无法编辑数据库PDO PHP中的图像

I can succesfully save the image from my database using this code

if(isset($_POST['btn-update'])){


    $id = $_REQUEST['id'];

    $sql = "SELECT * FROM article WHERE id=:id";
    $query= $db_con->prepare($sql);
    $query->execute(array(':id' => $id));

    while($row=$query->fetch(PDO::FETCH_ASSOC)){
        $images_ = $row['image'];
        $files_ = $row['file'];
    }

$file_image = $_FILES['image-files'];
$file_image_Name = $_FILES['image-files']['name'];
$file_image_TmpName = $_FILES['image-files']['tmp_name'];
$file_image_Size = $_FILES['image-files']['size'];
$file_image_Error = $_FILES['image-files']['error'];
$file_image_Type = $_FILES['image-files']['type'];

if(!empty($_FILES['image-files']['tmp_name'])){
//handle first upload
    $file_image_Ext = explode('.', $file_image_Name);
    $file_image_ActualExt = strtolower(end($file_image_Ext));
    $file_image_allowed = array("jpg", "jpeg", "png");

    if(in_array($file_image_ActualExt, $file_image_allowed)){
        if($file_image_Error === 0){
            if($file_image_Size < 1000000){
                $file_image_NameNew = "image-".uniqid('',true).'.'.$file_image_ActualExt;
                $file_image_Destination = 'uploaded_files/uploaded_files_articles_images/' .$file_image_NameNew;
                move_uploaded_file($file_image_TmpName, $file_image_Destination);
            }else{
                echo "You file size is too big!";
            }
        }else{
            echo "There was an error uploading the file!";  
        }
    }else{
        echo "You cannot upload files of this type!";
    }

}else{
    $file_image_NameNew = '';
}

if($user->InsertArticle($articleTitle,$date_today,$bodyContent,$file_image_NameNew))
{
    header("Location:admin-index?UploadedSuccesfully!");
}
}

Now what I am trying to do is edit the image but it seems like my code is missing something and I couldn't figure out why is it not succesfully editing.

Here's my code for editing the image from database

$location = $_FILES['image']['name'];
$fileTmpNameLocation = $_FILES['image']['tmp_name'];

if(!empty($_FILES['image']['tmp_name'])){
        //allow file types
        $fileExtLocation = explode('.', $location);
        $fileActualExtLocation = strtolower(end($fileExtLocation));
        $allowedLocation = array("jpg", "jpeg", "png");

        if(in_array($fileActualExtLocation, $allowedLocation)){
            $fileNameNewLocation = $images_;
            $fileDestinationLocation = 'uploaded_files/uploaded_files_articles_images/' .$fileNameNewLocation;

            move_uploaded_file($fileTmpNameLocation, $fileDestinationLocation);
        }
    }else{
        $fileNameNewLocation = '';
    }

if($user->UpdateFile($id,$title,$content,$fileNameNewLocation)){

        $user->Redirect('edit-index.php?UpdatedSuccesfully');
    }else{
        echo "There's something wrong!";
    }

Here's my UpdateFile Method

public function UpdateFile($id,$title, $content, $image){
        try{
            $stmt = $this->db->prepare("UPDATE article SET title=:title, content=:content, image=:image WHERE id=:id");

            $stmt->bindParam(":title", $title);
            $stmt->bindParam(":content", $content);
            $stmt->bindParam(":image", $image);
            $stmt->bindParam(":id", $id);

            $stmt->execute();

            return $stmt;

        }catch(PDOException $ex){
            echo $ex->getMessage();
        }
    }

Could someone help me out please.
