View only custom data field purpose?
April 29, 2010, 02:00:13 pm
I am trying to figure out the use for a View Only custom data field ... if the field is marked as View Only, then you cannot add any data to it either manually or using the API which makes it basically useless!

What good is a field that you cannot add any data? Or am I missing how it should be used!

Thanks

The description below VIEW ONLY? is:

    Is this field set by PHP code (via a custom hook). This field will not be updated by CiviCRM.

This field type is intended to be set via a hook. And of course hooks CAN set the value.

This is worded poorly because it starts with the word 'Is' like its asking a question ... I don't understand it ...
"Is this field set by PHP code (via a custom hook). This field will not be updated by CiviCRM."

Should it instead read: "This field is set by PHP ..." ??

Is there any docs on how to set it from PHP in a hook?

What about forcing the API to change it (currently API cannot create or update a view only field)?

I have used this hook: http://wiki.civicrm.org/confluence/display/CRMDOC/CiviCRM+hook+specification#CiviCRMhookspecification-hookcivicrmcustomFieldOptions to set the options for View Only custom fields. The other hook that should be able to do this is http://wiki.civicrm.org/confluence/display/CRMDOC/CiviCRM+hook+specification#CiviCRMhookspecification-hookcivicrmbuildForm

Ok thanks I will take a look at those!

EDIT: Ok, I took a look but I don't see how either hook lets me add/modify data in a View Only field? I must not be understanding how it is to be used or what it is for!

IMO, you should use:

CRM_Core_BAO_CustomValueTable::setValues

to set values of custom fields including hidden fields.

Will this allow you to set Custom fields that are View Only (not hidden) as well?

Thanks

yes, you can use CRM_Core_BAO_CustomValueTable::setValues
to set/update value for view only custom fields.

Is that the only way that a View Only field can be set/modified, or are there other ways as well?

IMO you can give default value at the creation which might going to work.
