wordpress判断是否为分类页面,自定义分类法分类页

wordpress的页面判断都有函数可用，比如判断首页用，

<?php
if(is_home()||is_front_page()){
	/***********/
}
?>

如何判断自定义文章和分类法的页面呢？

<?php
//判断是否为book文章类型的单页
if( is_singular('book') ){
	/***********/
}

/******判断是否为book文章类型的所有文章归档页********/
if( is_post_type_archive('book') ){
	/********************/
}

/***********判断是否为分类法country的分类页***************/
if( is_tax('country') ){
	/****************/
}
?>

<?php
//通过文章ID,分类法名称获取文章所属某分类法的信息
$terms = get_the_terms( $post->ID, 'country' ); 
if ( $terms && ! is_wp_error( $terms ) ) : 
	$draught_links = array();
	foreach ( $terms as $term ) {
		$draught_links[] = $term->name;
	}
	$on_draught = join( ", ", $draught_links );//用逗号分隔
	echo $on_draught;
endif; ?>

<?php 
$terms = get_the_terms( $post->ID, 'country' );
if ( $terms && ! is_wp_error( $terms ) ) :
	$draught_links = array();
	foreach ( $terms as $term ) {
		$draught_links[] = '<a href="'.get_term_link((int)$term->term_id,'mall').'">'.$term->name .'</a>';
	}
	$on_draught = join( ", ", $draught_links );
	echo $on_draught;
endif;
 ?>
