Add parameter $real_mime to wp_check_filetype_and_ext

[Tkama]

In some cases, I need the parameter $real_mime in hook ​wp_check_filetype_and_ext. I don't see any reasons to not pass it there.

<?php
return apply_filters( 'wp_check_filetype_and_ext', compact( 'ext', 'type', 'proper_filename' ), $file, $filename, $mimes, $real_mime );

Thanks @Tkama,

I think something like this could be really helpful for people trying to get around issues like #45615. I'm expecting to make some changes to the way this works in 5.1 so let's include this ticket in the process.

Cheers!

If #40175 doesn't land in 5.1 (and maybe even if it does) we should do this to help folks experiencing issues like #45615 more easily filter wp_check_filetype_and_ext(). Going to mark this as task/blessed and revisit depending on #40175.

Aye, this seems like a reasonable alternative to landing #40175 in 5.1.

[joemcgill]

Let's go ahead and do this for 5.1.

In 44677:

Media: Add a $real_mime parameter to the wp_check_filetype_and_ext filter.

This allows more accurate filtering of the filename and extension given to uploaded files.

Props desrosj, Tkama.
Fixes #45707.

@joemcgill, @desrosj: As this is the workaround for the #40175, it'd be good to have a dev note explaining how to use it.

[joemcgill]

@pento, @desrosj – I'll write a dev note.

[desrosj]

As far as I can tell, this never received a developer note. Removing the needs-dev-note keyword.
