[Resolved] Sticky post loop

Hi, I have a problem
I have a view in which I show only sticky posts.
It works if I set stickyness in the publish meta box, under visibility.
Since my users have some difficulty in finding it there, I created a custom meta box to set stickyness.
But if they check stickyness there, these posts are not taked by Toolset View.

This is the view
hidden link

And this is the meta box code

function sm_custom_meta() {
    add_meta_box( 'sm_meta', __( 'Articolo in evidenza', 'sm-textdomain' ), 'sm_meta_callback', 'post' );
}
function sm_meta_callback( $post ) {
    $featured = get_post_meta( $post->ID );
    ?>
 
  <p>
    <div class="sm-row-content">
        <label for="meta-checkbox">
            <input type="checkbox" name="meta-checkbox" id="meta-checkbox" value="yes" <?php if ( isset ( $featured['meta-checkbox'] ) ) checked( $featured['meta-checkbox'][0], 'yes' ); ?> />
            <?php _e( 'Metti questo articolo in evidenza', 'sm-textdomain' )?>
        </label>
        
    </div>
</p>
 
    <?php
}
add_action( 'add_meta_boxes', 'sm_custom_meta' );



/**
 * Saves the custom meta input
 */
function sm_meta_save( $post_id ) {
 
    // Checks save status
    $is_autosave = wp_is_post_autosave( $post_id );
    $is_revision = wp_is_post_revision( $post_id );
    $is_valid_nonce = ( isset( $_POST[ 'sm_nonce' ] ) && wp_verify_nonce( $_POST[ 'sm_nonce' ], basename( __FILE__ ) ) ) ? 'true' : 'false';
 
    // Exits script depending on save status
    if ( $is_autosave || $is_revision || !$is_valid_nonce ) {
        return;
    }
 
 // Checks for input and saves
if( isset( $_POST[ 'meta-checkbox' ] ) ) {
    update_post_meta( $post_id, 'meta-checkbox', 'yes' );
} else {
    update_post_meta( $post_id, 'meta-checkbox', '' );
}
 
}
add_action( 'save_post', 'sm_meta_save' );

WordPress provides functions that will let you make a post sticky or unsticky:

stick_post( $post_id );
unstick_post( $post_id );

https://codex.wordpress.org/Function_Reference/stick_post

So you could call stick_post or unstick_post in your sm_meta_save function:

if( isset( $_POST[ 'meta-checkbox' ] ) ) {
    update_post_meta( $post_id, 'meta-checkbox', 'yes' );
    stick_post( $post_id );
} else {
    update_post_meta( $post_id, 'meta-checkbox', '' );
    unstick_post( $post_id );
}
