PHP: Maximum number of form (FILE) fields

I want to upload 50 files at the same time (well, a clients wants this 'amazing feature'). However, PHP only processes the first 20 form fields; after that, they just do not exist for PHP.

I've had this problem before but did not document proper开发者_如何学Cly how to solve it. I believe it's a PHP setting, but I can not find it.

In php.ini, change max_file_uploads = 20 to whatever value you need.

You need max_file_uploads setting in your php.ini file. Also do check the upload_max_filesize and pos_max_size settings, to be safe :)
