Through the custom fields, I assigned to each post its geographic coordinates (latitude/longitude).
Now, I’d like to show a Google Maps with a marker for each post.
Do you have any suggestions on how to do this effectively?
EDIT: Solved following this G.M.’s answer.
Lots of ways to proceed here. Here’s one way to do it:
Generate the HTML markup that the above plugin will use. I needed a more user-friendly way to add markers, so I utilized ACF’s Repeater Field type for this because I had one page with a map, so it was easiest way to attach lat-lang coordinates to that page. Your case would probably be getting those posts with
WP_Query and extracting the coordinates from each.
Tie it all together with a shortcode, so that the map can be shown on any page. Again, you don’t need this, you can just include all the necessary JS, execute your
WP_Query, and generate the necessary HTML anywhere you want to show the map.
The best plugin I’ve found so far for this is Mappress…there is a pro version, which you might need. I’ve got it implemented here in the way you describe.
