[PHP] session variable problem
Very rusty with PHP. We moved our web site to a new hosting service (godaddy). PHP changed from 4x to 5.2.17. I can no longer change $_SESSION variables after the first use. First call to form - start session create variables Second call - can read variables, change existing ones (but they do not persist to next call) - cannot create new variable without an error Using $_SESSION['varname'] always session.auto_start off register_globals off session.use_only_cookies off I assume this is setting difference but I can't seem to find it. -- Mark B -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

?php if(!isset($_SESSION)) {
session_start();
}
if (isset($_POST['lend_fname'])){
$_SESSION['lend_fname']=stripslashes($_POST['lend_fname']);
}
if (isset($_POST['lend_lname'])){

$_SESSION['lend_email']=stripslashes($_POST['lend_email']);
}
if (isset($_POST['lend_phone'])){
$_SESSION['lend_phone']=stripslashes($_POST['lend_phone']);

?
On the first page, Now what happens is it only sticks to the first two
(lend_fname and lend_lname), the others still get lost. Any idea how or why
the exact code works differently?

Are you checking to see if the post variable is set in the code that handles
saving the form values to session variables? I can't tell if you're doing
this from the code you provided. If not, it's possible that when you are
returning to one of the earlier pages, you're attempting to again save the
form values even though the corresponding $_POST vars are empty. This would
cause visiting page 2 to essentially delete the data previously posted from
page 1.
Using your example:
// Only save if post variable present, which means
if (isset($_POST['lend_fname']))
{
$_SESSION['lend_fname']=stripslashes($_POST['lend_fname']);
}
Also, some users will likely click the back button during the process, which
brings up a funky message. You might try building one page that is
dedicated to saving all of the session variables, which then redirects to
the corresponding next page in the process.

Thank you for your reply.

No, I not done anything about the post variable, frankly I thought the
session variable would cover it. I tried your code
if (isset($_POST['lend_fname'])){
$_SESSION['lend_fname']=stripslashes($_POST['lend_fname']);
}
And it seems to work fine, the data seems to stay. Is there an easier method
(perhaps putting the post or session variables into an array?
Again thank you for your reply and your solution.

The session variables store what you tell them to store. The way your pages
were set up, it sounds like you always called the code that set the session
variable, even if the session variable was already set and even if there
were no POST variables sent.
People often do use sessions to preserve the state of a form's fields if the
form has multiple pages, just as you are doing. In this type of situation
someone can be visiting a page to 1) submit new data (POST data is present
such as when somebody clicks on the submit button in the previous page), or
2) review the data they've already entered (no POST data present, such as
when somebody uses the navigation on your page.) You have to check to see
which of the two possible types of page requests is occurring.
Using the code you have, you can probably just wrap the code that you have
that sets the session variables in an if block that checks for one of the
post variables you're expecting.
I'd recommend reading a tutorial or two on how PHP sessions work, such as
the following:

Re: [PHP] session variable problem
The reason for the fatal error is that you can only store the sessions in three (or four) ways, files, in a database or in the memory. What variable has no value? Have you started the session before you try to access the values? session_start(); echo $your_value; (Or preferably) echo $HTTP_SESSION_VARS["your_value"]; Here is a little code for you to test if you can read the session variables: session_start(); while(list($key, $val) = each($HTTP_SESSION_VARS)) echo "Variables name: $key - The value: $val"; } "SERKAN BALKANLI (EBÝ Bþk.-Analist Prog.)"

Merhabalar,
firstly do you use windows or linux?
id you use windows you shoul give the session_save_path to the script. (
session_save_path("c:\\user\\tmp"); )
if you use linux and no changes in your .ini files, your sessions store
in /tmp
directory...
?php
session_start();
$id = 123;
session_register('id');
?
html
head

?php
echo $id;
