我正在尝试显示特定类别(分类法)的帖子，即Book1".

I am trying to display posts of specific category(taxonomy) that is 'Book1'.

我尝试使用以下代码显示它.

I tried to display it with the following code.

                    $args = array(
                        'post_type' => 'book',
                        'posts_per_page' => 6,
                        'tax_query' => array(
                            array(
                                'taxonomy' => 'Book1',
                                'field' => 'id',
                                'terms' => 1
                            )
                        )
                    );
                    echo '<br>';
                    $postss = get_posts( $args );

                    if ( ! empty( $postss ) && is_array( $postss ) ) {
                        // Run a loop and print them all
                        $i=1;
                        foreach ( $postss as $termm ) { 
                                echo ' '.$i.' '.$termm->post_title. '<br>';
                                $i++;
                        }
                    }
               ?>

在输出中没有显示任何项目.

In output no any item is displayed.
