Topic Tag: Custom search

Problem: I have a custom search View with several search fields placed on a page. Only the search form, not the results, are shown on the page. The View is set up to redirect to a different URL, where the filters and results are both displayed. When Users visit the first page, the URL will have a parameter "promocode" with some variable. When the page redirects to the next step, I want to maintain the original URL parameter on the results page.

Solution: Use the View filter "wpv_filter_end_filter_form" to add a hidden input field to the custom search form, and set the value of the field by accessing the URL parameter in the $_GET superglobal:

add_filter( 'wpv_filter_end_filter_form', 'prefix_add_hidden_field', 99, 4 );
function prefix_add_hidden_field( $out, $view_settings, $view_id, $is_required ) {
    $views = array( 16855 );
    if ( in_array( $view_id, $views) && $is_required ) {
      $promocode = isset($_GET['promocode']) ? $_GET['promocode'] : '';
      $out = '<input type="hidden" id="promocode" name="promocode" value="' . $promocode . '" />' . $out;
    }
    return $out;
};

Then if your View is set up to "only show available inputs" you'll need to add some custom JavaScript to update the hidden promocode field any time the filters are updated:

jQuery( document ).on( 'js_event_wpv_parametric_search_form_updated', function( event, data ) {
    var url = new URL(window.location);
    var promocode = url.searchParams.get("promocode");
    jQuery('#promocode').val(promocode);
});

Problem:
Doubt with wpv-search-term shortcode and multiple checkboxes parameter

Solution:
You can use view's shortcode [wpv-search-term] to display the values of URL params.

For example:

[wpv-search-term param='wpv-wpcf-district']
