PHP Codeigniter Recherche avancée Filtre

Question

Je suis en train d'écrire une requête de recherche avancée en utilisant Codeigniter Query Builder mais il donne des résultats erronés. J'ai 3 tables de base de données (vehicles, vehicle_pictures, date_ranges) d'où j'obtiens les résultats. Le tableau date_ranges contient des dates non disponibles pour chaque véhicule et il peut y avoir une ou plusieurs dates d'indisponibilité pour chaque véhicule, je veux savoir si cette approche est bonne? et quel est le problème avec ma requête. Voici une image et un code de mes filtres. Picture of Filters

public function get_results() { 
    $location = strip_tags($this->input->get('location')); 
    $location = explode(',', $location ? $location : ''); 
    $pickup = $this->input->get('pickup'); 
    $dropoff = $this->input->get('dropoff'); 
    $min_price = $this->input->get('min_price'); 
    $max_price = $this->input->get('max_price'); 
    $types = $this->input->get('types') ? $this->input->get('types') : []; 
    $travelers = $this->input->get('people'); 
    $min_year = $this->input->get('min_year'); 
    $max_year = $this->input->get('max_year'); 
    $min_length = $this->input->get('min_length'); 
    $max_length = $this->input->get('max_length'); 

    $select = ['vehicles.id', 'vehicles.year', 'vehicles.model', 'vehicles.nightly_rate', 'vehicles.class', 'vehicle_pictures.picture', 'vehicles.people']; 
    $this->db->select($select);

     } 
    } 

    if (!empty($pickup) && !empty($dropoff)) { 
     $d1 = date('Y-m-d', strtotime($pickup)); 
     $d2 = date('Y-m-d', strtotime($dropoff));
