Revision history for pod fields

[bustapaladin]

Pretty much what these fine folk here are asking:
https://wordpress.org/support/topic/add-revision-history-to-custom-fields?replies=2

But then for the pods plugin and the fields it creates. So if someone edits a custom field on a custom post type it tracks the changes somewhere.

Also be able to clear the history and set the limit of how much is stored ,etc..

It could be packaged as a module you can enable or disable.

see https://de.wordpress.org/plugins/wp-post-meta-revisions/ maybe that's all you need ;)

Does it support custom post types?

From reading this I'm not sure: https://wordpress.org/support/topic/custom-post-types-235?replies=1

How would I now use it for pods plugin?
Like this?

function add_meta_keys_to_revision( $keys ) {
    $keys[] = 'uname', 'suspision', 'other_name';
    return $keys;
}
add_filter( 'wp_post_revision_meta_keys', 'add_meta_keys_to_revision' );

if anyone is looking for a way to achieve this, I've made a gist that might help someone. Good luck!

Hi @JimSRush and others on this thread.

I added the gist mentioned above to our functions.php and custom field changes are still not triggering revisions (although title, author, and excerpt do).

I have also tried these plugins, no luck:

https://wordpress.org/plugins/wp-post-meta-revisions/

@jaycollier I'd suggest you start by looking at what's happening in the $_REQUEST object - can you see your custom fields in there? They're prefixed by pods_meta.., so the gist may be failing at the isset step, where it checks to see if they're set.

Also, another thing you could try is double checking that this function is working properly, since this is the bit where it adds the list of fields to check changes against - if it's not working, it won't trigger a revision.

function my_revision_fields( $fields ) {
	// return the pod story type and extract the fields
	$story = pods('story');
	foreach ($story->fields as $key => $value) {
		$fields[$key] = $value['label'];
	}
	return $fields;
}
add_filter( '_wp_post_revision_fields', 'my_revision_fields' );

In this case, our pod name was 'story' so you'll need to change it to whatever the name of your pod is - apologies I didn't make this clear. I'll update the gist.

@jaycollier I've updated the gist with some more in depth comments - sorry about that - there's a couple of other things that you'll need to update. Please post your code here with your field names etc and I can take a closer look if you'd like?
