PHP如何在不同的列中保存多个上传图像名称和路径？

Question

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

首先，它必须验证图像计数最小02和最大05，然后文件大小最大8MB，之后图像类型“JPEG”和“PNG”仅允许，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，它在会话中可以请求）。 在该文件夹中，应该创建另一个文件夹，如userName_ID_220（220为此必须从Database SQL max函数中选择最后插入的id）。 在此文件夹中，图像应该像userName_id_220_0.jpg一样移动和重命名，下一个图像应该像userName_id_220_1.jpg。

我必须保存数据库内的所有图像路径，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，如userName / userName_ID_001 / userName_id_220_1.jpg，如下图所示。

DB示例图像

我试过foreach但是它为每个图像创建了每一行。 所以请建议我一个解决方案。

我面临一些问题，比如我上传了2个图片获取$ file_type2 =的错误未定义偏移量（$ _FILES ['inputfcount3'] ['type'] [2]）; 如何修复该错误并简化此代码？

Answer 1

当你上传两张图片时，它自然会出现这个错误 - $file_type2是第三张图片不存在的。 您必须将所有$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
            )

    )

)

在我看来，你不需要任何foreach - 只需将你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。

基本名

这样你就不会覆盖以jgp结尾的文件，即使它是一个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 （如果您还没有发送每个帖子的表单）。
