php多个输入搜索表单在一个表databe上

我创建搜索表单并且它完全正常工作但我想在数据库的任何列中添加另一个字段来搜索字母。

这是我要添加的查询：

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));

此图片解释表格：

这是我用于搜索的代码：

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'])){

        }

如何将查询与我的代码混合以获得完美的结果。

在所有你的q数组中，你应该像这样使用'％'

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

并将此部分代码更改为

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

我找到了解决方案，感谢您抽出时间给我解决方案的想法 

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