Question

这些文件是相对较小的XML，远远低于最大上传限制，我已将php.ini中的max_file_upload值调整为30.所有文件都可以以任意组合上传，最多16个。更重要的是，表单实际上不会发布。＆＃34; POST。＆＃34;它将动作到下一页，但是如果表单已经提交，我会输入一些代码来显示文本，如果选择了超过16个文件，它将赢得它。我对这一点感到茫然，对网络也没什么帮助。

Answer 1

除了max_file_upload之外，还有另外两个涉及可能相关的文件上传的ini设置。

upload_max_filesize（默认为2 MB）限制每个文件的上传大小，post_max_size（默认为8 MB）限制POST内容的总大小，包括文件上传。

如果您遇到任何限制，可能会导致您看到的行为。

由于这两者在执行php代码之前都是相关的，因此您需要查看php.ini（和/或.htaccess设置（视情况而定）并确保它们被设置为允许接受所有POST内容的级别。

PHP上传表格不会上传超过16个文件
