하나의 테이블에 PHP 다중 입력 검색 양식

Question

검색 양식을 만들고 정확하게 작동하지만 데이터베이스의 모든 열에있는 문자를 검색하기위한 다른 필드를 추가하고 싶습니다.

이것은 내가 추가 할 쿼리

if(isset($_POST['submit'])) { 
     $RelatedCustome=$_POST['txt_RelatedCustomer']; 
     $LevelofPriority=$_POST['txt_LevelofPriority'];

이 내가 검색에 사용되는 코드는 다음과 같습니다

mysqli_query($conn,"SELECT * FROM tbl_subcontractor where db_RelatedCustome like '%$search%' or db_LevelofPriority like '%$search%' or db_Category like '%$search%' or db_Subcategories like '%$search%' or db_ProductOrService like '%$search%' or db_CompanyName like '%$search%' or db_Namecontactperson like '%$search%' or db_evaluation like '%$search%' ")or die(mysqli_error($conn));

어떻게 혼합 할 수 있습니까? 완벽한 결과를 얻으려면 내 코드로 쿼리하십시오.

Answer 1

내가 해결책을 발견 에 코드의이 부분을 변경하고이 감사입니다 당신은 나에게 그 해결책에 대한 아이디어를 내게 주겠다.

$qq=array(); 
      if(isset($_POST['txt_search']) && !empty($_POST['txt_search'])){ 
      $search = mysqli_real_escape_string($conn,$_POST['txt_search']); 
     $qq[] = "db_evaluation like '%".$search."%' "; 
     $qq[] = "db_Namecontactperson like '%".$search."%' "; 
     $qq[] = " db_CompanyName like '%".$search."%' "; 
     $qq[] = " db_ProductOrService like '%".$search."%' "; 
     $qq[] = " db_Subcategories like '%".$search."%' "; 
     $qq[] = " db_Category like '%".$search."%' "; 
     $qq[] = " db_LevelofPriority like '%".$search."%' "; 
     $qq[] = " db_RelatedCustome like '%".$search."%' "; 
     } 
    foreach($qq as $qu){ 
      if($second){ 
      $sql .= " where ".$qu;  
      $second = false; 
      }else{ 
      $sql .= " or ".$qu;   
      } 
     } 

Answer 2

에서 모든 당신의 질문의 배열이

$q[] = "db_evaluation='%".$search."%'"; 

처럼 사용 '%'를해야하며,

$first = true; 
foreach($q as $qu){ 
    if($first){ 
    $sql .= " where ".$qu;  
    $first = false; 
    }else{ 
    $sql .= " or ".$qu;   
    } 
}
