[TYPO3-seminars] help please: paypal and seminarmanager

[G. Fahrenbruch]

hello,

does anyone has experience with integrating paypal in the seminars manager?
I read in the documentation, that there is a hook for that:

There now is a new hook for the list view. It's registered like this in
ext_localconf.php:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['seminars']['listView'][]

= 'EXT:seminarspaypal/Hooks/class.tx_seminarspaypal_Hooks_MyEvents.php:' .

'&tx_seminarspaypal_Hooks_MyEvents';

It's used like this:

class tx_seminarspaypal_Hooks_MyEvents {

/**

* Adds an "add to cart" PayPal button for non-free registrations that have

* not been paid for.

*
I didn't found out, how to get this running, and the seminarspaypal
extension which I found here

https://svn.typo3.org/TYPO3v4/Extensions/seminarspaypal/trunk/

 is not really finished, as far as i can see... and it is not in the ter
either.

are there any idea's or help for this issue?

thanks and greetings, gunda
