*LinkChecker back end widget*

## 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',
'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`.

```
// MyClass

public function getLinkCheckerHtml($varValue, \DataContainer $dc)
{
return 'Google'
}

```
