Description
There are a couple of tickets that would seem to benefit from storing revisions of post meta (#11049, #20299). We had a need for this feature in our Carrington Build and RAMP products and built it a few years back.
It handles the storing of post meta along with revisions, as well as restoring those revisions when someone restores an older version of a post(/page/etc.). There is an API for registering the post meta keys you want to track revisions of, it does not track all post meta keys by default.
There are two versions of the code. The bare-bones revisions framework code is here:
https://github.com/crowdfavorite/wp-revision-manager
https://github.com/crowdfavorite/wp-revision-manager/blob/master/cf-revision-manager.php
while I started adding features to a version that would be more user-friendly plugin, allowing the users to select which post meta keys they want to track revisions for:
http://plugins.svn.wordpress.org/revision-manager/
http://plugins.svn.wordpress.org/revision-manager/trunk/cf-revision-manager.php
If this would be a valuable addition to core, I'd be happy to help polish this up in whatever manner is most helpful. I'd recommend breaking out the code I started on for the admin form and having that be the extent of the "revision manager" plugin - basically it becomes a nicer UI for selecting additional post meta keys to track revisions for.

It's still outside the scope that the revisions team will primarily focus on.

- adds new wp_save_post_revision_meta() - called in _wp_put_post_revision
- adds wp_restore_post_revision_meta() - added in restore action
- also stores post format as revision meta (and restores on revision restore), seemed to be best way to store post_format
- requires http://core.trac.wordpress.org/attachment/ticket/16215/16215.9.diff to work correctly (stores meta on copy of current revision, only present after patch)
- wp_revisions_keep_meta filter to override storing of meta
- initial testing verified post format and related meta stored and restored correctly
20564+16215.diff combined patch for testing

We need the exact opposite approach of this patch. :-)
We should have a list of meta keys that we WILL revision, not a list of ones we WON'T. There should be no filter to opt out of revisioning of post format postmeta.

ok, this was the method suggested in #20299 so i went with it. a possible advantage of this method is it will catch new meta options as they are added or used, but i could also see how it could catch fields you didn't need.
i can change the method and include all current used metas, maybe add a filter for plugin authors to register new metas for revisioning?

I think we just need a few new wrapper functions (like add_versioned_meta()
, update_versioned_meta()
, and delete_versioned_meta()
) that don't check against wp_is_post_revision()
. Using these would "opt in" to metadata on revisions. (of course you could currently just use *_metadata('post'...)
functions, no?)
then on 'wp_restore_post_revision' (with 2 args)
$meta = get_post_meta( $revision_id, $key ); if ( empty( $meta ) ) delete_post_meta( $post_id, $key ); else update_post_meta( $post_id, $key, $meta ); // or whatnot.
which is pretty straight forward (and also "opt in").
Optionally, core can hook onto 'wp_restore_post_revision' and loop thru a filterable array of "versioned" meta so that the following could work:
add_filter( 'versioned_meta', 'my_versioned_meta' ); function my_versioned_meta( $meta_keys ) { $meta_keys[] = 'my_key'; return $meta_keys; }
#33
@

patch introduces add_versioned_meta()
, update_versioned_meta()
, and delete_versioned_meta()
adds the filter 'versioned_meta' and handles restoring versioned meta data in wp_restore_post_revision()
Lightly tested.

I don't think we're ready to bless this for plugin use. As you noted, they can just use the lower-level functions if they know what they're doing. So for this go-around, I'd skip wrapping it up all pretty. Taking a look at your patch now.

Yeah, that's cool. I was just working on this because it blocks #20299 which in turn blocks a couple other interesting tickets like #23314 and #23539
Figured if I got a couple working patches up it might move those next round.

Been seeing this lately in the postmeta table, post IDs 9212, 9213 and 9214 are revisions and all meta is empty (no values):
4040 9214 _wp_format_video 4039 9214 _wp_format_audio 4038 9214 _wp_format_image 4037 9214 _wp_format_quote_source 4036 9214 _wp_format_quote 4035 9214 _wp_format_url 4032 9213 _wp_format_video 4031 9213 _wp_format_audio 4030 9213 _wp_format_image 4029 9213 _wp_format_quote_source 4028 9213 _wp_format_quote 4027 9213 _wp_format_url 4022 9212 _wp_format_video 4021 9212 _wp_format_audio 4020 9212 _wp_format_image 4019 9212 _wp_format_quote_source 4018 9212 _wp_format_quote 4017 9212 _wp_format_url

In 20564-6.patch:

- When restoring from a revision, restore the format too.
- When saving revisions: add post format meta to the revision post only for the current post format, skip when empty.

