Modify URL Structure

Shelley BBShelley BB asked 2 months ago
Hi Guys I'm using a number of different types of views and I need to modify the URL structure into a more SEO friendly format. Is this possible WITHOUT generating posts from entries? Example: I have a side-by-side comparison feature that displays a grid of form entries with a compare checkbox in each. The entries are cameras and accompanying specifications.

I have a second view that displays the comparison results after the compare button is clicked and this all works as expected.

The URLs display with the query parameters like this: /camera-comparison/?compare[]=1000&compare[]=1001

I need them to display like this: /camera-comparison/camera-name-vs-camera-name (camera name can be the entry key if needed)

I also need the canonical URL in the above friendly format.

I've read the docs but can't find anything for this use case. Is this possible?

I managed to create a solution and have added the code below in case anyone else wants to do this.

// Custom rewrite rules for comparison
function custom_rewrite_rules() {
add_action('init', 'custom_rewrite_rules');

// Add compare to query vars
function custom_query_vars($vars) {
$vars[] = 'compare';
return $vars;
add_filter('query_vars', 'custom_query_vars');

// Parse the compare query var into an array
function parse_compare_query_var($query) {
if (!is_admin() && $query->is_main_query() && $query->is_page('compare')) {
$compare = $query->get('compare');
if ($compare && !is_array($compare)) {
$query->set('compare', explode('-vs-', $compare));
add_action('pre_get_posts', 'parse_compare_query_var');

// Remove the default canonical URL
remove_action('wp_head', 'rel_canonical');

// Add custom canonical URL
function add_canonical_url() {
if (is_page('compare')) {
$compare = get_query_var('compare');

if ($compare) {
// Ensure $compare is an array
if (!is_array($compare)) {
$compare = array($compare);

// Filter out empty values
$compare = array_filter($compare);

// Generate the canonical URL
$canonical_url = home_url('/compare/' . implode('-vs-', $compare));
echo '<link rel="canonical" href="' . esc_url($canonical_url) . '" />';
add_action('wp_head', 'add_canonical_url');


document.addEventListener('DOMContentLoaded', function () {
const params = new URLSearchParams(;
const compare = params.getAll('compare[]');

if (compare.length > 0) {
// Generate the clean URL with the new page name
const cleanUrl = '/compare/' + compare.join('-vs-');

// Update the URL in the browser without reloading the page
window.history.replaceState({}, document.title, cleanUrl);

Let me see if I understand you correctly. You want to filter a view without using a query string to pass parameters? Is that correct?

I'm not sure if that's the correct description. The views are based are selections by the user so it is a query, I just want to change how the URL of the resulting view is displayed.

When you pass parameters to a view filter, you have to use a Query string. I don't know of a work around to this. This is how view filters work. There is the frm-set-get shortcode that will set filter values, but you sitill need to pass the values through a query string.

You may be able to customize something with AJAX or REST that works outside of Formidable's structure to do what you want, but that would require a project engagement because you want to do something Formidable is not designed to do.

<p>Would that involve messing with the filters/queries themselves, or just how the URL is displayed? I don't want to compromise the stability of the application. Thanks!</p>

I have no idea what it would take. You're the first person to ever ask this question.
