无法在数据库中添加多行

Question

我想将多个家庭成员详细信息放在数据库中 但是插件不起作用，并且没有显示任何错误。

我已经尝试过：<input type="text" name="family_member_first_name[]" class="form-control"/>但它没有用。

PHP：

if (isset($_POST["submit4"])) {
    if ($_SESSION['email']) {
        $db->where('primary_email', $_SESSION['email']);
        $email_fetch_femily = $db->getone('om_user_list_a');
        if ($email_fetch_femily) {
            $fetch_id_family = $email_fetch_femily['id'];
        }

        $status = 1;
        $c_by   = 1;
        $c_date = date('Y-m-d H:i:s');
        $c_ip   = $_SERVER['REMOTE_ADDR'];

        $row = $_POST['num'];

        for ($i = 0; $i < $row; $i++) {
            $insert_family_details = $mysqli->query("INSERT into `om_relative_list` (`user_id`,`first_name`,`middle_name`,`last_name`,`birth_date`,`relative_type`,`marital_status`,`education_status`,`occupation`,`phone`,`gratuity_ratio`,`nomination_ratio`,`status`,`created_by`,`created_date`,`created_ip`) values ('$fetch_id_family','" . $_POST['family_member_first_name'][$i] . "','" . $_POST['family_member_middle_name'][$i] . "','" . $_POST['family_member_last_name'][$i] . "','" . $_POST['family_member_birth_date'][$i] . "','" . $_POST['family_member_relation'][$i] . "','" . $_POST['family_member_merital_status'][$i] . "','" . $_POST['family_member_education'][$i] . "','" . $_POST['family_member_occupation'][$i] . "','" . $_POST['family_member_phone'][$i] . "','" . $_POST['family_member_gratuity_ratio'][$i] . "','" . $_POST['family_member_nomination_ratio'][$i] . "','$status','$c_by','$c_date','$c_ip')");
        }

        if ($insert_family_details) {
            echo "<script>alert('family details insert successfully');</script>";
        } else {
            echo "<script>alert('!!!!family deatis insert unsuccessfully');</script>";
        }
    }
}
