Salve a tutti,
ho seguito passo passo un tutorial online per la creazione di user e password con relativo accesso.
PHP Login script tutorial
Mi funziona quasi tutto. Infatti come risposta mi esce anche [ Login Successful ].
Nel data base ho creato il seguente username di prova:
username: fabio
password: 1234
Il problema e' che una volta inserito user e password nella pagina http://www.slmty.com/main_login.php mi esce il seguente errore di codice/database.
---------------------codice:// Check if session is not registered, redirect back to main page. // Put this code in first line of web page. Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/51/10874451/html/login_success.php:3) in /home/content/51/10874451/html/login_success.php on line 4 Deprecated: Function session_is_registered() is deprecated in /home/content/51/10874451/html/login_success.php on line 5 Login Successful
qui di seguito trovate tutte le pagina che ho creato. sapete come posso risolvere? grazie mille
