Question

我正在开发一个图库插件。所以我创建了一个自定义帖子类型，在它下面我创建了一个子菜单页面，用于更改图库选项，如边框宽度，边框颜色，边框半径等。当我更新值时，一切正常，但更新通知未显示。我在这里写主要代码。请告诉我什么是问题。

function gallery_setting_pages() {
    add_submenu_page(
        'edit.php?post_type=gallary',
        'Gallery Settings',
        'Settings', 
        'manage_options', 
        'gallery-setting',
        'gallery_option_page_functions'
    );
    }
    add_action('admin_menu','gallery_setting_pages');


if ( is_admin() ) : 

    function ppmscrollbar_register_settings() {
    register_setting('gallery_plugin_options','rt_gallery_options','rt_gallery_validate_options');
    }

 add_action('admin_init','ppmscrollbar_register_settings');



function gallery_option_page_functions() {

    global $rt_gallery_options;

         if ( ! isset ($_REQUEST['updated'] ) )
            $_REQUEST['updated']=false; 
    ?>
        <?php if ( false !==$_REQUEST['updated'] ) : ?>
        <div class="updated fade"><p><strong><?php _e('options saved'); ?></strong></p></div>
        <?php endif; // If the form has just been submitted, this show the notification ?>

        <form method="post" action="options.php">

        <?php $settings=get_option( 'rt_gallery_options', $rt_gallery_options); ?>

        <?php settings_fields('gallery_plugin_options'); ?>

        <table class="form-table">

            <tr valign="top">
                <th scope="row"><label for="cursor_color">Select Gallery Border Color</label></th>
                <td>
                    <input id="cursor_color" type="text" name="rt_gallery_options[cursor_color]"  value="<?php echo stripslashes($settings['cursor_color']); ?>" class="my-color-field" /><p class="description">In a few words, explain what is this.</p>
                </td>
            </tr>


            </table>

            <p class="submit"><input type="submit" value="Save Changes" class="button button-primary" id="submit" name="submit"></p>    

          </form>   

        </div>
    <?php

    }

    function rt_gallery_validate_options( $input ){
       global $rt_gallery_options;

       $settings = get_option( 'rt_gallery_options', $rt_gallery_options );

       //We strip all tags from the text field, to avoid vulnerablilties like XSS

        $input['cursor_color']=wp_filter_post_kses( $input['cursor_color']);

        return $input;

    }
    endif;   //EndIf is_admin()
