Limitare le revisioni degli articoli in WordPress
La versione 2.6 di WordPress introduce la possibilità di salvare una copia degli articoli ogni volta che vengono modificati. In questo modo, all’occorrenza, è possibile ripristinare per ciascun articolo una versione precedente.
E’ una funzionalità senza dubbio molto utile, che però va ad aumentare le dimensioni del database, dal momento che per ogni revisione viene inserita una nuova riga nella tabella wp_posts.
Per evitare che il database diventi troppo pesante, è possibile disabilitare questa funzionalità, oppure limitare il numero di revisioni per ogni articolo. E’ sufficiente aggiungere nel file wp-config.php queste righe:
[PHP]
// imposta massimo 3 revisioni per articolo
define (‘WP_POST_REVISIONS’, 3);
// imposta il salvataggio automatico ogni ora
define(‘AUTOSAVE_INTERVAL’, 600);
[/PHP]
