 Posted: Wed Jan 24, 2007 2:32 pm Post subject: PEAR Auth : Use form inside HTML and Keep authentification |
 |
|
Hi,
I'm trying to use PEAR::Auth in my e-commerce application, but there are several things I cannot make working and do not understand.
In my example, I've got 2 pages : identification.php & shipping.php.
On identification.php I use the start() method to display and use the default login form :
| Code: |
<?php
$auth = new Auth("DB", $options_auth, null, false);
$auth->start();
?>
<html>
<head>...</head>
<body>
...
<?php
if ($auth->getAuth()) {
echo "<p>You're already logged in.</p>";
}
else {
// Display the login form
$auth->setShowLogin(true);
$auth->start();
}
?>
...
</html>
|
Already here, I'm not sure to use Auth as I should. In effect, If I don't use the first start() after pear::Auth instanciation, the second $auth->start() used to display form causes 2 warning :
| Code: |
Warning: session_regenerate_id() [function.session-regenerate-id]: Cannot regenerate session id - headers already sent in D:\Ben\Dev\iscommerce\admin\conf\Auth\Auth.php on line 741
Warning: Cannot modify header information - headers already sent by (output started at D:\Ben\Dev\iscommerce\commande\identification.php:99) in D:\Ben\Dev\iscommerce\admin\conf\Auth\Auth.php on line 765 |
Event I can perfectly understand that in order to create a session, Auth needs no headers to be sent...I'm surprised to notice that no example in the documentation and on the web uses start() method inside an html file.
Well, as it is however working fine, let's tell you about my second problem : keep the login status on the second page (shipping.php).
In my example, if I replace the "logged in" status display by a redirection to shipping.php like this :
| Code: | <?php
$auth = new Auth("DB", $options_auth, null, false);
$auth->start();
?>
<html>
<head>...</head>
<body>
...
<?php
if ($auth->getAuth()) {
//echo "<p>You're already logged in.</p>";
// Redirect to the shipping page
header('location: shipping.php);
}
else {
// Display the login form
$auth->setShowLogin(true);
$auth->start();
}
?>
...
</html> |
My shipping page code is as follows :
| Code: |
$auth = new Auth("DB", $options_auth, null, false);
$auth->start();
if ($auth->getAuth()) {
echo "You are logged in";
}
else {
echo "You are not logged in";
}
|
The problem is : my shipping page always show me "You are not logged in", whereas the login form works on the previous page. The login status seems not to be saved in session and forgot from one page to another.
Did anyone managed to have the PEAR::Auth library working ? If so, could this person post her code on tis forum ? That would be very helpful I think because Except the few documentation examples, I cannot find anyhting else on the web about a working Auth script...
Thanx for all to let your ideas about my problem, even if you don't have the entire solution, this could be interesting !

Bonjour,
Je tente comme d'autres d'utiliser PEAR::Auth, mais je reste perplexe sur plusieurs points.
Dans mon exemple, j'ai 2 pages : indentification.php et livraison.php
Sur identification.php, j'utilise la méthode start() pour afficher et utiliser le formulaire de login par défaut :
| Code: |
<?php
$auth = new Auth("DB", $options_auth, null, false);
$auth->start();
?>
<html>
<head>...</head>
<body>
...
<?php
if ($auth->getAuth()) {
echo "<p>You're already logged in.</p>";
}
else {
// Display the login form
$auth->setShowLogin(true);
$auth->start();
}
?>
...
</html>
|
Mais déjà là, je ne suis pas sûr d'utiliser correctement la bibliothèque. En effet, si je n'utilise pas le premier start() après l'instanciation $auth= new Auth(...), celui qui se trouve au milieu de ma page provoque 2 warnings :
| Code: |
Warning: session_regenerate_id() [function.session-regenerate-id]: Cannot regenerate session id - headers already sent in D:\Ben\Dev\iscommerce\admin\conf\Auth\Auth.php on line 741
Warning: Cannot modify header information - headers already sent by (output started at D:\Ben\Dev\iscommerce\commande\identification.php:99) in D:\Ben\Dev\iscommerce\admin\conf\Auth\Auth.php on line 765
|
Même si je comprend parfaitement le "headers already sent" en raison du fait que j'ai déjà fait affiché des caractères sur ma page, je suis surpris de ne voir aucun exemple de code qui utilise le start de la même façon que moi, intégré dans du HTML...
Mais puisque ça fonctionne pour le moment comme ça, je vais plutôt passer au second problème : garder l'identification active sur d'autres pages, sur ma page livraison.php par exemple
Dans mon exemple, si je remplace l'affichage du message m'alertant que je suis logué par une redirection vers livraison.php comme ceci :
| Code: |
<?php
$auth = new Auth("DB", $options_auth, null, false);
$auth->start();
?>
<html>
<head>...</head>
<body>
...
<?php
if ($auth->getAuth()) {
//echo "<p>You're already logged in.</p>";
// Redirection vers la page de livraison
header('location: livraison.php');
}
else {
// Display the login form
$auth->setShowLogin(true);
$auth->start();
}
?>
...
</html>
|
Avec un code sur ma page de livraison comme suit :
| Code: |
$auth = new Auth("DB", $options_auth, null, false);
$auth->start();
if ($auth->getAuth()) {
echo "You are logged in";
}
else {
echo "You are not logged in";
}
|
Le problème est le suivant : La page de livraison m'affiche tout le temps "You are not logged in", alors que le login fonctionne correctement sur la première page. Le statut de la connexion ne semble pas être sauvegardé en session et donc oublié d'une page à l'autre.
J'ai bien vu sur ce forum que [URL="http://www.developpez.net/forums/showthread.php?s=4fac782f6ccd2f3298c8da241775febd&t=222333&highlight=pear+auth"]quelqu'un d'autre avait eu ce problème[/URL], mais je trouve la solution avancée assez curieuse pour une bibliothèque censée nous faciliter la tâche...
Svp, est-ce quelqu'un pourrait publier dans les tutoriaux, How-to, etc... un exemple de code concrêt qui fonctionne ? C'est malheureux, mais je ne trouve rien d'autre que les quelques exemples de la documentation qui ne nous aident pas trop dans le cadre d'un vrai projet...
Merci de venir poster vos remarques, même si vous n'avez pas la solution miracle, peut-être que ça m'avancera quand même ! |

Hi,
sorry, I think I cannot help... but I have the same problem. This problem exists since i have updated to apache2 and php5. I don't know why - it works for me fine the time before... very strange.
Regards, Holger |

Hah!
I just got it to work.
You need to enable
| Code: |
output_buffering = On
|
Perhaps you have to ebalbe cookies in the session management.
regards, Holger |
