'<br><b> house type:</b>  ' . $house_type;      $query = "insert `house_names` (`id`, `name`) values (null, '$house_name')";     $result = $conn->query($query);     if (!$result) die ("<b class='text-danger'><p>insert failed errror: " . $conn->error. "</p>");      global $house_name_id;     $house_name_id = $conn->insert_id;     $query = "insert `house_types` values ('$house_name_id', '$house_type')";     $result = $conn->query($query);     if (!$result) die ("<b class='text-danger'><p>insert failed errror: " . $conn->error. "</p>");     } else {     global $house_name_id;     $house_name_id= null;     }    //start container page content echo '<div class="container">';  //display error message if house name filled in not house type if ( !empty($_post['h_name']) && empty($_post['h_type']) || empty($_post['h_name']) && !empty($_post['h_type']) ) {     echo "<p class='error-text'>* please fill in both house name , house type *</p>"; }     $query_feat = $conn->query('select * features'); $rows = $query_feat->num_rows;   $features_list  = $_post['check_list']; $feature_id = $_post['feature_id']; //display checked boxes. if(isset($_post['check_list'])) {     ($i=0; $i<sizeof($features_list); $i++){          //echo '<br>house name id:' . $house_name_id . '<br> $_post[] = ' . "$features_list[]";         print_r($features_list); echo '<br>';         print_r($feature_id);     } }     // add house form echo <<<_end       <h1>add house</h1> </div> <div class="container">     <form action="add.php" method="post">         <p>house name: <input type="text" name="h_name"></p>         <p>house type: <input type="text" name="h_type"></p>         <b>features:</b>          <ul class="list-group"> _end;         ($c = 0 ; $c < $rows ; ++$c){          $query_feat->data_seek($c);         $feat = $query_feat->fetch_array(mysqli_num);           echo '<li><input type="checkbox" name="check_list[]" value="' .$feat[1]. '">'.$feat[1].'</li>';  }   echo <<<_end         <ul>         <input class="btn-primary" type="submit" value="submit">     </form> </div>  _end;    require_once 'footer.php';

change value of checkbox id or want.

<li><input type="checkbox" name="check_list[]" value="' .$feat[0]. '">'.$feat[1].'</li>


$feat[1] => $feat[0] or else
