November 2, 2020 — È molto facile salvare le informazioni nel database di WordPress, tanto che non ce ne accorgiamo nemmeno. Lo facciamo quasi inconsciamente quando ci muoviamo come un pesce nell’acqua attraverso il WordPress Manager premendo i pulsanti, configurando i plugin o aggiornando gli stati dell’ordine.

Ma, come possiamo fare per recuperare manualmente quei dati e modellarli per un successivo utilizzo nei nostri progetti?

WordPress ci offre diversi strumenti per accedere al database in modo sicuro, ma senza dubbio la classe WP_Query sarà il nostro miglior alleato per tuffarci nel mare dei dati.
