如果这是转贴，我很抱歉。但是我看到很多问题都没有找到正确的答案 我正在尝试上传多个文件 + 一些信息，但是如果我提交包含 2 张图片的表单，一切正常，当我上传超过 2 或 3 个文件时，脚本运行完美，我得到所有表单元素的未定义索引。

对不起，如果写得不好，我是初学者，在此先感谢您的帮助
最佳答案
问题是有一个大文件(4mb 图片)而 php 无法发布这个大小的图片所以你必须在上传之前调整你的图片大小.. 非常感谢 Felippe Duarte。
关于php - 无法在一个表单中上传多个文件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37056547/
