[phplib] db_mysql 'uninitialized array index (1)' error when starting new session From: Fred Yankowski (fred <email protected>)
Date: 11/13/00

I just upgraded to phplib version 7.2c and now I'm seeing error
messages like this when a session first starts up:

         Warning: Uninitialized array index (1) in db_mysql.inc on
         line 228

It looks to me like the ac_store() method in CT_Sql is trying to read
row data after a query without ever having done next_record() to get
the row. Not only that, it's accessing the 1 column when (to my
understanding) it should access the 0 column.

Here is a PHP3 file that demonstrates the problem. (The session class
name is slightly different in my real test code): 

--
	<?php
	include("prepend.php3");
	page_open(array("sess" => "Example_Session"));
	error_reporting(63);
	print("Hello");
	page_close();
	?>
--

And here is a patch that fixes the problem, in my configuration anyway:

*** ct_sql.inc  2000/11/13 16:08:18     1.1.1.2
--- ct_sql.inc  2000/11/13 18:26:29     1.2

          && $this->db->query($squery)
!         && $this->db->f(1) == 0
          && !$this->db->query($iquery)) {
  
          $ret = false;
