사용자가 잘못된 코드를 입력하면 메시지가 표시되지 않습니다.

Question

올바른 쿠폰 코드를 입력 할 때 사용자가 광고를 제출하고 업데이트 할 수있는 양식을 만들었지 만 "잘못된 쿠폰 코드"라는 메시지가 표시되지 않습니다. 그들이 잘못된 쿠폰 코드를 입력하면 에코 아웃합니다.

을 heres 내 코드 :

while ($row = mysql_fetch_assoc ($query)) 
{ 
    //retrieve code from database to match with the code that was put into field 
    $dbcode = $row['code']; 
} 

코드의이 블록은 모든 코드를 수집하지 않습니다. 모든 코드에 $ dbcode를 덮어 쓰는 것뿐입니다. 블록의 끝에는 마지막 행만 있습니다.

나머지 코드는이 블록 안에 있어야한다고 가정합니다. 이
