I am trying to make a shortcode for Visual Composer. I have to get all the custom post types as dropdown. I am using the get_post_types() function, but it returns an empty array.

Here is my code: 

 /*Post type shortcode*/
 add_action( 'vc_before_init', 'post_type_shortcode');
function post_type_shortcode(){
$args = array( 'public' => true, '_builtin' => false );
$output = 'names'; //'names'; // names or objects, note names is the default
$operator = 'and'; // 'and' or 'or'
$custom_post_types = get_post_types( $args, $output, $operator );
vc_map( array(
    "name" => __( "Display Post Type", "saue" ),
    "description" => "Display post type",
    "base" => "display_post_type",
    "class" => "",
    "category" => __( "Saue Theme", "saue"),
    "params" => array(
        array(
            "type"          => "dropdown",
                    //"holder"        => "div",
            "heading"       => __( "Post Type", "saue" ),
            "admin_label" => true,
            "param_name"    => "post_type",
            "value"         => $custom_post_types,
            ),
        )
    ) );

}

I have also tried to get it in the functions.php but result is same.

I also used add_action('init',"function_name');, it works within the hook but not outside of the hook.

Can any one help me please?

It works with when executing on the init action? - Ty Bailey
It works fine. add_action('init','getPostTypes'); function getPostTypes() { $post_types = get_post_types(); var_export($post_types); } but if use return $post_types it returns only default post types. - Fencer Monir

Try with admin_init hook, which runs after init:

/*Post type shortcode*/
add_action( 'admin_init', 'post_type_shortcode');
function post_type_shortcode(){
$args = array( 'public' => true, '_builtin' => false );
$output = 'names'; //'names'; // names or objects, note names is the default
$operator = 'and'; // 'and' or 'or'
$custom_post_types = get_post_types( $args, $output, $operator );
vc_map( array(
    "name" => __( "Display Post Type", "saue" ),
    "description" => "Display post type",
    "base" => "display_post_type",
    "class" => "",
    "category" => __( "Saue Theme", "saue"),
    "params" => array(
        array(
            "type"          => "dropdown",
                    //"holder"        => "div",
            "heading"       => __( "Post Type", "saue" ),
            "admin_label" => true,
            "param_name"    => "post_type",
            "value"         => $custom_post_types,
            ),
        )
    ) );

}

I have modified your code around the line where you are calling $custom_post_types for your shortcode values.

/*Post type shortcode*/
add_action( 'vc_before_init', 'post_type_shortcode');
function post_type_shortcode(){
$args = array( 'public' => true, '_builtin' => false );
$output = 'names'; //'names'; // names or objects, note names is the default
$operator = 'and'; // 'and' or 'or'
$custom_post_types = get_post_types( $args, $output, $operator );
vc_map( array(
    "name" => __( "Display Post Type", "saue" ),
    "description" => "Display post type",
    "base" => "display_post_type",
    "class" => "",
    "category" => __( "Saue Theme", "saue"),
    "params" => array(
        array(
            "type"          => "dropdown",
            //"holder"      => "div",
            "heading"       => __( "Post Type", "saue" ),
            "admin_label"   => true,
            "param_name"    => "post_type",
            "value"         => $custom_post_types->name,//see this line
            ),
        )
    ) );
}

This line should return the names of the post types registered. Hope this works for you!
