Automatically apply a map filter using a URL or Query String

[incredibleediblelambeth]

Hi,

Does anyone know if it is possible to apply a filter to a map using the page URL.

For example,
I have a map with multiple POIs with different categories e.g. cat_1, cat_2, cat_3
It has filters set up using the categories: cat_1, cat_2, cat_3
Pins can be filtered using the build in Filters in the UI

My question is can I apply a filter automatically using the URL. e.g. http://www.mywebsite/map?filter=cat_3
I can then link to the map and have a filter applied automatically.

I expect I can do something like this using https://developer.wordpress.org/reference/functions/get_query_var/ and call a filter function on the map.

Has anyone done anything like this?

Any help much appreciated.

Hi,

You should be able to do this for mashups using the [mashup] shortcode. There are some examples in the plugin documentation. You can use variables in the mashup query to indicate WordPress query variables, such as categories.

Thanks for your help.

I have tried that and it works for a single filter. But once I have done that I can’t use the filters on the map on the front end.

To give you more context…

My setup:
– I have a Mashup map displaying all ‘location’ posts (custom posts)
– I have a ‘location_type’ custom taxonomy set on ‘location’ posts
– My map has a filter setup in the MapPress plugin settings using location_types as check boxes
– I can filter the locations posts using the map filter UI on the location_types – this is all working really well

What I’d like to do is:
– apply a filter to the map from the URL
– see the filter appplied to the map on the filter UI
– change the map filter using the filter UI to a different filter

This is where I am at:

I am using a URL /map/?location_type=cafe-shop

my PHP is

if ( get_query_var('location_type') ) {
	$filter = get_query_var('location_type');			
	echo do_shortcode('[mashup query="post_type=location&location_type=' . $filter. '"]'); 
}

The map filters by ‘cafe-shop’ as expected.

Issues:
– The filter list on the UI does not have ‘cafe-shop’ selected
– If I try to change the filter to something else usising the UI, the filter does not work, it stays on ‘cafe-shop’

Is there a way of pre-filtering the map and then allowing the user to interact with the filters?

Thanks
