I am trying to select a country and return the regions related to it in CodeIgniter. everything is working but the new div is not refreshing instead it shows the returned values in the console instead of the browser page. Here is my attached controller function code.
Code:
public function post_action(){
if($_POST['country']){
$pid = array('pid'=>$_POST['country']);
$regions =$this->countries_model->getRegions($pid);
$html = '<select name="region" id="regions"> ';
foreach($regions as $rg){
$html .= " <option value=$rg[id]>$rg[name]</option>";
}
$html .="</select>";
// $output = '{ "message": "'.$html.'" }';
echo $html;
return;
// redirect('json/view_sites');
}
}
Here i sthe view that is calling this function
Code:
<!DOCTYPE html>
<html lang="en"><head>
<meta charset="utf-8">

<!--[removed][removed]-->

$(document).ready(function(){
$("select").change(function () {

dataType: "json",
data: "country="+country,

}
});
