Remove only certain URL parameters after filtering

This thread is resolved. Here is a description of the problem and solution.

Problem:

The customer wanted to filter a view on their website so that only specific URL parameters, such as "category=blog," remain visible in the URL after filtering. By default, all parameters were displayed, which cluttered the URL with unnecessary information.

Solution:

A combination of PHP and JavaScript was used to selectively retain only the category parameter in the URL after filtering. Here’s the implemented approach:

1- A hidden field was added to capture and maintain the category parameter, using a custom function in the theme’s functions.php file:

add_filter('wpv_filter_end_filter_form', 'add_hidden_category_param', 99, 4);
function add_hidden_category_param($out, $view_settings, $view_id, $is_required) {
    $views = array(12345); // Replace with the View ID
    if (in_array($view_id, $views) && $is_required) {
        $category = isset($_GET['category']) ? $_GET['category'] : '';
        $out = '<input type="hidden" id="category" name="category" value="' . esc_attr($category) . '" />' . $out;
    }
    return $out;
}

This function captures the category parameter and stores it in a hidden input field to ensure it persists through the filter updates.

2- In the View's Custom JavaScript section, this code was added to ensure only the category parameter remains visible in the URL

jQuery(document).ready(function($) {
    $(document).on('js_event_wpv_parametric_search_form_updated', function(event, data) {
        var url = new URL(window.location);
        var category = url.searchParams.get("category");
        jQuery('#category').val(category); // Update hidden input field with the category parameter

        // Update the URL to show only the category parameter
        let params = new URLSearchParams({ category: category });
        window.history.replaceState({}, '', `${url.pathname}?${params.toString()}`);
    });
});

This JavaScript ensures the URL updates to include only the category parameter after filtering, creating a cleaner URL.

Hi,

When I filter my view, i get a bunch of parameters in my URL, like this:

hidden link

I know I can choose to remove all URL parameters in the view settings, but i'd like to only show the ones that specify a category, in this instance the last one: "category=blog". So the URL would be : hidden link

Is there a way for me to achieve this, or is it all or nothing?

Thank you

Hi Eric,

Thanks for reaching out!

I believe it is possible to keep the 'category' parameter in the URL and remove the others when filtering.

To do this, we can use a combination of PHP and JavaScript similar to the approach used in this thread : https://toolset.com/forums/topic/preserve-query-string-on-ajax-search:

1. Add a Hidden Field for the Category Parameter: This code will capture and keep only the 'category' parameter in the URL. Add it to your theme’s 'functions.php' file:

   add_filter( 'wpv_filter_end_filter_form', 'add_hidden_category_param', 99, 4 );
   function add_hidden_category_param( $out, $view_settings, $view_id, $is_required ) {
       $views = array( 12345 ); // Replace 12345 with your View ID
       if ( in_array( $view_id, $views ) && $is_required ) {
           $category = isset($_GET['category']) ? $_GET['category'] : '';
           $out = '<input type="hidden" id="category" name="category" value="' . esc_attr($category) . '" />' . $out;
       }
       return $out;
   }

2. JavaScript to Update the URL with Only the Category Parameter: In the View's Custom JS section, add this to keep just the `category` parameter when filters update:

   jQuery(document).ready(function($) {
       $(document).on('js_event_wpv_parametric_search_form_updated', function(event, data) {
           var url = new URL(window.location);
           var category = url.searchParams.get("category");
           jQuery('#category').val(category); // Update hidden input field with the category parameter

           // Update the URL to show only the category parameter
           let params = new URLSearchParams({ category: category });
           window.history.replaceState({}, '', `${url.pathname}?${params.toString()}`);
       });
   });

This will ensure only the `category` parameter shows in the URL after filtering, while Toolset's default parameters remain hidden. Please take a look at the thread for more reference and give it a try.

Best,
Mateus
