[Resolved] How to pass URL parameter to the view for filtering

Tell us what you are trying to do?

I have created a view and some filters.
I have a custom date field and I want to provide users a dropdown select to filter "past posts" or "upcoming posts" (based on my custom date and today).

I found in similar questions that I should use "wpv_filter_query". My problem is that I cannot pass the value of selected dropdown as a param to catch it later in "wpv_filter_query".
Here is the select inside the [wpv-filter-controls]:

<select class="js-wpv-filter-trigger form-control" name="date-check">
<option value="" selected>-- All --</option>
<option value="past posts">past posts</option>
<option value="upcoming posts">upcoming posts</option>
</select>

Is there any documentation that you are following?

https://toolset.com/documentation/user-guides/views-filters/#wpv_filter_query

Is there a similar example that we can see?

What is the link to your site?
I can provide you if needed

Hi, you should be able to find the selected option value in the $_GET superglobal with the key 'date-check'. Here's an example:

add_filter( 'wpv_filter_query', 'extra_filtration', 10, 3 );
function extra_filtration ( $query, $view_settings, $view_id ) {
  $views = array( 123, 456, 83 );
  if( in_array( $view_id, $views) ) {
    // uncomment next line to dump everything in $_GET to the logs
    // error_log( print_r( $_GET, true) );
    $date_check = $_GET['date-check']; // $date_check now equals "upcoming posts" or "past posts" or ""
    error_log('date check: ' . $date_check );
    // do $query manipulation here
  }
 return $query;
}

Change 123, 456 to be a comma-separated list of View IDs where you want to apply this filter.

Hi Christian, thank you for your response but my problem is when I hit search button the 'date-check' is not passed on URL hence $_GET['date-check'] is null in `wpv_filter_query`.
Thanks

Can you tell me more about this View?
- Are you using AJAX for search or for pagination? If you disable AJAX, can you find the generic search field in $_GET?
- Is the advanced search option "Only show available options for each input" turned on?
- Are any other URL parameters passed into the $_GET superglobal correctly by other filters?
- Are the search filters and search results displayed on separate pages, or the same page?
- Have you inserted the View using separate blocks in the block editor, or separate shortcodes in the classic editor?
- Can I see the View on your live site somewhere? If so, please provide a URL.
