Gravity_form_enqueue_scripts

Greetings,

I'm totaly new to gravity form, I'm currently playing with a simple one line form (newsletter subscribtion) while reading the documentation to try to understand how it works.

I'm mostly trying to style it and see the different behaviors, so far so good

I'm inserting the form directly in my template

I have a couple of questions

so that I use the documentation on
http://www.gravityhelp.com/documentation/page/Gravity_form_enqueue_scripts
it is said that the enqueue has to be added to the header...
1° is it possible to add it from my template page using a hook? so that the gravityforms/css/forms.css?ver=1.6.1 is only added to needed page
what about if I put it onto the functions.php with an if statement to pust it only for a given page?

2° assuming that I want to fully style from my templace style.css, is there a way to avoid the gravity form own css to be displayed? I understand from some post in this forum that it is a configuration on the admin panel, but just can't find it

thank you very much in advance

Thank you for your help.

shall I fire the wp_head or init hook?

I have written something like

function gr_gravity_form_enqueue_scripts()
{
	if ( is_page(4))
	{
	gravity_form_enqueue_scripts(1, true);
	}
}
add_action('wp_head', 'gr_gravity_form_enqueue_scripts');

is that the correct way?

@Chris Hajer

Thank you very much for your replied

yes using the head worked, since I'm new to Gravity Form, I was just trying to make sure I was doing the right way.

it is the very same with WP, there is so many 'roads' that lead to the goal, but some are good use of WP logic while other are just twisted ways.. since I try to learn the best practise as much as possible, hence my question

playing a bit more with the gravity form, I'm wondering if I'm not going to do a function based on page and fire each needed hook/filter for gravity form from this function

doing something like below, would that be a smart way to code?

add_action('wp_head', 'gr_gravity_form_init');

function gr_gravity_form_init()
{
	if ( is_page(4)) //
	{
	gravity_form_enqueue_scripts(1, true);
	add_filter("gform_validation_message_1", "gr_gravity_form_nl_wrong_email", 10, 2);
	}
}

function gr_gravity_form_nl_wrong_email($message){
  return "<span class=\"validation_error\">Oups, there's an error - please fill with a valid email !</span>" ;
}

Thank you in advance
