5 | * Class TokenRow | |
6 | * @package Civi\Token | |
7 | * | |
8 | * A TokenRow is a helper providing simplified access to the | |
9 | * TokenProcessor. | |
10 | * | |
11 | * A TokenRow combines two elements: | |
12 | * - context: This is backend data provided by the controller. | |
13 | * - tokens: This is frontend data that can be mail-merged. | |
14 | * | |
15 | * The context and tokens can be accessed using either methods | |
16 | * or attributes. The methods are appropriate for updates | |
17 | * (and generally accept a mix of arrays), and the attributes | |
18 | * are appropriate for reads. | |
19 | * | |
20 | * To update the context or the tokens, use the methods. | |
21 | * Note that the methods are fairly flexible about accepting | |
22 | * single values or arrays. If given an array, the values | |
23 | * will be merged recursively. | |
24 | * | |
25 | * @code | |
26 | * $row | |
27 | * ->context('contact_id', 123) | |
28 | * ->context(array('contact_id' => 123)) | |
29 | * ->tokens('profile', array('viewUrl' => 'http://example.com')) | |
30 | * ->tokens('profile', 'viewUrl, 'http://example.com'); | |
31 | * | |
32 | * echo $row->context['contact_id']; | |
33 | * echo $row->tokens['profile']['viewUrl']; | |
34 | * | |
35 | * $row->tokens('profile', array( | |
36 | * 'viewUrl' => 'http://example.com/view/' . urlencode($row->context['contact_id']; | |
37 | * )); | |
38 | * @endcode | |
