RV: [Chameleon] Custom Widget, read value of input text in Draw Publish

[Ines]

Hello, I tried to read the variable but the widget don't take the value of
the input text.
I have just one input text box and the button of the wiget.
First, I write some text in te input text box. Example: hello
Second, I click the buttom of the widget, but the widget don´t read the
value of my input text box (hello). The name of my input is 'especie'.

I have defined the input text in DrawPublish() and I'm trying to read the
variable in the parseURL()

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;
    }
---------------------------------------------------

function  ParseURL()
    {
        // execute parent function
        parent::ParseURL();

if ( $this->isVarSet( "NAV_CMD" ) &&
                            $this->getVar( "NAV_CMD" ) == 'UUW' )
{
	$this->x = -85;
	$this->y = 13;
	if ( $this->mszCoords == 'aa')
	{
		if ($this->isVarSet('especie') == 0) -------------->RETURN 0 EVER
		{
			$this->lb = "no";
		}
		else
		{
			$this->lb = $this->getVar('especie');
		}
		$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);-------------------------> CONTENT= "no"
   		$pt->setXY($this->x,$this->y);
    	$ln->add($pt);
    	$shp->add($ln);
    	$poLayer->addFeature($shp);


	}


}

        // return success
        return true;
    }

Do I have to do something more for take the value of the variable?
Thank again
Ines

Hi,
To read any form variable anywhere in a widget use this:
$this->lb = $this->getVar('especie');

There's also the function $this->isVarSet('especie') that is used to
know if a variable is set or not in the form variables.
