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

[Ines]

Yes, is the same. I worked with 2 variables to try ('espe' and 'especie'). I
simplified the code again to work with just one variable ('especie'). I used
'espe' to take the value of 'especie' in DrawPublish(), and then use 'espe'
in 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' > ";
     $this->espe= $this->getVar('especie'); ----------------------- HERE
.............................................

But I doesn´t work.
For that reason, I simplified the code again and I work with just one
variable ('especie', the name of the input text) directly in ParseURL().
isVarSet in ParseURL() returns 0 (zero) ever and the content of $this->lb is
ever "no":

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);


	}
Thank you again
Ines

Hi,
Is it possible that this code is not the same as you shared with us
before? The if() statement in the widget you shared with us last week was:

if ($this->isVarSet('espe') == 0)
{
     $this->lb = "no";
}
else
{
     $this->lb = $this->getVar('espe');
}

Everything worked fine when I changed it for:
if ($this->isVarSet('especie') == 0)
{
     $this->lb = "no";
}
else
{
     $this->lb = $this->getVar('especie');
}

Is it the same for you?

Julien
