从函数内部编辑全局变量

我正在开发我的第一个插件，里面有两个独立的函数来完成两个不同的任务。每个函数都添加到不同的挂钩中，一个使用动作，另一个使用过滤器。第二个函数（过滤器）需要能够访问与第一个函数相同的变量，以便我可以根据第一个函数的状态做出决策。我正试图使用Globals（$Globals[\'varname\'））来实现这一点。我的问题是，即使我可以验证（通过我正在进行的http调用）第一个函数是否正在运行。它没有设置全局变量。因此，第二个函数总是以相同的方式执行。我一直在浏览文档和论坛，但似乎找不到答案。这里有人能给我指出一个可靠的方向吗？下面是一些示例代码，但我已经删除了http请求。

<?php

// DEFINE MY PURGE CDN VARIABLE AND SET ITS INITIAL VALUE
$purgeCdnResult = 7;

// THIS FUNCTION SEND THE HTTP REQUEST THAT PURGES THE CDN CACHE
function hw_cdn_purge() {

// SET MY PURGE CDN GLOBAL VARIABLE TO 1
$GLOBALS[\'purgeCdnResult\'] = 1;

// MY HTTP REQUEST CODE GOES HERE
return;
}

// THIS FUNCTION CHECKS THE STATS OF THE GLOBAL PURGE CDN VARIABLE AND CHANGES THE MESSAGE APPROPRIATELY
function update_post_published_message( $messages ) {

if ($GLOBALS[\'purgeCdnResult\'] == 1) {
$messages[\'post\'][6] = sprintf(__(\'Post Published and CDN has been Purged.\'));
} else {
$messages[\'post\'][6] = sprintf(__(\'Post Published :-) -  \'.$GLOBALS[\'purgeCdnResult\'].\' was the statuscode.\'));
}

return $messages;

}

// Now we set that function up to execute when the publish_post action is called
add_action( \'publish_post\', \'hw_cdn_purge\' );

// now we hookup the message changer
add_filter( \'post_updated_messages\', \'update_post_published_message\');

?>`

<?php // This function sends the http request that purges my cdn cache. function hw_cdn_purge() { // My http request code goes here. // After the request the purgeCdnResult variable is set to the status code of the http request. I will demo that manually here. $purgeCdnResult = 200; // I then pass theis variable to an option in the database to keep it beyond this function. update_option( \'purge_response_status\', $purgeCdnResult; return; } // This next function checks the stored status code from the option and changes the displayed message. function update_post_published_message( $messages ) { // First we retrieve our variable from our stored option or set it to 1 if it is not found. $purgeCdnResult = get_option( \'purge_response_status\', 1 ); // Now we check our result and change the messages appropriately. if ($purgeCdnResult == \'200\') { $messages[\'post\'][6] = sprintf(__(\'Post Published and CDN has been Purged. Status Code \'.$purgeCdnResult)); $messages[\'post\'][1] = sprintf(__(\'Post Updated and CDN has been Purged. Status Code \'.$purgeCdnResult)); } else { $messages[\'post\'][6] = sprintf(__(\'Post Published - Error Purging Cache. Status Code \'.$purgeCdnResult)); $messages[\'post\'][1] = sprintf(__(\'Post Updated - Error Purging Cache. Status Code \'.$purgeCdnResult)); } // Finally we update the option to a non-successful value so that we don\'t get false positive results in the future. update_option( \'purge_response_status\', 1); return $messages; } // Now we set the first function up to execute when the publish_post action is called add_action( \'publish_post\', \'hw_cdn_purge\' ); // now we hookup the message changer function add_filter( \'post_updated_messages\', \'update_post_published_message\'); ?>`

Php显示文章循环，而不是页面内容

我的首页显示最新帖子，使用index.php.我的page.php 包含wp_header 在顶部wp_footer 以下，以及介于两者之间的内容：while (have_posts()) : the_post(); get_template_part( \'content\', \'page\' ); endwhile; 我的content-page.php 应该打印出来the_content() 以及the_title() 但它返回所有帖子的内容和标题。我错过了什么？
