Class

AJAXMultiFormTestCase

Tests that Ajax-enabled forms work when multiple instances of the same form are on a page.

Code

function testMultiForm() {

  // HTML IDs for elements within the field are potentially modified with
  // each Ajax submission, but these variables are stable and help target the
  // desired elements.
  $field_name = 'field_ajax_test';
  $field_xpaths = array(
    'page-node-form' => '//form[@id="page-node-form"]//div[contains(@class, "field-name-field-ajax-test")]',
    'page-node-form--2' => '//form[@id="page-node-form--2"]//div[contains(@class, "field-name-field-ajax-test")]',
  );
  $button_name = $field_name . '_add_more';
  $button_value = t('Add another item');
  $button_xpath_suffix = '//input[@name="' . $button_name . '"]';
  $field_items_xpath_suffix = '//input[@type="text"]';

  // Ensure the initial page contains both node forms and the correct number
  // of field items and "add more" button for the multi-valued field within
  // each form.
  $this
    ->drupalGet('form-test/two-instances-of-same-form');

  // page update, ensure the same as above.
