我正在尝试访问帖子上的信息，这样我就可以获得帖子标题和帖子内容，这样我就可以生成相应的OG标签，放在标题中。问题是该信息仅在loop\\u结束后可用。在那个动作发生后，我怎样才能插入头部呢？

编辑：下面是正在使用的代码

<?php
/**
 * *snip*
 * standard plugin info
 * *snip*
 */

$jobTitle ="";
$jobDescription ="";

function getJobInfo() {
    global $jobTitle,$jobDescription;
    if (is_single()) {
        $jobTitle = get_jobs()->get("job_title");
        $jobDescription = get_jobs()->get("job_description");
    }
}

add_action("loop_end", \'getJobInfo\'); // the info is only available on this hook since this is part of a plugin that modifies some pages.

function generateOGtag(){
    global $jobTitle,$jobDescription;
    echo "<meta property=\'og:title\' content=\'$jobTitle\'>\\n";
    echo "<meta property=\'og:title\' content=\'$jobDescription\'>\\n";
}
add_action("wp_head", \'generateOGtag\'); 

根据wordpress插件参考，它确实指出wp_head 在之前加载loop_end 那么，我如何从loop_end 进入的操作wp_head 行动

function generateOGtag(){
  if (is_single()) {
    global $wp_query;
    if (have_posts()) {
      while (have_posts()) {
        the_post();
        // no idea if your plugin needs anything else here
      }
    }
    $jobTitle = get_jobs()->get("job_title");
    $jobDescription = get_jobs()->get("job_description");
    echo "<meta property=\'og:title\' content=\'$jobTitle\'>\\n";
    echo "<meta property=\'og:title\' content=\'$jobDescription\'>\\n";
    wp_reset_query();
    wp_reset_postdata();
  }
}
add_action("wp_head", \'generateOGtag\');
