我有下面的代码来显示每个选项卡的不同设置。显示的内容取决于url参数action. 当我尝试选择选项卡时，wordpress会给我一个Sorry, you are not allowed to access this page. 错误请参阅下面的代码。

function minutes_settings_content() {
    ?>
    <div class="wrap">

        <div id="icon-themes" class="icon32"></div>
        <h2>Email & SMS Settings</h2>
        <?php settings_errors(); ?>

        <?php $active_tab = isset( $_GET[ \'action\' ] ) ? $_GET[ \'action\' ] : \'email_sms_options\'; ?>

        <h2 class="nav-tab-wrapper">
            <a href="<?php echo esc_url( add_query_arg( array( \'action\' => \'email_sms_options\' ), admin_url( \'edit.php?post_type=wellbeing-minutes&page=minutes-email-settings\' ) ) ); ?>" class="nav-tab">Email & SMS</a>
            <a href="<?php echo esc_url( add_query_arg( array( \'action\' => \'testing_mode_options\' ), admin_url( \'edit.php?post_type=wellbeing-minutes&page=minutes-email-settings\' ) ) ); ?>" class="nav-tab">Testing Mode</a>
        </h2>

        <form action=\'options.php\' method=\'post\'>

            <?php
            if ( $active_tab == \'email_sms_options\' ) {
                settings_fields( \'EmailSmsMinute\' );
                do_settings_sections( \'EmailSmsMinute\' );
            }
            elseif ( $active_tab == \'testing_mode_options\' ) {
                settings_fields( \'wb_minute_testing_mode\' );
                do_settings_sections( \'wb_minute_testing_mode\' );
            }

            submit_button();
            ?>

        </form>
    </div>

    <?php
}
