Fill Address/Phone enityRef

Question

I'm writing an extension to customize the create new activity page. I need to add the 'With Contact' address and phone number to the page. When editing the /civicrm/CRM/Activity/Form/Activity.php how do you get the address to propagate when the contact is selected? Here is what I'm trying to edit:

    ),
   'target_contact_id' => array(
   'type' => 'entityRef',
   'label' => ts('With Contact'),
   'attributes' => array('multiple' => TRUE, 'create' => TRUE),
    ),
   'target_contact_adress' => array(
   'type' => 'entityRef', //I'm guessing I need to change this line to call the address?
   'label' => ts('With Contact Address'),
   'attributes' => array('multiple' => TRUE, 'create' => TRUE),
    ),

Edit: To better explain what I'm trying to do. I'm creating a custom extension for an organization that uses the Activity assignment notification to email their volunteers that don't have access to the CiviCRM database contact information (Phone Numbers and Addresses) about their members. In order to do this I need to add two fields that pull this information when a contact is selected.

Answer 1

I'd suggest you create 2 custom fields for this in the activity (pickup location & contact phone number). You can then use a bit of javascript to insert the contact's email & phone into those fields and it will come through in the activity email. As an added bonus, this approach gives the flexibility of allowing the user to override those defaults if the person needs to be picked up elsewhere.

To do this, your buildform hook needs to do 2 things:

1. Request the extra address/phone info from the target_contact_id field. You can do:

   $form->_fields['target_contact_id']['attributes']['api']['extra'] = array(
     'street_address',
     'city',
     'state_province',
     'postal_code',
     'phone',
   );
   

2. Add your javascript to the form using CRM_Core_Resources (hint: create a js file in your extension, and use CRM_Core_Resources::singleton()->addScriptFile('myExtension', 'js/myScript.js'))

Your javascript can then use some basic jQuery like:

CRM.$(function($) {
  $('#target_contact_id').change(function() {
    if ($(this).val()) {
      // This contains the extra fields you requested
      var data = $(this).select2('data')[0].extra;
      // For example, populate a custom field with the phone
      $('#custom_42').val(data.phone);
    }
  });
});
