用php中的一些上传文件清空请求

Question

I have a little problem about upload files in ajax. I sent a form-data to my backend server. The problem is that sometimes, depending on the files my backend doesn't receive anything. Nothing on $_REQUEST, nothing on $_POST, $_GET, $_FILES or even in file_get_contents(php://input).

I have already tried to put my memory_limit to -1 with post_max_size to 0 and my upload_max_filesize to 16M.

I tried with a small picture, an heavy one and one between the two. The small failed. The heavy and the other one are good.

Did any of you have a clue about this problem ?

Edit : I'm using angularJS (angular 1.x.x) on my front-end.

Answer 1

Did you set the form encoding type to multipart/form-data?

<form action="foo.php" enctype="multipart/form-data" method="post">...

You didn't say how you were sending the files to the server via AJAX, but this SO answer Angularjs $http post file and form data would probably be helpful to you.
