currently I'm using two hooks in my hook.module. hook_form_alter() and hook_mail_alter().
In hook_form_alter() I use drupal_get_messages() to retrieve the status message.
And I want to use hook_mail_alter() to add this message to the email. But I can't pass the message content from one hook to the other.
A global variable is not working. Is there a better way? Another hook I'm not aware of?
I suppose you have tried to use drupal_get_messages() within hook_mail_alter() as well?
The reason it probably did not return a value is because the default behavior or drupal_get_messages() is to clear the message queue (so it empty the second time). You can however make it persistent by passing FALSE as a second parameter (see the documentation).
So in your hook_form_alter() use drupal_get_messages(NULL, FALSE) and then you should be able to use it again in hook_mail_alter().
drupal_set_message() and that pulls them from $_SESSION['messages']. As long as you do not reset the queue it should be available in every function. (Assuming you do not use iframe to other sites, then there is nothing you can do) .
