在一張桌子上的數據庫php多個輸入搜索表單

Question

我創建搜索表單，它的工作原理正確，但我想添加另一個字段用於搜索數據庫中任意列的一個字母。

這

我要添加查詢：

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)); 

這個圖像解釋的形式：

這是我用的搜索代碼：

if(isset($_POST['submit'])) { 
     $RelatedCustome=$_POST['txt_RelatedCustomer']; 
     $LevelofPriority=$_POST['txt_LevelofPriority']; 
     $category=$_POST['txt_category']; 
     $subcategories=$_POST['txt_subcategories']; 
     $ProductOrService=$_POST['txt_ProductOrService']; 
     $CompanyName=$_POST['txt_CompanyName']; 
     $Namecontactperson=$_POST['txt_Namecontactperson']; 
     $evaluation=$_POST['txt_evaluation']; 
     $search=$_POST['txt_search']; 


    $q = array(); 
     $sql = ""; 
     if(isset($_POST['txt_RelatedCustomer']) && !empty($_POST['txt_RelatedCustomer'])){ 
     $RelatedCustome = mysqli_real_escape_string($conn,$_POST['txt_RelatedCustomer']); 
     $q[] = " db_RelatedCustome='".$RelatedCustome."' ";  
     } 
     if(isset($_POST['txt_LevelofPriority']) && !empty($_POST['txt_LevelofPriority'])){ 
     $LevelofPriority = mysqli_real_escape_string($conn,$_POST['txt_LevelofPriority']); 
     $q[] = " db_LevelofPriority='".$LevelofPriority."' ";  
     } 
      if(isset($_POST['txt_category']) && !empty($_POST['txt_category'])){ 
      $category = mysqli_real_escape_string($conn,$_POST['txt_category']); 
     $q[] = " db_Category='".$category."' ";  
     } 
      if(isset($_POST['txt_subcategories']) && !empty($_POST['txt_subcategories'])){ 
      $subcategories = mysqli_real_escape_string($conn,$_POST['txt_subcategories']); 
     $q[] = " db_Subcategories='".$subcategories."' ";  
     } 
      if(isset($_POST['txt_ProductOrService']) && !empty($_POST['txt_ProductOrService'])){ 
     $ProductOrService = mysqli_real_escape_string($conn,$_POST['txt_ProductOrService']);    
     $q[] = " db_ProductOrService='".$ProductOrService."' ";  
     } 
      if(isset($_POST['txt_CompanyName']) && !empty($_POST['txt_CompanyName'])){ 
      $CompanyName = mysqli_real_escape_string($conn,$_POST['txt_CompanyName']); 
     $q[] = " db_CompanyName='".$CompanyName."' ";  
     } 
      if(isset($_POST['txt_Namecontactperson']) && !empty($_POST['txt_Namecontactperson'])){ 
      $Namecontactperson = mysqli_real_escape_string($conn,$_POST['txt_Namecontactperson']); 
     $q[] = "db_Namecontactperson='".$Namecontactperson."' ";  
     } 
      if(isset($_POST['txt_evaluation']) && !empty($_POST['txt_evaluation'])){ 
      $evaluation = mysqli_real_escape_string($conn,$_POST['txt_evaluation']); 
     $q[] = "db_evaluation='".$evaluation."' ";  
     } 

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


     $result=mysqli_query($conn,"SELECT * FROM tbl_subcontractor {$sql}")or die(mysqli_error($conn)); 
     $count=mysqli_num_rows($result);

如何混合用我的代碼查詢以獲得完美的結果。

Answer 1

我找到了解決辦法，這是謝你爲你的時間你給我的解決方案的想法

$qq=array(); 
      if(isset($_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

在所有您的Q陣列，你應該使用「％」這樣的

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

和這部分代碼更改爲

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