Module development and code questions

Can someone tell me what the icons and buttons were made with on this site ..

Home | Front Range Fire Rescue (colorado.gov)

I have adapted the embed code to my site...

Home | Town of Dinosaur (colorado.gov)

I would like to know an easier way to do this.  I am only a programmer for the site and don't have access anything except my landing pages.

Thanks..  Jim

I am unable to locate the Drupal 9 API page for dpr(). Here is a link to the
Drupal 8 API for this function.

What is the Drupal 9 replacement for this?

A function with that name exists for Drupal 9, as $nodedump = dpr($nodes, TRUE, 'mymodule'); does not trigger an error.

However, it doesn't work. $nodedump is always empty.

Hi,

Is there a way I can add new nodes and update existing ones (if I have the uuid or nid) from an external process (php/python) that would run on the same server as Drupal.

Is there any API Drupal exposes that can be used for that?

Can I program a module that would be used as such API?

Another option is to store the new and updated nodes' data in a DB and write a module that reads and updates Drupal nodes, but I don't know how to make this module run every N minutes without user interaction? (can it be done with cron?)

* latest Drupal 9.x *

So I got this multi-cardinality field of type `text_long` which always contains 3 entries. Let's call them field_1, field_2 and field_3.

After saving the containing node, all the empty fields are getting stripped from the saved entity when they are empty, this is not what I want.

So whenever someone saves a value into one of the latter fields (let's say field_3) because the field_1 and field_2 are empty, the first 2 will not be saved and on subsequent node edits the values I put into field_3 are being shown in field_1.

What I've tried so far:

hello everyone,

why my Drupal 7 will be show up this error URL (markltup! Universal markup editor)?

any solution? how to fix it?

Thanks in advance

Hi,

I'm writing a standalone php code(not a module) that uses Drupal API 9.2.6

If I try to load a node (either by nid or uuid) it loads fine but when I try to save it back it fails (even without any changes)
$em = $kernel->getContainer()->get('entity_type.manager');
$mynode = $em->getStorage('node')->load(69); // WORKS FINE AND LOADS THE NODE DATA
// do nothing
$mynode->save();  // FAILS
