선택 목록의 값을 간단한 형식으로 전달할 수 없습니까?

Question

하나의 선택 목록이있는 간단한 CRUD 양식을 작성했습니다. 그러나 선택 목록의 값은 데이터베이스로 전달되지 않습니다. 그것은 간단한 텍스트 상자를 사용할 때 전달됩니다. 가능한 오류가 무엇입니까? 제발 지적하십시오

<?php 
include('config.php'); 
if (isset($_POST['submitted'])) { 
foreach($_POST AS $key => $value) { $_POST[$key] = mysql_real_escape_string($value); }

Answer 1

당신은 공백이 허용되는 문자가 아닙니다.

name="course_detail" isnstead.

Answer 2

오류나 경고가 발생 했습니까? print_r($_POST)으로 POST 배열을 출력하려고 시도 했습니까? 또한, value="" 속성을 옵션 태그에 넣으십시오.
