Hook after Paypal Payment

[Franco]

Hi,

I know there are a bunch of posts out there about this, specially about using hook_civicrm_postProcess but I couldn't get that to work.

Goal:
Basically I need to change the membership end date after a successful payment.
(ie. if paid in NOV or DEC add a year and end next year on DEC 31), otherwise(before NOV) leave it to end on DEC 31)

Additional Info:
BaseIPN uses  'end_date' => CRM_Utils_Date::customFormat(CRM_Utils_Array::value('end_date', $dates), $format),
to set the date. but this just overwrites any changes I make before.
I tried passing in a $_Session variable from my module into BaseIPN but that didn't work either.

1. i'm assuming u r using paypal ipn and hence the postProcess hook does not work

2. can u add code in the _post hook of the membership object. So u can modify the end date there?

in general, hooks are fairly low level and making high level changes are not trivial at times

Thanks for the quick reply!

1. Yea thats definatly why

2. Not sure what exactly you mean, could you please be a bit more specific.

Another approach was to modify the BaseIPN file itself.. but im not sure how exactly to debug thatm since the normal die or vardumps don't show anything after the payment.

Check

http://wiki.civicrm.org/confluence/display/CRMDOC/Hook+Reference

The postProcess hook is a form hook. The pre & post hooks are DB hooks - called before & after the membership is saved

I used the pre hook before but that only gets called before it goes to paypal.
There is no call to this hook after the payment has been successfully received.


Also it seems if I change the end date in the _pre hook then the BaseIPN file changed the date again.
I tried with _post and it works the same way.

Here inside BaseIPN:

Code: [Select]

$formatedParams = array('status_id' => CRM_Utils_Array::value('id', $calcStatus, 2),
              'join_date' => CRM_Utils_Date::customFormat(CRM_Utils_Array::value('join_date', $dates), $format),
              'start_date' => CRM_Utils_Date::customFormat(CRM_Utils_Array::value('start_date', $dates), $format),
              'end_date' => CRM_Utils_Date::customFormat(CRM_Utils_Array::value('end_date', $dates), $format),
            );
Getting rid of the last line in this array solves the problem but again I would want the date to be changed only after payment has been received.  So this would not work.

did you see if this hook will work for you?

[Franco]

Decided to just modify core using a custom php directory before I found out about,

hook_civicrm_alterPaymentProcessorParams( $paymentObj,&$rawParams, &$cookedParams );

Will try that again in the next phase of our project, and see if I have any luck.
Thanks for the reply though!

If the membership post hook is not being called in this work flow then that should really be fixed in core

[amitbhoria]

if the hook is not working after the payment to change the join,start and end dates of membership then you should make a change in contribution BAO file, well it worked for me ...
