates the
shapefile, and it the layers loads fine in mapserver. Except that I
can't click on it.

--8<--
#!/usr/bin/perl

use strict;
use warnings;
use Geo::Shapelib ':constants';

my $shape = Geo::Shapelib->new();

$shape->{Shapetype} = MULTIPOINT;

$shape->{FieldNames} = ['testpoints'];
$shape->{FieldTypes} = ['String:60'];

while (<>) {
    chomp;
    my ($name,$x,$y) = split;
    push @{$shape->{Shapes}}, {
        SHPType  => MULTIPOINT,
        Vertices => [[$x,$y]]
        };
    push @{$shape->{ShapeRecords}}, [$name];
}

$shape->save('mylayer');
--8<--

names and coordinates are piped through STDIN

In the mapfile, the web- and layer-objects look like this:

 WEB
  TEMPLATE "printable.html"
  EMPTY "/empty.html"
  imagepath "/var/www/html/tmp/"
  imageurl  "/tmp/"
 END

 LAYER
  name "mylayer"
  data mylayer
  status default
  type point

  CLASS
   name "testpoints"
   color 0 255 0
   outlinecolor 0 0 0
   template test.html
   STYLE
    color 123 123 0 # dummy color
    symbol 'circle'
    size 6
   END
  END
 END


Whenever I make a query, I always get redirected to empty.html

Here's an example of the query request, as taken from the log:

GET /cgi-bin/mapserv
 ?mode=query
 &map=/var/www/test.map
 &qlayer=mylayer
 &layers=
 &imgext=-386503.564521+-3634774.809739+684073.545134+-2971595.143072
 &imgsize=1109+687
 &imgxy=628+118

(and I'm pretty sure the pointer was above the point when I clicked ;)

Any suggestions of what I'm missing to make my shapefile
clickable/queryable?
