E' sabato e non c'è giorno migliore per aprire la seguente discussione

Parto postando i file interessati nel problema:

Preannuncio che parliamo di un sito in php con cui gestisco gli utenti.

nella cartella "/controlli" ho il file impostazioni_profilo.php

e nella root principale ho il file di configurazione config.php che contiene:

[PHP]// MySQL SETTINGS
//
$C->DB_HOST = 'host';
$C->DB_USER = 'sqluser';
$C->DB_PASS = 'pass';
$C->DB_NAME = 'nome db';

e altro... [/PHP]

Come è facile intuire, il database del mio sito contiene una tabella chiamata users in cui ci sono tutti i dati degli utenti (username, email, password, tel., link facebook etc.)

Mi sapete dire come fare per creare un link - nella pagina impostazioni - tramite cui l'utente possa eliminare il proprio account? Cerco in rete da giorni ma non ho trovato nulla di buono, non mi funzionano i codici che ho provato.

Chi sa aiutarmi?
