推广特定分类的帖子

Question

我有一个名为 "products" 的 CPT。它有不同的类别（汽车、手机、家居、美容等）

我想再创建一个并将其命名为 promoted，并且我希望此类帖子列在其他帖子的顶部。

我现在有一个 pre_get_posts 钩子，如下所示：

add_action( 'pre_get_posts', function ( $q )
{
    // Bail if we are on an admin page or if this is not the main query
    if (    is_admin()
         || !$q->is_main_query() 
    )
        return;

    // Only targets the product-category tax pages
    if ( $q->is_tax( 'product-category' ) ) { 
        $q->set( 'orderby', 'rand' );
    }

    if ( $q->is_home() ) {
        // Set posts_per_page 
        $q->set( 'posts_per_page', get_option( 'zens_home_count' ) );
        // Set custom post type 
        $q->set( 'post_type', 'products' );
        // Set random ordering 
        $q->set( 'orderby', 'rand' );
    }       
});

我该怎么做？

Answer 1

我认为最好的方法是从主查询中完全删除 "vip" post，然后使用自定义查询或通过 the_posts 过滤器。

让我们从主页上的主查询和自定义 post 键入存档页面。我会将所有内容合并到一个操作中以将代码保存在一个地方

add_action( 'pre_get_posts', function ( \WP_Query $q )
{
    // Bail if we are on an admin page or if this is not the main query
    if ( is_admin() )
        return;

    if (  !$q->is_main_query() )
        return;

    // Only targets the product-category tax pages
    if ( $q->is_tax( 'product-category' ) ) { 
        $q->set( 'orderby', 'rand' );
    }

    if ( $q->is_home() ) {
        // Set posts_per_page 
        $q->set( 'posts_per_page', get_option( 'zens_home_count' ) );
        // Set custom post type 
        $q->set( 'post_type', 'products' );
        // Set random ordering 
        $q->set( 'orderby', 'rand' );
    }   

    if (    $q->is_home()
         || $q->is_post_type_archive( 'products' )
         || $q->is_tax( 'product-category' )
    ) {
        // Bail on the vip page
        if ( !$q->is_tax( 'product-category', 'vip' ) ) { // Make sure about slug
            $tax_query = [
                [
                    'taxonomy' => 'product-category',
                    'terms'    => 27,
                    'operator' => 'NOT IN'
                ]
            ];
            $q->set( 'tax_query', $tax_query );
        }
    }
});

现在我们可以将 post 加回来

选项 1

通过 the_posts 过滤器

add_filter( 'the_posts', function ( $posts, \WP_Query $q )
{
    if ( !is_admin() )
         return $posts;

    if ( !$q->is_main_query() )// Only target the main query
        return $posts;

    if (    !$q->is_paged()      // Only target the first page
         && (    $q->is_home()   // Only target the home page OR
              || $q->is_post_type_archive( 'products' )  // Only target the post type archive page OR
              || $q->is_tax( 'product-category' )        // Only target the taxonomy archive page AND
            )
    ) {
        // Bail on vip tax pages
        if ( $q->is_tax( 'product-category', 'vip' ) )
            return $posts;

        // Lets get all vip posts
        $args = [
            'posts_per_page' => -1,
            'post_type'      => 'products',
            'orderby'        => 'rand', // Order these posts randomly
            'tax_query'      => [
                [
                    'taxonomy' => 'product-category',
                    'terms'    => 27
                ]
            ]
        ];
        $vip_posts = get_posts( $args );

        // Make sure we have vip posts, if not, we bail
        if ( !$vip_posts )
            return $posts;

        // OK, we have vip posts, lets add them infront of the loop
        $posts = array_merge( $vip_posts, $posts );
    }

    return $posts;
}, 10, 2 );

为此，为了保持 vip 广告独立，我们可以运行循环一次只显示 vip 广告，倒回循环然后再次运行只显示普通广告

if ( have_posts() ) {
    // Run the loop to display vip ads
    while ( have_posts() ) {
        the_post();

            if ( has_term( 27, 'product-category' ) ) {
                // Add your markup and stuff here for vip ads
            }
    } // end our vip ads loop

    rewind_posts(); // Set the counter back to 1 so we can rerun the loop

    while ( have_posts() ) {
        the_post();

            if ( !has_term( 27, 'product-category' ) ) {
                // Your normal markup to display all ads
            }
    }
}

选项 2

通过自定义查询

$args = [
    'posts_per_page' => -1,
    'post_type'      => 'products',
    'orderby'        => 'rand', // Order these posts randomly
    'tax_query'      => [
        [
            'taxonomy' => 'product-category',
            'terms'    => 27
        ]
    ]
];
$vip_posts = new WP_Query( $args );

// Run the loop
if ( $vip_posts->have_posts() ) {
    while ( $vip_posts->have_posts() ) {
        $vip_posts->the_post();

        // Display what you want in your loop like
        the_title();
        echo '</br>';

    }
    wp_reset_postdata();
}
