Can’t Get Metabox Data Saved Assistance Needed

The save_post hook is the only one you need, also, your callback function is missing a parameter, check this example:

/**
 * Save post metadata when a post is saved.
 *
 * @param int $post_id The ID of the post.
 */
function save_book_meta( $post_id ) {

    /*
     * In production code, $slug should be set only once in the plugin,
     * preferably as a class property, rather than in each function that needs it.
     */
    $slug = 'book';

    // If this isn't a 'book' post, don't update it.
    if ( $slug != $_POST['post_type'] ) {
        return;
    }

    // - Update the post's metadata.

    if ( isset( $_REQUEST['book_author'] ) ) {
        update_post_meta( $post_id, 'book_author', sanitize_text_field( $_REQUEST['book_author'] ) );
    }

    if ( isset( $_REQUEST['publisher'] ) ) {
        update_post_meta( $post_id, 'publisher', sanitize_text_field( $_REQUEST['publisher'] ) );
    }

    // Checkboxes are present if checked, absent if not.
    if ( isset( $_REQUEST['inprint'] ) ) {
        update_post_meta( $post_id, 'inprint', TRUE );
    } else {
        update_post_meta( $post_id, 'inprint', FALSE );
    }
}
add_action( 'save_post', 'save_book_meta' );

The example can be found in the Codex page for the save_post action hook.
