action_contexts

Usage

Action contexts work in combination with response_contexts to output additiona formats, such as RSS or JSON.

Typically, you check whether the controller passed in the arguments is one defined by your plugin, then add your context (output format) to the array of values.

Then, response contexts you define direct Omeka to the views you have defined for the output.

Value

array $contexts
Array of the contexts available for a controller’s views.

Arguments

Omeka_Controller_Action controller
The controller that is producing the output.

`Zend_Controller_ActionHelper_ContextSwitch <http://framework.zend.com/manual/1.12/en/zend.controller.actionhelpers.html#zend.controller.actionhelpers.contextswitch> context_switch

Examples

Make an RSS feed of your records available at /my-records/browse?output=rss

class MyRecordController extends Omeka_Controller_AbstractActionController
{
    //nothing to do here, since we don't need to override anything
}

class MyPlugin extends Omeka_Plugin_AbstractPlugin
{
    protected $_filters = array('action_contexts');

    public filterActionContexts($contexts, $args)
    {
        if($args['controller'] instanceof MyRecordController) {
            $contexts['browse'][] = 'rss';
        }
        return $contexts;
    }
}
