[PHP] Another Session Question
There is a little code that worked before my virtual host before they
updated to 4.3.1.
First time the function is called session should be set, subsequent
calls should be skipped.
session_start();
if($_SESSION['counter_file'] !==$counterFile)//See if
visitor has already been counted for this page
{$num += 1;
$_SESSION['counter_file'] = $counterFile;
}
echo $_SESSION['counterFile'] . ' testx ' . $counterFile;
$_SESSION['counterFile'] shows nothing, even the first time through
$counterFile shows just fine.

might just be a typeo but do you mean: echo $_SESSION['counter_file'] .
' testx ' . $counterFile;
instead of this: echo $_SESSION['counterFile'] . ' testx ' .
$counterFile;

Re: [PHP] Another Session Question
Your'e right, that's a typo.
If I put a
echo $_SESSION['counter_file'] .
' testx ' . $counterFile;
Before and after the conditional, $_SESSION['counter_file'] is set after the conditional, as it should be. But, it is gone from the before echo when the function is recalled.
The Session buffer looses the value.
session_start() is called again before returning to the function; but, I thought repeated session_starts() were ignored and thus should not restart the session.
I use the session buffer extensively in other places without any problem.

[PHP] Another Session Question
Hello all,
I have php ver 4.1.1 running with register_globals() ON on my site. I
am trying to use sessions to maintain state during a visit to the site.
I have read thru the manual, but my mind is still cluttered with
doubts. I understand that use of the $_SESSION global array will
greatly add to the security of the site and will prevent variable
poisoning.
How do I register a session?
The manual (http://www.php.net/manual/en/print/ref.session.php) says
that there are 2 methods:
Example 1. Registering a variable with $_SESSION.
?php
session_start();
// Use $HTTP_SESSION_VARS with PHP 4.0.6 or less
if (!isset($_SESSION['count'])) {
$_SESSION['count'] = 0;
} else {
$_SESSION['count']++;
}
?
---
Example 4. Registering a variable with register_globals enabled
?php
if (!session_is_registered('count')) {
session_register(count);
$count = 0;
}
else {
$count++;
}
?
-
This is a snippet of the code that I am testing:
? session_start();
require_once('../Connections/MasterStream.php');
if ( $_POST['validuser'] ($_POST['password']) ) {
mysql_select_db($database_MasterStream, $MasterStream);
$query_Recordset1 = SELECT * FROM `admin` WHERE `admin`.username =
$_POST['validuser'] AND `admin`.password = $_POST['password'];
$Recordset1 = mysql_query($query_Recordset1, $MasterStream) or
die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
if ($totalRows_Recordset1)
{
echo Success!br;
if(!isset($_SESSION['validuser']))
$_SESSION['validuser'] = 0;
else $_SESSION['validuser']++;
}
else{
echo Please try again laterbr;
}
}
?
Thanks in advance,
Pushpinder
Re: [PHP] Another Session Question
So does your code work? Here's a tip: Try a simple example, like what's in
the manual, and see which method works for you. If they both work, which one
do you understand? Use that one...

[PHP] Another Session Question
I've seen various tutorials on sessions where they specify the session id instead of just using one generated by php ! Why ? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Another Session Question..
I asked a question the other day about turning $_REQUEST variables into
$_SESSION variables...thanks, all who helped me with that...
I have another question about assigning $_REQUEST variables to $_SESSION
variables that I am hoping someone can help me out with
Here is a snippit of code...
while($r = mssql_fetch_array($result)) {
$vname = $group_abbr . $count;
$_SESSION[$vname] = $_REQUEST[$vname];
}
Now an explanation...
$vname is the actual name of the variable that is stored in the $_REQUEST array
(and what I want it to be called in the $_SESSION array) can I do this: ? (for
example, a1 so $_SESSION['a1'] = $_REQUEST['a1']; is what I want it to do...but
I need to send the name of the variable as a variable...)
I tried this...
$_SESSION[$vname] = $_REQUEST[$vname];
...but it doesn't seem to be working and I can't figure out how to get those
variables registered
Any help is much appreciated.

RE: [PHP] Another Session Question..
What I am trying to do is register a variable already in the request array...as
a session variable.
I know I can do $_SESSION['foo'] = $_REQUEST['foo'] but that's if I know the
name of the variable that was registered on the form side I do know the
name, but it's dynamically generated.
So for example, the name could be foo1 - foo10 and I want to register all of
them as session variables.
So I want to be able to do this:
$count = 1;
$varname = foo . $count;
then do this:
$_SESSION[$varname] = $_REQUEST[$varname]
where the value of varname is actually the name of the variable that I want to
pull outDoes that make any sense?
I don't think that I can do $_SESSION['varname'] = $_REQUEST['varname'] in this
case because I don't want the value of varname as a session variableI want
the value of the value of varname as a session variable.
I'm not sure if I can do this...but I'd assume there has got to be some way, I
just don't know what it is.
Also, apparently the php manual warns not to use $_SESSION['var'] = $var with
session_register and session_unregister. So that wouldn't work for me anyway.

If you are trying to register any variable... Say $foo...
Session_register('foo');
It will automatically appear in the $_SESSION array next time a page is
requested. I'm pretty sure it even will do it immediately (put it in
$_SESSION)

RE: [PHP] Another Session Question..
On second look, perhaps it is working correctly.
I wasn't incrementing my counter variable. Sorry to flood your mailboxes.

this should work as well;
foreach($_REQUEST as $key = $val) {
$_SESSION[$key] = $val;
}
