仅在侧栏中隐藏主页和显示上的帖子

Question

I want to hide posts that belong to a particular category on homepage and let it display only in sidebar.

I can successfully hide posts on homepage but I can't display it in the sidebar.

function exclude_category_home( $query ) {
     if ( $query->is_home ) {
      $query->set( 'cat', '-14' );
    }
    return $query;
 }

 add_filter( 'pre_get_posts', 'exclude_category_home' ){

How can I go about it?

You can create shortcode and add it in sidebar this will work for you. Follow the steps as: In your function.php add following code:

 function wpb_postsbycategory() {
      // the query
     $the_query = new WP_Query( array( 'category_name' => 'announcements', 'posts_per_page' => 10 ) ); 
     // The Loop
      if ( $the_query->have_posts() ) {
           $string .= '<ul class="postsbycategory widget_recent_entries">';
         while ( $the_query->have_posts() ) {
            $the_query->the_post();
                if ( has_post_thumbnail() ) {
                    $string .= '<li>';
                        $string .= '<a href="' . get_the_permalink() .'" rel="bookmark">' . get_the_post_thumbnail($post_id, array( 50, 50) ) . get_the_title() .'</a></li>';
                } else { 
                         // if no featured image is found
                        $string .= '<li><a href="' . get_the_permalink() .'" rel="bookmark">' . get_the_title() .'</a></li>';
                }
             }
    } else {
      // no posts found
    }
     $string .= '</ul>';
     return $string;
        /* Restore original Post Data */
        wp_reset_postdata();
}
  // Add a shortcode
  add_shortcode('categoryposts', 'wpb_postsbycategory');

 // Enable shortcodes in text widgets
 add_filter('widget_text', 'do_shortcode');

 Now Add [categoryposts] shortcode in the text widget and save it.

This might work for you...
