CiviCRM Community Forums (archive)

I have some events in civiEvent where I have added a custom group and field for a contact (i.e. project leader).  By Default when the event info is shown it shows the contact's name only.  I would like this to also show their phone number and e-mail address along with their name but only have to enter the contact on the event (i.e. not duplicate phone and e-mail).

From what I have gleaned from the forums it sounds like this might be possible using civiCRM hooks...  Any insight or direction on how this might be accomplished?  (i.e. show extra contact info along with the Contact's name in event info).  I have no issue with adding the custom field for the contact... just want more data shown in the event info.

Thanks,
Greg

Greg,
Did you consider using the built-in event contact Email and Phone fields (which are displayed on the Event Info pages). You configure those from Configure Event >> Event Location tab.

lobo,

Here is my status so far:
1) I have the custom hook implemented and can capture the Event Info Page. 
2) I also can get the eventID by using $page->get('id');
3) I have recognized that the EventInfo.tpl uses the CustomDataView.tpl to output the Contact Info

I know how to manually get the answers from the DB but was thinking a cleaner approach was to use the hooks, template overrides, etc. but not sure where exactly to go from here.

I know I need to learn up on Smarty Templates to better understand the .tpl files.  For instance on the CustomDataView.tpl file I need to dig into the $element item to find out what it knows... and what else I need to populate from the custom hooks for the template to know.  Then I also need to figure out if I change such a deep template what other areas am I affecting, possibly adversely.

To continue on and get the Custom Field ID and matching value for the desired fields should I load up the BAO Custom group File and proceed from there.

I took a look at hook_custom.   The documentation is a little unclear about when the hook is called, but it seems there would be times when we would want it called as the custom field is retrieved, not just when it is edited or saved.

For example, you might have a custom field whose value depends upon a number of things that change dynamically, outside of the scope of the group to which the custom field belongs.

Here's a contrived example.  When we look at a member's contact info, we want to calculate, on the fly, how many trouble tickets he has open in our system.  It's easy enough to define a custom field labeled "Open Tickets"., and to write code that retrieves info from the database and makes a count.   But displaying an up-to-date value means we want that custom code to run every time the custom data group is retrieved, not when it is created, saved, or edited.

I understand that I could calculate the value in page_run, but localizing it to hook_custom seems like a better idea.

Just a quick note to say thanks for this posting. I just wrote my first custom civicrm hook and it's working delightfully.

Overall, i found the documentation of the hooks a little too technical - but probably just because I hadn't read any examples. The pageRun hook is a good one.
