[Chameleon] How to include (join) php code in custom widget

[Julien-Samuel Lacroix]

Hi,

Sorry for the late response. Put your PHP where your $this->x=... is. 
This will give you a widget file like the following. Note that I will 
skip some part of the code to make the message shorter.

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

		// work some magic
if ( $this->isVarSet( "NAV_CMD" ) &&
                             $this->getVar( "NAV_CMD" ) == 'UUW' )
{
	if ( $this->mszCoords == 'aa')
	{

/////////////////////////////
// Put your code here
/////////////////////////////
$xml_file="./archivo4.xml";
$xml_data=implode("",file($xml_file));

//[...snip...]

			for($j = 0; $j < $tot_b; $j++)
			{
				$sc_name = $xml->response->content->record[$j]->ScientificName->_value;

				if($sc_name == "Inga oerstediana")
				{

/////////////////////////////////////////////////////
/// Here//////////////
////////////////////////////////////////////////
					$sc_name2= $xml->response->content->record[$j]->ScientificName->_value;
					$this->y= $xml->response->content->record[$j]->Latitude->_value;
					$this->x= $xml->response->content->record[$j]->Longitude->_value;
				}
			}
		}
		else
		{
//////////////////// Note that! /////////
return false;
		}


	}
	else
	{
//////////////////// Note that! /////////
return false;
	}
}
else
{
//////////////////// Note that! /////////
return false;
}

		//$this->lb = $this->getVar('especie');

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

		$poLayer = $this->moMapObject->oMap->getLayerByName('pointlatlon');
//[...snip...]
