Wordpress主题设置页面

Question

我很难让我的“Hello”显示在我创建的主题页面上。这一切至少看起来都是正确的(但显然不是)--我在这里错过了什么？

// Add Theme Options to menu

function add_theme_menu_item() {

add_theme_page("Theme Panel", "Theme Panel", "manage_options", "theme-panel", "initialize_theme_options", null, 99);

}

add_action("admin_menu", "add_theme_menu_item");

 /**
 * Initializes the theme options page by registering the Sections,
  * Fields, and Settings.
 *
 * This function is registered with the 'admin_init' hook.
 */

 function initialize_theme_options() {

// First, we register a section. This is necessary since all future options must belong to one.

add_settings_section(

    // ID used to identify this section and with which to register options
    'main_settings_section',

    // Title to be displayed on the administration page
    'Main Theme Options',

    // Callback used to render the description of the section

    'main_settings_callback', 

    // Page

    'theme-panel'

);

} 

add_action('admin_init', 'initialize_theme_options');

 // end initialize_theme_options

/* ------------------------------------------------------------------------ *
* Section Callbacks
* ------------------------------------------------------------------------ */

/**
* This function provides a simple description for the General Options page. 
*
* It is called from the 'initialize_theme_options' function by being passed as a parameter
* in the add_settings_section function.
*/

function main_settings_callback() {

  echo 'Hello world.';

} 
// end main_settings_callback

Answer 1

这是错误的：

add_theme_page("Theme Panel", "Theme Panel", "manage_options", "theme-panel", "initialize_theme_options", null, 99);

最后两个参数不应该在那里。请在代码库这里中检查此函数。

编辑：

更重要的是，最后一个参数(应该在那里) initialize_theme_options也是错误的，因为它应该是对输出内容的函数的回调。例如，您的main_settings_callback函数。

第二次编辑：

它不起作用，可能是因为在add_settings_section函数的调用中传递了最后一个参数theme-panel，并且这个页面可能不存在。我说的对吗？例如，尝试用general替换这个参数，它将在主设置页面输出。

好的，我知道了。

function initialize_theme_options() {

// First, we register a section. This is necessary since all future options must belong to one.

add_settings_section(

    // ID used to identify this section and with which to register options
    'main_settings_section',

    // Title to be displayed on the administration page
    'Main Theme Options',

    // Callback used to render the description of the section

    'main_settings_callback', 

    // Page

    'theme-panel'

);

do_settings_sections('theme-panel');

}
