前言

插件越来越复杂，原先一个插件只包括一个功能。最近把各个小功能集成到一起。需要一个插件设置页面。本文记录设置过程。

设置

主文件设置

//设置
require_once(plugin_dir_path(__FILE__) . 'settings.php');

settings.php

目录菜单函数

add_action('admin_menu', 'woo_bbpay_gateway_add_settings_page');

function woo_bbpay_gateway_add_settings_page()
{
        add_submenu_page(
            'options-general.php',
            __('BbPay GateWay', 'woo-bbpay-gateway'),
            __('BbPay', 'woo-bbpay-gateway'),
            'manage_options',
            'woo-bbpay-gateway-settings',
            'woo_bbpay_gateway_render_settings_page'
        );
}

页面函数

function woo_bbpay_gateway_render_settings_page()
{
    // Check if user has sufficient permissions
    if (!current_user_can('manage_options')) {
        return;
    }

    // Save settings
    if (isset($_POST['woo_bbpay_gateway_settings'])) {
        update_option('woo_bbpay_gateway_abpaymerno', sanitize_text_field($_POST['woo_bbpay_gateway_abpaymerno']));
        update_option('woo_bbpay_gateway_abpaykey', sanitize_text_field($_POST['woo_bbpay_gateway_abpaykey']));
        echo '<div class="updated"><p>' . __('Settings saved.', 'woo-bbpay-gateway') . '</p></div>';
    }

    // Retrieve current settings
    $abpaymerno = get_option('woo_bbpay_gateway_abpaymerno');
    $abpaykey = get_option('woo_bbpay_gateway_abpaykey');
?>

    <div class="wrap">
        <h1><?php echo esc_html(get_admin_page_title()); ?></h1>

        <form method="post" action="">

                    </td>
