I'm using advanced custom fields plugin for front end post with acf_form() passing $args. This is the form, there is another part in functions.php where we initialize wp_insert_post().
<?php
$args = array(
'post_id' => 'new',
'field_groups' => array(1, 2, 3, 4)
);
acf_form( $args );
?>
</div><!-- #content -->
I have a field group named 'Details'. My question is, how to pass data or field to that arguments ('fields_group' => array()) for displaying the fields? I know this is pretty basic, but i'm stuck.
