Hi Valerio
you have two possibilities:
extend the table plugin to output an extra variable to the template after a
query. In this case the selection will appear once.
or use tableTrules, to add an extra column in the query result table,
containing the selection coordinate.
Since the coordinates are the same for all the results, I think the first
option is better, but feel free to experiment ^_^
option 1:
create a new plugin,
class ClientMyProjectTables extends ClientTables { $coordinates;
public function replacePlugin() {
return 'tables';
}
public function handleHttpPostRequest($request) { if
(isset($request['selection_coords']) { $this->coordinates =
$request['selection_coords']; } } protected function
renderFormPrepare() { $smarty = new
Smarty_Plugin($this->getCartoclient(), $this);
$smarty->assign('tables', $this->tableGroups);
$smarty->assign('queryCoordinates', $this->coordinates);
$this->assignExportCsv($smarty); return
$smarty->fetch('tables.tpl'); }}and, if it is not already donw, overload the
table template in your project (copy tables.tpl in
/yourproject/coreplugins/tables/templates/) and add the new smarty variable
inside {$queryCoordinates}
option 2:
to add extra info in a query result, you can use the tableRules system in
cartoweb.
basically, it is a special kind of plugin that contain query result
modifications
I have attached an exemple file, containing a basic modification (adding a html
link in the query result table)
in the initialize() function, you define the type of action. In the exemple
"addCellFilter" which will add new data in an extra cell in each row of the
query result table . For a complet list of possible action, see:
http://www.cartoweb.org/doc/cw3.3/xhtml/dev.newplugin.html#dev.newplugin.special.tables
public function addCellFilter($groupId, $tableId, $columnId,
$inputColumnIds, $callback)$groupId is usualy
'query', $tableId is the name of the layer queried, $columnId is the name of
the column, $inputColumnIds is an array containing the IDs of the columns you
want to have at disposal when applying modification, $callback is an array
containing a reference to the current tableRule class and the function where
the modification will be done.this modification function must be declared
static public. It receive as parameters ($tableId, $columnId,
$inputValues)$tableId and $columnId are the same as described above.
$inputValues is an associative array containing the values of the selected
columns you passed with $inputColumnIds.then you can simply generate the
content of the new cell. For exemple recovering the selection coordinates as I
told you in my last email.Regards
Oliver

Oliver,
I added:
if (isset($request['selection_coords']) {
$this->coordinates = $request['selection_coords'];
}
in handleHttpPostRequest in coreplugins/query/client/ClientQuery.php file
(is the right file?)
How can I call coordinates string from tables.tpl file if I want to display
them with other query results?
Thank you
Valerio

Hi Valerio,
yes, each query return the coordinate of the point or selection on the map.
you can retrieve the data from the handleHttpPostRequest ( or
filterPostRequest, depending what you want to do with the values)
the variable name is "selection_coords"
for exemple, in handleHttpPostRequest :
if (isset($request['selection_coords']) {
$this->coordinates = $request['selection_coords'];
}
or in filterPostRequest :
if ($request->getValue('selection_coords') &&
!empty($request->getValue('selection_coords'))) {
this->coordinates = $request->getValue('selection_coords');
}
the coordinates are a string like this 'x,y' for point or
'xmin,ymin;xmax,ymax;...' for box
regards
Oliver
