I want to mark some posts to include them in a featured content slider. For that purpose, I want to include a check box on the new post page, so that if the checkbox is selected the post is marked as featured. Then I can display all marked posts in the slider. How this can be done? Thanks.

  • This is usually done either placing the featured posts in featured category or tagging them with featured tag. It depends on your theme but 99% of the time its either of the tagging or featured category selection. May 25, 2011 at 8:53
  • sticky is also sometimes used for this

You can create your own meta box with a checkbox and only select posts that where checked:

Add metabox code

/* Define the custom box */
add_action( 'add_meta_boxes', 'my_slider_add_custom_box' );

/* Do something with the data entered */
add_action( 'save_post', 'my_slider_save_postdata' );

/* Adds a box to the main column on the Post and Page edit screens */
function my_slider_add_custom_box() {
        __( 'my slider', 'my_slider_textdomain' ),

/* Prints the box content */
function my_slider_inner_custom_box() {
    global $post;
    // Use nonce for verification
    wp_nonce_field( plugin_basename( __FILE__ ), 'my_slider_noncename' );
    $saved = get_post_meta($post->ID,'my_slider_field',true);
    // The actual fields for data entry
    echo '<label for="my_slider_field">';
    _e("Check the box if you want this post to show in the slider", 'myplugin_textdomain' );
    echo '</label> ';
    echo '<input type="checkbox" id="my_slider_field" name="my_slider_field" value="yes"';
    echo  ($saved) ? 'checked': '';
    echo '/>';

/* When the post is saved, saves our custom data */
function my_slider_save_postdata( $post_id ) {
      // verify if this is an auto save routine. 
      // If it is our form has not been submitted, so we dont want to do anything
      if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) 

      // verify this came from the our screen and with proper authorization,
      // because save_post can be triggered at other times

      if ( !wp_verify_nonce( $_POST['my_slider_noncename'], plugin_basename( __FILE__ ) ) )

      // OK, we're authenticated: we need to find and save the data
        $old = get_post_meta($post_id,'my_slider_field',true);
      if (isset($_POST['my_slider_field']) && $_POST['my_slider_field'] == "yes"){
        if (!empty($old)){

Query posts that were checked

$args = array(
    'posts_per_page' => -1
    'meta_query' => array(
            'key' => 'my_slider_field',
            'value' => true
$slider_query = new WP_Query($args);
