Tengo esta tabla para guardar los datos de sesión y pretendo hacerlo con esta clase php que tengo.
El problema es que no escribe nada en la Tabla de la BD. Lamentablemente el tutorial de la clase ya no está más en esa dirección y no hay forma de encontrarlo.
No veo donde está la falla. Los datos de conexión son correctos y no da errores!
Por favor, si alguien me puede dar una mano o tal vez alguien que usa ésta misma clase me puede orientar!!!
Tabla "sessions"
Código PHP:
CREATE TABLE sessions (
ses_id varchar(32) NOT NULL default '',
ses_time int(11) NOT NULL default '0',
ses_start int(11) NOT NULL default '0',
ses_value text NOT NULL,
PRIMARY KEY (ses_id)
