Past data between a popup and mask while popup is open

i was able to simulate the digicel page that sends text messages to your contacts. on clicking on one of your contacts, it passes that name to a specific area. if you try to add the same name, it gives a javascript alert that lets you know that the contact was already added to the area to be sent a text message.

the code is below:

class popup_horses extends P4A_Mask {

var $selected_horses;
var $p4a;

function popup_horses(){

parent::p4a_mask();

$this->selected_horses = array();
$this->p4a = & p4a::singleton();

$this->checkIfHorsesWerePreviouslyAdded();

$page = & $this->showPage();

$this->intercept($this->Tbl->rows, 'afterClick', 'validatedSelectedHorse');
$this->display('main', $page);
}

function addPreviouslySelectedHorseNamesToArray(){

$horse_names = $this->getAllPreviouslyAddedHorseNames();
$temp_array = explode(',', $horse_names);

foreach ($temp_array as $temp){
array_push($this->selected_horses, trim($temp));
}
}

function checkIfHorsesWerePreviouslyAdded(){

if($this->isHorseAreasEmpty() == false){
$this->addPreviouslySelectedHorseNamesToArray();
}
}

function getAllPreviouslyAddedHorseNames(){
return $this->p4a->masks->parent_mask->taHorses->getNewValue();
}

function addSelectedHorseToArray($horse_name){
array_push($this->selected_horses, $horse_name);
}

function addSingleHorseToArea($horse_name){
$p4a = & p4a::singleton();
$p4a->masks->youtube_channel_archive->taHorses->setNewValue($horse_name);
}

function addHorseToAreaWithSeparator($horse_name){

$p4a = & p4a::singleton();
$horse_area_value = & $p4a->masks->parent_mask->taHorses->getNewValue();
$horse_area_value .= ", $horse_name";
$p4a->masks->parent_mask->taHorses->setNewValue($horse_area_value);
}

function validatedSelectedHorse(){

if(in_array($this->fields->horse_name->getNewValue(),$this->selected_horses)){
$this->showMessage("Horse already added", "warning");

hope someone was able to understand this and it was what someone wanted to do what they wanted to do.
