[PHP] $_SESSION only takes 1 character?
Hi there, I've got some strange behaviour here (at least, I can't explain it). I'm running PHP 4.2.3 on a Mandrake 9.0 machine. I'm using sessions in my little app and want to use the $_SESSION-variable to keep track of all my variabeles. Well, when I tell it $_SESSION[something-intelligent] = $myName; echo($_SESSION[something-intelligent]); I get Tim on my screen. But when I do: $nr = 12; $_SESSION[things][$nr][intelligent] = $myName; echo $_SESSION[things][$nr][intelligent]; I don't get any output at all! Can anyone shed any light on this? Thanks in advance!! -- Kind regards, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] [Session-objects] Call to a member function on a non-object
Hi people,
As I understand it, object are unserialized into their former Class, if
that Class is in memory. That's right, right?
Well, consider the following code:
include_once(../config.inc.php);
include_once($WORKDIR.obj/foto.obj.php);
if($type == 1)
{
$foto = new Foto();
}
if(isset($_SESSION['foto']))
{
$foto = unserialize($_SESSION['foto']);
}
$foto-makeInputFoto($type);
$_SESSION['foto']=serialize($foto);
It's for a page that can edit or add a foto in(to) the database. If I run
it like this, with ?type=1 in the URL, it works the first time, but after a
reload of the exact same page, I get a 'Call to a member function on a
non-object' in the line '$foto-makeInputFoto($type);'. Why is that? It's
already a Foto-object, because I unserialized it, isn't it?
I also tried:
if($type == 1 !isset($_SESSION['foto']))
{
$foto = new Foto();
}
elseif(isset($_SESSION['foto']))
{
$foto = unserialize($_SESSION['foto']);
}
With exactly the same effect. Any idea on how I can solve this? Tia!

[PHP] [Class] Behaviour global variables
Hi there,
I'm forgetting something, but I can't seem to get to it... Consider the
following Class.
class Test
{
var $a;
var $b;
function Test()
{
$this-a = 2;
$this-b = 5;
}
function Show()
{
global $a, $b;
echo(a: .$a);
echo(a: .$this-a);
echo(b: .$b);
echo(b: .$this-b);
}
}
After proper initialisation, calling the function Show() gives:
a:
a: 2
b:
b: 5
What am I forgetting here? Tia for answers!

[PHP] [Class] global again, not working?
Hi people,
Again, a problem with global. Maybe you can shed a light on this one...
Consider this part of a class (with [...] I marks things I left out, which
aren't important for the problem, FAFAIK):
class FotoView
{
[...]
var $fotos;
var $cats;
var $start;
var $limiet;
[...]
/**
* Constructor
*/
function FotoView($start,$cats=NULL,$admin=FALSE)
{
$this-limiet = $this-getLimit();
[...]
$this-start = $start;
[...]
echo(1:.$this-start. .$this-limiet);
$this-fotos = $this-findFotos();
}
function getLimit()
{
global $WORKDIR;
include_once($WORKDIR.obj/dbconnection.obj.php);
$db = new DBConnection();
$result = $db-query(SELECT lijst_x, lijst_y FROM config);
$data = mysql_fetch_row($result);
return ($data[0]*$data[1]);
}
[...]
function findFotos()
{
global $start, $cats, $limiet, $urlfotoview, $WORKDIR;
echo(2:.$this-start. .$this-limiet);
echo(3:.$start. .$limiet);
[...]
Okay, $WORKDIR is set in the page that calls this class, it works (checked
it). You can see three echo's in there. The result from those are:
1: 0 20
2: 0 20
3: 0
Can anyone explain to me why in findFotos() the defining of $limiet doesn't
work correctly? Why isn't a reference made to $this-limiet? I'm really at
a lost, here... Any help is appreciated!

[PHP] Maximum in SQL query?
Hi people, It seems that MySQL only accepts queries that are 470 characters or smaller when I use PHP. Is this a known thing? Can I change it somehow?

