Hi, please let me know the topic with not English explanation, I will take a look (there was some but in such topic, I think, there was not guide how to do it, only the place where the captcha class is stored)

I didn't such modification yet, so cannot give any advice there, but if you think some article describes it, just let me know the article, so I can see it and tell you: it describes it or not. If it will describe it and I will be able to understand it, I will translate it.

Ahoi Jan,

what's written in this thread?

Code: Select all

I understand so far, that you have to change some code? I guessed it's only a kind of a definition (lenght)...

If you need to modify the captcha image (e.g. lenght of characters), you need to modify this file:

components/com_phocaguestbook/helpers/phocaguestbookcaptcha.php

there is a captcha class where you can change the output of the captcha.

The topic does not say how to do it. Because I didn't do such modification yet, have no experiences with this

So the only usefull advice is the name of the file where the captcha is located, there the number of characters needs to be modified.

I found the solution to this problem ... in

Code: Select all

components/com_phocaguestbook/helpers/phocaguestbookcaptcha.php

go to line 503
your modified the number 6

Code: Select all

$rand_char = PhocaguestbookHelperCaptcha::generateRandomChar(6);

Just that...
