I'm googeling for hours now but can't find anything to my problem:
I'm building a plugin and want to embed a file input in its admin page. For this reason I'm giving the form-element the attribute enctype="multipart/form-data"
and I'm trying to access the file via $_FILES
, but it is empty!
Same with $_POST
.
Without enctype="multipart/form-data"
at least the filename and the other form fields appear in $_POST
.
I'm wondering if WordPress is removing direct access to these superglobals or somehow else preventing this regular way of uploading files.
I've read a lot about hooks and posting all forms to admin_post.php or admin_ajax.php but since my upload functionality is located in a class that's part of a big library with autoloading etc. it's not an option for me. My form is sending it's data to the current admin page (I tried it without the action
-Attribute but also specifying it action="admin.php?page=XYZ"
but nothing worked).
I would be thankful for every hint!
