Module development and code questions

Hello all,

I am trying to patch a submodule: jsonapi_defaults installed with jsonapi_extras (modules/jsonapi_extras/jsonapi_defaults) using composer on Drupal 8.9.10.

I tried the following:

    "extra": {
         "patches": {
        "drupal/jsonapi_extras" : {
        "Configurable JSON:API Max Limit": "https://www.drupal.org/files/issues/2020-08-09/max-page-limit-configurable_2884292_17.patch"
         }
        },

But was not able to apply patch to the submodule.

Thanks in advance.

Hello,

In my custom form I'am trying to get values from a nested taxonomy checkboxes field.

$form['test'] = [
'#type' => 'checkboxes',
'#title' => t('title'),
0 => array(
'#type' => 'checkboxes',
'#options' => array('1' => 'one'),
0 => array(
'#type' => 'checkboxes',
'#options' => array('2' => 'two'),
),
),
1 => array('#type' => 'checkboxes',
'#options' => array('3' => 'three'),
),
];

Hello iam using ajax in my drupal forms and i need to apply a test on my event witch is a user triggered or code triggered!
So, drupal forms provide an event key:
[#ajax] => array(
'event' => 'change',
... )
I need something like this to know about the event origin:

If(e.originalEvent) {

// user triggered

} else {

// code triggered

}

My purpose is to test my event and knowing that change event caused by code triggered (jquery replace html by ajax) or user triggered.

Since I can't find a solution, maybe someone can give a hint?

I have a form of a certain content-type where users can enter data and upload images (type: Media Library -> image, entity referencing). In addition, I have a Boolean field (uploaded images: yes / no) that I would like to use elsewhere.

(How) Is it possible that the Boolean field (BF) is automatically checked as soon as the user uploads an image?

I've tried different things:

What are the new features that added in Drupal 9?
