// Assign players to match
function assign_players_to_match($match_id, $team_ids) {
    if (count($team_ids) < 2) {
        return;
    }

    $team_1_id = $team_ids[0];
    $team_2_id = $team_ids[1];

    // Clear current players
    delete_post_meta($match_id, 'sp_player');

    // Add players to team 1
    $team_1_players = get_players_by_team_id($team_1_id);
    foreach ($team_1_players as $player_id) {
        add_post_meta($match_id, 'sp_player', $player_id, false);
    }

    // Clear players from team 2 again
    delete_post_meta($match_id, 'sp_player');

    // Add players to team 2
    $team_2_players = get_players_by_team_id($team_2_id);
    foreach ($team_2_players as $player_id) {
        add_post_meta($match_id, 'sp_player', $player_id, false);
    }
}

function get_players_by_team_id($team_id) {
    $args = array(
        'post_type' => 'sp_player',
        'posts_per_page' => -1,
        'post_status' => 'publish',
        'fields' => 'ids',

            array(
                'key' => 'sp_current_team',
                'value' => $team_id,
                'compare' => '=',
            ),
