Technical instructions

Test links

If you want to test a single link, or multiple links, simply call:

\Contao\System::getContainer()->get('huh.linkchecker.manager.linkchecker')test('http://www.google.de');
\Contao\System::getContainer()->get('huh.linkchecker.manager.linkchecker')test(array('http://www.google.de', 'http://www.twitter.com'));

Back end widget / field

In back end mode there is a widget available called linkChecker; Provide a valid load_callback within you DataContainer field configuration.

//tl_sample.php 

'linkChecker'       => array(
	'label'         => &$GLOBALS['TL_LANG']['tl_sample']['linkChecker'],
	'inputType'     => 'linkChecker',
	'eval'          => array(
	    'linkCheckerTimeout' => 10,
	),
	'load_callback' => array(
		array('MyClass', 'getLinkCheckerHtml'),
	),
),

You can return html-code with anchor tags, a single link or an array of links within your load_callback. The linkCheckerTimeout eval option configures the timeout in seconds for the backend link check. If omitted or invalid, the default timeout is 10 seconds.

// MyClass

public function getLinkCheckerHtml($varValue, \DataContainer $dc)
{
	return '<a href="http://google.de">Google</a>'
}
