Custom-Data-Helper

Helper class for CiviCRM Extensions

This class can be copied into any CiviCRM extension to facilitate creating, updating and deleting custom data. It is therefore a close realtive to CiviCoop's config items.

Disclaimer: This is still under development. Current functionality:

• CustomGroup/CustomField data
• OptionGroup/OptionValue data
• General entity data

Instructions

1. Copy the CustomData.php file into CRM/Yourextension of you extension
2. Rename the contained class to CRM_Yourextension_CustomData
3. Create a resources folder and create a resource JSON file. Take a look at the examples in this extension
4. Add the following lines to your civicrm_enable hook:

require_once 'CRM/Yourextension/CustomData.php';
$customData = new CRM_Yourextension_CustomData('my.extension.domain');
$customData->syncOptionGroup(__DIR__ . '/resources/my_option_group.json');
$customData->syncCustomGroup(__DIR__ . '/resources/my_custom_group.json');

JSON Format

The data in the JSON resource files reflects the data as used by the API. Fields starting with an underscore ('_') have a special meaning and are not passed on to the API:

• _lookup: this takes an array of field names that are used to identify the entity in the system. Based on this lookup it will be decided whether the given entity is updated, or a new one is to be created.
• _translate: this takes an array of field names where the values are passed through ts() translation before being passed on the the API. The domain is passed on as well. Caution: due to the inexplicit syntax the ts parser won't pick up those strings and they have to be added to the POT file manually.
