$wp_query 代码显示不正确

Question

我最近从头开始制作了一个wordpress电影网站，我现在发现很难解决无法正常工作的代码。我遇到的问题是我有一个自定义 post 类型 "movies" 和一些附加到上述 post 类型的自定义元数据，我想做的是列出我的自定义 post按元数据 "released" 的顺序键入 "movies"。这是我的 functions.php 文件的一部分。

add_filter( 'rwmb_meta_boxes', 'your_prefix_meta_boxes' );

function your_prefix_meta_boxes( $meta_boxes ) {
$meta_boxes[] = array(
    'title'      => __( 'Movie Meta Box', 'textdomain' ),
    'post_types' => 'movies',
    'fields'     => array(
        array(
            'id'   => 'name',
            'name' => __( 'Title', 'textdomain' ),
            'type' => 'text',
        ),
        array(
            'id'   => 'released',
            'name' => __( 'Release Date', 'textdomain' ),
            'type' => 'date',
        ),
        array(
            'id'      => 'rating',
            'name'    => __( 'Rating', 'textdomain' ),
            'type'    => 'radio',
            'options' => array(
                '0' => __( 'Unrated', 'textdomain' ),
                '1' => __( '1', 'textdomain' ),
                '2' => __( '2', 'textdomain' ),
                '3' => __( '3', 'textdomain' ),
                '4' => __( '4', 'textdomain' ),
                '5' => __( '5', 'textdomain' ),
                '6' => __( '6', 'textdomain' ),
                '7' => __( '7', 'textdomain' ),
                '8' => __( '8', 'textdomain' ),
                '9' => __( '9', 'textdomain' ),
                '10' => __( '10', 'textdomain' ),
            ),
        ),
        array(
            'id'   => 'duration',
            'name' => __( 'Duration', 'textdomain' ),
            'type' => 'text',
        ),
        array(
            'id'      => 'genre',
            'name'    => __( 'Genre', 'textdomain' ),
            'type'    => 'textarea',
        ),
        array(
            'id'   => 'director',
            'name' => __( 'Director/s', 'textdomain' ),
            'type' => 'textarea',
        ),
        array(
            'id'   => 'writer',
            'name' => __( 'Writer/s', 'textdomain' ),
            'type' => 'textarea',
        ),
        array(
            'id'   => 'stars',
            'name' => __( 'Star/s', 'textdomain' ),
            'type' => 'textarea',
        ),
        array(
            'id'   => 'storyline',
            'name' => __( 'Storyline', 'textdomain' ),
            'type' => 'textarea',
        ),
    ),
);
return $meta_boxes;
}

这是档案-movies.php

使用meta_type定义正确的类型：

'meta_key'  => 'released',
'meta_type' => 'DATE',
'orderby'   => 'meta_value_date',
'order'     => 'DESC'

（此示例假设使用 DATE 格式）

meta_value - Note that a meta_key=keyname must also be present in the query. Note also that the sorting will be alphabetical which is fine for strings (i.e. words), but can be unexpected for numbers (e.g. 1, 3, 34, 4, 56, 6, etc, rather than 1, 3, 4, 6, 34, 56 as you might naturally expect). Use meta_value_num instead for numeric values. You may also specify meta_type if you want to cast the meta value as a specific type. Possible values are NUMERIC, BINARY, CHAR, DATE, DATETIME, DECIMAL, SIGNED, TIME, UNSIGNED, same as in $meta_query. When using meta_type you can also use meta_value_* accordingly. For example, when using DATETIME as meta_type you can use meta_value_datetime to define order structure.
