Improve the media-new.php screen

[ocean90]

With #21391 we have the new screen for attachment edits.

nacin:

media-new.php shows the old form. (Keep in mind it allows for multiple uploads at once.) What should this workflow be? I don't know yet.

So ideas are welcome. How can we improve it?

Tempted to say change the "show" link to "edit" and just link to the new edit screen, even though that removes the convenience of uploading and editing the details of a batch at once.

Let's do it.

The show/hide links only show if you upload multiple files. So is it possible to detect if you've only uploaded a single file, and if so, redirect to the edit UI for that item?

What I tried to say in comment:5 was, when you upload a single file, the show/hide box is already expanded, correct? And if you upload multiple files you get a list of collapsed items. If we change 'Show' to an edit link, we also need to account for what happens when single items are uploaded. Do we just leave it collapsed and replace 'Show' with 'Edit'? Or perhaps redirect them directly to the edit screen?

In 22751:

Split media-new.php and media-upload.php into distinct files.

• media-new.php will remain the entry point for uploading isolated files, and for using the browser-based uploader (versus Plupload).
• media-upload.php is the legacy (pre-3.5) media uploader.

see #22083.

In 22752:

Remove cruft from media-new.php. No need to keep extra parameters around (including post ID, which is always 0 here). see #22083.

In 22755:

Have media-new.php return simple rows of basic attachment data, with an 'Edit' link next to each taking them to post.php (in a new window). Not ideal, but this is largely a fallback screen at this point.

This is bolted on to existing code, the vast majority of which is destined to be ripped out in 3.6 once things settle.

see #22083.

In 22759:

Revert accidental changes to admin/includes/media.php in [22755]. see #22083.

In 22764:

media-new.php: Remove unused scripts, strings, error handling, save handling, and save button. fixes #22083.

In 22777:

Redirect post-new.php?post_type=attachment to media-new.php. see #22491, #22083, #21391.
