1 file.api.php hook_file_operations()

Add mass file operations.

This hook enables modules to inject custom operations into the mass operations dropdown found at admin/content/file, by associating a callback function with the operation, which is called when the form is submitted. The callback function receives one initial argument, which is an array of the checked files.

Return value

array: An array of operations. Each operation is an associative array that may contain the following key-value pairs:

  • 'label': Required. The label for the operation, displayed in the dropdown menu.
  • 'callback': Required. The function to call for the operation.
  • 'callback arguments': Optional. An array of additional arguments to pass to the callback function.
