Adding TONS of locations – Grid or Preload less markers

If you go to settings -> Markers -> Enable marker clusters then it will merge markers together is they are close to each other.

Limiting the max location load is something you would need to hard code for now ( this will be an option on the settings page in the next version ).

If you open the /frontend/wpsl-ajax-functions.php, then replace the code from line 26-31 with this ( untested ).

$sql_part = ' ORDER BY distance LIMIT %d';
$placeholders = array(
   $_GET["lat"],
   $_GET["lng"],
   $_GET["lat"],
   '10'
);

Hi Tijmen

Thank you so much for your prompt response.

However, I am not sure this feature (Marker Clusters) is working for me. I enabled it and don’t see a noticeable difference.

Can you please have a look!

Have you tried different values for the “Max zoom”?

This is with level 13Max

This is with level 8Max

They are still not showing in clusters even though I have enabled it in the back-end. I am using the latest version of the plugin

Hmm I wonder what It could be …

I appreciate all your help on this

There are js errors on your site which I should have noticed before, the first one is this, ‘Error: Permission denied to access property ‘document'” followed by one from the cluster marker script. But maybe the first one results in the second error.

From what I found that message has something todo with iframe code. And you do have an iframe on that page, which I think comes from the gravity form plugin.

Could you try to disable the gravity form plugin and see if that makes the cluster markers work?

I have deactivated Gravity forms and also easy fancybox which the form was being called in (lightbox)

still it doesn’t seem to work

I am still seeing some errors in console

Uncaught TypeError: number is not a function markerclusterer.min.js?ver=3.8.5:5

Thank you for your continued support with this!! (y)

That is a different error then before.

Can you try to disable all plugins for a second, except the store locator and see if it works then? Or for a second switch back to the default wp theme? There is a conflict somewhere that breaks it, just not sure where it’s coming from.

Hi Tijmen

I have found out that it was an issue conflicting with the social stream plugin

Do you think I should disable a certain script in this plugin? this plugin is required for the site but we need it to work

i am seeing this error in console:

markerclusterer.min.js?ver=3.8.5:5 Uncaught TypeError: number is not a function

What do you think?

Thank you so so much.. Happy Holidays!!

Switching to another theme for a second and keeping all plugins active and then keeping the marker clusters activated also breaks it?

I installed the social stream plugin as well and enabled the marker clusters, and it did work for me. So maybe it’s a combination with your theme and the social stream plugin?

There is another alternative. The marker cluster js file is minified, so it’s impossible to see on which line it breaks.

If you open the /frontend/class-frontend.php then search for this line, and remove the .min from the file path.

wp_enqueue_script( 'wpsl-cluster', WPSL_URL . 'js/markerclusterer.min.js' );

Then enable the marker clusters again to trigger the error, open the console and you should see a line number. I like to know the line number it says ??

It seems to be working now!

Thank you so much

Removing “.min” from that line was what did the trick!

It’s a bit weird that this fixed it.

As far as I know a minified version is either broken for everyone or it works for everyone. I still think something else on your site caused it to break, but it’s good to hear that it is fixed now!
