function drupal_get_token

Generates a token based on $value, the user session, and the private key.

Parameters

$value: An additional value to base the token on.

The generated token is based on the session ID of the current user. Normally, anonymous users do not have a session, so the generated token will be different on every page request. To generate a token for users without a session, manually start a session prior to calling this function.

Return value

string A 43-character URL-safe token for validation, based on the user session ID, the hash salt provided from drupal_get_hash_salt(), and the 'drupal_private_key' configuration variable.
