Ok I found it, did it but I've made some tests and it doesn't work...
http://msurowiecki.netau....x.php/guestbook/entry/add - link to my site...
The file to edit is: components/com_easybook/controllers/entry.php
and the code to paste is:
* ADD NiK START
* We load the plugin group 'easy' and define an event 'onSubmitEasyBook'
//--Get reference to dispatcher
$dispatcher =& JDispatcher::getInstance();
$results = $dispatcher->trigger('onSubmitEasyBook', array(&$admins, &$temp));
foreach( $results as $result )
if( JError::isError($result) )
//--A plugin returned an error - hopefully it has displayed some message cause..
//--We will end here
* ADD NiK END
Why it doesn't work? I did everything like you showed. Should I see numbers and letters to enter when signing my guestbook?
