Take for example the CKEditor admin page, where at file browser settings you can choose IMCE at file browser type. Then you click Save.

Can you program this? I mean in PHP; because I could also find out which SQL query is done, and use drush sql-query, but that is not what I mean. I want to program it because I have a multisite with about 70 sites.

Thanks,

Eric J.

Yes, use hook_form_FORM_ID_alter()

function MYMODULE_form_FORM_ID_alter(&$form, &$form_state, $form_id) {
  $form['#validate'][] = 'MYMODULE_some_validate_function';
  $form['#submit'][] = 'MYMODULE_some_submit_function';
}

function MYMODULE_some_validate_function($form, &$form_state) {
  if ($form_state['values']['foo'] !== 'bar']) {
    form_set_error('foo', t('Foo must be bar'));
  }
}

function MYMODULE_some_submit_function($form, &$form_state) {
  // Do something.
}

It's not possible to be any more specific than that as 'admin' pages vary in their structure. Most are created using a system_settings_form(), though, so there's a reasonable amount of consistency.

It's also worth noting that a form created with system_settings_form() saves its data in the variables table, so you can accomplish the same thing in a lot of cases with variable_set():

variable_set('site_name', 'New name');

  • Thanks. In my_form_alter I said $form_state["values"]["filebrowser"]="imce". But I do not know how to program what you do on the UI page: click the Save submit button. Think about all the post data, how do I do that? – ericj Jan 6 '14 at 19:29
