I have my View working so that it shows an infoWindow with a clickable "thumb up/thumb down" for a property that a User is looking at.
However, I cannot get the logic to work for calling an appropriate function within the model or controller such that I am able to run an update to the database reflecting the Users desire.
I do not want the page to have to reload, so all I want is that ability to tell the controller (or model) when a state change to the thumb occurs.
What is the right way to approach doing this?
Controller
Code:
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Maptest extends CI_Controller {
function __construct() {
parent::__construct();
// Load form validation ibrary & user model
$this->load->library('form_validation');
$this->load->model('mapModel');
// User login status
$this->isUserLoggedIn = $this->session->userdata('isUserLoggedIn');
}
public function index($incoming = null){
//need to load a view
if($incoming == 5) {
return;
}
//test function for sending data to view
$data = array('lat' => 32.7157,
'long' => -117.1611 ,
'zoom' => 10 );
$data = $this->mapModel->getPropertyMarkers();
//var_dump($data);
$data['markers'] = $this->mapModel->getPropertyMarkers();
$string = $this->load->view('maptest/index', $data , FALSE);
}
}
Model
Code:
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class MapModel extends CI_Model{
function __construct() {
// Set table name
$this->table = 'users';
}
public function getPropertyMarkers($data = null) {
//ideally this function will return the property markers
//with $data having different arugments to cull out the properties
//not desired...
//OR there will be a list of propert ID's in $data that will then let this function get
//the desired rows from the property table
//for now, just return all rows
$this->db->select('lat, long, property_name');
//$this->db->from('property');
$query = $this->db->get('property', 5, 5);
return $query->result_array();
}
}
View: in myFunction is where I "want" to call a Controller or Model function using the various procedures that "should" work at calling a function from a View, but $this->CI =& getInstance() fails miserably when the code generates within the script for creating the map and markers, as the $this is referring to the View, and I can't figure out how to pass in the pointer to the Controller...
