Replace/override your map query settings to showcase diverse locations on any page

In this tutorial, you will learn how to replace/override your existing map query settings with customized ones to showcase different posts or locations on a specific page.

  1. Create a new map #.
  2. Use the PHP code to insert your map inside your taxonomy page #. (e.g. echo do_shortcode('[cspm_main_map id="65"]'); ).
  3. Copy/Paste the following code in the file “functions.php” of your theme/child theme:
/**
 * Override the existing map query settings and display locations based on new custom query args.
 */
function cspm_custom_map_query_settings($map_settings, $map_id, $fields_prefix){

	if(!class_exists('CspmMainMap'))
        return; 
	
	// Specify the page ID and map ID where you want to apply these custom settings
	if(is_page(10) && $map_id == '65'){ // Change the page ID & the map ID  as needed
        
        /**
         * Status
         * ====== */
        
        	$map_settings[$fields_prefix.'_items_status'] = maybe_serialize(array('publish', 'draft')); // Must be SERIALIZED! 
        
        /**
         * Taxonomies
         * ========== */
        
            $taxonomies = array(
                array(
                    'slug' => 'category', // Taxonomy slug
                    'terms_ids' => array(1,2,3), // Taxonomy term(s) ID(s).
                    'operator' => 'IN', // Possible values are 'IN', 'NOT IN', 'AND', 'EXISTS' and 'NOT EXISTS'.
                ),

                $terms_ids = $taxonomy['terms_ids'];

                $map_settings[$fields_prefix . '_'.$slug.'_operator_param'] = $operator;
            }

            if(count($taxonomies) > 1){

Here’s how you can adapt this code to your needs:

  1. Specify the page ID and map ID where you want to apply these custom settings by changing the conditions inside the if statement.
  2. Modify the settings inside the if statement, such as status, taxonomies, custom fields, posts in, posts not in, order, and order by parameters, according to your requirements.
  3. Add or remove taxonomies, custom fields, post IDs, or adjust the order and order by parameters as needed.

Ensure to customize the settings carefully according to your specific use case and requirements. To access comprehensive details regarding WordPress query settings, follow this link.
