In this Pro tutorial we are going to prefilter the posts using a date query to those published today and conditionally output the Bricks Section having the Posts element/Query Loop only if there is at least 1 published post today.

Additionally, we shall programmatically add “s” at the end of “Today’s Article” if there is more than 1 post published today.

Add a Section having a Today's Article Heading and Posts element.

Add the following in child theme‘s functions.php (w/o the opening PHP tag) or a code snippets plugin:

// Function to get the count of number of posts published today.
function bl_get_today_post_count() {
  $args = array(
    'date_query' => array(
      array(
        'year'  => date( 'Y' ),
        'month' => date( 'm' ),
        'day'   => date( 'd'  ),
      ),
    ),
  );
  
  $query = new WP_Query( $args );

  return $query->found_posts;
}

// Prefilter posts to those published today.
add_filter( 'bricks/posts/query_vars', function( $query_vars, $settings, $element_id ) {
  $date_query = array(
      array(
          'year' => date( 'Y' ),
          'month' => date( 'm' ),
          'day'   => date( 'd' ),
      )
  );

  if ( 'svjwaz' === $element_id ) {
      $query_vars['date_query'] = $date_query;
  }

  return $query_vars;
}, 10, 3 );

// Add "s" at the end of a specific heading element's text if there is more than 1 post published today.
add_filter( 'bricks/element/settings', function( $settings, $element ) {
  if ( $element->id === 'qjkndd' && bl_get_today_post_count() > 1 ) {
      $settings['text'] .= 's';
  }

  return $settings;
}, 10, 3 );

Replace svjwaz with the Bricks ID of your Posts element or the Query Loop element.

Replace qjkndd with the Bricks ID of your Heading element.
