title: Count Posts In A WP Taxonomy
body: <p>I have this code in my functions PHP file which I made from searching forums:</p>
  
  <pre><code>function sc_estio_project_management_count() {
    echo '&lt;div class="estio-counter" style="background-color: #FF5000";&gt;We currently have&lt;br /&gt;' . '&lt;span class="estio-counter-span"&gt;' . esc_html( get_tag(210)-&gt;count ) . '&lt;/span&gt;' . '&lt;br /&gt;vacancies in&lt;br /&gt;Project &lt;br id="estio-counter-break"/&gt;Management&lt;br /&gt;&lt;br /&gt;&lt;a href="/training/job-type/project-management/"&gt;View all vacancies&lt;/a&gt;&lt;/div&gt;';
  }
  add_shortcode( 'estio_project_management_count', 'sc_estio_project_management_count' );
  </code></pre>
  
  <p>The <code>. esc_html( get_tag(210)-&gt;count ) .</code> is great &amp; currently echos out the number of posts within a custom post type. Currently there are 8 job types within the post type, each with an individual ID, i.e the above is '210' so on my front end this says there are currently X amount of jobs available in Project Management.</p>
  
  <p>Can anyone help how I can add all these post 8 job type counts together so I can make a shortcode which echos out the total number of posts? I.e 'We currently have a total of X jobs available')</p>
