Prerequisites

Before diving into the code, make sure you have the following prerequisites in place:

• Drupal 10 installed and configured
• Multilingual support enabled
• At least two languages installed and configured
• A content type with translated nodes

Load a Node

First, we need to load a node in Drupal. We can do this using the load() method of the Node class. Here's an example:

// Load a node with the ID of 1.
$node = \Drupal\node\Entity\Node::load(1);

Get the Translated Node Programmatically

To get the translated node programmatically, you can use the getTranslation() method. You'll need to provide the target language code as an argument:

// Get the translated node in French (assuming the language code is 'fr').
$translated_node = $node->getTranslation('fr');

If you're unsure about the target language code, you can retrieve it from the user's language preference using the following code:

// Get the user's preferred language code.
$language_code = \Drupal::languageManager()->getCurrentLanguage()->getId();

Working Example

Here's a full working example to demonstrate how to get the translated node programmatically in Drupal 10:

// Load a node with the ID of 1.
$node = \Drupal\node\Entity\Node::load(1);

// Get the user's preferred language code.
$language_code = \Drupal::languageManager()->getCurrentLanguage()->getId();

// Check if the node has a translation in the user's preferred language.
if ($node->hasTranslation($language_code)) {
  // Get the translated node.
  $translated_node = $node->getTranslation($language_code);
  // Output the title of the translated node.
  $translated_title = $translated_node->getTitle();
  print $translated_title;
} else {
  // Output a message if no translation is available.
  print "No translation available for the node in the preferred language.";
}
