我有一个自定义的帖子类型叫做公文包。它与三种自定义分类法相关联。一切正常。
但是，对于归档页面，我需要添加一些自定义设置。由于项目的限制，我无法编写插件，所有的更改都必须在主题中完成。
我的设置子菜单页面如下（很简单）this guide, 并且设置会显示在页面上，没有问题。现在的问题是他们没有储蓄。
我只添加了一个设置(header_text) 直到我能解决储蓄问题。
我想$option_group 可能是问题所在。
如果我var_dump($_POST) 我得到：
array (size=6)
\'option_page\' => string \'edit.php?post_type=rushhour_projects&page=projects_archive\' (length=58)
\'action\' => string \'update\' (length=6)
\'_wpnonce\' => string \'23c70a3029\' (length=10)
\'_wp_http_referer\' => string \'/wp-admin/edit.php?post_type=rushhour_projects&page=projects_archive\' (length=68)
\'rushhour_projects_archive\' =>
array (size=1)
\'header_text\' => string \'asdf\' (length=4)
\'submit\' => string \'Save Changes\' (length=12)
以下是自定义帖子类型注册：
if ( ! function_exists(\'rushhour_post_type_projects\') ) :
// Add Portfolio Projects to WordPress
add_action( \'init\', \'rushhour_post_type_projects\', 0 );
// Register Portfolio Projects Custom Post Type
function rushhour_post_type_projects()
{
$labels = array(
\'name\' => _x( \'Portfolio\', \'Post Type General Name\', \'rushhour\' ),
\'singular_name\' => _x( \'Project\', \'Post Type Singular Name\', \'rushhour\' ),
\'menu_name\' => __( \'Portfolio Projects\', \'rushhour\' ),
\'name_admin_bar\' => __( \'Portfolio Project\', \'rushhour\' ),
\'archives\' => __( \'Portfolio Archives\', \'rushhour\' ),
\'parent_item_colon\' => __( \'Parent Project:\', \'rushhour\' ),
\'all_items\' => __( \'All Projects\', \'rushhour\' ),
\'add_new_item\' => __( \'Add New Project\', \'rushhour\' ),
\'add_new\' => __( \'Add New\', \'rushhour\' ),
\'new_item\' => __( \'New Project\', \'rushhour\' ),
\'edit_item\' => __( \'Edit Project\', \'rushhour\' ),
\'update_item\' => __( \'Update Project\', \'rushhour\' ),
\'view_item\' => __( \'View Project\', \'rushhour\' ),
\'search_items\' => __( \'Search Projects\', \'rushhour\' ),
\'not_found\' => __( \'Not found\', \'rushhour\' ),
\'not_found_in_trash\' => __( \'Not found in Trash\', \'rushhour\' ),
\'featured_image\' => __( \'Featured Image\', \'rushhour\' ),
\'set_featured_image\' => __( \'Set featured image\', \'rushhour\' ),
\'remove_featured_image\' => __( \'Remove featured image\', \'rushhour\' ),
\'use_featured_image\' => __( \'Use as featured image\', \'rushhour\' ),
\'insert_into_item\' => __( \'Insert into project\', \'rushhour\' ),
\'uploaded_to_this_item\' => __( \'Uploaded to this project\', \'rushhour\' ),
\'items_list\' => __( \'Projects list\', \'rushhour\' ),
\'items_list_navigation\' => __( \'Projects list navigation\', \'rushhour\' ),
\'filter_items_list\' => __( \'Filter projects list\', \'rushhour\' ),
);
$rewrite = array(
\'slug\' => \'portfolio\',
\'with_front\' => true,
\'pages\' => true,
\'feeds\' => true,
);
$args = array(
\'label\' => __( \'Project\', \'rushhour\' ),
\'description\' => __( \'Portfolio projects for Global VDC.\', \'rushhour\' ),
\'labels\' => $labels,
\'supports\' => array( \'title\', \'editor\', \'excerpt\', \'thumbnail\', \'revisions\', ),
\'taxonomies\' => array( \'rushhour_clients\', \'rushhour_locations\', \'rushhour_project_type\' ),
\'hierarchical\' => false,
\'public\' => true,
\'show_ui\' => true,
\'show_in_menu\' => true,
\'menu_position\' => 5,
\'menu_icon\' => \'dashicons-portfolio\',
\'show_in_admin_bar\' => true,
\'show_in_nav_menus\' => true,
\'can_export\' => true,
\'has_archive\' => \'portfolio\',
