Question

我在url中有一些数据

sub_cat.php S = 1和; OS = 3,1＆安培;品牌= 10,9＆安培;照相机= 19＆安培;存储= 15,13＆安培;数据= 17

我有：

ID为3和1的操作系统
ID为10和9的品牌
ID为19的相机
存储ID为id 15和13
数据为id 17

我想从sql数据库

显示具有这些规范的手机

if (isset($_GET['brand'])) {
          $sf_brand = $_GET['brand'];
          $brand_split = explode(',', $sf_brand);
          $sf_brand_len = count($brand_split);
          for ($ab=0; $ab < $sf_brand_len; $ab++) { 
            $append_sf_brand .= 'OR product.product_brand LIKE \''.$brand_split[$ab].'\' ';
          }
          $append_sf_brand_f = '('.substr($append_sf_brand, 3).')';
        }else{
          $append_sf_brand_f = '';
        }
        if (isset($_GET['os'])) {

          $os_split = explode(',', $sf_os);
          $sf_os_len = count($os_split);
          for ($ao=0; $ao < $sf_os_len; $ao++) { 
            $append_sf_os .= 'OR productspec.prospec_expspec_id LIKE \''.$os_split[$ao].'\' ';
          }
          $append_sf_os_f = '('.substr($append_sf_os, 3).')';
        }else{
          $append_sf_os_f = '';
        }
        if (isset($_GET['camera'])) {
          $sf_camera = $_GET['camera'];
          $camera_split = explode(',', $sf_camera);
          $sf_camera_len = count($camera_split);

          }
          $append_sf_camera_f = '('.substr($append_sf_camera, 3).')';
        }else{
          $append_sf_camera_f = '';
        }
        if (isset($_GET['data'])) {
          $sf_data = $_GET['data'];
          $data_split = explode(',', $sf_data);
          $sf_data_len = count($data_split);
          for ($ad=0; $ad < $sf_data_len; $ad++) { 
            $append_sf_data .= 'OR productspec.prospec_expspec_id LIKE \''.$data_split[$ad].'\' ';
          }
          $append_sf_data_f = '('.substr($append_sf_data, 3).')';
        }else{
          $append_sf_data_f = '';
        }
        if (isset($_GET['storage'])) {
          $sf_storage = $_GET['storage'];
          $storage_split = explode(',', $sf_storage);
          $sf_storage_len = count($storage_split);
          for ($as=0; $as < $sf_storage_len; $as++) { 
            $append_sf_storage .= 'OR productspec.prospec_expspec_id LIKE \''.$storage_split[$as].'\' ';
          }
          $append_sf_storage_f = '('.substr($append_sf_storage, 3).')';
        }else{
          $append_sf_storage_f = '';
        }
        $sf_condition = '(product.product_id LIKE productspec.prospec_product_id) AND '.$append_sf_brand_f.' AND '.$append_sf_os_f.' AND '.$append_sf_camera_f.' AND '.$append_sf_data_f.' AND '.$append_sf_storage_f;

我有疑问：

$get_brand_query = mysqli_query($connect, "SELECT * FROM product, productspec WHERE $sf_condition");

但它运作不佳，所以我可以展示手机，任何人都可以帮助我。
