Content Before Validate Data for Joomla

When it runs: During admin save, immediately before JForm validation runs on submitted data.

Last chance to adjust form data or add custom validation logic via the event.

Each run also includes who was logged in at the time and what kind of item was involved — see audit_user and audit_type in Payload Fields below.

This trigger is active when Platform Events are turned on in Joomla (System → JOrchestrator) and matching flows are set to Active.

When this trigger fires, JOrchestrator starts the flow and passes the incoming event or request data to the next connected step. Configure filtering, payload shape, and security on the Design tab.

Content Before Validate Data is a trigger in the Joomla Events › Content Events group. Triggers start a flow. They listen for an external signal — a CMS event, inbound HTTP call, payment notification, or schedule — and pass the incoming data to the first downstream step.

Typical reasons teams add Content Before Validate Data to a flow:

• Automate backend work when Joomla fires ContentBeforeValidateData
• Notify administrators or sync external systems on this CMS lifecycle event
• Enrich or validate CMS data before it is persisted
• Audit user, content, or extension activity without custom plugins

During admin save, immediately before JForm validation runs on submitted data.

Common patterns on the canvas:

1. Content Before Validate Data → Send Notification (admin alert)
2. Content Before Validate Data → Insert Row (audit log)
3. Content Before Validate Data → If → Send Email / Update Article

General → Joomla context filter — com_content.article before article form validation.

The designer shows these tabs for this node:

After this step runs, later nodes can reference these fields using placeholders such as {{content_before_validate_data.context}}.
