wordpress get taxonomy list of custom post type

Question

I am using "Video" theme for my wordpress website. In this theme, videos post type and "videoscategory" taxonomy are defined. Here is the register code for taxonomy:

add_action("init", "custom_posttype_menu_wp_admin1");
function custom_posttype_menu_wp_admin1()
{

 register_post_type('videos', 
            array('label' => __('Videos','templatic'),
                    'labels' => array(  'name' => __('Video','templatic'),
                                'singular_name' => __('Video','templatic'),
                                'add_new' => __('Add Video','templatic'),

$tax_terms =get_terms('videoscategory');

but get empty array. Does anyone know what is the problem? thanks.

Here is use this code, you definitely find your solution

$cat_args = array(
    'orderby'       => 'term_id', 
    'order'         => 'ASC',
    'hide_empty'    => true, 
);

$terms = get_terms('videoscategory', $cat_args);

    foreach($terms as $taxonomy){
         $term_slug = $taxonomy->slug;

    $tax_post_args = array(
          'post_type' => 'videos',
          'posts_per_page' => 999,
          'order' => 'ASC',
          'tax_query' => array(
                array(
                     'taxonomy' => 'videoscategory',
                     'field' => 'slug',
                     'terms' => '$term_slug'
                )
           )
    );

    $tax_post_qry = new WP_Query($tax_post_args);

    if($tax_post_qry->have_posts()) :
         while($tax_post_qry->have_posts()) :
                $tax_post_qry->the_post();

                the_title();

          endwhile;

    else :
          echo "No posts";
    endif;
} //end foreach loop

There is an example in the codex when you visit the get_terms page

$terms = get_terms('videoscategory');
 if ( !empty( $terms ) && !is_wp_error( $terms ) ){
     echo "<ul>";
     foreach ( $terms as $term ) {
       echo "<li>" . $term->name . "</li>";

     }
     echo "</ul>";
 }

Just a tip: objects created under a custom taxonomy is called terms, not categories. Please see this post I've done on WPSE

Here's an example for you that I used for a FAQ post type:

get_header();
if(have_posts()) {
    $args = array (
        'orderby'    => 'name',
        'order'      => 'ASC',
        'hide_empty' => true,
    );
    $terms = get_terms( 'faq_levels', $args );
    foreach ( $terms as $term ) {
        echo $term->slug;

        $post_args = array (
            'post_type'  => 'faq',
            'faq_levels' => $term->name,
        );
        $query = new WP_Query( $post_args );
        while ( $query->have_posts() ) {
            $query->the_post(); ?>

and I created the post type like this:

function post_type_faqs() {
    register_post_type('faq', array(
        'label'=>'FAQ',
        'menu_icon' => '',
        'labels'=>array(
            'name'=>_x('FAQs', 'post type general name'),
            'singular_name'=>_x('FAQ', 'post type singular name'),
            'add_new'=>_x('Add New', 'faq'),
            'add_new_item'=>__('Add New FAQ'),
            'edit_item'=>__('Edit FAQ'),
            'new_item'=>__('New FAQ'),
            'view_item'=>__('View FAQ'),
            'search_items'=>__('Search FAQs'),
            'not_found'=>__('No faqs found'),
            'not_found_in_trash'=>__('No faqs found in Trash'),
            'parent_item_colon'=>''),
        'public'=>true,
        'publicly_queryable'=>true,
        'show_ui'=>true,
        'query_var'=>true,
        'rewrite'=>false,
        'capability_type'=>'post',
        'supports'=>array('title','thumbnail','post-formats'),
        'taxonomies'=>array('post_tag','faq_category'),
        'slug'=>'faq',
        'hierarchical'=>false,
        'menu_position'=>6,
        'show_in_nav_menus'=> true,
        'has_archive' => true,
        'can_export' => true,
        'register_meta_box_cb' => 'faq_add_meta_boxes'

    ));
}
add_action('init', 'post_type_faqs');
