Paste in function.php file

 function insert_cordova_message(){

 if(function_exists('date_default_timezone_set')) {
    date_default_timezone_set("Asia/Kolkata");
}

// then use the date functions, not the other way around
$date = date("d/m/Y");
$date1 =  date("H:i a");


$person = $_POST['person'];
$email = $_POST['email'];
$phone = $_POST['phone'];

global $wpdb;
$table_name = $wpdb->prefix ."customer";
$wpdb->insert($table_name, array('person' => $person, 'email' => $email,'phone' => $phone, 'password' => $password,'registered_date' => $date) );



  die();
 }

 add_action('wp_ajax_nopriv_insert_cordova_message','insert_cordova_message');
 add_action('wp_ajax_insert_cordova_message','insert_cordova_message');


function add_cors_http_header(){
    header("Access-Control-Allow-Origin: *");
}
add_action('init','add_cors_http_header');

add_filter( 'wp_headers', 'send_cors_headers', 11, 1 );
function send_cors_headers( $headers ) {
