Php / phplib error
have a problem with php/phplib. Every now and again i get
Warning: $user is not an object in page.inc on line 68
Fatal error: Member function used on a non-object in page.inc on line 68
On my pages. I am NOT using a variable named $user. I am doing a page_open and page_close on all pages (the error occurs in the page_close). Sometimes you can loose the error by closing all browser windows and restarting. Sometimes it shows on all pages, sometimes just on a few, or one. And most of the time it works just dandy.
If you would like to see my exact server config etc (aswell as some code snippet) please refer to the link below.

since footer is always called after header, do i need global directive in footer?
AFAIK, 'global' definition is local to the function it is used in. So you have always use global in functions/object methods. Another way to access globals variables - use $GLOBALS array.
Hi j2,
If you only want use phplibs to manage sessions variables you don't need use
"user" => "CS_User" parameter.
My code looks like:
<?php
// $theVar is a session variable. It was registered with REGISTER function
// $theNewVar is a new session variable I'm going to register it
// mySessClass is my custom session class in local.inc file
php_open(array("session"=> "mySessCla ss"));
echo "TheVar= $theVar";
$theNewVar = $theVar + 10;
$mySessClass->register("th eNewVar");
php_close();
?>

I think i wrote in the link i provided that i only added that since it was suggested by someone else, it makes no difference to my problem.
maxkir i dont think the global is the answer, since the use of global is not suggested anywhere in the phplib docs :-/

Will try wednesday / thursday.
Out of curiosity, what is the _real_ difference between your code and mine?
I think i am out of my league here :=)

I put the php_open() and php_close() outside of your functions.

Well, 'global' is not mentioned, but it is supposed to be used when you put your page_open/close code in functions - so, as aikon mentioned, you've changed variables scope.
Try adding 'global' just to make sure that I'm wrong ;-))). If you remove
"user"=>CS_User, it could bi simple
global $sess; in your functions.
Good luck,

Ah, now i see, rewriting the common inc in that fashion would make sure that each file that includes that file will get a page open and close.. I see. Now, if i would like to use another session setting i would just have to moce it to another common inc (or whatever filename) right?
This might very well work, but as i said, i wont have time to experiment until thursday prolly.
But i think i have seen the light :)

Just including common.inc will not do the trick.
When you make page_open, you read values of stored variables from DB,
when you do page_close, you save this values back to the DB. So you vave to call page_close *after* changing of variables you want to store.
Code like this:
include("common.inc");
$var_to_store = "value";
will not work if you will not call page_close() at the end.
So, common.inc shouldn't contain page_close() call.
You can do two ways (using code above):
<?php
include("common.inc");
$sess->register("var_to_st ore");
$var_to_store = "value";
session_footer();
page_close();
?>
OR ( if you leave page_close() in session_footer() )
<?php
include("common.inc");
$sess->register("var_to_st ore");
$var_to_store = "value";
session_footer();
?>
I'd do it this way:
<?php
include("common.inc");
session_header();
$sess->register("var_to_st ore");
$var_to_store = "value";
session_footer();
?>

Gah, how shall i call this?
Aikon mentioned the scope of variables first (which was the problem).. but maxkir aswell gave valuable input.
But since i cant split the points, the winner must be aikon.
Hey maxkir, posting another question in a sec should be easy, but it got me scratching my head :=)

I suggest that 'global' statement resolves variable scope problem ;-)))
Anyway, most important thing that you've got a solution.

IE5.01sp1 which is probably the culprit, with the cache bug. After the redefinition of my functions the problem seems to have dissapeared for other browsers tho.
<?php
function session_header($title) {
global $sess, $user;
page_open(array("sess" => "CS_Session", "user" => "CS_User"));
echo "<html><head><title>\n";
echo "$title\n";
echo "</title>\n";
echo "</head>\n";
echo "<body bgcolor=\"#B07879\" background=\"http://localhost/images/cs-logo-fill2.jpg\" topmargin=\"0\" leftmargin=\"0\" style=\"font-family: Arial, sans-serif\" >\n";
}
function session_footer() {
global $sess, $user;
echo '</body></html>';
print $user;
page_close();
}
?>
