将PHP变量传递到Wordpress项目中包含的文件

对于下面的代码，我需要在invoice.php文件中写入所有php变量数据，这样我就可以使用转换后的invoice.pdf的动态数据获得更新后的文件

$invoice_price = get_user_meta( $user_id, "_issuem_leaky_paywall_live_price", TRUE);
$invoice_package = get_user_meta( $user_id, "_issuem_leaky_paywall_live_description", TRUE);
$invoice_number = get_user_meta( $user_id, "_issuem_leaky_paywall_live_subscriber_id", TRUE);
$date = date ('DD-MM-YY');

include ( ABSPATH . 'invoice.php');
require ( ABSPATH . 'pdfcrowd.php');

try
  {
  // create an API client instance
  $client = new Pdfcrowd("apiname", "apikey");
 // converted php file and store the generated PDF inside uploads  
 $fd = fopen( ABSPATH . 'wp-content/uploads/invoice.pdf', 'wb');
 $client->convertFile( ABSPATH . 'invoice.php', $fd );
 fclose($fd);

它只转换了静态内容，没有为发票传递PHP变量数据

事实上，我认为使用converHtml对您更有效。你可以用

$invoice_price = get_user_meta( $user_id, "_issuem_leaky_paywall_live_price", TRUE);
$invoice_package = get_user_meta( $user_id, "_issuem_leaky_paywall_live_description", TRUE);
$invoice_number = get_user_meta( $user_id, "_issuem_leaky_paywall_live_subscriber_id", TRUE);
$date = date ('DD-MM-YY');

include ( ABSPATH . 'invoice.php');
require ( ABSPATH . 'pdfcrowd.php');

try
  {
  // create an API client instance
  $client = new Pdfcrowd("apiname", "apikey");
 // converted php file and store the generated PDF inside uploads  
 $fd = fopen( ABSPATH . 'wp-content/uploads/invoice.pdf', 'wb');
 $client->convertFile( ABSPATH . 'invoice.php', $fd );
 fclose($fd);

ob_start();
include ( ABSPATH . 'invoice.php');
$content = ob_get_clean();

然后在中使用$content作为第一个参数

$invoice_price = get_user_meta( $user_id, "_issuem_leaky_paywall_live_price", TRUE);
$invoice_package = get_user_meta( $user_id, "_issuem_leaky_paywall_live_description", TRUE);
$invoice_number = get_user_meta( $user_id, "_issuem_leaky_paywall_live_subscriber_id", TRUE);
$date = date ('DD-MM-YY');

include ( ABSPATH . 'invoice.php');
require ( ABSPATH . 'pdfcrowd.php');

try
  {
  // create an API client instance
  $client = new Pdfcrowd("apiname", "apikey");
 // converted php file and store the generated PDF inside uploads  
 $fd = fopen( ABSPATH . 'wp-content/uploads/invoice.pdf', 'wb');
 $client->convertFile( ABSPATH . 'invoice.php', $fd );
 fclose($fd);

$client->convertHtml($content,$fd);

这是我得到这个的医生：

我没有使用PDF群组，但看起来您正在将convertFile方法发送给invoice.php文件的原始未更改版本。我认为您需要在包含所有php变量的include语句之后创建一个新的html文件。然后使用该文件作为第一个参数。您好，user3080408，虽然它在本地运行，但在live dev站点上的内容仍然没有获得php值。有什么线索吗？您可以发布与live站点上完全相同的代码吗？一般来说，如果您将代码从一台服务器移动到另一台服务器，并且行为发生了变化，那么您将查看新服务器的环境，以查看是否有干扰。

$invoice_price = get_user_meta( $user_id, "_issuem_leaky_paywall_live_price", TRUE);
$invoice_package = get_user_meta( $user_id, "_issuem_leaky_paywall_live_description", TRUE);
$invoice_number = get_user_meta( $user_id, "_issuem_leaky_paywall_live_subscriber_id", TRUE);
$date = date ('DD-MM-YY');

include ( ABSPATH . 'invoice.php');
require ( ABSPATH . 'pdfcrowd.php');

try
  {
  // create an API client instance
  $client = new Pdfcrowd("apiname", "apikey");
 // converted php file and store the generated PDF inside uploads  
 $fd = fopen( ABSPATH . 'wp-content/uploads/invoice.pdf', 'wb');
 $client->convertFile( ABSPATH . 'invoice.php', $fd );
 fclose($fd);
