Module development and code questions

Hello!

I'm developing a Drupal 10 theme using DXPR Builder with the following setup:

This is not a question, just a place to put some information which I could not find for the love of god anywhere and ChatGPT sent me down a wrong rabbit hole. Hopefully it saves somebody else some time? :-)

$new_datetime = gmdate('c', strtotime('+10 days'));

$date_time_obj = new DrupalDateTime($new_datetime, new \DateTimeZone('Pacific/Apia'));

$entity->set('your_date_field', ['value' => $date_time_obj->format(DateTimeItemInterface::DATETIME_STORAGE_FORMAT), 'timezone' => 'Pacific/Apia']);

Hello,

I need to share sessions table between 2 sites (same domain, eg. .mysite.com). In drupal 7, i have already build this in settings.php.

I have created a new database for this.

On drupal 10/11, this seems different, because we cannot achieve this on the database definition in the settings.php. But maybe that's a mistake.

Thanks for your help.

Hi there,

Could someone please guide me on how to validate forms within an iframe? Specifically, I am working with forms such as:

"entity-browser-browse-files-modal-form"
"entity-browser-browse-files-form"

function hook_form_alter(&$form, &$form_state, $form_id) {
 // Add Custom validation
}

I would appreciate any advice or examples on how to properly handle form validation inside an iframe context.

Thank you in advance for your help!
