1. Create a workflow with trigger "file access"
2. Filter: "filename like /.*/"
3. Script: "echo '%e %i %a' >> /path/to/a/file"
4. Open a file in web or webdav or sync with desktop client
5. Run 'sudo -u www-data php -f /var/www/nextcloud/cron.php' on cli

Workflow Script app

Workflow Script app version: 1.5.1 & 1.6.0

Server configuration

Operating system:
Ubuntu 20.04.2

Web server:
Apache v2.4.41

Database:
MySQL8 v8.0.23-0ubuntu0.20.04.1

PHP version:

Inizia dal punto di ingresso cron indicato, /var/www/nextcloud/cron.php, e dalla gestione del trigger di accesso ai file dell’app Workflow Script. Riproduci il workflow con le versioni di Nextcloud indicate, quindi verifica che l’apertura di un file faccia sì che lo script aggiunga, come previsto, l’operazione sul file, l’ID del file e il nome utente.
