复制图像但只执行一个查询

Question

我在插入mysql时遇到问题。 此功能应将图像传输到图像文件夹，并为每个图像创建一个新查询，这样如果有3个图像，则执行3个查询，但只执行第一个

public function insertNews($author, $subject, $content)
{
    if($this->databaseConnection())
    {          

        // * So this is initalizing our database, now all we have to do is create a simple query.

        $unique_id = bin2hex(random_bytes(3));

        $insert_news = $this->db_connection->prepare("INSERT INTO news (author, subject, content, time, uniqueid) VALUES (:author, :subject, :content, NOW(), :id)");
        $insert_news->bindValue(':author', $author, PDO::PARAM_STR);
        $insert_news->bindValue(':subject', $subject, PDO::PARAM_STR);
        $insert_news->bindValue(':content', $content, PDO::PARAM_STR);
        $insert_news->bindValue(':id', $unique_id, PDO::PARAM_STR);
        $insert_news->execute();

        // * Checking if any images are waiting to be uploaded

        if(isset($_FILES['images']) && !empty($_FILES['images']['name']))
        {
            $extension = array("jpeg", "jpg", "png", "gif");

            $insert_images = $this->db_connection->prepare("INSERT INTO news_images (news_id, location) VALUES (:id, :location)");

            foreach($_FILES['images']['tmp_name'] as $key => $tmp_name)
            {
                $file_name = $_FILES["images"]["name"][$key];
                $file_tmp = $_FILES["images"]["tmp_name"][$key];
                $ext = pathinfo($file_name, PATHINFO_EXTENSION);

                $tname = bin2hex(random_bytes(10));
                $temp = explode(".", $_FILES['images']['name']);
                $newfilename = $tname . '_news.' . $ext;

                $location = "images/".$newfilename;

                if(in_array($ext, $extension))
                {

                    if(!file_exists($location))
                    {
                        // * Now we have to upload it to the database

                        $insert_images->bindValue(':id', $unique_id, PDO::PARAM_STR);
                        $insert_images->bindValue(':location', $location, PDO::PARAM_STR);
                        $insert_images->execute();

                        // * moving file
                        move_uploaded_file($file_tmp = $_FILES["images"]["tmp_name"][$key], $location);
                    }
                }
            }
        }      

        header('Location: news.php');
        exit();  
    }
}
