nxc_powercontent: create and update content from code and from REST #

This page is for developers who create or change content from scripts or through REST. nxc_powercontent ("NXC Powercontent", originally by NXC) extends how code creates, updates and removes content:

• download files from external resources when creating or updating objects;
• give HTML for ezxmltext attributes;
• set or change locations (main and additional);
• a built-in debug function, convenient in command line scripts;
• no new version is created when an object is updated.

In the Exponential 6 period it was extended for the REST extension ezprestapi, where it provides the create and delete calls of REST API v2 (1.1.0, October 2024; update is checked, then answers 501). Since ezprestapi 1.2.6 that one extension serves REST API v1 and v2; see REST API v1 and v2.

List content classes in a template: class_list #

Since 1.3.0 (12 July 2026) the content fetch function class_list lists content classes without custom PHP. It filters by group, sorts by name and pages, mirroring the admin class list:

{def $classes = fetch('content', 'class_list', hash('as_object', false(), 'sorts', true()))}
{foreach $classes as $class}
    {$class.name}
{/foreach}

Use it for admin dashboards, custom navigation or API responses.

Admin: Copy selected, Hide and Unhide selected #

The extension overrides the kernel's content/action view with its own modules/content/action.php (the module content of the extension). That copy lacked the handlers for CopyButton and HideButton/UnhideButton, so in the admin3 sub-items More actions menu, Copy selected and Hide/Unhide selected fell through to "Unknown content object action" and failed silently.

Since 1.2.0 (21 June 2026) both handlers exist:

• Copy checks canCreate, collects class, section and node metadata for the browse restrictions, and shows the destination selector.
• Hide/Unhide checks can_hide, skips nodes already in the target state, and goes back to the parent view.

See Subitems "More actions" menu.
