Question

I’ve created a custom module with it’s own settings page where the administrator can set certain parameters (radio buttons, input fields and dropdown).

I’m looking for a way to create a button in the form that will perform a custom function.
(Example: Like the ‘clear all caches’ button in the admin page.)

What’s the easiest or best way to create this?

Kind regards and thanks in advance!

Each different button on your form can perform a different function by assigning it the #submit property:

function mymodule_my_form($form, &$form_state) {
  $form['button1'] = array(
    '#type' => 'submit',
    '#value' => 'Perform 1st Action',
    '#submit' => array('mymodule_my_form_action_one')
  );

  $form['button2'] = array(
    '#type' => 'submit',
    '#value' => 'Perform 2nd Action',
    '#submit' => array('mymodule_my_form_action_two')
  );
}

function mymodule_my_form_action_one($form, &$form_state) {
  // Perform the 1st action
}


function mymodule_my_form_action_two($form, &$form_state) {
  // Perform the 2nd action
}

Only the specified submit function will run for each button click.
