Post installation

My goal is to show Tags that got auto generated to the Card View Mode.

I already have the website built by someone and I am trying to learn and play around with it with my requirement.

I have this 

>> Structure --> Taxonomy --> Vocabulary --> Tags and under tag, I have many term

>> Structure --> Display Modes --> Card

>> Structure --> Views -->Products  ( This uses the View Mode as "Card")

>> Structure --> Content types --> Product

This is what I am doing

I'm looking for a reliable, searchable resource focused on Drupal 9/10.  I find that Google is next to useless.  Everything I search for comes up with Drupal 7 mixed in and I waste valuable time checking each link to see if it is relevant.  Today, for instance, I was just searching to find out how to programmatically create a node and add a file field.  Even though I included Drupal 10 in quotes, half the links came up Drupal 7.  The other half were about something that wasn't what I meant at all.  This forum  undoubtedly has some useful information in it.  But I don't see any way to search

I have installed Drupal 10.2.5 twice, via composer. The first time within hours the site threw the PDO error listed below. I re-installed, thinking I must have done something wrong. The site then functioned correctly for a few days, and then the error re-appeared. I cannot find anything in the support forums that covers this. The error is:

Something I used to do routinely back in the good old days of Drupal was to use drupal_set_message to show the contents of an array/object or other structure at key points so that I'd know how to reference certain values within that structure.  I'd use drupal_set_message("<pre>".print_r($node,true)."</pre>") and I'd know the structure.  Now, of course, that is apparently a taboo or something so we must do things according to the "new world order".  So, without telling me about some separate debugger that you use or something else that I'll have to figure out how to use, can some

Hi,

Should we expect to see captions at all in views-based blocks or pages with image fields, or is this feature omitted in 5.x versions?

It seems impossible to display captions in any views-based block or page containing an image field (media: image).

I need to implement one of the following options, if possible:
A) Make the BUY button only send an email or...
B) When processing the cart items, only an email to be sent about the purchased items.

I don't need a real credit card purchase on the site, once we get the email we can process the items manually.
This is for an organization that don't sell items but gives them away.

Any suggestion would be appreciated.
