如何在插入新帖子时设置自定义字段值？ Wordpress PHP

Question

我的代码有点问题。我想插入带有自定义字段值的新帖子，但是这些自定义字段不是来自Wordpress，而是来自主题。像update_meta_value（）这样的简单解决方案不起作用。我什至找不到主题脚本来设置这些字段的值。我只找到了这些代码中的大部分，在我想要的字段中关注什么。

                array(
                    'id'        => 'movie_default_fields',
                    'type'      => 'select',
                    'class'     => 'chosen',
                    'title'     => esc_html__('Enable Default Fields', 'amy-movie'),
                    'options'   => array(
                        'movie_release'     => esc_html__('Release Date', 'amy-movie'),
                        'movie_duration'    => esc_html__('Duration', 'amy-movie'),
                        'movie_imdb'        => esc_html__('IMDB', 'amy-movie'),
                        'movie_mpaa'        => esc_html__('MPAA', 'amy-movie'),
                        'movie_language'    => esc_html__('Language', 'amy-movie'),
                        'movie_genre'       => esc_html__('Genre', 'amy-movie'),
                        'movie_actor'       => esc_html__('Actor', 'amy-movie'),
                        'movie_director'    => esc_html__('Director', 'amy-movie'),
                    ),
                    'attributes' => array(
                        'multiple' => 'multiple',
                    ),
                    'default'   => array('movie_release', 'movie_duration', 'movie_imdb', 'movie_mpaa', 'movie_language', 'movie_genre', 'movie_actor', 'movie_director')
                ),

if (!empty($custom_fields)) {
    foreach ($custom_fields as $field) {
        if ($field['type'] == 'text') {
            $name = (isset($field['name']) && $field['name'] != '') ? $field['name'] : '';

            $movie_field[] = array(
                'id'    => sanitize_title($name),
                'type'  => 'text',
                'title' => $name,
            );
        }
    }
}

它以特定的自定义帖子类型显示自定义字段的列表。

if (!function_exists('amy_movie_defaults_fields')) {
    function amy_movie_defaults_fields() {
        $default = array(
            'movie_release',
            'movie_duration',
            'movie_imdb',
            'movie_mpaa',
            'movie_language',
            'movie_genre',
            'movie_actor',
            'movie_director'
        );

        return $default;
    }
}

if (in_array('movie_duration', $defaults_fields)) {
    $movie_field[] = array(
        'id'    => 'movie_duration',
        'type'  => 'text',
        'title' => esc_html__('Duration', 'amy-movie'),
        'after' => '<em>min</em>',
    );
}

我试图在自动创建帖子时尝试插入这些值，但不起作用

$post_id = wp_insert_post(array (
   'post_type' => 'amy_movie',
   'post_title' => $info->title,
   'post_content' => $desc->description,
   'post_status' => 'publish',
   'movie_duration' => $info->duration, //simple example
));

我要解决此问题的第一件事是放入手动条目，以确保您正确使用了wp_insert_post（）函数。自己尝试一下，看看是否可行。如果确实如此，那么您只是没有从正确的位置或正确的方式提取所需的值：

$post_id = wp_insert_post(array (
   'post_type' => 'amy_movie',
   'post_title' => 'The Big LeBowski',
   'post_content' => 'Movie Duration: 1h 5m',
   'post_status' => 'publish',
   //'movie_duration' => $info->duration, //try it without this first.  This function would have to be overloaded by the theme for this to work.
));
