Question

我创建了一个子菜单来为我的插件添加一些选项字段。据我所知，我已经遵循了文档，并且检查了我可以找到的有关该主题的每条论坛消息。

子菜单已按预期添加到“仪表板”菜单。

选择后，设置页将按预期显示，但是当我填写字段并按Save Changes时，新记录将添加到wp_options表中，但不会保存值。如果我使用SQL手动将值添加到数据库中，则该值显示在字段中，但是如果更改了该值，则不会保存新值。

这是我的代码

<?php // Zuzz Plugin Settings

if (!defined('ABSPATH')) die();

add_action( 'admin_menu', 'create_plugin_settings_page' );

function create_plugin_settings_page() {
    // Add the menu item and page
    $page_title = 'Zuzz Settings Page';
    $menu_title = 'Zuzz Settings';
    $capability = 'manage_options';
    $slug = 'zuzz_settings_page';
    $callback = 'plugin_settings_page_content';
    $icon = 'dashicons-admin-plugins';
    $position = 100;
    add_submenu_page( 'options-general.php', $page_title, $menu_title, $capability, $slug,$callback );
}

function plugin_settings_page_content() {
 ?>
