이전 포스팅에서 테이블 구조는 보여주었다.

 

 

이번엔 미리 등록해둔 데이터 정보 중 원하는 데이터를 불러오려고 한다.

 

 

우선 마찬가지로 php코드를 작성해준다.

cafe_info.php

          cafe name: <input type = "text" name = "name" />
 
         <input type = "submit" />
      </form>
 
   </body>
</html>
<?php
}
 
 
?>
 

 

 

웹브라우저에 http://localhost:포트번호/Login.php 실행하면 이렇게 뜬다.

 

 

카페 이름을 입력하면 카페 정보를 가져온다.

 

 

 

안드로이드로 옮기기 위해서 레이아웃 코드를 작성한다.
