Eliminare utenti dal database con Php.
Salve ragazzi!
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
[PHP]<?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';
$C->DB_NAME = 'nome db';e altro... [/PHP]
Come è facile intuire, il database del mio sito contiene una tabella chiamata users in cui ci sono tutti i dati degli utenti (username, email, password, tel., link facebook etc.)
Mi sapete dire come fare per creare un link - nella pagina impostazioni - tramite cui l'utente possa eliminare il proprio account? Cerco in rete da giorni ma non ho trovato nulla di buono, non mi funzionano i codici che ho provato.
Chi sa aiutarmi?
-
scusa la domanda...quindi vuoi semplicemente cancellare un utente dalla tabella users?
-
si e sto impazzendo...
-
Una prima idea(alquanto brutale ) potrebbe essere modificare il Template impostazioni_profilo.php aggiungendo al fianco del bottone per il submit un link del tipo
[HTML]<a href="cancella.php?id=<id_utente>">Cancella Account</a>[/HTML]
inserendo al posto di <id_utente> il relativo valore, dopo di che nella pagina cancella.php ricavi l'id dell'utente da cancellare con
[PHP]$id = $_REQUEST['id'];[/PHP]
e crei la query per la cancellazione..Spero di essere stato chiaro