\'exclude_from_search\' => false,
\'publicly_queryable\' => true,
\'rewrite\' => $rewrite,
\'capability_type\' => \'page\',
);
register_post_type( \'rushhour_projects\', $args );
}
endif;
然后我有一个设置管理子菜单页面的功能。
if ( ! function_exists(\'rushhour_projects_admin_page\') ) :
add_action( \'admin_menu\' , \'rushhour_projects_admin_page\' );
/**
* Generate sub menu page for settings
*
* @uses rushhour_projects_options_display()
*/
function rushhour_projects_admin_page()
{
add_submenu_page(
\'edit.php?post_type=rushhour_projects\',
__(\'Portfolio Projects Options\', \'rushhour\'),
__(\'Portfolio Options\', \'rushhour\'),
\'manage_options\',
\'projects_archive\',
\'rushhour_projects_options_display\');
}
endif;
因此，上述两项工作没有问题。
我认为，问题在于以下用于注册和保存设置的功能中的某些地方：
if ( ! function_exists(\'rushhour_projects_options_display\') ) :
/**
* Display the form on the Rush Hour Projects Settings sub menu page.
*
* Used by \'rushhour_projects_admin_page\'.
*/
function rushhour_projects_options_display()
{
// Create a header in the default WordPress \'wrap\' container
echo \'<div class="wrap">\';
settings_errors();
echo \'<form method="post" action="">\';
var_dump( get_option(\'rushhour_projects_archive\') );
settings_fields( \'edit.php?post_type=rushhour_projects&page=projects_archive\' );
do_settings_sections( \'edit.php?post_type=rushhour_projects&page=projects_archive\' );
submit_button();
echo \'</form></div><!-- .wrap -->\';
}
endif;
add_action( \'admin_init\', \'rushhour_projects_settings\' );
/**
* Register settings and add settings sections and fields to the admin page.
*/
function rushhour_projects_settings()
{
if ( false == get_option( \'rushhour_projects_archive\' ) )
add_option( \'rushhour_projects_archive\' );
add_settings_section(
\'projects_archive_header\', // Section $id
__(\'Portfolio Project Archive Page Settings\', \'rushhour\'),
\'rushhour_project_settings_section_title\', // Callback
\'edit.php?post_type=rushhour_projects&page=projects_archive\' // Settings Page Slug
);
add_settings_field(
\'header_text\', // Field $id
__(\'Header Text\', \'rushhour\'), // Setting $title
\'projects_archive_header_text_callback\',
\'edit.php?post_type=rushhour_projects&page=projects_archive\', // Settings Page Slug
\'projects_archive_header\', // Section $id
array(\'Text to display in the archive header.\')
);
register_setting(
\'edit.php?post_type=rushhour_projects&page=projects_archive\', // $option_group
\'rushhour_projects_archive\', // $option_name
\'rushhour_projects_archive_save_options\'
);
}
/**
* Callback for settings section.
*
* Commented out until settings are working.
*
* @param array $args Gets the $id, $title and $callback.
*/
function rushhour_project_settings_section_title( $args ) {
// printf( \'<h2>%s</h2>\', apply_filters( \'the_title\', $args[\'title\'] ) );
}
/**
* Settings fields callbacks.
*/
function projects_archive_header_text_callback($args)
{
$options = get_option(\'rushhour_projects_archive\');
printf( \'<input class="widefat" id="header_text" name="rushhour_projects_archive[header_text]" type="textarea" value="%1$s" />\',
$options );
}
/**
* Save options.
*/
function rushhour_projects_archive_save_options()
{
if ( isset( $_POST[\'rushhour_projects_archive[header_text]\'] ) )
{
update_option( \'rushhour_projects_archive\', $_POST[\'rushhour_projects_archive[header_text]\'] );
}
}

