Question

我必须列出Wordpress自定义帖子类型中的所有帖子，并仅显示通过自定义分类法创建的标题和相应的类别。我的代码就在这里，我在分类法上遇到了一些问题。

<?php
$args = array(
    'post_type' => 'books',
    'posts_per_page' => -1);
$myposts = get_posts( $args );
$terms = get_the_terms( $post->ID , 'category' );
foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
    <h1><?php echo the_title(); ?></h1>
    <p>Category: <?php echo $term->name; ?></p>
<?php endforeach;
wp_reset_postdata();?>

Answer 1

这是您更新的代码，请尝试以下操作：

<?php
$args = array(
    'post_type' => 'books',
    'posts_per_page' => -1);
$myposts = get_posts( $args );
$terms = get_the_terms( $post->ID , 'category' );
foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
    <h1><?php echo the_title(); ?></h1>
    <?php $categories = get_the_category( $post->ID ); ?>
    <?php if( ! empty( $categories ) ): ?>
        <?php foreach( $categories as $category ): ?> 
            <p>Category: <?php echo $category->name; ?></p>
            <?php break; ?>
        <?php endforeach; ?>
    <?php endif; ?>
<?php endforeach;
wp_reset_postdata();?>

<?php $args = array(
          'post_type' => 'books',
          'posts_per_page' => -1,       
                'tax_query' => array(
            array(
                'taxonomy' => 'category',
                'field' => 'slug'

            ),
        ),
      );
     $myposts = new WP_Query($args);
     foreach ( $myposts as $post ) : setup_postdata( $post ) ?> 
      <h1><?php echo the_title(); ?></h1>
    <?php $categories = get_the_category( get_the_ID() ); ?>
    <?php if( ! empty( $categories ) ): ?>
        <?php foreach( $categories as $category ): ?> 
            <p>Category: <?php echo $category->name; ?></p>
            <?php break; ?>
        <?php endforeach; ?>
    <?php endif; ?>
<?php endforeach;
wp_reset_postdata();?>

注意： - 现在你将收到所有有类别taxnomoy的帖子。如果您发现任何问题，现在您将以错误的方式进行，您将获得正确的结果。请告诉我。

我明白了！谢谢大家！

<?php
    $terms = get_terms( $post_taxonomy );
    $args = array(
        'post_type' => 'book',
        'posts_per_page' => -1,
        'post_taxonomy' => 'category',
    );
    $the_query = new WP_Query($args);
?>

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

    $category = get_the_terms( $post->ID, "category");
    $category_name = "";
        foreach ( $category as $term ) {
            $category_name .= $term->name.' ';
        }
    ?>

    <h1><?php the_title(); ?></h1>
    <p>Category: <?php echo $category_name; ?></p>


    <?php endwhile;  ?>
<?php endif; ?>
