如何在WordPress中根据类别(分类)检索帖子(书)（） _根据分类搜索post

我正在尝试显示特定类别(分类)为” Book1″ 的帖子。
我试图用以下代码显示它。

$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, 不显示任何项目。
#1

$custom_terms = get_terms('Book1'); foreach($custom_terms as $custom_term) { wp_reset_query(); $args = array( 'post_type' => 'book', 'posts_per_page' => 6, 'tax_query' => array( array( 'taxonomy' => 'Book1', 'field' => 'slug', 'terms' => $custom_term-> slug, ), ), ); $loop = new WP_Query($args); if($loop-> have_posts()) { echo '< h2> '.$custom_term-> name.'< /h2> '; while($loop-> have_posts()) : $loop-> the_post(); echo '< a href="'.get_permalink().'"> '.get_the_title().'< /a> < br> '; endwhile; } }

试试这个代码
#2

$args = array( 'post_type' => 'book', 'posts_per_page' => 6, 'tax_query' => array( array( 'taxonomy' => 'Book1', 'field' => ''term_id', // here you are worng name too '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++; } }

//最佳解决方案

< ?php$query = new WP_Query( array( 'post_type' => 'book', // name of post type. 'tax_query' => array( array( 'taxonomy' => 'Book1', // taxonomy name 'field' => 'term_id', // term_id, slug or name 'terms' => 1, // term id, term slug or term name ) ) ) ); while ( $query-> have_posts() ) : $query-> the_post(); // do stuff here.... endwhile; /** * reset the orignal query * we should use this to reset wp_query */ wp_reset_query(); ?>

#3【如何在WordPress中根据类别(分类)检索帖子(书)（）】我是这样做的。谢谢大家

$args = array( 'post_type' => 'book', 'cat' => '35' ); echo '< br> '; $postss = query_posts($args); if ( ! empty( $postss ) & & is_array( $postss ) ) { // Run a loop and print them all ?> < ?php $i=1; foreach ( $postss as $termm ) { ?> < ?php echo ' '.$i.' '.$termm-> post_title. '< br> '; $i++; ?> < ?php } }
