Quick Tip: Adding a Reset button to a Drupal form
Using hook_form_alter or hook_form_FORM_ID_alter one can easily add a “Reset” button to a Drupal form.
In this example we’re actually trying to reset anything the user typed after the form loaded. This will not remove the default values.
Here’s a simple example (Drupal 6)
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
/** * Implementation of hook_form_alter(). */ function mymodule_form_alter(&$form, &$form_state, $form_id) { switch ($form_id) { case 'myform': $form['buttons']['reset_button'] = array( '#type' => 'markup', '#value' => '<input class="form-button" type="reset" value="Reset">', '#weight' => 2000, ); break; } } |
It may not be appropriate for you to put your new reset element into the buttons array. Use dpm() (part of the Devel module) to show what $form looks like. If you don’t understand this, and the code above isn’t working for you, you may try $form[‘reset_button’] = array….
Adjust the value of #weight to move the button around the form. dpm($form) will show you weights (if any) of existing elements so you can make educated decisions about the weight of your new field.
One last note about the ‘#type’ => ‘markup’ line: this is not a requirement, but I like to include it for clarity.
UPDATE:
Here’s what the field might look like for Drupal 7:

1 2 3 4 |
$form['reset'] = array( '#type' => 'markup', '#markup' => '<input class="form-submit" type="reset" value="Reset">', ); |
