[Cartoweb-users] Tooltip plugin.

[Oliver Christen]

Hi

all you can do is recovering the sql query generated by the plugin and try 
it directly into your postgres. This will tell you if the problem comes from 
the query or from the data.
you can do that by replacing
        return sprintf('SELECT %s FROM %s ' .
                       "WHERE %s && setSRID('%s'::box3d, %s) ".
                       "AND Distance(%s, GeometryFromText( '".
                       "POINT(%s %s)', %d ) ) < %s",
                       $this->getReturnedAttributes(),
                       $this->dbTableName,
                       $this->dbGeomColumnName,
                       $bbox3D,
                       $this->srid,
                       $this->dbGeomColumnName,
                       $geoX,
                       $geoY,
                       $this->srid,
                       $toleranceGeo);

by

        $sql = sprintf('SELECT %s FROM %s ' .
                       "WHERE %s && setSRID('%s'::box3d, %s) ".
                       "AND Distance(%s, GeometryFromText( '".
                       "POINT(%s %s)', %d ) ) < %s",
                       $this->getReturnedAttributes(),
                       $this->dbTableName,
                       $this->dbGeomColumnName,
                       $bbox3D,
                       $this->srid,
                       $this->dbGeomColumnName,
                       $geoX,
                       $geoY,
                       $this->srid,
                       $toleranceGeo);


      print $sql;
      return $sql;
in file QueryableLayer.php

modifying the behaviour of the tooltips javascript is certainly possible but 
not easy, due to the complexity of Cartoweb javascript framework.
also, the tooltips tool do not have a "state" like zoom or pan or query, it 
is always on. If you wanted to have it react on click only, you would need 
to modify the tooltips php class and implement the toolprovider interface 
and define a specific tool for it which would then appear in the toolbar. so 
user would have to specificaly select that tool to by able to get info on 
clic, then switch back to another tool to continue navigating.
