categories - Count how many posts have a specified tag AND category

文章数量:1334133

I know how to count how many posts has a certain tag, or category

For example:

$term_slug = 'some-post-tag';
$term = get_term_by('slug', $term_slug, $post_tag);
echo $term->count;

BUT! Is there anyway to count how many posts that have a tag AND a specified category?

I want to count how many posts that have the tag(slug) "cat" and the category slug "allowpost"

Is this even possible?

Edit: if possible, it would be good if this is manageable via some solution similarly my first script, because this is going to be used on search result pages, and different post pages, so adding something to the loop itself won't work..

You could use WP_Query and specifically a tax_query:

    $args = array(
        'post_type' => 'post',
        'tax_query' => array(
            'relation' => 'AND',
            array(
                'taxonomy' => 'category',
                'field'    => 'slug',
                'terms'    => array( 'allow-list' ),
            ),
            array(
                'taxonomy' => 'post_tag',
                'field'    => 'slug',
                'terms'    => array( 'cats' ),
            ),
        ),
    );
    $the_query = new WP_Query( $args );
    if ( $the_query->have_posts() ) {
      $count = $the_query->found_posts;
      echo 'Post count: ' . $count;
     // echo '<ul>';

     // while ( $the_query->have_posts() ) {
      //  $the_query->the_post();
       // echo '<li>' . get_the_title() . '</li>';
     // }
    //  echo '</ul>';
   } else {
     echo 'No posts found';
   }
/* Restore original Post Data */
wp_reset_postdata();

This solved my issue, originally created by Mr. Prashant Singh @ WordPress forum

$args = array(
  'posts_per_page' => -1,
  'tax_query' => array(
    'relation' => 'AND', // only posts that have both taxonomies will return.
    array(
      'taxonomy' => 'post_tag',
      'field'    => 'slug',
      'terms'    => 'your-tag-slug', //cat
    ),
    array(
      'taxonomy' => 'category',
      'field'    => 'slug',
      'terms'    => 'your-category-slug', //allowpost
    ),
  ),
);
$posts = get_posts($args);
$count = count($posts);
