How to use the dsm( ) Devel function to print the $form array of my form?

Question

I want to use the dsm() function of the Devel module to print the $form array of a form, where the form_id is search_theme_form. How to do that?

Answer 1

Start a custom module, insert this code:

/**
* Implements hook_form_alter().
*/
function foo_form_alter(&$form, $form_state, $form_id) {
  if ($form_id == 'search_theme_form') {
    dpm($form);
  }
}

Also, you might want to use dpm() over dsm() since the latter is a legacy function.

Answer 2

function THEME_form_search_theme_form_alter (&$form, &$form_state){

krumo ($form); // you can use DSM as well here

}

Replace THEME with your theme name and put that in your template.php, if you want to do that from a module then replace THEME by your module name and put that funciton in your .module file

Answer 3

Use drupal_retrieve_form to get the structured form array:

$form_state = array();
dsm(drupal_retrieve_form('search_theme_form', &$form_state));
