我正在尝试从 WordPress 安装中的数据创建一个 vcard（我假设 WP 部分无关紧要）。我正在使用类似 URL 参数调用该文件，/inc/vcard.php?vcard=664并且到目前为止具有以下代码：
<?php ob_start();
define( 'WP_USE_THEMES', false );
require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-blog-header.php' );
/**
* Loads the WordPress environment and template.
*
* @package WordPress
*/
if ( !isset($wp_did_header) ) {
$wp_did_header = true;
require_once( dirname(__FILE__) . '/wp-load.php' );
wp();
require_once( ABSPATH . WPINC . '/template-loader.php' );
}
if (isset($_GET['vcard'])) {
$attorney_id = $_GET['vcard'];
$post = get_post($attorney_id);
$slug = $post->post_name;
if (!$post || get_post_type() !== 'attorneys') {
echo 'Invalid attorney';
return;
}
function field_check($field) {
echo get_field($field) ? get_field($field) : '';
}
?>

<?php header('Content-Type: text/x-vcard; charset=utf-8');header('Content-Disposition: attachment; filename="' . $slug . '.vcf"'); exit();
}
else {
echo 'Invalid input.';
}
$output = ob_get_contents();
ob_end_clean();
echo $output;
但似乎输出缓冲工作不正常，或者我仍然没有连接如何一起使用两者（标题和输出缓冲）。任何帮助将不胜感激。谢谢！
快速说明一下，我在 WordPress 之外调用此函数，这就是为什么我在输出缓冲区启动后“包含”WordPress。
更新
在这两个建议之后（将标题设置在缓冲区之外并将其移动exit();到底部，没有任何区别：
<?php ob_start();
define( 'WP_USE_THEMES', false );
require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-blog-header.php' );
/**
* Loads the WordPress environment and template.
*
* @package WordPress
*/
if ( !isset($wp_did_header) ) {
$wp_did_header = true;
require_once( dirname(__FILE__) . '/wp-load.php' );
wp();
require_once( ABSPATH . WPINC . '/template-loader.php' );
}
if (isset($_GET['vcard'])) {
$attorney_id = $_GET['vcard'];
$post = get_post($attorney_id);
$slug = $post->post_name;
if (!$post || get_post_type() !== 'attorneys') {
echo 'Invalid attorney';
return;
}
function field_check($field) {
echo get_field($field) ? get_field($field) : '';
}
?>

更新#2
我已经对代码进行了更多修改，以确保任何地方都没有杂散线：
<?php ob_start();
$slug = 'vcard';
define( 'WP_USE_THEMES', false );
require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-blog-header.php' );
/**
* Loads the WordPress environment and template.
*
* @package WordPress
*/
if ( !isset($wp_did_header) ) {
$wp_did_header = true;
require_once( dirname(__FILE__) . '/wp-load.php' );
wp();
require_once( ABSPATH . WPINC . '/template-loader.php' );
}
if (isset($_GET['vcard'])) {
$attorney_id = $_GET['vcard'];
$post = get_post($attorney_id);
$slug = $post->post_name;
if (!$post || get_post_type() !== 'attorneys') {
return 'Invalid attorney';
}
function field_check($field) {
echo get_field($field) ? get_field($field) : '';
}
?>
BEGIN:VCARD
VERSION:3.0
REV:<?php echo get_the_date(); ?>

END:VCARD<?php
}
else {
return 'Invalid input.';
}
$output = ob_get_contents();
header('Content-Type: text/x-vcard');
header('Content-Disposition: attachment; filename='.$slug.'.vcf');
return $output;
exit();
但仍然没有得到任何地方。我确实注意到没有“标头已发送”消息，但在尝试加载时“找不到网页”。如果我取出标头调用，这是我得到的一些示例输入：

现在这是在源视图中，但在浏览器中它都在一行上——在将标题呈现为 vcard 时这有关系吗？谢谢！
