really odd error in wfsection 2.07 beta 3 code

So I finally figured out how to turn PHP debug on. I decided to roll back XOOPS to a point before I had installed the wfsection module (using a nice little perl script I made that copies XOOPS and the mySQL database for backup and allows me to revert to any previous version I want). Rather than go with version 1.01 of the module, which was generating lots of blank pages and is relatively old I decided to go with 2.07 beta 3, the newest version. I had tried it before but I had not been able to install it before for some odd reason it was making XOOPS freak out whenever I tried to go to the modules admin page. It seems there was some sort of fatal error inside the PHP code that was causing XOOPS to stop rendering HTML so I couldn't even see the module in the install list, nor could I see any module whose directories inode number was greater than the wfsection directory's. Now that I have PHP debug on I was able to shed some light on the problem. At first I was getting some redeclared variable errors inside of the wfsarticle.php file inside the declaration of the WfsArticle class. I commented out the redeclared variables (why they were left in there is beyond me) but then I came to this error:

Fatal error: Cannot re-assign $this in /engtools/local_advtech_develop/apache2/htdocs.xoops.v006/modules/wfsection/class/wfsarticle.php on line 591
Notice [PHP]: Undefined index: logopath in file modules/wfsection/class/common.php line 92
Notice [PHP]: Undefined index: logopath in file modules/wfsection/class/common.php line 93

Here is the code in surrounding the error:

585 function getArticle($articleid)
586 {
587 $sql = "SELECT * FROM " . $this->table . " WHERE articleid=" . $articleid . " ";
588 $array = $this->db->fetchArray($this->db->query($sql));
589 if (!is_array($array))
590 {
591 $this = false;
592 return false;
593 }
594 $this->makeArticle($array);
595 }

This error is a bit much for me to handle without serious understanding of what is going on. I don't feel comfortable trying to change any of this code as I don't want to break it more than it already is broken. Does anyone know what this error means exactly? Has anyone else even encountered this before?

youre running php5? im not sure, but i think in php5 you cannot redeclare a variable representing a object *inside* this object.... like "$this", in this case. Im running the last wfsections without any problem in php4

better than that... (at least for me - i cant run perl on my server lol) can you tell us how you implement that? specially the part os "revert to any previous version".... maybe i can reproduce this script in php. but if you could share the script, it would help a lot!

Forgot to mention, you'll need to change some things in the script to fit your own system, like the group name and the MySQL user and whatnot, nothing too hard to figure out.

The problem is that this version of WF-Sections is not PHP5 ready, with PHP5 $this is basically only used within classes etc (It's reserved so to speak).

I am close to releasing a version that should work on PHP5 without any problems and without those little clitches you mentioned already.

I just installed this version 2 days ago, it worked fine till I found out that I suddenly had white pages members modul, after clicking on a member and in the wffaq modul.

xoops2-mod_wfsection_v2_01.zip .

Has anyone got a version (link) here to a version that is running stable on xoops2.0.10 without errors ??

Thank you.

Or post me a solution how to get rid of the blank pages as the module wfsection itself is running ok so far.
