自定义帖子类型显示帖子所属类别

Question

I have a custom post type advice and taxonomy adcat . I want to display all post belong to that category.

Lets say I have 4 categories namely : 'games', 'tours', 'dishes', 'hotels' and also this four category is a menu. If I click one of the category for example: hotels all post belong to the hotels should display.

By the way this code I used to show wordpress default categories:

<?php $catname = wp_title('', false); ?>
<?php $posts = get_posts("category_name=$catname&numberposts=8&offset=0");
foreach ($posts as $post) : start_wp(); ?>

//html output
<h1><?php the_title(); ?></h1>

<?php endforeach; ?>

this is not working in custom post 'taxonomies' any suggestion would be helpful thank's

Answer 1

try something like this, this is the example to fetch post by category id

$args = array( 'cat' => $cat_id, 'post_type' => 'advice', 'posts_per_page' => -1 );
    $loop = new WP_Query( $args );      
    while ( $loop->have_posts() ) : $loop->the_post();
         the_title();
    endwhile; 
wp_reset_postdata();

you can also use with category name as well.

$args = array('category_name' => 'catname', 'post_type' => 'advice', 'posts_per_page' => -1 );

you can use post_per_page as per your requirement, I have just added -1 for all the posts

Answer 2

I don't really understand your terminology. When you are talking about adcat , is it a custom taxonomy or a term of the build-in taxonomy category . If adcat is a custom taxonomy, you should use the tax_query in WP_Query ,not the category parameters.

Remember, category and a custom taxonomy are both taxonomies, their direct children is called terms, and their direct childen is called child terms

You should also not be using wp_title() to get the queries object. You should be using get_query_var() to get the queried object. For categories it will be cat , taxonomy will be taxonomy and for terms term . Have a look at get_categories , get_taxonomies and get_terms for returned values

Example

$category = get_query_var( `cat` );
$cat_slug = $category->slug;

You can now return $cat_slug to your custom query as category_name

EDIT

I've quickly rethinked the whole thing and checked your comment as well. Why not just copy your index.php and rename it taxonomy.php. There is no need at all for a custom query here. The default loop in taxonomy.php should do it

Not sure if I read your answer correctly but what I am assuming is you want to search posts by the taxonomy terms correct? So in your adcat taxonomy you have 'games', 'tours', 'dishes', 'hotels' as your terms or categories. Your best option would be to use a tax_query in your query arguments. Here is how to do that with the WP_Query() object.

<?php 

$args = array( 
    'post_type' => 'advice',
    'posts_per_page' => 8,
    'tax_query' => array(
    'taxonomy' => 'adcat',
    'terms' => array('games', 'tours', 'dishes', 'hotels'),
    'field' => 'slug'
    )
);

$query = new WP_Query($args); 

if($query->have_posts()) : while($query->have_posts()) : $query->the_post(); ?>

    <h1><?php the_title(); ?></h1>

<?php endwhile; endif; ?>
<?php wp_reset_postdata(); ?>

Important Note: When using a WP_Query you will be overwriting the default post data. So in order to get that data back you just use the wp_reset_postdata() as you can see in the example above after the loop has finished.

try this maybe it work... I write a note so you can see whats going on.. hope it help

<?php
    // Get the term/category of the post
    $terms = get_the_terms( $post->ID , 'advice-cat' );
     foreach ( $terms as $term ) {
     $term_link = get_term_link( $term, 'advice cat' );
    }
    //WordPress loop for custom post type
    $terms = get_the_terms( $post->ID , 'advice-cat' );
     $my_query = new WP_Query('post_type=advice&advice-cat=' . $term->name . '&posts_per_page=-1');
          while ($my_query->have_posts()) : $my_query->the_post(); ?>

     // output content

     <?php the_title(); ?>           


    <?php endwhile;  wp_reset_query(); ?>
