No, I was talking about your options for calling acf_form(). Yours are wrong.
$options = array(
'post_id' => 'new',
'field_groups' => array(
4
),
'post_title' => true,
'new_post' => array(
'post_type' => 'recette',
'post_status' => 'draft',
),
'updated_message' => __("Recette publiée", 'acf'),
'submit_value' => 'Postez votre recette'
);
acf_form($options);
