I have to form datelist field. If user select incorrect date, for example 1970-02-31, displayed exception Exception:

The array contains invalid values. in Drupal\Component\Datetime\DateTimePlus::createFromArray() (line 149 of core/lib/Drupal/Component/Datetime/DateTimePlus.php).

backtrace:

  1. Drupal\Component\Datetime\DateTimePlus::createFromArray() called at [/var/www/drupal8/core/modules/datetime/datetime.module:802]
  2. form_type_datelist_value() 2 call_user_func_array() called at [/var/www/drupal8/core/lib/Drupal/Core/Form/FormBuilder.php:1542]
  3. Drupal\Core\Form\FormBuilder->handleInputElement() called at [/var/www/drupal8/core/lib/Drupal/Core/Form/FormBuilder.php:1328]
  4. Drupal\Core\Form\FormBuilder->doBuildForm() called at [/var/www/drupal8/core/lib/Drupal/Core/Form/FormBuilder.php:1390]
  5. Drupal\Core\Form\FormBuilder->doBuildForm() called at [/var/www/drupal8/core/lib/Drupal/Core/Form/FormBuilder.php:1390]

I want override exception to return FALSE, and display to user warning about incorrect date.

How do I it?

  • Can't you just put a try catch statement around the calling code ? – Daniel Wehner May 3 '14 at 10:47

As @Daniel Wehner suggests, this can easily be done by wrapping the calling code in a try - catch block. That's what it is for.