Replying to azaozz: The original post contains all those meta keys with empty values as well, and the revision post is a complete copy, so I think that's the expected behavior. I also think that there should be a more general approach for all possible meta, rather than post formats only. Thoughts?
#46

Not sure that's needed either.
...the revision post is a complete copy, so I think that's the expected behavior.
No, not a complete copy. It's a copy of the post data, most fields are not revisioned. By default only title, content and excerpt are. That's why we have _wp_post_revision_fields()
.
Imagine a small site with 100 posts, each having 10 revisions. That's (1,100 * 7) nearly 8,000 rows in the post meta table just for post formats. And most will be empty. Now imagine a bigger site with 20,000 posts and 50 revisions each (that's not uncommon). Nearly 8,000,000 rows. And now imagine a really big site... :)
I also think that there should be a more general approach for all possible meta, rather than post formats only.
Yeah, when we open the API to revision post meta (agree with @markjaquith it's out of scope at the moment), thinking it should be opt-in. A lot of the post meta doesn't need to be saved in revisions.
#47
@
10 years ago
I'm pretty sure it's been mentioned somewhere before, but we can probably store all the revision meta in a single serialized _revision_meta key. I agree that adding keys to revisioned meta should be opt-in and that it's out of scope for 3.6, I just dislike the post-format-ish approach at _wp_post_revision_meta_keys()
, and the $single
assumption in get_post_meta
:)

We could, but having separate meta has some advantages. We could do a query to select posts by these meta fields which might be useful in some cases. Also that makes post formats more "futureproof".
Yes, currently the revisions meta is only for post formats, and the fields can only be "single" there. It's not very hard to turn parts of it into an API, perhaps 3.7?

Replying to azaozz: I think what Aaron meant in his comment is useful for posts only, but not really useful for revisions. I took a stab at the _revision_meta
approach in 20564.6.diff which should keep the meta table clean and small for revisions. If this works out we can do the same for revisioned terms (#23893). Not really looking to fix this ticket, but rather lay a good foundation for whatever is next in 3.7 and 3.8.
P.S. Sorry for the .6 vs -6 naming conflict, that's trac's auto-naming kicking in :)
#50
@
10 years ago
The only drawback I can think of for serializing all the meta into one field is size concerns. For formats, it shouldn't be a problem, but if it's opened up later as an API, what if some meta are very large? Potentially, the values would be saved into individual keys, but when combined they maybe too big to store... no? It's an edge case, but who knows.

For the unique key issue, if the key is actually unique, then get_post_meta( $revision['ID'], $meta_key )
should only have one value in the array making it unneeded to pass a unique flag to add_post_meta (since the loop only goes once). I had a unique param in my patch originally, but after I saw the commit I thought it unnecessary. Is there a different unique assumption that I'm missing?

Yeah, this works for post formats, not so sure for all meta (only need to add restoring of the post format from 20564-6.patch, perhaps to the same array). Still, having empty keys in the serialized array seems wasteful :)
As long as we know the post supports formats, we can recreate the empty keys programmatically, no need to store them in the DB. Example:
$all_meta = array_merge( array( '_wp_format_url' => '', '_wp_format_quote' => '', '_wp_format_quote_source' => '', ... ), get_post_meta( $revision->ID, '_revision_meta', true ) );
This brings another interesting question: when restoring from a revision, do we overwrite all data stored in the main post's formats meta? If yes, do empty meta keys from the revision overwrite (i.e. remove) the corresponding values on the main post?
User case:
- User creates a post, no format set.
- User saves a draft creating a revision.
- User edits the post, sets format to quote, enters data in 'url' and 'quote' meta fields.
- User restores to the first revision. At this point do we delete the data entered in 'url' and 'quote' on the main post or do we keep it? Logically we should delete it, but if we are keeping all post formats data ever entered on the main post, the user may expect to find it if he sets the format to quote again.

