Caption editing in the media modal library view

[koopersmith]

When inserting an attachment into a post or creating a gallery, the user should be able to easily change the caption of any attachment via a text box immediately below the attachment's thumbnail. This caption will then be synced to the database as soon as the text field is deselected.

Currently, the attachment template in the media modal library view contains a div with the "describe" class, but nothing more. What we need now is…

• An option in the workflow controller to support inline caption editing.
• The caption rendered in the attachment template.
• The caption synced to the database on save.

Editing a caption would also need to sync/reload the gallery preview in MCE (if there is a gallery).

Replying to azaozz:

Editing a caption would also need to sync/reload the gallery preview in MCE (if there is a gallery).

For galleries, yes. This should happen automatically with #21815.

For attachments, I'm not so sure; it's actually one of the pieces that's up for debate. I think the most recent resolution was that once an attachment is inserted into a post, it is no longer synced with the database.

Right, image attachments that are inserted in a post stop being "attachments" and become part of the post. The size, alignment, caption can be edited as part of the post.

Caption editing in the media modal library.

• Adds a describe option to the workflow controller to support inline caption editing.
• For images, descriptions are mapped to the caption attribute.
• For other media items, descriptions are mapped to the title attribute.
• Descriptions are saved when the textarea's change event fires (i.e. when the textarea is blurred).

fixes #21807, see #21390.

Hi,
I see that description gets mapped to different fields depending on the type of attachment. Will we be adding the ability to specifically modify individual fields from here in the future (like the image title and alt tag fields) or will that be restricted to the main Media Library interface? If so, is there a better ticket to ask this question or track progress for that?

Thanks
