Re: [PHP-DB] Sessions help needed !!!
Well, not much to go on, but I'd check variable scope, and register-globals. The latter being more likely as I can't see how the scope would change if you're just copying things over. -Micah On Friday 17 February 2006 2:18 pm, Chris Payne wrote: > Hi there everyone, > > OK this script worked perfectly on my own apache webserver and I had to > move it to the main live server, but for some reason it's not passing > session values in the same way and i'm positive it's something damn > obvious. > > On my server I can use: > > echo $credits_system; > echo $credits_left; > echo $foldername; > > To display the information to make sure it is being passed, but it returns > blank on their server (Same versions of everything except I didn't install > it so it may have something turned off in the config - which i don't have > control over, sigh).

Re: [PHP-DB] Sessions and MySQL?
Cheers to everyone...
the curly brackets was me not thinking after a boozy lunch, and trying to
recreate code, on an E-mail..
anyhoo...
I thought the best idea, and the simplest for me, was to remove the ' from
the session recall
Turning $_SESSION['salutation'] --> INTO --> $_SESSION[salutation]
Cheers all...
it's clear as day now...
aint it always the way eh?

Tristan,
yes, You are alternating between curly braces {} and parenethes ()
(spelling??). Also you forgot to the closing double quotes when
completeing the mysql_query statement.
You could also put the insert statement into a vairable and echo that to
the screen. That way if you can't see the error, paste the query text
into the mysql command line client.

Eeek, didn't notice your brackets. They're a bit messed up as well.
mysql_query("INSERT INTO $table (salutation, name, city)
VALUES (\"".$_SESSION['salutation']."\", \"".$_SESSION['name']."\",
\"".$_SESSION['city']."\");");
This MIGHT work :-)

In addition to what John suggested, I see you have switched from parens to
curly braces when you close your list of columns and list of values. AFAIK,
you need to use parens to contain those lists.

Well, the error message really says it all, it's just worded a bit opaquely!
Basically, setting a cookie uses an HTTP header, and all HTTP headers have to be sent
before your actual page content -- and the error message is saying that you can't send
an HTTP header at line 10 of your script, because you started outputting your page
content at line 8.
> Warning: Cannot send session cache limiter - headers
> already sent (output started at
> /var/www/html/prueba/index.php:8) in

Same thing, but for a cache limiter header.
You need to re-order your script so that the header requests come before the start of
real output.
Cheers!

Re: [PHP-DB] Sessions Vs DB Access
Quick hack for those who think that the MM handler is not stable is to use the standard handler and the directory where the session files will be to be mounted as tmpfs (even /tmp).

Re: [PHP-DB] Sessions Vs DB Access
Don't forget that you can use the DB to store PHP Sessions as well, which is faster than storing the sessions in /tmp on the file system. If you have well written SQL, you can have 5-30 queries per page, most of which should return the data in under 1/100 of a second. I was running a site doing 150 queries per second, serving 1M page views a day. That's about 13M DB queries per day at a rate of about 11-12 page views per second. All on a dual 800mhz and 1gb of memory on FreeBSD, Apache, PHP and MySQL. It can be done!

Re: [PHP-DB] Sessions Vs DB Access
Chris, I'm assuming you're running this thing on *nix. Session variables are stored on the file system. PHP writes them out to /tmp, where it subsequently reads them upon request. The question is: How good at caching is your DB? If it can cache common select queries, then you are probably better using the DB (since file system caching is usually not that great). If your DB is busy with other things while the file system is relatively idle, maybe it'd be better to store them in sessions. The only real way to know is to benchmark both methods. You could come up with some real quick code that implements both methods. Then, run ApacheBench (ab) or JMeter to test the performance. Be sure that you run the benchmark utility in such a way to use the session vars (ie, simulate a user login). During the tests, watch things like load average (top) and I/O activity (iostat). Let us know which method works best for you. Scalability issues are so cool. --Dave Chris Payne wrote: Hi there everyone, I have a system I am programming, and each page needs to get various config elements from a DB, of course this means lots of DB access for each page. What I was wondering is, after the user has logged in successfully it currently stores their email, name, address and a few other bits of data in a session, would it also be a good idea to store other information in a session at the very start when they login to ease DB access? Are there problems with having lots of data in a session? Well when I say lots of data, I mean things like font size, color, table images, background colors, some normal text etc nothing like an essay or anything, just about 30-50 different variables. Just want to make sure it won't slow my system down by doing this, or would it speed it up because of less DB access?

