Error in code with Joomla API 1.5: to use a variable that receives a post request with JRequest:: getVar

I am using the joomla framework to return values from a POST request, and the print screen shows me data, but when using the array in sending me to a method and print or send me data.

Here I put the code that I've got gray hair,thanks in advance.

This is the controller:

/**
 * Construct (registers additional tasks to methods).
 */
function __construct(){
    parent::__construct();

    //Registro de tareas extra
    $this->registerTask('add','ingresarPlanilla');
}//function


function ingresarPlanilla(){

    // Comprueba del request la clave de falsificación
    //JRequest::checkToken('post') or die( 'Objeto invalido' );

    $task = JRequest::getVar('task');

    $model = &$this->getModel('planilla');

    if ($returnid = $model->ingresar()) {
        switch ($task) {
            case 'add' :
                $link = '?option=com_mercurio&view=planilla&controller=planilla&task=add';
                break;
            default :
                $link = 'index.php?option=com_mercurio&view=planilla';
                break;
        }   
        $msg = JText::_( 'PLANILLA INGRESADA' );
        $cache = &JFactory::getCache('com_mercurio');
        $cache->clean();
    } else {
        $msg = 'PLANILLA NO INGRESADA';
        $link = 'index.php?option=com_mercurio&view=planilla';
    }
    //$model->checkin();
    $this->setRedirect($link, $msg);
}

}

This is the model:

    $cliente = new SoapClient(URLMERCURIOWS.URLWSPLANILLA, array('login'=>LOGINWS,'password'=>PASSWORDWS));

    if (is_soap_fault($cliente)) {
        trigger_error("SOAP Fault: (faultcode: {$arr->faultcode}, faultstring: {$arr->faultstring})", E_USER_ERROR);

        return false;
    }

    $postost = JRequest::get( 'post', JREQUEST_ALLOWHTML );


    $postost['cdPoblacionOrigen']    = JRequest::getVar('cdPoblacionOrigen', '', 'post', 'cdPoblacionOrigen');
    $postost['nmSecDniCliente']    = JRequest::getVar('nmSecDniCliente', '', 'post', 'nmSecDniCliente');
    $postost['cdAgenciaCliente']    = JRequest::getVar('cdAgenciaCliente', '', 'post', 'cdAgenciaCliente');
    $postost['nmPesoTransportado']    = JRequest::getVar('nmPesoTransportado', '', 'post', 'nmPesoTransportado');
    $postost['nmVolumenTransportado']    = JRequest::getVar('nmVolumenTransportado', '', 'post', 'nmVolumenTransportado');
    $postost['nmUndsTransportadas']    = JRequest::getVar('nmUndsTransportadas', '', 'post', 'nmUndsTransportadas');

    $planilla = array();
    $planilla = $postost;

    echo $postost['cdPoblacionOrigen']."</br>"; 
    echo $postost['nmSecDniCliente']."</br>";
    echo $postost['cdAgenciaCliente']."</br>";
    echo $postost['nmPesoTransportado']."</br>";
    echo $postost['nmVolumenTransportado']."</br>";
    echo $postost['nmUndsTransport开发者_JAVA百科adas']."</br>";


    $cliente->ingresarPlanilla( AGENCIAXDEFECTO, null, null, null, $postost['cdPoblacionOrigen'], $post['nmSecDniCliente'],  $post['cdAgenciaCliente'],  null, $post['nmPesoTransportado'],  $post['nmVolumenTransportado'],  $post['nmUndsTransportadas'], null, null,  null,  null,  null, null,  null,  null,  null);

    return true;
}

This is the view:

You can use this line below to read all POST data into an array with key value pairs.

$post = JRequest::get('post');

This will load all values into an array. So you would use the above like so:

$post = JRequest::get('post');
echo $post['cdPoblacionOrigen']; // prints value of post for input with name 'cdPoblacionOrigen'
