全局页面ID变量为空错误

我正在创建主题，我需要在主题中创建全局变量functions.php 文件

目前我是这样做的：

/**
 * Setup globals
 */
global $nb_id, $nb_page;

$nb_id = get_the_ID();
// Prepare & set fallback
$globals_array  = array(
    \'nb_id\'     => $nb_id,
    \'nb_page\'   => array(
        \'id\'    => $nb_id,
        \'end\'   => \'front\',
        \'name\'  => \'home\',
        \'type\'  => \'page\'
    )
);

// Set each value from globals array as global $var;
foreach ($globals_array as $name => $value) {
    global $$name;
    $$name              = $value;
    $_GLOBALS[$name]    = $value;

    // Set user view of page
    if($name == \'nb_page\'){
        if(is_admin()) $$name[\'end\']    = \'back\';
        $$name[\'name\']      = $nb_pagenow;
        // Determine if is page or single post
        if(is_single()) $$name[\'type\']  = \'single\';

        $_GLOBALS[$name]    = $$name;
    }
}

问题是我无法使用get_the_ID(), $wp_query->get_queried_object_id() 甚至$wp->public_query_vars 具有page_id.

当前所有场景都返回以下值：

get_the_ID() = null
$wp_query->get_queried_object_id() = 0
$wp->public_query_vars = "page_id" [34]=> string(5) "error"functions.php!?

/** * Setup globals */ global $nb_id, $nb_view, $nb_page; function nb_setup_globals(){ global $post, $nb_id, $nb_view, $nb_page; // Set default vars for globals $nb_id = $post->ID; $nb_view = \'front\'; $nb_post_name = \'index\'; $nb_post_type = \'post\'; // Post type page if(is_page()){ if(nb_get_template_slug()){ $nb_post_name = nb_get_template_slug(); }else{ $nb_post_name = \'page\'; } $nb_post_type = \'page\'; } // Post type post / custom post if(is_single()){ $nb_post_name = $post->post_type; } // View if(is_admin()) $nb_view = \'back\'; // Before globals set default vars one last time $globals_array = array( \'nb_page\' => array( \'id\' => $nb_id, \'name\' => $nb_post_name, \'type\' => $nb_post_type ) ); /** * Let the magin GLOBALS be registered */ foreach ($globals_array as $name => $value) { global $$name; $$name = $value; } } add_action( \'template_redirect\', \'nb_setup_globals\' );

Organize functions.php

组织职能的最佳方式是什么。php的性能？我有几个add\\u操作调用、几个add\\u主题支持、几个add\\u过滤器和4个附加函数。对于面包屑、样式表、注册菜单和小部件。我们是否需要遵守订单？例如，首先是所有add\\u过滤器函数，然后是add theme\\u support等。不确定添加代码是否相关，因为这是一个一般性问题。如果需要，我很乐意更新这篇文章。
