PHP suddenly behaving funny with session.

9 Feb 2003

      I am confused here.

I have been playing around with php for a while and I have created soem
demo and test stuff that worked fine.

In the mean time php was upgraded and today I tried some of teh pages I
wrote and it does not work anymore.

Seems like variables are ignored as soon as I use session stuff.

I checked my php.ini file and everything is correct as far as I know.

SuSE 8.1

Installed packages:
-------------------
mod_php4-core-4.3.0RC2-0
phplib-7.2d-520
mod_php4-4.3.0RC2-0
phpdoc-4.0.6-222
apache-example-pages-1.3.26-57
apache-1.3.26-57

Here are an example:

If I comment the two session lines (session_start and session_register)
then the '$form[comment]' and '$actionflag' variables keep their values,
but as soon as any one of those lines are uncommnted, teh variables
loose their values, even though they appear in the URL.

Any idea what will cause this?

bybellib.inc:
-------------
<?php
session_start();
session_register( "session" );
// ---------------------------------------------------------

function writeLog( $message )
{
  $filename = "testlog.log";
  $fp = fopen( $filename, "a" ) or die( "Could not open testlog.log!" );
  fputs( $fp, $message."\n" );
  fclose( $fp ); 
} // writeLog
// ---------------------------------------------------------

function addKeyword( $keyword )
{
  writeLog( "addKeyword: keyword = $keyword" );
} // addKeyword
// ---------------------------------------------------------

add_comment.php:
----------------
<?php
  include("bybellib.inc");

  if( isset( $actionflag ) && $actionflag=="add_comment" )
  {
    if( empty( $form[comment] ) )
    {
      $message .= "No comment entered<br>\n";
    }    

    if( $message == "" )
    {
      $message = "Comment = ".$form[comment];
    }
  }
?>

<html>
<head>
<title>Add Comment</title>
</head>

<body bgcolor="#F1E4A4">
<?php
  include("publicnav.inc");
?>

<h1>Add Comment</h1>

<?php
  if( $message != "" )
  {
    print "<b>$message</b><p>";
  }
  // Debug
  print "<b>actionflag = $actionflag</b><p>";
?>

<p>
<form action="<?php print $HPH_SELF;?>">
<input type="hidden" name="actionflag" value="add_comment">
<input type="hidden" name="<?php print session_name() ?>"
  value="<?php print session_id() ?>">

Keyword:
<input type="text" name="form[comment]" value="<?php print
$form[comment]?>"><br><br>

<p>
<input type="submit" value="Update">
</p>

</form>
</body>
</html>
