mysite.module, line 1940

Description

Given values, generate a table that behaves like a form so that users my add content to their MySite page.

Parameters

$owner The $user object for the owner of this MySite page.

$edit The values passes from mysite_content_form(). Originally, this was going to be a form, but it was easier to make it links to menu callbacks.

$label The name of the content type as defined by the mysite_type() array.

$options The content options available to be added to a MySite page.

$style The layout to use for the form. Values are 'table' and 'grid.'

$page The current page of the mysite collection.

Return value

A Drupal-themed table of content choices, with action links.
