TemplateTag::subscripting

$tag[$key]

Up: class TemplateTag

The class TemplateTag implements the methods of the interface ArrayAccess so that subscripts are used to reference string values which correspond either to values of the attribute 'data-key' or to the position of a child tag under the current tag.

parameter	description
$key	a string which is used to search the children of this tag for a match on either the data-key attribute or the position under this tag

For example the shared translate template 'TranTabfr.html', which encapsulates translations to French, includes the following tables, among others:

    <div id="LMonths">
      <span></span>
      <span>Janvier</span>
      <span>Fevrier</span>
      <span>Mars</span>
      <span>Avril</span>
      <span>Mai</span>
      <span>Juin</span>
      <span>Juillet</span>
      <span>Août</span>
      <span>Septembre</span>
      <span>Octobre</span>
      <span>Novembre</span>
      <span>Decembre</span>
    </div>
    <!-- general I18N translate table -->
    <div id="tranTab" class="hidden">
      <span data-key=""></span>
      <span data-key="a[fem]">une</span>
      <span data-key="a[masc]">un</span>
      <span data-key="about">environ</span>
      <span data-key="AD">ap. J.-C.</span>
      <span data-key="adopted">adopté</span>
 ...
    </div>

Given that $template is an instance of class FtTemplate which includes internationalization support:

    $translate          = $template->getTranslate(); // gets `'TranTab$lang.html'` as instance of Template
    $lmonths            = $translate['LMonths'];     // get a translation table
    $april              = $lmonths[4];               // is 'Avril'
    $t                  = $translate['tranTab'];     // get a translation table
    $after              = $t['after'];               // is 'apres'
    $t['never']         = 'jamais';                  // you may update the table locally
