I would like to know, if it's possible to filter a file upload by name.
In my case i want that the uploader let me upload the file only if the file name contains the string
"miimage-example.jpg". And deny if does not contains it Ex:"miimage.jpg".
Is there any way to do that? i don't know how Wordpress handless the functions so i'm completely lost.
I will appreciate any help you could provide me. Thanks in advance.
