Operating system: Solaris SunOS 5.9
PHP version: 4.3.1
PHP Bug Type: Session related
Bug description: sessions not overwritten properly
Description:
------------
Data that is newly written to the session hash is not getting stored
correctly. If I am storing two pieces of data (a string and a type of
view for example) in the session hash, the hash should only contain the
latest values of those two variables. Instead, as in the example
provided, the form randomly changes between the views, and the data shown
is not always the latest in the hash. Usually, it is from previous
submissions.
This seems to be a problem in IE and Netscape, but not in Mozilla.
Reproduce code:
---------------
<?
session_cache_limiter('public');
session_start();
if (isset($_POST['submit'])) {
$_SESSION['data']=$_POST['data'];
} if (isset($_GET['form'])) {
$_SESSION['form']=$_GET['form'];
} if (!isset($_SESSION['form'])) {
$_SESSION['form']='basic';
} if ($_SESSION['form']=='basic') {
echo 'The value of the variable is '.$_SESSION['data'];
} if ($_SESSION['form']=='advanced') {
echo 'Here is a complete dump of the session hash ';
var_dump($_SESSION);
}
?><br><br>
<a href=bug.php?form=basic>Basic</a><br><a
href=bug.php?form=advanced>Advanced</a><br>
<form method=post action=bug.php>Data: <input type=text name=data
value="">
<input type=submit name=submit value=submit></form>
Expected result:
----------------
When you type in a value, it should appear. When you switch views, the
data value should stay the same, only the view changes. When you enter
different data, only the data changes, the view stays the same.
Actual result:
--------------
View randomly changes and data is not always last entered.
