How to set taxonomy in custom plugin? - wordpress

Question

I am trying to create a plugin, I need a custom post and taxonomy. But it can be accessible in admin side, but the taxonomy is not working on front-end.
This is how I registered the custom post and taxonomy:
function post_type_questionnaire()
{
$labels = array(
'name' => _x('Questionnaire', 'post type general name'),
'singular_name' => _x('Questionnaire', 'post type singular name'),
'add_new' => _x('Add New Question', 'questionnaire'),
'add_new_item' => __('Add New Questionnaire')
);
$args = array(
'labels' => $labels,
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'query_var' => true,
'rewrite' => true,
'_builtin' => false, // It's a custom post type, not built in!
'capability_type' => 'post',
'hierarchical' => false,
'menu_position' => null,
'supports' => array('title',
//'editor',
/*'excerpt',
'thumbnail',
'trackbacks',
'custom-fields',
'comments',
'revisions',
'author',
'page-attributes'*/
));
register_post_type('questionnaire',$args);
}
add_action('init', 'post_type_questionnaire');
function create_questionnaire_taxanomies(){
register_taxonomy('qcategories','questionnaire', array(
'hierarchical'=>true,
'label'=>'Questionnaire Categories',
'rewrite' => array( 'slug' => 'questionnaire' )
));
}
add_action('init', 'create_questionnaire_taxanomies',0);
I am using a shortcode to display it in front-end.
by using the code below it shows all posts
$args = array(
'post_type' => 'questionnaire',
'posts_per_page' => -1,
);
$query = new WP_Query($args);
if ( $query->have_posts() ) { ?>
<?php while ( $query->have_posts() ) :query->the_post(); ?>
But when I try to specify a taxonomy term it doesn't work and this is the code:
$args = array(
'post_type' => 'questionnaire',
'posts_per_page' => -1,
'tax_query' => array(
array(
'taxonomy' => 'qcategories',
'field' => 'slug',
'terms' => $atts["name"]
)
)
);
$query = new WP_Query($args);
if ( $query->have_posts() ) { ?>
<?php while ( $query->have_posts() ) : $query->the_post(); ?>
When I tried to display the count of post in a template page it show nothing:
$term = get_term( 3, 'qcategories' );
echo $term->count;
This outputs nothing, so I believe that the taxonomy is not registering, can anybody help me to register the taxonomy in my custom plugin. Thanks in advance!
Edited
This is the output of $args:
array (size=3)
'post_type' => string 'questionnaire' (length=13)
'posts_per_page' => int -1
'tax_query' =>
array (size=1)
0 =>
array (size=3)
'taxonomy' => string 'qcategories' (length=11)
'field' => string 'slug' (length=4)
'terms' => string 'new' (length=3)

Looked like the code was just fine, as OP discovered there was just a little oversight in the code i.e in the plugin before registering taxonomy there was WordPress template tag if(is_admin()) which resulted the code work just fine in the Admin Panel, however when it was called in the front-end , there was no Taxonomy available for the WP_QUERY
Removing that admin_only if condition, code will just work fine.
