Module development and code questions

One of the elements of my webform is a dropdown list that has a Jquery function assigned that when changing its value shows a message where the form will be sent depending on the chosen value.
The email value is also assigned to a hidden field that is used in the submission of the form to send the email.
This works correctly when all required values are entered and the form is successfully submitted.

Trying to build a field(or fields) that allows the content person to select one of three scenarios for listing nodes from a specific content type.

1. By default list the latest entries (whatever the limit would be like 3)

2. Pull the latest three entries that are tagged with a specific category. (uses a taxonomy list)

3. Manually add 3 entries

Just looking for ideas on how this could be put together in an easy to use way. Any ideas? 

I am looking for a good Drupal 8 module that provides private messaging functions.  I have tried private messages, which gives an error when you send a message. And I have tried Drupal chat, which doesn't let me view the message inbox.  Does anyone have any suggestions for a good module, or have successfully used either of what I mentioned above?

Hello together, I've got a question about my drupal installation. I changed the password in my MySQL database. After that I changed the password in the settings.php too. But after that my site disappeared and I could not log in. When I changed the password again to the old one the site was back again. Can somebody help me with that problem? I changed my password the same way before and it worked. I don't understand why it's not working now.

Hi!

I've inherited from a Drupal website and so far running it has been ok. Now there are a few things missing and I'm looking into modifying current theme and modules made for the site.

So some of the 'site' information are obtain through variable_get('custom_site_info')['xxxx'] such as logo, url , etc... . I can see the missing information through the GUI but how to I find there variable names? More specifically I am trying to get the alt value from the site settings and I've failed to extract that value.

Thank you.

Frank
