<input id="input-fcount-3" name="inputfcount3[]" multiple type="file" class="file-loading" accept="image/*">

首先它必须验证最小 02 和最大 05 的图像计数，然后是最大 8MB 的文件大小，之后只允许图像类型“JPEG”和“PNG”，错误应为 0。

然后我必须创建一个文件夹作为 userName(登录用户的用户名，它在 session 中，可以请求)。在该文件夹内，应创建另一个文件夹，如 userName_ID_220(为此，它必须从数据库中选择最后插入的 ID，可以使用 SQL max 函数)。在此文件夹中，图像应移动并重命名为 userName_id_220_0.jpg，下一张图像应为 userName_id_220_1.jpg。

而且我必须将所有图像的路径保存在数据库中，例如 pic0 列中的 userName/userName_ID_001/userName_id_220_0.jpg，其他图像路径和名称应保存到 pic1 列中，例如 userName/userName_ID_001/userName_id_220_1.jpg，如下所示图片。

我试过 foreach 但它为每个图像创建了每一行。所以请给我一个解决方案。

我遇到了一些问题，比如如果我上传了 2 张图片，就会出现错误 undefined offset for $file_type2 = ($_FILES['inputfcount3']['type'][2]);如何修复该错误并简化此代码？

最佳答案

当您上传两张图片时，它自然会出现此错误 - $file_type2 用于第三张不存在的图片。您必须将所有 $file_type 更改为:

$file_type2 = (isset($_FILES['inputfcount3']['type'][2]) ? $_FILES['inputfcount3']['type'][2] : '') ;

您的 $_FILES 数组如下所示:

Array
(
[inputfcount3] => Array
    (
        [name] => Array
            (
                [0] => test1.jpg
                [1] => test2.png
            )

        [type] => Array
            (
                [0] => image/jpeg
                [1] => image/png
            )

        [tmp_name] => Array
            (
                [0] => /tmp/phpq62nsC
                [1] => /tmp/phpKTijeC
            )

        [error] => Array
            (
                [0] => 0
                [1] => 0
            )

        [size] => Array
            (
                [0] => 63722
                [1] => 3254
            )

    )

)

如我所见，您不需要任何 foreach - 只需将您的数据库文件名放在一起，如上所示。我有一个建议:使用 basename($_FILES['file_upload_int']['name']) 作为文件名。

basename

这样你就不会覆盖以 jgp 结尾的文件，即使它是 png。

出于安全原因，我还建议您使用 PDO 而不是 mysql 函数和 $_POST 而不是 $_REQUEST(如果您还没有按帖子发送表格)。
