One side will create a new military technology that trumps the other’s latest foothold, then the new underdog will put all their R&D money into thwarting this new tactic until they have something that overcomes it. China has been working on anti-stealth technology for years, you know.

Right now it is pretty easy to trick spambots, but there are some major advances occurring with AI. And I expect it to boom within the next 10 years. The singularity is near, you know.

I actually had no problem finding all the good places to add the code I required. While your code is not super-well commented, the design is clean and simple, and you used descriptive filenames for your includes.

I did not notice that session_start() at the top of the header (actually, I don’t think I even opened the header until now). But, as you say, I don’t think the query string identifier will ever become an issue. Now, OCR spambots, that will be a problem.

I tried to comment this project as well as I could, but it gets tedious when you are the only one working on it.

By the way, Mirthcanal does use sessions, but the session id is not in the GET array. In the header include, the first line of every page is “start_session();”. So you could use that, theoretically.

But I don’t think the issue you described above will become a problem. I would be more worried about AI becoming advanced enough for spambots to read the catcha’s. And then EVERYbody’s in trouble.

That shouldn’t be too difficult to handle anyway.

If you modify the lines around

if ( $cas_bgcolorset == "white") {

and set the

$cas_bgcolor = array ( r , g , b )

you can set the background color.And if you change (or remove) the

switch( $cas_bgcolorset )

and set the

$cas_textcolor = array( r , g , b )

that’ll take care of the foreground color.

PS. But… there’s always a but… yah, I just might wish you could set it to use one single custom text/background color with HEX code instead of having to choose between two colors or 10 random colors…
