After Display Page

do_action( 'vikrestaurants_after_display_{$page}', JView $view )

Fires after displaying a page of the plugin.

Description

This hook is triggered every time the plugin completes the rendering of a page.

The dynamic portion of the hook name, $page, refers to the name of the page calling the hook. This means that, for example, the tables page will trigger an hook called vikrestaurants_after_display_tables.

DO NOT echo any HTML in this hook to avoid sending the headers in advance.

Parameters

$page

(JView)  The page instance.

Example

The example below explains how to extend the toolbar with a custom button within the take-away orders list.

/**
 * Fires after the controller displayed the page.
 *
 * @param  JView  $page  The page instance.
 */
add_action('vikrestaurants_after_display_tkreservations', function($page)
{
    // adds a button to archive the take-away orders
    JToolbarHelper::archiveList('tkreservation.archive');
});

Every time the archive button is clicked, the plugin will submit the request to the following end-point.

/wp-admin/admin.php?page=vikrestaurants&task=tkreservation.archive

It is now possible to rely on the vikrestaurants_before_dispatch hook to intercept the request and archive the selected reservations.

add_action('vikrestaurants_before_dispatch', function()
{
    // get requested action
    $task = isset($_REQUEST['task']) ? $_REQUEST['task'] : '';

    if (is_admin() && $task == 'tkreservation.archive')
    {
        // get selected records
        $ids = isset($_REQUEST['cid']) ? (array) $_REQUEST['cid'] : array();

        if (count($ids))
        {
            /**
             * @todo archive selected orders
             */
        }

        // then go back to the orders list
        wp_redirect('admin.php?page=vikrestaurants&view=tkreservations');
    }
});
