Hola,
No quiero parecer pesado pero no he conseguido llegar a solucionar el problema de las sesiones. Mi problema se puede resumir de la siguiente forma:
Tengo una pagina1 donde inicio la sesión y asigno valor a dos variables por distintos métodos:
Código PHP:
<?
// Inicializo la sesión
session_start();
// Registro por un método
session_register($variable1);
$variable1="funciono";
// Registro por otro método
$_SESSION["variable2"]= "SI";
// Voy a la página2 donde controlo el valor de las variables de sesión.
header ("Location: pagina2.php");
exit();
?>
Una vez que llego a la pagina2, muestro mediante echos los parametros de la sesion, ya que necesito saber el contenido de una variable
Código PHP:
<?
// Inicializo la sesión
session_start();
echo 'La sesión actual es: '.session_id().'<br>'; // Me devuelve el id de la sesion - CORRECTO
echo 'Path: '.session_save_path().'<br>'; // Me devuelve el path que he incluido en php.ini y es el CORRECTO
echo 'Nombre de sesión: '.session_name().'<br>'; // Me devuelve el nombre especificado en php.ini
echo 'Variable1: '.session_is_registered(variable2).'<br>'; // No me devuelve nada - CURIOSO
echo 'Variable2: '.$_SESSION["autentificado"].'<br>'; // No me devuelve nada - CURIOSO
?>
La verdad es que almacena algunos valores y otros no, y admite los parametros del php.ini, que a continuación os muestro por si os da alguna pista.
Código PHP:
[Session]
; Handler used to store/retrieve data.
session.save_handler = files
; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
session.save_path = C:\temp_sesion
;session.save_path =
; Whether to use cookies.
session.use_cookies = 1
; This option enables administrators to make their users invulnerable to
; attacks which involve passing session ids in URLs; defaults to 0.
; session.use_only_cookies = 1
; Name of the session (used as cookie name).
session.name = PHPSESSID
; Initialize session on request startup.
session.auto_start = 1
; Lifetime in seconds of cookie or, if 0, until browser is restarted.
session.cookie_lifetime = 0
; The path for which the cookie is valid.
;session.cookie_path = /
session.cookie_path = C:\temp_sesion
; The domain for which the cookie is valid.
;session.cookie_domain =
session.cookie_domain = http:\localhost
; Handler used to serialize data. php is the standard serializer of PHP.
session.serialize_handler = php
; Define the probability that the 'garbage collection' process is started
; on every session initialization.
; The probability is calculated by using gc_probability/gc_dividend,
; e.g. 1/100 means 1%.
session.gc_probability = 1
session.gc_dividend = 1000
; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
session.gc_maxlifetime = 1440
; PHP 4.2 and less have an undocumented feature/bug that allows you to
; to initialize a session variable in the global scope, albeit register_globals
; is disabled. PHP 4.3 and later will warn you, if this feature is used.
; You can disable the feature and the warning seperately. At this time,
; the warning is only displayed, if bug_compat_42 is enabled.
session.bug_compat_42 = 0
session.bug_compat_warn = 1
; Check HTTP Referer to invalidate externally stored URLs containing ids.
; HTTP_REFERER has to contain this substring for the session to be
; considered as valid.
session.referer_check =
; How many bytes to read from the file.
session.entropy_length = 0
; Specified here to create the session id.
session.entropy_file = C:\temp_sesion
;session.entropy_length = 16
;session.entropy_file = /dev/urandom
; Set to {nocache,private,public,} to determine HTTP caching aspects.
; or leave this empty to avoid sending anti-caching headers.
session.cache_limiter = nocache
; Document expires after n minutes.
session.cache_expire = 180
; trans sid support is disabled by default.
; Use of trans sid may risk your users security.
; Use this option with caution.
; - User may send URL contains active session ID
; to other person via. email/irc/etc.
; - URL that contains active session ID may be stored
; in publically accessible computer.
; - User may access your site with the same session ID
; always using URL stored in browser's history or bookmarks.
session.use_trans_sid = 0
; The URL rewriter will look for URLs in a defined set of HTML tags.
; form/fieldset are special; if you include them here, the rewriter will
; add a hidden <input> field with the info which is otherwise appended
; to URLs. If you want XHTML conformity, remove the form entry.
; Note that all valid entries require a "=", even if no value follows.
url_rewriter.tags = " a=href,area=href,frame=src,input=src,form=fakeentry"
Utilice para la instalación de php el appserver 1.9 y funciono en local con Windows XP. No parece ser problema de permisos ya que almacena los id's de las sesiones sin problemas, os lo prometo.
Os pido vuestra ayuda, por favor, no tengo por donde seguir y esto es crucial.
Muchas gracias y perdonad
