我试图显示具有自定义分类法的自定义帖子类型，但我没有任何运气。什么都没有出现。我感谢你的帮助。

帖子类型=横幅

自定义分类法=国家

我要显示的“国家”=阿尔及利亚

我的代码：-

<?php
$slide = new wp_query( array ( \'post_type\' => \'banner\' , \'taxonomy\' => \'country\', \'term\' => \'algeria\', 
                            \'meta_query\' => array( \'relation\' => \'AND\',
                                                                        array(\'key\' => \'page_ads\',\'value\' => \'home\'),
                                                                        array(\'key\' => \'position_ads\',\'value\' => \'top\'))
                            ));

if ( $slide->have_posts() ) : while ( $slide->have_posts() ) : $slide->the_post(); 
$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), \'single-post-thumbnail\' ); 
?>   
<div class="item"><a href="<?php echo get_option("siteurl")?>/order-ads">    
<img src="<?php echo $image[0]; ?>" width="1350" height="515">   
                                </a>
                                </div> 
<?php
                            endwhile; endif;
                            wp_reset_query();
                            echo "</div><br>";
     }
                            ?>
