Cakephp inheritng controller variable in function from another function variable

is there a way we can get variable from another function for the current function in controller and user set function to use in corresponding view file?

Sorry guys I meant passing view file variable to another view file...Below is the code...

function get_random_color()
{
        $c="";
    for ($i = 0; $i<6; $i++)
    {
        $c .=  dechex(rand(0,15));
    }
    return "#$c";
} 
$i = 0;//debug($trips);
foreach ($trips as $trip) {
    $colour = get_random_color();

    $numItems = count($trip['trip']['coords']);
    if($numItems > 3){
        $x = 0;
        echo 'var flightPlanCoordi开发者_开发知识库nates'.$i.' = [';
        foreach($trip['trip']['coords'] as $coords) {

            if($x+1 == $numItems) {
                echo 'new google.maps.LatLng('.$coords['latitude'].','.$coords['longitude'].') ';
            }
            else {
                echo 'new google.maps.LatLng('.$coords['latitude'].','.$coords['longitude'].'), ';
            }
            $x++;
        }

        /*
        for($x = 0; $x<sizeof($trip['trip']['coords']); $x++) {
            echo 'new google.maps.LatLng('.$trip['trip']['coords']['latitude'].','.$trip['trip']['coords']['longitude'].'), ';
        }*/


        echo ']; ';
        echo 'var flightPath'.$i.' = new google.maps.Polyline({
        path: flightPlanCoordinates'.$i.',
        strokeColor: "'.$colour.'",
        strokeOpacity: 1.0,
        strokeWeight: 4
        });';

        echo 'flightPath'.$i.'.setMap(map);';

        $i++;   
    }
}

You can do a requestAction, although it is considered the slower way to get at that data. If you give more details I might be able to give you a better answer.

$this->requestAction('/posts/list');

more on requestActions here: http://book.cakephp.org/view/991/requestAction

Use Configure class if you need a global variable in this situation,request action should be a bad choice.