True, but we will need to do $meta[0]
everywhere. In the current code post formats meta doesn't support multiple keys, better to use the meta API properly and get/set a single key.

Replying to azaozz:
Only need to add restoring of the post format from 20564-6.patch, perhaps to the same array.
That's taxonomy and terms, not post meta, hence the similar patch in #23893 for taxonomy. If the the serialized _revision_meta approach works well for meta, we can take a similar approach with terms and not "pollute" the term_relationships table with relations to revisions :)
Still, having empty keys in the serialized array seems wasteful :)
Maybe. We can indeed check the emptiness of meta before storing their revisions to save some space, but I have mixed feelings about it. I don't think it will affect post formats all that much, but I keep thinking that a non-existent meta value is not the same as a stored empty string, especially for multiple values under one key. If there was a $default
argument to get_post_meta
like there is for get_option
, not storing the empty values would be a deal-breaker. So I lean towards doing delete_post_meta
for empty strings when saving post format metadata. Just thinking out loud here.
This brings another interesting question: when restoring from a revision, do we overwrite all data stored in the main post's formats meta? If yes, do empty meta keys from the revision overwrite (i.e. remove) the corresponding values on the main post?
I can try and answer this with a similar question :) When restoring from a revision, do empty fields (title or content) overwrite the corresponding values in the main post? Create a post with no title, save a few revisions, give it a title, save and restore a previous revision: do we set the title back to an empty string? The answer is yes, and I think post formats (and revisioned post meta in general) should not be any different.

What I mean is at the lowest level: we know the expected keys, so array( 'a' => '', 'b' => '', 'c' => 'something' );
doesn't have to be serialized, saved to the db and unserialized again when getting the data. We can remove the empty keys, save array( 'c' => 'something' );
and then add the empty keys on getting the data. This will work in exactly the same way as saving the original array.
The same is true when getting/setting the post format meta on revision posts. We know there are 7 meta keys, no need to add the empty.
I can try and answer this with a similar question :) When restoring from a revision, do empty fields (title or content) overwrite the corresponding values in the main post?
That's not exactly the same. From the discussion on #19570, we are keeping the unused data for post formats. Basically this is irrelevant post meta unless the user decides to switch back to a previously used post format. The question here is: do we "roll back" that irrelevant data when restoring a revision, and yes, logically we should.

- includes fix from #24477 (from itthinx)

For the ability for plugin devs to add custom meta to custom post type revisions (#13382), you do also need a kind of javascript "filter" for the data that is send with the autosave. Something like this http://jsfiddle.net/jTjzK/3/ (just a concept to extend the data var).

As you can see in the attached image the default meta fields are saved.
But what I would like to see is a way to "prepaire" the data that will be saved into the meta field. The post type in the image is a photo album, and instead of "normal" content it saves some image data and the server generates the post_content
from this meta field. So I don't have one html input field that matches an meta field, but a lot. There are different solutions to this: (1) create a field that does matches the meta field and that is updated by javascript on autosave (so you need a hook for that) or (2) a "jsfilter" to generate the data and pass it trough.
As I write this, I note that it is kinda focussed to my example, but what I actually would say is: could we make an autosave API where you can add data on client side and extract (and save) it on the server side?

Thank you for the more detailed description and the screenshot.
I think what you are looking for is a way to hook in right before the autosave, or a filter applied to the transmitted autosave data. This type of JavaScript hook or action is currently not standardized in WordPress - see ticket #21170 for more details and a proposed solution.
In the mean time you may be able to hook in using this:
$( document ).on( 'before-autosave', function() { /* Your Function */ } );
(based on this code)

- Only save metas that have changed
- Keep a serialized array of the 'whitelisted' (revisioned) meta keys
- When restoring a revision, traverse back thru past revisions to find the last time the meta was revisioned
While this patch works and the unit tests pass, it seems a little too complicated. I'm going to work on this a bit more - keeping the serialized array of the 'whitelisted' (revisioned) meta keys, but switching to only saving non-blank meta values. This will eliminate the complicated traversal back to find the previously stored meta. We will still be creating rows for each (non-blank) meta which I think is ok as long as we make that fact clear to developers.

