검색하기 전에 검색 결과가없고 검색어가 명확하지 않은 Mysql 검색 메시지?

Question

검색 양식을 사용하여 검색 쿼리를 수행 한 후에 결과가 없습니다라는 메시지가 표시되는 데 어려움을 겪고 있습니다. 아래 내 코드. 누군가 도움을 청할 수 있습니까?

예를 들어 3 페이지에있는 경우 검색을 제출 한 다음 내 양식으로 검색을 수행하면 쿼리 문자열을 지울 수 있기를 원합니다. m 이미 3 페이지에 설정되어 있기 때문입니다. 희망은 그 말이 맞습니다.

    switch ($viewstate) { 
     case "open": $where = "status='Open'"; break; 
     case "pending": $where = "status LIKE 'Pending%'"; break; 
     case "closed": $where = "status='Closed'"; break; 
    } 

    $query = "SELECT ticket_number, first_name, surname, email, product, retailer, DATE_FORMAT(dop, '%d %M %Y') AS dop, 
     message, address, DATE_FORMAT(created, '%d %M %Y %r') AS created, status FROM support_dev WHERE $where ORDER BY ticket_number DESC"; 
     $search = "%" . $_POST["search"] . "%";

Answer 1

문자열 내의 문자열과 일치 시키려면 LIKE "%{$search}%"을 사용해야합니다.
