How can I add a class to #markup output?

Question

I'm using this code to add a cancel button to my form. The link is generated through #markup:

  $form['actions']['cancel'] = array(
    '#markup' => l(t('Cancel'), $destination),
    '#weight' => 20,
  );

I'd like to add a class, cancel, to the link. I tried adding this line:

'#attributes' => array('class' => array('cancel')),

but the class is not added. I'm guessing because #attributes cannot modify #markup? How can I add the class in this case?

Answer 1

You can do this...

$form['actions']['cancel'] = array(
    '#markup' => l(t('Cancel'), $destination, array('attributes' => array('class' => array('cancel')))),
    '#weight' => 20,
  );

The third argument on the 'link' function is for attributes and such...

l($text, $path, array $options = array())
