Triggering events when documents are created, edited ...

I have tried searching but can’t find anything remotely resembling this.

I would like to create thumbnails of images within a document when that document is created. Updating the thumbs when the doc is edited and deleting them when the doc is purged.

The application in my case is Ditto, if a story has an image then the summary listing shows a thumb. Is it possible to cause code to be executed before and/or after a doc is created, edited or deleted?

If so then a pointer to a TFM I could R would be appreciated, if not, what’s the best way to go about this?

All of the following events are available for documents. These can be accessed by creating a plugin.

OnBeforeDocFormDelete
OnBeforeDocFormSave
OnCreateDocGroup
OnDocFormDelete
OnDocFormPrerender
OnDocFormRender
OnDocFormSave

Sigh, just found events and plugins and was about to edit my post.

My processing only applies to documents created from a specific template. The documentation says that $modx->documentObject[’template’] contains the template ID, do I assume this is actually the template name?

I believe it’s the template ID, not its name. You’ll have to do a query of your own to get the correlation between ID and name.

OK, I create a doc from a template, when saving this doc I can use the OnDocFormSave event to create a thumbnail.

I then edit the document and edit the contents of the TV containing the image file, perhaps erasing it, perhaps changing the image filename.

When I save the document I can create a new thumbnail using the OnDocFormSave event. However the old thumbnail is now detached and represents unreclaimable resources.

Do I use the OnBeforeDocFormSave event to access the previous value?

Also the delete events, are they when items are marked for delete or when the item is actually removed?

Hi ed,

The FormDelete events occurs before and after a document is flagged as deleted and not when the document is actually delete. I think it would be a great idea to add an event when the document is being removed from the system.
