Example of how it is possible to use filter to add a validation.
If you want to ensure that the user select a valid category you can insert the below code in functions.php in your active theme. Please note that Frontier Post will set category equal to the default wordpress category (set in settings/writing), so the below example checks if category is empty or equal to the default category.

The below code will then set post status to draft and issue a warning:



Requires Frontier Post version > 3.4.3
// check if categories are empty or only contains default category - if so set status to draft and issue a warning message
function fp_cat_validation($tmp_post, $tmp_task_new, $_POST )
{
$tmp_cat = array_key_exists('post_category', $tmp_post) ? $tmp_post['post_category'] : array();
if (count($tmp_cat) == 0)
{
$tmp_post['post_status'] = 'draft';
frontier_post_set_msg("Warning: Category is empty, please select category - Status set to draft");

}

if (count($tmp_cat) == 1 && $tmp_cat[0] == get_option("default_category"))
{
$tmp_post['post_status'] = 'draft';
frontier_post_set_msg("Warning: Category is set to: ".get_cat_name(get_option("default_category")).", please select category - Status set to draft");

}
return $tmp_post;
}
add_filter('frontier_post_pre_update', 'fp_cat_validation',10,3);

• Filter: frontier_post_msg_output (Enable manipulation of output message $tmp_msg)
• Action: frontier_post_custom_msg (executes just after add/update messages are output)

function frontier_post_output_msg($tmp_msg_type = "default")
	{
	if ( fp_get_option_bool("fps_show_msg") )
		{
		$tmp_msg = isset($_REQUEST['frontier-post-msg']) ? $_REQUEST['frontier-post-msg'] : '';
		
		//****************************************************************************************************
		// Apply filter before output of message

		$tmp_msg = apply_filters( 'frontier_post_msg_output', $tmp_msg, $tmp_msg_type );
		
		echo '<div class="frontier_post_msg">'.$tmp_msg.'</div>';
		}
	// This way cusom messages can be output	
	do_action('frontier_post_custom_msg', $tmp_msg, $tmp_msg_type );
	
	$_REQUEST['frontier-post-msg'] = null;
