Updating search data via AJAX not returning anything

#173536

I have a filter form that automatically submits as the user selects filter parameters, and displays loads via AJAX. That’s working fine but I can’t seem to get the search data to return the correct values when the search results update.

I would like to output something like this:

Travel Month: January
Destinations: Grand Canyon, Las Vegas
Activities: Great for Kids, Photography

Here is my JS script:

(function($){
	$(document).on("sf:ajaxfinish", ".searchandfilter", function(){
		console.log("ajax complete");
		$.ajax({
		    type: "POST",
		    url: "/wp-admin/admin-ajax.php",
		    data: { action: 'filterParams'}
		}).done(function( response ) {
		    $( ".parameters" ).html( response );
		});	 
	});    
})(jQuery);

And here is the PHP script that I put in functions.php:

function filterParams(){
    global $searchandfilter;
	$sf_current_query = $searchandfilter->get(12192)->current_query();
	$args = array(
		"str" 					=> '%1$s: %2$s', // this is the format of the string generated for each field
		"delim" 				=> array(", ", " - "), 
		"field_delim"			=> '<br />',
		"show_all_if_empty"		=> true
	);
	
	echo $sf_current_query->get_fields_html(
		array("_sft_travelmonth","_sft_destination", "_sft_activities"), 
		$args
	);
}
add_action('wp_ajax_filterParams', 'filterParams');
add_action('wp_ajax_nopriv_filterParams', 'filterParams');

This is what is always getting returned in the AJAX call:

Travel Months: All Travel Months
Destinations: All Destinations
Activities: All Activities0

When I use:
var_dump($sf_current_query->get_array());
instead of:

echo $sf_current_query->get_fields_html(
    array("_sft_travelmonth","_sft_destination", "_sft_activities"), 
    $args
);

It returns an empty array:
array(0) { } 0

I’ve confirmed that the form ID is correct.
What am I missing here?

Ok, turns out I was way overengineering this. The simple solution is to put he PHP block INSIDE the element that the AJAX results load into. Like this:

<div  id="ajax-results">
<?php

	global $searchandfilter;
	$sf_current_query = $searchandfilter->get(12192)->current_query();
	echo $sf_current_query->get_fields_html(
		array("_sft_travelmonth","_sft_destination", "_sft_activities"), 
		$args
	);
?>
