printing multiple markup on google map using CI
i have lat lng saved in my DB. I want to place markup on those particular places. But my markup only appears on the lat lng which i defined in the google map file (saved in the library). When i echo the fetched lat lng on view page it only shows the 1st saved lat lng a开发者_运维问答nd the markup doesn't appear on that place.
Controller:
function index()
{
$this->googlemaps->initialize();
$marker = array();
$this->main_model->get_map();
$marker['position '] = $this->main_model->get_map();
$data['r'] = $marker['position '];
$this->googlemaps->add_marker($marker);
$data['map'] = $this->googlemaps->create_map();
$this->load->view('main_view',$data);
}
Model:
public function get_map()
{
$this->db->select ('lat,lng');
$sql = $this->db->get('info');
if ($sql->num_rows () >0)
{
foreach($sql->result() as $row) {
$data[] = $row;
}
return $data;
}
View:
<? foreach($r as $row): ?>
<?echo $r[0]->lat; ?>
<?php echo $map['html']; ?>
<?php endforeach; ?>
Looks like you're using my CodeIgniter Google Maps Library. The problem you face is the order that you are doing things in. Try doing something like so: (untested)
Controller:
function index() {
// initialize the map
$this->googlemaps->initialize();
// get the markers, loop through the markers and add them to the map
$infoMarkers = $this->main_model->get_map();
foreach ($infoMarkers as $infoMarker) {
$marker = array();
$marker['position'] = $infoMarker->lat.",".$infoMarker->lng;
$this->googlemaps->add_marker($marker);
}
// create the map with added markers
$data['map'] = $this->googlemaps->create_map();
// load your view
$this->load->view('main_view',$data);
}
Model:
public function get_map()
{
$data = array();
$this->db->select ('lat,lng');
$sql = $this->db->get('info');
if ($sql->num_rows () >0)
{
foreach($sql->result() as $row) {
$data[] = $row;
}
}
return $data;
}
View:
<html>
<head>
<?php echo $map['js']; ?>
</head>
<body>
<?php echo $map['html']; ?>
</body>
</html>
Notice how the lat/lng's are looped through in the controller. Foreach iteration we call the add_marker function to add each individual marker.
Hope that helps! Check out the demos too as they may help clear things up :)
