下面是一个可以放入脚本中的示例，例如：。import.php 在WordPress安装的根目录中。我们迭代所有marina 帖子（或者不管你的CPT是什么）一批50篇（10000篇帖子太多了，无法一次加载），提取联系人详细信息（你需要确保字段名称正确），然后尝试创建一个用户。

<?php

require \'./wp-load.php\';

set_time_limit( 0 );

$query = new WP_Query;
$paged = 1;

while ( true ) {
    $query->query([
        \'posts_per_page\' => 50,
        \'post_type\'      => \'marina\',
        \'paged\'          => $paged,
    ]);

    if ( ! $query->have_posts() ) {
        break;
    }

    foreach ( $query->posts as $post ) {
        // Assumed meta fields, change to fit your needs
        $name  = trim( get_post_meta( $post->ID, \'name\', true ) );
        $email = trim( get_post_meta( $post->ID, \'email\', true ) );

        // Generate a unique username
        $login = $_login = sanitize_key( $name );
        $i     = 2;

        while ( ! $login || username_exists( $login ) ) {
            $login = "$_login-" . ++$i; 
        }

        // Name parts
        $name_parts = preg_split( \'/ +/\', $name );

        // Attempt to create the user
        $user_id = wp_insert_user([
            \'user_pass\'    => wp_generate_password(),
            \'user_login\'   => $login,
            \'user_email\'   => $email,
            \'display_name\' => $name,
            \'first_name\'   => array_shift( $name_parts ),
            \'last_name\'    => implode( \' \', $name_parts ),
            \'role\'         => \'subscriber\',
        ]);

        if ( ! is_wp_error( $user_id ) ) {
            // do something with user ID?
        } else {
            // something went wrong
        }

        // Free up memory
        clean_post_cache( $post );
    }

    $paged++;
}