好吧，所以我对它不起作用感到恼火，决定重写它。我不确定解决方案是什么，但我怀疑有两件事：表单的端点错误（应该是options.php）和$option_group 和$option_name （它们可能没有正确匹配）。
为了子孙后代，我将把我的重写留在这里，希望它能帮助其他人。此版本与以前版本之间存在一些差异。
这现在位于它自己的文件中，因此您将看不到已注册的自定义帖子类型我为页面使用了一个对象example 2 from the WordPress codex.this tutorial, 我更新后使用wp_localize_script() 注入JSON对象以获取一些PHP数据。
public function __construct()
{
add_action( \'admin_menu\', array( $this, \'add_submenu_page_to_post_type\' ) );
add_action( \'admin_init\', array( $this, \'sub_menu_page_init\' ) );
add_action( \'admin_init\', array( $this, \'media_selector_scripts\' ) );
}
/**

public function add_submenu_page_to_post_type()
{
add_submenu_page(
\'edit.php?post_type=rushhour_projects\',
__(\'Portfolio Projects Options\', \'rushhour\'),
__(\'Portfolio Options\', \'rushhour\'),
\'manage_options\',
\'projects_archive\',
array($this, \'rushhour_projects_options_display\'));
}
/**

public function rushhour_projects_options_display()
{
$this->options = get_option( \'rushhour_projects_archive\' );
wp_enqueue_media();
echo \'<div class="wrap">\';
printf( \'<h1>%s</h1>\', __(\'Portfolio Options\', \'rushhour\' ) );
echo \'<form method="post" action="options.php">\';
settings_fields( \'projects_archive\' );
do_settings_sections( \'projects-archive-page\' );
submit_button();
echo \'</form></div>\';
}
/**

public function sub_menu_page_init()
{
register_setting(
\'projects_archive\', // Option group
\'rushhour_projects_archive\', // Option name
array( $this, \'sanitize\' ) // Sanitize

add_settings_section(
\'header_settings_section\', // ID

}

public function sanitize( $input )
{
$new_input = array();
if( isset( $input[\'archive_description\'] ) )
$new_input[\'archive_description\'] = sanitize_text_field( $input[\'archive_description\'] );
if( isset( $input[\'image_attachment_id\'] ) )
$new_input[\'image_attachment_id\'] = absint( $input[\'image_attachment_id\'] );
return $new_input;
}
/**

public function print_section_info()
{
print \'Select options for the archive page header.\';
}
/**

*/
public function archive_description_callback()
{
printf(
\'<input type="text" id="archive_description" name="rushhour_projects_archive[archive_description]" value="%s" />\',
isset( $this->options[\'archive_description\'] ) ? esc_attr( $this->options[\'archive_description\']) : \'\'
);
}
/**

public function header_bg_image_callback()
{
$attachment_id = $this->options[\'image_attachment_id\'];
// Image Preview
printf(\'<div class="image-preview-wrapper"><img id="image-preview" src="%s" ></div>\', wp_get_attachment_url( $attachment_id ) );
// Image Upload Button
printf( \'<input id="upload_image_button" type="button" class="button" value="%s" />\',
__( \'Upload image\', \'rushhour\' ) );
// Hidden field containing the value of the image attachment id
printf( \'<input type="hidden" name="rushhour_projects_archive[image_attachment_id]" id="image_attachment_id" value="%s">\',
$attachment_id );
}
public function media_selector_scripts()
{
$my_saved_attachment_post_id = get_option( \'media_selector_attachment_id\', 0 );
wp_register_script( \'sub_menu_media_selector_scripts\', get_template_directory_uri() . \'/admin/js/media-selector.js\', array(\'jquery\'), false, true );
$selector_data = array(
\'attachment_id\' => get_option( \'media_selector_attachment_id\', 0 )
);
wp_localize_script( \'sub_menu_media_selector_scripts\', \'selector_data\', $selector_data );
wp_enqueue_script( \'sub_menu_media_selector_scripts\' );
}
}
然后只需在以下情况调用对象is_admin() 是真的：
if ( is_admin() )
$my_settings_page = new RushHourProjectArchivesAdminPage();
