我没有在自定义分类法下发布帖子(fabric_building_types).我也收到了cat_id和cat->name,但无法获取帖子.

 $args = array(
    'type'                     => 'post',
    'child_of'                 => 0,
    'parent'                   => '',
    'orderby'                  => 'name',
    'order'                    => 'ASC',
    'hide_empty'               => 1,
    'hierarchical'             => 1,
    'exclude'                  => '',
    'include'                  => '',
    'number'                   => '',
    'taxonomy'                 => 'fabric_building_types',
    'pad_counts'               => false 
); 

$categories = get_categories( $args );

foreach ( $categories as $cat ) {

    // here's my code for getting the posts for custom post type

    $posts_array = get_posts(
        array(
            'showposts' => -1,
            'post_type' => 'fabric_building',
            'tax_query' => array(
                array(
                    'taxonomy' => 'fabric_building_types',
                    'field' => $cat->cat_ID,
                    'terms' => $cat->name,
                )
            )
        )
    );
    print_r( $posts_array ); 
}

任何人都可以帮助我...提前感谢

I am not getting the posts under custom taxonomy(fabric_building_types). I am getting cat_id and cat->name also but not able to get the posts.

$args = array(
    'type'                     => 'post',
    'child_of'                 => 0,
    'parent'                   => '',
    'orderby'                  => 'name',
    'order'                    => 'ASC',
    'hide_empty'               => 1,
    'hierarchical'             => 1,
    'exclude'                  => '',
    'include'                  => '',
    'number'                   => '',
    'taxonomy'                 => 'fabric_building_types',
    'pad_counts'               => false 
); 

$categories = get_categories( $args );

foreach ( $categories as $cat ) {

    // here's my code for getting the posts for custom post type

    $posts_array = get_posts(
        array(
            'showposts' => -1,
            'post_type' => 'fabric_building',
            'tax_query' => array(
                array(
                    'taxonomy' => 'fabric_building_types',
                    'field' => $cat->cat_ID,
                    'terms' => $cat->name,
                )
            )
        )
    );
    print_r( $posts_array ); 
}

Can anyone please help me out...Thanks in advance

- 税查询中"字段"的有效值是"term_id","名称"或"子弹".
  
  valid values for `field` in a tax query are `term_id`, `name`, or `slug`.

您应尽可能使用get_terms()进行分类.

 <?php 
/* Add your taxonomy. */
$taxonomies = array( 
    'fabric_building_types',
);

$args = array(
    'orderby'           => 'name', 
    'order'             => 'ASC',
    'hide_empty'        => true, 
    'exclude'           => array(), 
    'exclude_tree'      => array(), 
    'include'           => array(),
    'number'            => '', 
    'fields'            => 'all', 
    'slug'              => '', 
    'parent'            => '',
    'hierarchical'      => true, 
    'child_of'          => 0, 
    'get'               => '', 
    'name__like'        => '',
    'description__like' => '',
    'pad_counts'        => false, 
    'offset'            => '', 
    'search'            => '', 
    'cache_domain'      => 'core'
); 

$terms = get_terms( $taxonomies, $args );
foreach ( $terms as $term ) {

// here's my code for getting the posts for custom post type

$posts_array = get_posts(
                        array( 'showposts' => -1,
                            'post_type' => 'fabric_building',
                            'tax_query' => array(
                                array(
                                'taxonomy' => 'fabric_building_types',
                                'field' => term_id,
                                'terms' => $term->name,
                                )
                            )
                        )
                    );
    print_r( $posts_array ); 
}
?>

You should use get_terms() for taxonomies when you can.

