PHP에서 적어도 하나의 체크 박스가 선택되어 있는지 확인하십시오.

Question

"이미 적어도 하나의 체크 박스가 PHP에 체크되어 있는지 확인하십시오"라는 질문을 발견했지만, 필자는 조직적인 사람이고 그렇지 않았기 때문에 내 요구를 충족시키지 못했습니다. 그것을하는 조직 된 방법처럼 보입니다. 나는이 체크 박스 코드가 있습니다

형태가 페이지라는 validation.php에 제출하고이 해당 페이지에 대한 코드입니다 (I 거의 아직 아무것도 없다) :

이

<?php 
     $lastname = $_REQUEST["lastname"]; 

     $firstname = $_REQUEST["firstname"]; 

     $company = $_REQUEST["company"]; 

     $accttype = $_REQUEST["accttype"]; 

     $productname = $_REQUEST["productname"]; 

     $sharetype = $_REQUEST["sharetype"]; 

     $closed = $_REQUEST["closed"]; 

     $valuegreaterthan = $_REQUEST["valuegreaterthan"]; 
     header("Location: http://www.its-a-secret/?lastname=" . htmlspecialchars($lastname) . "&firstname=" . htmlspecialchars($firstname) . "&company=" . htmlspecialchars($company)); 
    ?> 

싶습니다에 HTML 특수 문자를 변경하지 말고 삭제하십시오. 사용자에게 말하여 대문자를 하나만 갖기를 원합니다. 만약 그들이 SQL을 사용하여 유효성을 검사하기를 원한다면 이름이나 성이 모두 자본이거나 그런 미친 짓이야. 또한 성 (姓)과 성 (姓)이 있으면 거기에 모든 공간이 있어야합니다. 적어도 하나의 확인란을 선택해야합니다. 또한 숫자 텍스트 상자에 숫자 인 양수가 있어야합니다.

Answer 1

나는 당신이 뭘 하려는지 모르겠지만, 여기에 내 생각 엔 코드 :이 도움이 될 수

if(isset($_GET['showcolumnxx']) || isset($_GET['showcolumnxx']) || isset($_GET['showcolumnxx'] || etc.)) { 
    $newUrl = "http://something.site.end/otherpageshere/[screenAfterValidation].php"; 
    header('Location: ' . $newUrl); 
    } else { 
     print "<p style = "color: red;">You must at least check one checkbox.</p>\n"; 

    } 

Answer 2

은. 나는 단지 같은 페이지에 울리고있다. 필요에 따라 변경할 수 있습니다. 체크 박스 중 하나가 게시 된 경우

if(!empty($_GET['check'])) { 
    foreach($_GET['check'] as $check) {

    }
