Drupal 8.x

We are currently considering Drupal 8 for a forum/community support site. Whilst there are various forum sites running on Drupal 7 (this one for example) I have been unable to find any high profile/high traffic forum sites running specifically on Drupal 8. If we are unable to find any it is going to be difficult to argue that Drupal 8 is a good platform for our project, so I would greatly appreciate any suggestions or help you can give.

Many thanks. 

Hello, a few weeks ago I encountered the problem of "Drupal is already installed". No suspicious activity was done before that. During my research, I realized that it was due to a bad installation. I redid the installation following the drupal guide. For two days, the problem has reappeared. I admit that I can not find a tangible solution. Indeed, I already have a site on it with the theme TheMag. My concern is to recover my site with the data: return to an initial situation. I am at version 8.7.6
Thank you for your contributions and indications

Hi,

I am trying to get the language id as follows:

$arg = "Sanskrit";

$languages = \Drupal::service('language_manager')->getLanguages();
foreach ($languages as $language) {
if ($arg == $language->getName()) {
$arg = $language->getId();

}
}

print_r($arg);exit;

It should print dv, since the Id for language Sanskrit is dv in my module. But it prints Sanskrit.

Hello Friends,

I have been tasked with adding eccomerce functionality to my Drupal 8 site.

Currently I am looking at the Commerce 2.x module to help me with achieving this. 

The problem I am currently facing is that I am required to store and query all content in a custom database and the Commerce 2.x module looks like it relies heavily on Drupals native database.

Some solutions I am considering are:

In Drupal 7 I did this in my page callback:

function ops_view_pdf() {
	$filepath = $_GET['file'];
	drupal_add_http_header('Cache-Control', 'private');
	drupal_add_http_header('Content-Type', 'application/pdf');
	readfile($filepath);
	return NULL;
}

How do I do this in Drupal 8?

Hey guys,

How can I hide the edit button that shows up in blocks?

I have one showing up on top of the search button of the search block that I don't want it to show.

Thanks.
