Sorry for bother,

I just can't understand why my plugin isn't working, the post type screen is ok, but the shortcode action does'nt work at all.

When adding [mensagem], it supposed to add the form into the page, but anything show up when doing so :(

    require_once 'creation.php';

    add_action( 'init', 'msg_custom_init',2 );
    add_action( 'admin_print_styles', 'action_admin_print_styles', 3 );
    add_filter( 'manage_' . 'msg' . '_posts_columns', 'filter_manage_msg_posts_columns',4 );
    add_action( 'manage_posts_custom_column',  'action_manage_posts_custom_columna' , 5, 2 );

    add_shortcode( 'mensagem', 'mensagem_shortcode',6 );
    add_filter('get_header','wp_sd',7);
    add_filter('get_header','mensagem_form',8);

//cria shortcode
function mensagem_shortcode() {
    do_action('wp_head','mensagem_form');
    include('form.php');
  }

function mensagem_form() {
    include('form-action.php');
  }

//imprime estilos
function wp_sd($result) {
 wp_enqueue_style('extra_st', WP_PLUGIN_URL . "/simple-messages/style.css");

}

?>

Shortcodes are never, ever, supposed to produce output. They're
supposed to *return* output.

A shortcode is, basically, a filter.

Give this a quick read:

Also, that isn't how do_action works. Not sure what you're trying to
do there, actually.

Thanks Otto,

I'm using the do_action to put content on header when using the shortcode, I
don't really know how could I put scripts, css and else only when the
shortcode is being used only. Is there someway?

The shortcode isn't processed until the header has already finished
and you're displaying the content later on the page. Better to enqueue
scripts and such into the footer if you have to do it that way.

However, I was really referring more to your includes and lack of a
"return" on the shortcode. That's your main problem.
