Module development and code questions

Hello, I have two fields in a form that alternate as I select a third. This function is made with #dependency of ctools. I am trying to do a validation with #ajax so that the page is not read every time it is pressed. The user presses submit but on the screen that returns #ajax the functionality of #dependency of ctools is lost and the two fields can be seen at the same time. I have already tried many things but I am stuck, if someone has had the same problem I would appreciate the help. This is the code of the three fields.

Hello Friends,

I have a contact form located in ContactForm.php that sends a email using the plugin.mail.manager

$temporary = Drupal::entityQuery('group_content')->condition('id', $id)->execute();

This is returning the ‘id’ column in my table. I want a different column, entity_id. What should I call to return a different column rather than only returning the id column in the table.

Hi,

It's possible to show the description of field file in field.html.twig ?

Now, i have only url of file and label.

Thank you

Anthony
