Overview
Triggering events when attachments are created, updated or removed.In the following examples we show how to trigger a state transition when users add, update or remove attachments to a page or blog post in a specific workflow state.
Attachment created
If the workflow is in the "Approved" state, adding an attachment will trigger transition to the "In Progress" state.
{workflow:name=Attachment added}
{state:In Progress}
{state}
{state:Approved}
{state}
{trigger:attachmentadded|state=Approved}
{set-state:In Progress}
{trigger}
{workflow}
Attachment updated
If the workflow is in the "Approved" state, updating an attachment (uploading a new version of existing attachment) will trigger transition to the "In Progress" state.
{workflow:name=Attachment added}
{state:In Progress}
{state}
{state:Approved}
{state}
{trigger:attachmentupdated|state=Approved}
{set-state:In Progress}
{trigger}
{workflow}
Attachment removed
If the workflow is in the "Approved" state, deleting an attachment will trigger transition to the "In Progress" state.
{workflow:name=Attachment added}
{state:In Progress}
{state}
{state:Approved}
{state}
{trigger:attachmentremoved|state=Approved}
{set-state:In Progress}
{trigger}
{workflow}
Attachment version removed
If the workflow is in the "Approved" state, deleting an attachment version will trigger transition to the "In Progress" state.
{workflow:name=Attachment added}
{state:In Progress}
{state}
{state:Approved}
{state}
{trigger:attachmentversionremoved|state=Approved}
{set-state:In Progress}
{trigger}
{workflow}
All of the above
If you want to transition on any of the events listed above, you can use the attachmentschanged (note the 's') event, like so:
{workflow:name=Any attachment event}
{state:In Progress}
{state}
{state:Approved}
{state}
{trigger:attachmentschanged|state=Approved} {set-message:duration=PT1M}
Attachment added, edited or deleted:
|| File | @filename@ |
|| Size | @size@ bytes |
|| Comment | @comment@ |
{set-message}
{set-state:In Progress}
{trigger}
{workflow}
We've included a message to provide some details about the attachment; the details are derived from Event references which are available in all attachment-related events. Here's example output:
