Question

我需要按类别放置帖子链接，例如：

类别：

类别描述：lorem ipsum


发布链接1

发布链接2

发布链接3

这是我的代码：

<?php
$args=array(
    'type' => 'courses',
    'taxonomy' => 'study_type',
    'orderby' => 'name',
    'order' => 'ASC'
);
$categories=get_categories($args);
foreach($categories as $category) { 
    echo '<h3 class="study-tax-title">'. $category->name .'</h3>';
    echo '<p>'. $category->description . '</p>';
    /*List of links should be here*/
}

我是否需要放置另一个数组并执行wpquery，还是可以通过get_categories数组回显某些内容？

以下是我注册CPT和Tax的方式：

<?php

    // Register Custom Post Type
    function custom_course_post_type() {

        'singular_name'       => _x( 'Course', 'Post Type Singular Name', 'text_domain' ),
        'menu_name'           => __( 'Courses', 'text_domain' ),

Answer 1

如果您要显示一个类别的帖子，则必须使用“ get_posts ”功能（此处有很多示例：http://codex.wordpress.org/Template_Tags/get_posts）

但你可以尝试添加：

$args = array( 'posts_per_page' => 3, 'category' => id_number_of_your_category );
$myposts = get_posts( $args );
echo "<ul>";
foreach( $myposts as $post ) : setup_postdata($post); ?>
   <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; 
echo "</ul>";
?>

希望这是你想要的，并会帮助你！

Answer 2

您可以按照以下方式执行此操作：

$args = array(
    /* 'type' => 'courses', */ 
    /* 'taxonomy' => 'study_type', */ // this only work if you have study_type as taxonomy, default taxonomy is category
    'orderby' => 'name',
    'order' => 'ASC'
);

$categories = get_categories($args);
foreach ($categories as $category) {
    echo '<h3 class="study-tax-title">' . $category->name . '</h3>';
    echo '<p>' . $category->description . '</p>';
    /* List of links should be here */

    $filtered_posts = get_posts(array('numberposts' => 3, 'category' => $category->cat_ID));
    if ($filtered_posts) {
        echo '<ul>';
        foreach ($filtered_posts as $post) {
            echo '<li><a href="' . get_permalink($post->ID) . '">' . $post->post_title . '</a></li>';
        }
        echo '</ul>';
    }
}

* 使用tax_query更新了代码：

$args = array(
    'type' => 'courses',
    'taxonomy' => 'study_type',
    'orderby' => 'name',
    'order' => 'ASC'
);

$categories = get_categories($args);
foreach ($categories as $category) {
    echo '<h3 class="study-tax-title">' . $category->name . '</h3>';
    echo '<p>' . $category->description . '</p>';
    /* List of links should be here */

    $filtered_posts = get_posts(
        array(
            'post_type' => 'courses',
            'tax_query' => array(
                array(
                    'taxonomy' => $category->taxonomy,
                    'field' => 'id',
                    'terms' => $category->term_id
                )
            )
        )
    );
    if ($filtered_posts) {
        echo '<ul>';
        foreach ($filtered_posts as $post) {
            echo '<li><a href="' . get_permalink($post->ID) . '">' . $post->post_title . '</a></li>';
        }
        echo '</ul>';
    }
}
