为$ _FILES选择值[ <filename> ] [“ tmp_name”]

[英]Choose value for $_FILES[<filename>][“tmp_name”]

原文 2012-08-26 09:21:18 6 1 php

Is there a way to client-side choose the value for $_FILES[<filename>]["tmp_name"] instead of having it be randomly generated? 有没有一种方法可以让客户端在$_FILES[<filename>]["tmp_name"]选择一个值，而不是随机生成它？ For example, is there some type of attribute I can somehow append to the file itself, called "tmp_name", so that when it's uploaded the receiving PHP script reads my tmp_name rather than generating a random one? 例如，是否可以通过某种方式将某种类型的属性附加到文件本身上，称为“ tmp_name”，以便在上载时，接收PHP脚本读取我的 tmp_name而不是生成随机的？

No. 没有。

The uploaded file data is stored in a temporary file which is randomly named . 上载的文件数据存储在一个临时文件中 ，该文件名为。 And it's good that the user has no influence on that, it could be a security issue if he did. 最好让用户对此没有影响，如果这样做的话，则可能是安全问题。 You can configure the directory in which this temporary file will be created in your php.ini , but that's all. 您可以在php.ini中配置在其中创建此临时文件的目录，仅此而已。
