下午好，我的CPT查询有以下问题，我想告诉我帖子的类型、分类法“课程”和最后3篇帖子。在分类法完成之前，查询是正确的，它会显示所有分类法（课程）的帖子。

查询：

<?php 

$the_query = new WP_Query( array(
    \'post_type\'         =>  \'circulares\',
    \'posts_per_page\'    =>  2,
    \'tax_query\'         =>  array(
        \'taxonomy\'      =>  \'curso\',
        \'field\'         =>  \'slug\',
        \'terms\'         =>  \'tercero\',
    ),
));


while ( $the_query->have_posts() ) :
$the_query->the_post(); ?>

<?php the_title(); ?><br>

<?php endwhile;


wp_reset_postdata(); ?>

    add_action( \'init\', \'create_circular_taxonomies\', 0 );


function create_circular_taxonomies() {

        $labels = array(
        \'name\' => _x( \'Cursos\', \'taxonomy general name\' ),
        \'singular_name\' => _x( \'Curso\', \'taxonomy singular name\' ),
        \'search_items\' =>  __( \'Buscar por Curso\' ),
        \'all_items\' => __( \'Todos los Cursos\' ),
        \'parent_item\' => __( \'Curso padre\' ),
        \'parent_item_colon\' => __( \'Curso padre:\' ),

        \'new_item_name\' => __( \'Nombre del nuevo Curso\' ),
);

register_taxonomy( \'curso\', array( \'circulares\' ), array(

        \'labels\' => $labels, 
        \'show_ui\' => true,
        \'query_var\' => true,
        \'rewrite\' => array( \'slug\' => \'cursos\' ),

}

add_action( \'init\', \'circulares\');

function circulares() {
    $labels = array(

        \'edit_item\'         => __( \'Editar circular\' ),
        \'new_item\'          => __( \'Nueva circular\' ),
        \'view_item\'         => __( \'Ver circular\' ),
        \'search_item\'       => __( \'Buscar circulares\' ),
        \'not_found\'         => __( \'No se han encontrado circulares\' ),
        \'not_found_in_trash\'=> __( \'No se ha encontrado circulares en la papelera\' ),
        \'parent_item_colon\' => \'\'                   
    );
