获取类别链接wordpress

Question

I need to echo category link of posts, so here is my query:

<?php
     $args=array(
          'cat' => 3,
          'post_type' => 'post',
          'post_status' => 'publish',
          'posts_per_page' => 3,
          'caller_get_posts'=> 1
        );
       $my_query = null;
       $my_query = new WP_Query($args);
       if( $my_query->have_posts() ) {
           while ($my_query->have_posts()) : $my_query->the_post(); ?>

                ....SOME HTML....

        <?php
              endwhile;
         }
      wp_reset_query();
   ?>

And on the bottom I need button "Show all posts" and it should redirect to subcategory list of post.

Just use Wordpress' function the_category . The second parameter single ensures that only child categories are shown. You can find more details about it in the documentation .
It should work, if you use the code below in your while loop.

<?php
 $postID = get_the_ID();

 the_category(', ', 'single', $postID);
?>

I hope this helps.
