[PHP] Sessions and Objects using PHP4
I have RTFM and TTFE and still am having a heck of a time getting my
objects to play well between pages
The only real examples are in the notes for classes objects
http://us2.php.net/manual/en/language.oop.php
Basic usage
?
include_once(config.inc);
include_once(class.php);
$songbook = new songbook(); // defined in the class.php
session_register('songbook');
$songbook-get_stats();
$songbook-populate_manu();
$songbook-populate_series();
if (!isset($songbook-userid) || $songbook-userid == ) {
header(Location: login.php);
}
Now the login.php is basically the same but if the login correctly it
should set $songbook-userid to the username
require('common.php');
session_start();
include_once(class.php);
$songbook = new songbook();
session_register('songbook');
include(newheader.php);
if ( isset($_POST['submitit'])) {
$link = dbconnector();
$sql = select * from userinfo where
lower(username)=lower('.$_POST['user'].') and
lower(password)=lower('.$_POST['pass'].');
$result = mysql_query($sql);
if( mysql_num_rows($result) 0 ) {
$songbook-userid = strtolower($_POST['user']);
header(Location: green.php);
} else {
$errormsg = font size=3Invalid Username or Password.br\nPlease Try
Again./font;
}
}
So I guess what I am asking is how DO you make objects work across pages?

(are you on php4 or php5 btw?)

indeed, you must include classes for objects stored in a session before
starting the session. :-)
$songbook = new songbook(); // defined in the class.php
if you are creating this object on every page/call and then assigning it
to the session it will always have a blank/null userid. because
each call overwrites the old object thats stores with a brand new
one. so you need to check the session to see if a songbook
object is already available. so you only ever see the login screen in
your example.
session_register('songbook');
alternative is using $_SESSION. but if you do you must call
session_start() first:
session_start();
if (!isset($_SESSION['songbook']) || !is_object($_SESSION['songbook'])
|| !(get_class($_SESSION['songbook']) == 'songbook'))
{
$_SESSION['songbook'] = new songbook;
}
$songbook-get_stats();
$songbook-populate_manu();
$songbook-populate_series();
if (!isset($songbook-userid) || $songbook-userid == ) {
header(Location: login.php);
}
Now the login.php is basically the same but if the login correctly it
should set $songbook-userid to the username
require('common.php');
session_start();
include_once(class.php);
$songbook = new songbook();
session_register('songbook');
include(newheader.php);
if ( isset($_POST['submitit'])) {
$link = dbconnector();
$sql = select * from userinfo where
lower(username)=lower('.$_POST['user'].') and
lower(password)=lower('.$_POST['pass'].');
$result = mysql_query($sql);
if( mysql_num_rows($result) 0 ) {
$songbook-userid = strtolower($_POST['user']);
header(Location: green.php);
} else {
$errormsg = font size=3Invalid Username or

[PHP] Sessions and objects
I create a new object and then assign it to a session var $customer = new Customer($_GET['facilityID'], $_GET['customerID']); $_SESSION['acceptPayment']['customer'] = $customer; but later when I access that session var [in the the same file but in a different function and different instance], php gives me an error saying: The script tried to execute a methode or access a property of an incomplete object. Pleas ensure that the class definition lt;bgt;customerlt;/bgt; of the object you are trying to operate on was loaded _before_ the session was started at filepath/acceptPayment.php line 103 I did a little reading (rtfm) on php.net and saw that if session.auto_start is turned on, you couldn't use Objects with sessions. Well I checked my ini and the session.auto_start was set to 0, so I am now scratching my head in confusion. I require_once the Customer class and start the session after the requires and includes, so then I thought ok require_once so I change it to require and then it doesn't load the class the for some reasone (sigh). Any Ideas? Thanks for your help in advance Matt -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] sessions and objects
Don't store your object in the session, that is just bad design. Store a lookup value, then grab your object from your DB only when you need it.

RE: [PHP] sessions and objects
Why is this good design? If I create a user object, populate it, kill the connection to the database (or return it to the pool) and cache the object then I can retrieve it any time I want without having to hit the database. Not arguing, just curious as to your perspective.

[PHP] Sessions and Objects
If I save an object as a session var. will I still have access to its methods. Ryan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
