What I would like to do is pull the latitude and longitude values from a database and show them on a google map with polygon lines
The polygon lines have been successfully created, but I would like to have this polygon line appear with zoom when clicking on a particular project from the database
This is my project table
ID
Project name
lat
lng
description
This is my land piece coord table
ID
project_id
lat
lng
I want to place my project on a map, so that when someone clicks the project, they see the land piece and its specifics
the code i already tried is https://www.webwiders.in/WEB01/cluster/
This is my controller
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Site extends CI_Controller {
public function __construct() {
parent::__construct();
$this->db->query("set sql_mode = ''");
}
public function index(){
$this->load->view('site/index');
}
?>
This is my view

In a table named properties, all properties are listed
| id | name | lat | lng | created_at |
|---|
Additionally, I have inserted properties land pieces (lat ,lng) in the table land_marks
| id | p_id | part | lat | lng | created_at |
|---|
