Hello I have created a module to display a block. I would like to set the block visibity to visible and hidden in the homepage based on a condition.

like this:


//fetch status from database then check condition
if ($status = 1){
//make block visible
//hide block

I have searched all over the internet and could not find how to make it work.

I have a form that is used to add contents to a database and it has a checkbox to whether make the make the block visible or not.

So I would fetch the status(visible/hidden) of the block from the database and then make the block visible.

  • Why not create a new visibility context instead of this?

  • We need more information about the condition in order to give you the best solution as in Drupal, you can do this multiple ways: in the block configuration, hooks and/or twig templates Nov 24 at 11:37

When you create a module to display a block this usually means you implement a block plugin. Then you can add the condition to the plugin directly:

  protected function blockAccess(AccountInterface $account) {
    $access = $this->languageManager->isMultilingual() ? AccessResult::allowed() : AccessResult::forbidden();
    return $access->addCacheTags(['config:configurable_language_list']);

Example from core LanguageBlock::blockAccess().

  • Thanks this worked
