I was needing to add a default value to a text field that disappears when you click on the field.

I did found this question :

How to add default text that clears on focus to a form in Drupal?

However, my knowledge is pretty limited as far as creating hooks so I'm a little lost as to the solution being drawup up here.

Could someone please point me in the right direct?

Cheers!

  • Sorry but we can't write code for you. And we can't write a complete documentation. If you need basics, see how to implement a hook? or Examples for Developers. – Mołot Mar 27 '14 at 10:03
  • Thanks Molot, I should have mentioned that I did look into implementing a hook - but I'm unsure how this fits into achieving my desired effect. ie. How do I then link in the JS file. Cheers (edit: Clive's answers solved it) – dangerranger Mar 27 '14 at 10:10

Since this is 2014 you're probably looking for the placeholder attribute, and not an old-school javascript solution.

Broad strokes: Implement hook_form_alter() and add the attribute there:

function MYMODULE_form_alter(&$form, &$form_state, $form_id) {
  if ($form_id == 'foo') {
    $form['bar']['#attributes']['placeholder'] = t('Baz');
  }
}
