Blocking Words Modification

Carbonize,

I think I remember reading either here or on the Lazarus GB that either newer versions of AVG and/or Lazarus have the ability to block certain words from being posted (not just censor but actually block the poster from posting). I wanted to try this as another method of blocking spam (I remember you said on your site that links could be blocked with this mod and I figured out that my normal spammers use certain words that I can block w/o hurting the entries from true guestbook signees).

If you remember me, I am the person that uses AVG with phpWebSite and currently cannot update from 2.3.1. I can however, modify some things with the version I have and I was wondering if the block mod can be applied to 2.3.1?

If you or anyone else could help me out, I would greatly appreciate it.

The mods for AG will be easy enough. I will toss something together tomorrow.

Wow, thank you Carbonize! I may not be able to update my version for awhile, but I will have a well-modded version to suit my needs nonetheless.

I really appreciate that.

THIS IS NOT TESTED

I made the modifications.

When I tried to sign the book with an entry using the censored words, I got the following message.

view plain copy to clipboard print ?

Fatal error: Call to undefined function: query() in /class/vars.class.php on line 269

Is this what I am supposed to get (including it showing the full path of my folder) or something else (I assume something else)?

Did you put $this->query and not just query ?

I didn't make any other changes other than the ones you told me to make. Should I make that change and then let you know what happens?

**edit**

$this->query was already included in the original changes you suggested.

OK my mod is fine it's just that you are using a modified version of Advanced Guestbook and so I have emailed you the required change.

I'm still getting the same error.

Thank you Carbonize! The blocking word mod works. Please consider this problem resolved.

Thanks for posting this turn-around for the "Blocking Words Modification".

I am great fan and user of AGB and by reading through some of the major topics I have learnd a lot and solved many problems (without asking a single question my self).

I host a Guestbook for a Gospel Choir and due to your support we now have a clean Guestbook (hopefully)!

It's a far better way to prevent SPAM by blocking then rather by replacing bad words with symbols like "#@*%!".

MAY GOD BLESS YOU ALL
