Drupal. How to display a field from file_managed table?

Question

PHP

Guys, hello everyone. Tell me please. In the file_managed Drupala table, I introduced a new field - hash. Varchar. After that I want to display the value of this field in $content. In block.module, I found the template_preprocess_block function, which gives content with additional fields as links for downloading files attached to the content. Var_dump dumps all the fields of the file_managed table, but without my last hash field. I hope the question is clear .. you need to display the value of the hash field

Answer 1

It was necessary to use the File Entity module, which allows you to connect fields to the File, then you could show / change anywhere through the UI.
Now you will have to pull out the hash through the code (since $content - you want to show it in the node):

// Узнаем fid
  $fid = $node->field_image[$node->language][0]['fid']; 
   // Получаем hash
  $hash = db_query("SELECT hash FROM {file_managed} WHERE fid = :fid", array(':fid' => $fid))->fetchField();
