在php mysql pdo中显示多个插入图像中的一个图像

Question

我的问题是我想只显示主页上传的多张图片中的一张图片，并在另一页上显示所有图片。
     代码的第一部分用于完美的多重上传，代码的第二部分用于选择。但图像没有显示。

$file_name_all="";
        for($i=0; $i<count($_FILES['image']['name']); $i++) 
        {
            $tmpFilePath = $_FILES['image']['tmp_name'][$i];    
            if ($tmpFilePath != "")
            {    
           $path = "upload/"; // create folder 
           $imagename = $_FILES['image']['name'][$i];
           $size = $_FILES['image']['size'][$i];

           list($txt, $ext) = explode(".", $imagename);
           $file= time().substr(str_replace(" ", "_", $txt), 0);
           $info = pathinfo($file);
           $filename = $file.".".$ext;
           if(move_uploaded_file($_FILES['image']['tmp_name'][$i], $path.$filename)) 
           { 
              $file_name_all.=$filename."*";
          }
          $file="upload/" . $filename ;
      }
  }



  $stmt = $this->conn->prepare('INSERT INTO help(name, email, phone, category, region, image, question, title, date)VALUES(:uname, :uemail, :uphone, :ucategory, :uregion, :uimage, :uquestion, :utitle, :udate)');
  $stmt->bindParam(':uname', $name);
  $stmt->bindParam(':utitle', $title);
  $stmt->bindParam(':uemail', $email);
  $stmt->bindParam(':uphone', $phone);
  $stmt->bindParam(':ucategory', $category);
  $stmt->bindParam(':uregion', $region);
  $stmt->bindParam(':uimage', $file);
    selection code.
    public function needhelp(){
        try{
            $stmt = "SELECT help_id, name, image, question, date FROM help ORDER BY help_id DESC";
            $result = $this->conn->query($stmt);    
            $result->execute();
            return $row = $result->fetchAll();
        }
        catch(PDOException $e){
            echo "query error" . $e->getMessage();
        }




    }
