php - 排序和显示自定义帖子类型 Wordpress

Question

所以我有一个选项页面，并创建了以下代码:

add_action('admin_menu', 'add_global_custom_options');
add_theme_support( 'post-formats', array( 'Random', 'Order', 'Category' ) );
function add_global_custom_options()
{
    add_options_page('Sort Registrar List', 'Sort Registrar List', 'manage_options', 'functions','global_custom_options');
}

function global_custom_options()
{
    $options = array (
    'random' =>  array(
      'post_type' => 'registrar',
        'posts_per_page' => -1,
        'orderby' => 'rand'
      ),
    'category' =>  array(
      'post_type' => 'registrar',
        'posts_per_page' => -1,
        'orderby' => 'ASC'
      ),
    'menu_order' =>  array(
      'post_type' => 'registrar',
        'posts_per_page' => -1,
        'orderby' => 'DESC'
      )
        );

?>
    <div class="wrap">
        <h2>Sort Registrar List</h2>
        <form method="post" action="">
            <?php wp_nonce_field('update-options') ?>
            <p><strong>Display Randomly:</strong><br />
                <input type="radio" name="random" size="45" value="<?php echo get_option('random'); ?>" />
            </p>
            <p><strong>Display by Category:</strong><br />
                <input type="radio" name="category" size="45" value="<?php echo get_option('category'); ?>" />
            </p>
            <p><strong>Display By Order:</strong><br />
                <input type="radio" name="order" size="45" value="<?php echo get_option('menu_order'); ?>" />
            </p>
            <p><input type="submit" name="Submit" value="Store Options" /></p>
            <input type="hidden" name="action" value="update" />
            <input type="hidden" name="page_options" value="random,category,menu_order" />
        </form>
    </div>
        <?php
}
?>

但是我有点不知道如何让我的页面显示选中的值。它应该随机显示自定义帖子类型 - 按顺序或按类别显示，具体取决于在管理面板的选项页面中选择的内容。

有没有人有办法做到这一点？

设置不是 100% 正确，您从未点击 options.php 来处理更新，并且您忘记了 esc_attr；此示例正在运行，但它需要更多更改才能 100% 完成您需要的操作，但您可以在此处找到有关如何执行此操作的一些线索 How can I set and get the values of a multiple select with the Wordpress settings API for a theme options page? ;
