Yes, you can output an entire tab using the below API.
Code:
$tabContents = $cbUser->getTab( TAB_ID_HERE );
The variables for this function are as follows (with phpdoc).
Code:
/**
* Gets the rendered $tab
*
* @param int $tab Tab id to render
* @param string $defaultValue Default HTML to render if the tab does not render
* @param string $output [optional default='html'] Output format
* @param string $formatting [optional] Formatting
* @param string $reason View of tab (default: 'profile')
* @return string|null HTML or null if $position does not exist
*/
public function getTab( $tab, $defaultValue = null, $output = 'html', $formatting = null, $reason = 'profile' )
I'll update the below tutorial with more up to date getFields usage and include the tabs usage.
