actually it looks like registration is the same, and I had made some wrong assumptions! in any case, thanks!

I think this is handling a single field at a time, rather than giving me a $_POST I can work with, so I can’t do exactly the same process. That said, I can make this work. Thanks!

I should add that I am using some forms as a UI for the end user to control these filters. So what I really want to know is, what is the best practice for providing the user’s input to the bp ajax handler and passing it through to my filter?

I also want to have that data available when I am emitting the form so I can persist the selected options.

I am currently displaying the form via a function in a BP_Group_Extension class. Here’s the function that provides it:

  public function display_group_filters($raw_filters = []) {
    $sl = [];
    $tf_semester = [];
    $tf_year = [];
    if(!empty($raw_filters['student_level'])){
      $sl = $raw_filters['student_level'];
    }

    if(!empty($raw_filters['semester'])){
      $tf_semester = $raw_filters['semester'];
    }
    if(!empty($raw_filters['year'])){
      $tf_year = $raw_filters['year'];
    }

    $out = '
    <div id="group-dir-filter"
      class="col-xs-12 col-md-3 col-md-pull-9" role="filter">
      <form action="" method="get" id="filters">
        <h3>Filters</h3>
        <p>
        Use the controls below to limit what projects are shown.
        </p>
        <div class="filter-section col-xs-6 col-md-12">
          <h4>Student level</h4>';
    $out .= $this->student_levels_markup($sl, false);
    $out .= '
        </div>
        <div class="filter-section col-xs-6 col-md-12">
          <h4>Timeframe</h4>';
    $out .= $this->semester_markup($tf_semester, $tf_year, false);
    $out .= '
        </div>
        <input type="hidden" name="action" value="tp_filter_group" />
        <button class="btn btn-warning" type="button"
        onclick="window.location.href=\''.esc_url( home_url( '/' ) ).'/groups\'" />Reset</button>
        <button type="submit" class="btn btn-info">Filter</button>
      </form>
    </div>';
    echo $out;
    return $out;
  }
