Display Table Body

apply_filters( 'vikrestaurants_display_{$page}_table_td', mixed $body, array $rows, JView $view, array $config )

Fires while displaying the table body of a specific entity.

Description

This hook is triggered within the list pages of certain sections of the plugin. It is possible to use this hook to include additional columns within list tables.

DO NOT include td tags because they are automatically added by the system. Lean on data-id attribute for individual styling.

Each value of the resulting array must declare an array containing the HTML for each column within the list.

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

IMPORTANT NOTE: not all the pages trigger this hook. Before to start coding a plugin, you should make sure that the page supports that hook, by checking whether the onDisplayTableColumns() method is used. This can be done by accessing the page at the path:

/wp-content/plugins/vikrestaurants/admin/views/{$page}/tmpl/default.php
(back-end pages)

Parameters

$body

(array|null)  An associative array containing the new columns to include. The key of the array should be a unique identifier to correctly pair the body with the head. The value of the array should be an array containing all the values to display (one per row).

At the first hook execution, the argument may be a null value.

$rows

(array)  An array of fetched records.

$page

(JView)  The page instance holding the record details.

$config

(array)  An associative array of options.

Example

The example below displays the stay time of the reservations under the related list.
