Check if current page has given tag ID

I am using custom taxonomies.

How to check if current page has tag_ID = "XXX" ?

If that is any help the URL form WordPress admin looks like this:

http://localhost/website/wp-admin/edit-tags.php?action=edit&taxonomy=company&ta‌g_ID=13&post_type=news 

Update. Here is code which I’m currently using. Does not work.

<?php
function insert_news($company = 0)
{
    global $post;

    $count       = 0;
    $news_query  = new WP_Query(array(
        'post_type' => 'news',
        'posts_per_page' => -1,
        'orderby' => 'date',
        'order' => 'ASC',
        'company' => $company
    ));
    $total_count = $news_query->post_count;
    while ($news_query->have_posts()):
        $news_query->the_post();

        $count++;

        $tag_id = get_query_var('tag_id');

        if ($tag_id && $tag_id == '14') {
            // ID 14

        } else if ($tag_id && $tag_id == '13') {
            // ID 13


        } else if ($tag_id && $tag_id == '12') {
            // ID 12


        }
    endwhile;
}
?>

All the tags is inside the query, it is possible to check for this via get_query_var(); all objects inside the query.
For the tag ID ask with this code: get_query_var( 'tag_ID' ); Also it is possible to check for tags, like get_query_var( 'term' ) and the taxonomy get_query_var( 'taxonomy' )

So you can create an Loop with your tag data form your taxonomy; like

$wpq = array ( 
    'post_type' => 'post',
    'post_status' => 'published',
    'taxonomy'=> get_query_var( 'taxonomy' ),
    'term'=> get_query_var( 'term' )
);
$query = new WP_Query( $wpq );
while ( $query->have_posts() ) : $query->the_post();

So you can check:
if ( 'your_tad_id=== get_query_var( ‘tag_ID’ ) ) `

• An hint; if you will use the check via $_REQUEST-var; please filter this data or use only for if statements.
