How to display all labels in openstreetmap in Wordpress?

Question

OpenStreetMap

Such a question, I use the ACF plugin on wordpress, created a field through the ACF OpenStreetMap Field extension and add the coordinates of each card there.

I am looking for an opportunity to display all the coordinates from all the cards on a separate page, i.e. make a map of all points from the site.
Maybe someone knows the necessary solution or some articles about this?

Answer 1

A separate page is created with an empty map.
When loading this page, there is an Ajax request to /wp-admin/admin-ajax.php

$.ajax({
        type: 'POST',
        url: '/wp-admin/admin-ajax.php',
        success: function(data) {
            markers = $.parseJSON(data);
            // добавляем маркеры на карту
        }
    });

On the server, we do select coordinates (in wordpress, it seems to be done through get_posts or wpdb).
We return this data using JSON to our client.