Re: [PHP-DB] SESSIONS
Do this instead:
$user = mysql_fetch_object($sql_result);
$_SESSION['user'] = $user;
Then, you can use stuff like:
print "{$_SESSION[user]->name}";
// or if register_globals is on
print "$user->name"; // which is nice because you don't have to {} the var or
".$var[name]."

You sould register sessions first, and if have been registered, are passing with session_start() in each page at the top, before the tag..

My only thought is, where are you trying to start your session in the frames? Are you trying to start the session in the "hidden" frame or in one of the visible frames?

I also suppose that something is printed before Header() function. Suppose, that you have code: I such a case NO BLANK characters are allowed after closing "?>" in included "xxx" file.

RE: [PHP-DB] Sessions and Frames
The manual says... Remember that the header() function must be called before any actual output is sent, either by normal HTML tags blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that will output before header() is called. The same problem exists when using a single PHP/HTML file. So, an example of what it's complaining about below leads me to believe that you've already written some ouput to the browser which effectively ends any possibility to do any HTTP HEADERS.

Hi, Every different page in a framset is loaded separatly so the only thing you should be aware of is not to output anything before the session stuff.

if you just want to refresh same page, then there shouldn't really be a need, if you just do something like or, if you mean refresh to another page, then you could use the second one could also be used to send the location back to this page, but make sure you do something conditional to keep the user out of an endless loop :) // -Original Message- // From: DC [mailto:[EMAIL PROTECTED]] // Sent: Monday, 7 May 2001 12:42 PM // To: [EMAIL PROTECTED] // Subject: [PHP-DB] sessions and page refresh? // // // Hi All // // I have a call to session_destroy(); // // This works // // But I also want to refresh the page as well. // // So onclick of button // // 1. session_destroy(); // // 2 refresh page. // // Any help or ideas are welcome as always // // Thank you in advance // // Dave C // // // // // // -- // PHP Database 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] // -- PHP Database 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]

when you build the string for the ahref just insert the value of $topidID
like so
echo 'link name here';

Re: [PHP-DB] Sessions ???
For this operation there is dire need for session management.
And remember the default variable order EGPCS may cause you trouble if
you're sending a put variable across with the same name as a session
variable. Session vars take presidence in the global scope.
http://localhost/forums/view.php?topicID=3
The session var $topicID will override this put variable.
$topicID=session var value //your 3 may not be here.
$HTTP_GET_VARS["topicID"]=3 //you can still find your 3 here.
Session variables are good for maintaining information from one page to the
next, avoiding the need for the client to keep sending the same information
over and over again.
In either event, I recommend useing a different session variable name than
the put variable's name, unless you use $HTTP_GET_VARS/$HTTP_SESSION_VARS
accordingly.

Dave,What you need to do is make sure that the
variable: $topidID is being set to a value first (before you register it
you must get it from the table. Once it is set you need to register it as
you did BUT WITHOUT the $. So it will
say:session_start();session_register("topidID");?>Make
sure that session_start is ALWAYS before any headers in your html page,
BUT register does NOT have to be. It can be declared anywhere in the page
as long as you have set the value in it already. Also, on every page that
will ever access topidID you must have session_start() at the top. But not
session_register, as the value has already been registered. HINT: if you
want to change the value of topidID just set it's value and then call a
register right after you do that. Hope this
helps!>>> "DC"

Re: [PHP-DB] sessions and page has expired warning
Hi!
I had exactly the same problem and i found the script that does the job.
At the begining of your script write this:
if ( $rd == 1 )
{
$tmp_str_store = "var_list_str";
session_register ( "$tmp_str_store" );
$$tmp_str_store = "";
foreach ($HTTP_POST_VARS as $k => $v)
if ( is_array ($$k) )
foreach ( $$k as $ar_k=>$ar_v)
$$tmp_str_store .= $k."[$ar_k]=".urlencode($ar_v)."&";
else
$$tmp_str_store .= $k . "=" . urlencode($v) . "&";
}
header ("Location: this_script_path?rd=2" );
exit;
}
else
if ( $rd == 2 )
if ( isset($var_list_str) )
parse_str($var_list_str);
in the HTML body write
and vualya you will not get message like you describe NEVER!!!

Re: [PHP-DB] sessions and page has expired warning
Here, I think you may be over - using session variables a bit...have not used them in php, as I have version 3, which doesn't support them. However, by day I am an ASP developer, and article after article I read warns about session variables! They are great, but can hog memory, especially if you have many users concurrently, so I would use them sparingly, just when you have to. The "back" button problem - here is where a session variable might be usefull, if you want to force a particular order of website traversal and not allow them to go back - when leaving, say page 1 - set a session variable $visitedPageOne = true On the top of that page, first thing - check for the value of $visitedPageOne, if true, redirect to the next page, ect.
