Real cases when you use $page->meta

[Zeka 972]

Hi.

Could someone provide real cases when you use $page->meta to store data? 

Thanks.

My module TrelloWire module uses $page->meta as an easy, site-independent way to associate module data with a page. The module creates Trello cards for new pages, and can update them through Trello's API whenever the page is changed. To do this, the module needs to store the ID of the card associated with that page somewhere. Using $page->meta was the easiest option, much simpler than creating a custom database table or programmatically creating a field when the module is installed. The caveat is that the value can't be updated or deleted through the user interface. However, that could be achieved through hooks.

You can see how I store and use the page meta data in TrelloWire::createCardForPage and TrelloWire::buildCardData 🙂

RockMatrix --> thats a modules similar to RepeaterMatrix. When a matrix item is created, a meta entry stores the reference to the page, where the matrix item lives on. That's similar to the TrelloWire example 🙂 

RockMeta --> that are fields for the PW backend that do not store their value in their own DB table but in page meta-data. This is great, because I can add Inputfields to existing Inputfields to make them more flexible without having to create many fields in the system.

ElasticsearchFeeder saves the document-ID returned by ElasticSearch and the time of the last sync to the correspondending page.

@bernhard, are those two publicly available? Could not find them nowhere)

@MoritzLost, @markus_blue_tomato Thanks, will look through your examples.

@bernhard I have a request from a client to provide a batch of fields that in most cases will act as controls of hooks that should or should not be run on page save, but this fields should also save the state, so there should be some storage and I was thinking that using page meta is the good route for such task. (Though now we have Combo field that also perfectly fit).  I'm also as @Ivan Gretsky interesting to see your implementation, of course, if it is possible. 

Thanks, guys. Best community.

Nope. Both are quite experimental at the moment. Not in the sense that things don't work, but experimental so that things might change, there are no proper docs etc...

Just used $page->meta() for a simple maillog that shows when (date/time) a mail was sent for the currently edited page (invoice) and to whom (mail address) 🙂
