#1 Devel.module and dpm() are great!

Thanks for posting this tip Will!

I find that one of the single most useful tools for Drupal development is the dpm() function provided by the Devel module.

If you cannot figure out where that variable is that you need, if you have devel module installed, you can simply add the following to your code:

<?php
  dpm($form_values);
?>

It will output a clickable hierarchy of values defined in the $form_values variable.

If you don't have any idea what variable you are even looking for, then you can try this:

<?php
  dpm(get_defined_vars());
?>
