Thanks again, it works with: $shp->set('text', 'My Place');
I'll make the tutorial to add it to the wiki.

I need to solve another thing now. I created an "input text" in the function
"Draw publish". And I need to know how to take the value from that input
text. I tried  with the POST method in  "ParseURL" function but it don´t
read the value of the input text. Do you know How can I read the value of
the input text in the widget? I need to take that value in the Parse URL
function. I need to write something in the input text, and when I click the
widget button, take that value in Parse URL to use it like a variable.

function DrawPublish()
        // init vars
        $szReturn = "<font color='#000000' size='2' face='Arial, Helvetica,
sans-serif'>Search by scientific name </font><input type='text'
name='especie'>        ";

        // execute parent
        $szReturn .= parent::DrawPublish();

        // return
        return $szReturn;

    // end DrawPublish() function

In Parse URL I think it could be:

$this->lb=$_POST[especie];   //---------------> But it don't work, POST
don't read the value of "especie" input.

$poLayer = $this->moMapObject->oMap->getLayerByName('pointlatlon');
$poLayer->set("status", MS_ON);
$pt = ms_newPointObj();
$ln = ms_newLineObj();
$shp = ms_newShapeObj(MS_SHAPE_POINT);
$shp->set("text", $this->lb);

Thank you very much

Great idea! You can probably easily add that to the wiki:

Does $shp->set('text', 'My Place'); works?