<?php 
/* Add your taxonomy. */
$taxonomies = array( 
    'fabric_building_types',
);

$args = array(
    'orderby'           => 'name', 
    'order'             => 'ASC',
    'hide_empty'        => true, 
    'exclude'           => array(), 
    'exclude_tree'      => array(), 
    'include'           => array(),
    'number'            => '', 
    'fields'            => 'all', 
    'slug'              => '', 
    'parent'            => '',
    'hierarchical'      => true, 
    'child_of'          => 0, 
    'get'               => '', 
    'name__like'        => '',
    'description__like' => '',
    'pad_counts'        => false, 
    'offset'            => '', 
    'search'            => '', 
    'cache_domain'      => 'core'
); 

$terms = get_terms( $taxonomies, $args );
foreach ( $terms as $term ) {

// here's my code for getting the posts for custom post type

$posts_array = get_posts(
                        array( 'showposts' => -1,
                            'post_type' => 'fabric_building',
                            'tax_query' => array(
                                array(
                                'taxonomy' => 'fabric_building_types',
                                'field' => term_id,
                                'terms' => $term->name,
                                )
                            )
                        )
                    );
    print_r( $posts_array ); 
}
?>

谢谢...但仍然存在相同的问题..空数组..是因为我在获取术语数组时定义自定义帖子类型时做错了什么.

Thanks...but the same issue remains..empty array.. is it because i am doing something wrong in defining custom post type as i am getting the term array..

 global $post; $id = $post->ID;

$cat = get_the_category($id);
$loc = get_the_terms($id, 'taxonomy');
$posts = get_posts(
array('post_type' => 'post',
    'post_status' => 'publish', 
    'posts_per_page' => -1, 
    'category' => $cat[0]->term_id, 
    'tax_query' => array(
        array(
            'taxonomy' => 'location',
            'field' => 'id',
            'terms' => $loc[0]->term_id,
        )
    )
)
);
print_r($posts);

这应该可行.

global $post; $id = $post->ID;

$cat = get_the_category($id);
$loc = get_the_terms($id, 'taxonomy');
$posts = get_posts(
array('post_type' => 'post',
    'post_status' => 'publish', 
    'posts_per_page' => -1, 
    'category' => $cat[0]->term_id, 
    'tax_query' => array(
        array(
            'taxonomy' => 'location',
            'field' => 'id',
            'terms' => $loc[0]->term_id,
        )
    )
)
);
print_r($posts);

this should be works.

获取分配给当前分类法的帖子

您可以在taxonomy-your_tax.php中添加以下代码

 <div class="a-article-wrapper">

                <?php 

                    $terms = wp_get_post_terms( $post->ID, 'your-taxonomy'); 
                    $terms_ids = [];

                    foreach ( $terms as $term ) {
                        $terms_ids[] = $term->term_id;
                    }

                    $args = array(
                        'post_type' => 'your-post-type',
                        'tax_query' => array(
                            'relation' => 'AND',

Getting posts assigned to current taxonomy

You can add below code in taxonomy-your_tax.php

<div class="a-article-wrapper">

                <?php 

                    $terms = wp_get_post_terms( $post->ID, 'your-taxonomy');

                    foreach ( $terms as $term ) {
                        $terms_ids[] = $term->term_id;
                    }

                    $args = array(
                        'post_type' => 'your-post-type',
                        'tax_query' => array(
                            'relation' => 'AND',
                            array(
                                'taxonomy' => 'your-taxonomy',
                                'field'    => 'term_id',
                                'terms'    => $terms_ids
                            )
                        ),
                    );

                    $query = new WP_Query($args);
                    if ( $query->have_posts() ) {
                        while ( $query->have_posts() ) {

您的纳税查询不正确,field应该是您要查询的字段:term_id,name或slug-

 $posts_array = get_posts(
    array(
        'posts_per_page' => -1,
        'post_type' => 'fabric_building',
        'tax_query' => array(
            array(
                'taxonomy' => 'fabric_building_types',
                'field' => 'term_id',
                'terms' => $cat->term_id,
            )
        )
    )
);

Your tax query is incorrect, field should be the field you want to query on: term_id, name, or slug -

$posts_array = get_posts(
    array(
        'posts_per_page' => -1,
        'post_type' => 'fabric_building',
        'tax_query' => array(
            array(
                'taxonomy' => 'fabric_building_types',
                'field' => 'term_id',
                'terms' => $cat->term_id,
            )
        )
    )
);
