                if($insert){

        $statusMsg = 'Please select a file to upload.';
    }

    // Display status message
    echo $statusMsg;
    ?>

您的代码没有将 description 保存到数据库中。这就是为什么你不能显示它。

首先您需要在 table images.

中添加一个新列 description

之后，您必须像 $fileName

一样获取请求中发送的描述

$description = $_POST['description'];

您现在可以插入 images:

$insert = $db->query("INSERT INTO images (file_name, description, uploaded_on) VALUES ('".$fileName."', '".$description."', NOW())");

使用 PHP 和 MySQL 上传图像文件并将其存储在数据库中