[PHP] Moving a file with 'rename'?
Hi people, I want to move a file from one location to another. I expect I can only do this with 'rename', because there's no 'move'-command (at least nog in the manual). Following situation: original file: /var/www/html/webfotos/tmp/thumb_phpibmGBF.jpg with /var/www/html/webfotos being a symlink to /home/cvd/sanbox/webfotos new location: /var/www/html/foto/0/0/0/0/.thumb.jpg syntax: rename($old_location, $new_location); Error: Warning: Rename failed (Invalid cross-device link) in /home/cvd/sandbox/webfotos/admin/save.php on line 95 When I 'su' to 'apache' (the user under which the httpd is running), I can do the following without any error: mv /var/www/html/webfotos/tmp/thumb_phpibmGBF.jpg /var/www/html/foto/0/0/0/0/.thumb.jpg Any ideas on why I get the error and how I can solve it?

[PHP] [Session] SID automatically add on all pages?
Hi people, Just a question, I'm building components for a customer who wants some interactivity within his site, but still wants to build the site himself. One thing that would be interesting would be Session management. Now, if I just tell him to make all his own pages with .php ext instead of .html, would did be enough if --enable-trans-sid is used (and php.ini is correctly configured)? It seems to work here, but I want to know if I forgot something important... -- Kind regards, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] [Session] SID automatically add on all pages?
Hi Justin, Thx for the reply Justin French wrote: using functions like session_start() and the registering of session variables ($_SESSION['something'] = foo;) will establish/maintain a session. Yes, I understand. Sessions need to be started. But once they have started, do I need to re-affirm the session on every page, or will it hold for a few pages, until the session-variables will be used again ... simply converting your files to .php and compiling with enable-trans-sid will not give you sessions. ... when I do this? -- Kind regards, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] [Session] SID automatically add on all pages?
Hi Justin, Thx again for the answer. Justin French wrote: Well, you really need to check out a decent article/tutorial on sessions, Nah, I think I explain my question a little wierd and that's why you don't understand me... I've worked with sessions lots of times (although mostly in Java Servlets). Or something must be really crooked with my knowledge of standard sessions... because it's a lot more in depth than can possible be explained here. But as a bare minimum, each page would need to call session_start() BEFORE the HTML tag or any other content is sent to the browser. Ah yes, I forgot about that... I need to resume the session, of course. Would session.auto_start set to 1 work without these session_start()'s? The thing is, I need as less as possible of a hassle to have the sessions work... Read on for an explanation. You'd also need to register variables to the session (otherwise what's the point?) What is the session to be used for? Well... For a shopping-cart actually :) But not the standard kind. I'm building a set of components that a webdesigner can use easily, without actually understanding how the code works. The webdesigner (my customer) wants to build a site where his customers can browse to some products and put them in their shopping-cart with simple code. Something like: HTML HEAD bla bla.. /HEAD BODY H1Buy this product!/H1 Pbla bla/P ?php include(functions.php); makeBuyButton(black shoes, size 34); ? /BODY /HTML I do the work with the variables and all, he only needs to make sure everything looks fine. I used to do this with Cookies, but they're evil :) Besides, a session-solution a much prettier :) I want to know if the session is maintained if he makes use of the components and has all his files extend on .php, when I have --enable-trans-sid on and (as noted in this mail) session.auto_start. I think this would work? I made a test-site locally, but I need to know the exact options that make this work, so I can inform the provider what to change (very helpful chaps over there, just don't know sh*t about PHP). -- Kind regards, Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] [Session] SID automatically add on all pages?
Thanks for the help guys. The one-line include is definitly a very good
idea, which I'll use.
Templating is very interesting, although, only if it works exactly as you
say, with HTML-like tags. I looked at Smart, patTemplate en some others,
but they all use {} or [] style tags. In that case, I prefer de php. If
anyone knows of a template-engine that can recognise the difference between
a custom-tag with and a HTML-tag, I'd appreciate the URL :)
For now, I'm going to make this work.
