  How are you currently outputting the form on the page? e.g: <?=form('contact')?>
  The forms.php config file has a default 'email_subject' line and 'email_from' parameter that is for all forms, however, you can specify it at the form level as well:
  <?=form('contact', array('email_subject' => 'My subject line...'))?>

  Thanks that good to know. I am using <?=form('contact')?> but what I would like to do is have the emails subject line contain the name of the name field. Will I be able to do that using a hook?

  You can use the "post_process" hook. The first parameter passed to your hook will be an instance of the form object itself in which you can set the property.

  I couldn't get the hook to work. May be if you have time you could explain in more detail.
  However I altered the function in Fuel_Forms.php to
  
  protected function get_email_subject() { if (empty($this->email_subject)) { return $this->fuel->forms->config('email_subject'); } $email_subject = str_replace(array('{{', '}}'), array('{', '}'), $this->email_subject); $output = parse_template_syntax($email_subject, $_POST, TRUE); return $output; //return $this->email_subject; }
  
  This allows me to add a email subject line via the CMS for that form with {{name}} template tag so that it's parsed with the $_POST['name'] value
  
  It's a hack to the core forms code and Im sure theres a better way to do this...

  To use a hook, you can do the following:
  
  1. Create a hook function and place it your fuel/application/helpers/my_helper.php like so:
  function my_form_post_process($form) { $form->email_subject = 'This is a TEST!!!'; }
  2. Then in your fuel/application/config/forms.php, add the following to your $config['forms']['forms']['my_form'] where my_form is the name of your form:
  $config['forms']['forms'] = array( 'my_form' => array( // ..... additional config stuff goes here 'hooks' => array('post_process' => 'my_form_post_process'), ) );

  Thanks but still not calling the my_form_post_process function.
  
  i set it up as you have above but changed the my_form to contact
  
  It looks like that the hook added to the config>forms.php file is not been added to $hooks on the form object.
  
  I added it manually into
  protected $hooks = array('post_process' => 'my_form_post_process');
  in the Fuel_forms.php file and your example above works and changes the email subject to: This is a TEST!!!
  
  Any further help would be appreciated.

  Hmm... if you debug fuel/modules/forms/Fuel_forms.php around line 747 does it have the name of the function? I tested the method above and it seemed to work OK for me.
  $this->call_hook('post_process');
