I get an error for line 58 in as_snipercaptcha.php for the line:

if($this-b_buffered) return $ret

php (5.0) errors with:

PHP Fatal error: Using $this when not in object context in /home/www/sniper/as_snipercaptcha.php on line 58

Any ideas?

You did not show your code. Anyway, I think You use "static" call CSniperCaptcha::DrawRefs(). So any $this references are invalid.

You should create new object $captcha = new CSniperCaptcha(),
and use $captcha->DrawRefs();

Hi!
I have also an error when starting this script.

I have downloaded the package and unzipped in my server and then launched sample.php to check if all is ok.

I get this:

As_SniperCaptcha using sample

Fatal error: Using $this when not in object context in C:\ZMWS\_web.zmwsc\captcha\as_snipercaptcha.php on line 58

.. and all stops..

Any ideas to solve this boring answer?
Thanks!

I've fixed this issue, so I hope DrawRefs() now can be called as static method, CSniperCaptcha::DrawRefs().
(BTW, I didn't see this problem on my PHP 4.3.x and 5.2.x environements.)

Yes it works now!! Thanks for the fix!

Just a last question: The squares looks very small on my screen and I think that for bad eyes users, it would be difficult to click on the correct boxes.

Is it possible to increase the global size of the boxes? I see the command $captcha->Draw(8,3,12); in the code. 8 and 3 are the number of horizontal and vertical boxes, but what is 12?

I would like to display the double size as the current one.

Thanks for reply!

3-rd parameter ($cellsize) is a cell size in pixels. If it's omitted, the size height is random number in a scope 10...20, and cell width - random in a scope of cell.height...height+10.
So You can use 3-rd parameter $cellsize to set your cell size. It's described in doc (htm).
