Form on a single-post

Hi,

Is it possible to use an S&F form one a single-post page? I want to show results of another post-type, related to the post that’s currently being visited.

To be more specific, I have a post-type for ‘locations’. I want to show all ‘events’ (the other post-type) that are being held at that location. Can it be done?

Hi Kevin, you should be able to do this, but would need to use some PHP filters:

Essentially, you would need to modify the query to show only events from the current page location – you can do that using this filter:

Hi Ross,

Thanks for your answer, I tried to work this out but I’m not getting there yet. I think I’m still confused about what display method I should use for showing results on a single-post. Can you inform me about this?

I’ve solved it with some workarounds. I will post my solution for other people:

Form settings:
– configured the form display method as ‘custom’;
– added a results url of a random page (it needs to be filled);
– enabled Ajax loading and configured a div as Ajax container;
– enabled ‘make searches bookmarkable’;
– enabled Ajax pagination.

I added a filter in functions.php, so the results url for this specific form will always be overwritten with the current permalink:

function filter_function_name( $url,  $sfid) {
	if (get_post_field('post_name', $sfid) == 'agenda-shadow-single-post') {
		$url = get_permalink();
	}
	return $url;
 }
 add_filter( 'sf_results_url', 'filter_function_name', 10, 2 );

I implemented the form in template files as following:

<?php
	// retrieving the the form by using the slug
	$sf_form_obj = get_page_by_path('agenda-shadow-single-post', OBJECT, 'search-filter-widget');

	if ($sf_form_obj) {
		$args['search_filter_id'] = $sf_form_obj->ID;
		$query = new WP_Query($args);

		if ($query->have_posts()) {
			while ($query->have_posts()) {
				$query->the_post();

				get_template_part('template-parts/blocks/block-activiteit');
			}
		} else {
			?>
				<div class='search-filter-results-list' data-search-filter-action='infinite-scroll-end'></div>
			<?php
		}
	}
?>

I tried to alter the query args with the sf_edit_query_args filter, but it didn’t work for me. So I wrote some JavaScript to modify the value of the filter of the post-type that’s currently being viewed. After that I’ve hidden the filter, so it won’t be changed by the user. I did this with a function that’s being triggered on these ajax events:

jQuery(document).on("sf:ajaxstart sf:init sf:ajaxfinish", ".searchandfilter", function () {
	fillFilterOnLocation();
});