I think that blank meta should be stored if exists on the current post. Sometimes a blank value is the intended value. A case an point would be a field with checkboxes, by setting a blank value I know they purposely didn't select anything from the list.
Thoughts?

The issue is that when retrieving meta, WordPress returns blank if the meta is not set, OR if the meta is blank - so not storing the meta is the same as storing blank meta :) (unless I'm missing something)
the trick here is that because I am tracking which metas are 'revisioned' for each stored revision, i know that a meta that is revisioned and for which no value was stored is in fact blank; therefore, when restoring a revision with a meta that is missing (but which was tracked), that meta is considered blank, and the restored value is set as blank (guess I could just delete it).
Does that make sense? in short, I am tracking blank metas, just not bothering to store them.

Replying to adamsilverstein:
In 20564.15.diff:
- Don't store blank meta values
- Track meta keys stored for each revision
- Updated unit test to test restoring blank meta
I think that blank meta should be stored if exists on the current post. Sometimes a blank value is the intended value. A case an point would be a field with checkboxes, by setting a blank value I know they purposely didn't select anything from the list.
Thoughts?

Let me expand a little on my previous example. Let's say I have 3 checkboxes, all for one meta_key and the values are 1,2,3. Now by default in my meta box I set 1,3 as checked. Now a user comes in and creates a post and decides none of them should be checked. Now not storing the data is accurate however it doesn't tell me that the user unchecked anything so when I render the field again do I assume I need to load the default values or now leave them all unchecked? I suppose a I could check whether or not the post is new or being edited but is that the best approach?
This solution requires checking for the meta and if the meta key exists.
Just throwing in some thoughts, thanks for taking the time to consider them.

I think you can solve your problem using metadata_exists to check to the presence of the meta data. I don't think this issue affects the revisioning of post meta, deserves some testing!

I have refactored the latest code on this ticket as a plugin - https://github.com/adamsilverstein/wp-20564
Only one additional hook is required to complete functionality (and only for the or the autosaving of post meta), I added that in 20564-new-action.diff
I haven't tested the plugin carefully yet, my next step is getting the existing unit tests to pass.

One more filter was required: on my list to document these new hooks/filters, the check for change wasn't quite right.
With 20564.20.diff and the plugin ( https://github.com/adamsilverstein/wp-20564 ) metas are revisioned.
I wasn't certain how to run the unit tests when a plugin is required, I found that dropping a copy of wp-20564.php in trunk/tests/phpunit/tests/post/ did the trick for me, with that in place and the patch, all tests pass.

I have tested this plugin & related patch and its working well.
I think it is highly desirable for the revisioned meta fields to be included in the revision diff UI.
On this related ticket: #29920 I added a filter that allows revisioned meta fields to be added here. I am updating the patch on this ticket to include this.
I have also made a new version of the plugin to handle this. I will open a PR on github with these changes.
UPDATE - here is the pull request on github: https://github.com/adamsilverstein/wp-20564/pull/2

Added the correct patch!
Also thought about the idea of using the current register_meta
function - which supports an $args
param to register meta keys for revisions.

- Milestone changed from Future Release to 4.1
After some discussion at WCSF, moving to 4.1 for the temporary hooks suggested by adamsilverstein and matt_eu above.

johnbillion asked me (https://wordpress.slack.com/archives/core/p1414551155002002) to split up the unit tests - however these tests are actually related to the plugin that uses the new hooks and should probably not belong in core. I've updated the patch to remove them.
I will open a PR on github to add the tests to the plugin.
Also added some more documentation.

@adamsilverstein, there are a lot of bug fixes available on the plugin on github as PRs, but none of them are getting resolved and merged into master. I had to create my own fork of the repo and merge in a lot of PRs, fix bugs, etc, in order to get the plugin to work. This isn't something the community can do, the maintainer (you?) needs to review, or set reviewers, and approve the PRs I guess? Is the github repo at parity with the plugin download on the wordpress site?

@chrissiq
Apologies for my lack of activity on maintaining the plugin, I hope to loop back to it soon to review and merge any PRs that are good. I welcome any help in form of reviewing PRs, writing tests, etc.
The github repo is at parity with the plugin in .org, when I get to merging the outstanding PRs I will update it as well.
