Radicore v1.72.0
Apache Version 2.2.21
PHP Version 5.3.8
MySQL Version 5.5.16

1. Use updateSelection with multiple SET like this:

function _cm_post_updateRecord ($rowdata, $old_data)
{
$a = 1;
$b = 2;
$where = "'{$rowdata['lft']}'<lft AND rgt<'{$rowdata['rgt']}'";
$replace = "lvl='lvl+{$a}', lft='lft+{$b}', rgt='rgt+{$b}'";
this->updateSelection($where, $replace);
return $rowdata;
} // _cm_post_updateRecord

2. Doing the above will result in:

Fatal Error: Cannot extract token from: ', lft='lft+2', rgt='rgt+2'' (# 256).

3. Had to rewrite into something like below in order to avoid this fatal error:

function _cm_post_updateRecord ($rowdata, $old_data)
{
$a = 1;
$b = 2;
$where = "'{$rowdata['lft']}'<lft AND rgt<'{$rowdata['rgt']}'";
$replace = "lvl='lvl+{$a}'";
this->updateSelection($where, $replace);
$replace = "lft='lft+{$b}'";
this->updateSelection($where, $replace);
$replace = "rgt='rgt+{$b}'";
this->updateSelection($where, $replace);
return $rowdata;
} // _cm_post_updateRecord

Firstly, if you wish to increment a numeric column you must use "lvl=lvl+1" and not "lvl='lvl+1'". If you enclose the update value in quotes it will be treated as a string.

Secondly, I have made some slight code changes in the attached zip file which should help.
