通過郵件發送日曆請求

Question

我想通過我的php代碼實現日曆請求郵件。我的代碼是這樣的：

$to = "srimanta.chakraborty@fugenx.com"; 
$subject = "Training Registration"; 
$message = "Thank you for participating in the Technical Certification training program."; 
$location = "Conf"; 
//================== 
$headers = "Content-Type:text/calendar; Content-Disposition: inline; charset=utf-8;"; 
$headers .= "Content-Type: text/plain;charset=utf-8"; 
$messaje = "BEGIN:VCALENDAR"; 
$messaje .= "VERSION:2.0"; 
$messaje .= "PRODID:PHP"; 
$messaje .= "METHOD:REQUEST"; 
$messaje .= "BEGIN:VEVENT"; 
$messaje .= "DTSTART:20121223T171010Z"; 
$messaje .= "DTEND:20121223T191010Z"; 
$messaje . "DESCRIPTION: You have registered for the class"; 
$messaje .= "SUMMARY:Technical Training"; 
$messaje .= "ORGANIZER; CN=\"Corporate\":mailto:jayashree.g@fugenx.com"; 
$messaje .= "Location:" . $location . ""; 
$messaje .= "UID:040000008200E00074C5B7101A82E00800000006FC30E6 C39DC004CA782E0C002E01A81\n"; 
$messaje .= "SEQUENCE:0\n"; 
$messaje .= "DTSTAMP:".date('Ymd').'T'.date('His')."\n"; 
$messaje .= "END:VEVENT\n"; 
$messaje .= "END:VCALENDAR\n"; 
$headers .= $messaje; 
mail($to, $subject, $message, $headers); 

通過此代碼我收到了郵件，但沒有按日曆請求格式。此外，郵件已連同附件「Training Registration.ics」文件一起轉發。 我需要接受，暫定，拒絕，建議新的時間，日曆選項以及郵件。 請指導我如何做到這一點。 謝謝。

Answer 1

$headers = 'Content-Type:text/calendar; Content-Disposition: inline; charset=utf-8;\r\n'; 

這裏，嘗試單引號改爲雙引號（「=>」）

這是因爲丁格爾報價會逃跑\ r和\ n

最後，我在下面做了一些建議，並改變了標題，至少它在我的工作方面起作用了。

$to = "srimanta.chakraborty@fugenx.com"; 
$subject = "Training Registration"; 
$message = "Thank you for participating in the Technical Certification training program.\r\n\r\n"; 
$location = "Conf"; 
//================== 
$headers .= "MIME-version: 1.0\r\n"; 
$headers .= "Content-class: urn:content-classes:calendarmessage\r\n"; 
$headers .= "Content-type: text/calendar; method=REQUEST; charset=UTF-8\r\n"; 
$messaje = "BEGIN:VCALENDAR\r\n"; 
$messaje .= "VERSION:2.0\r\n"; 
$messaje .= "PRODID:PHP\r\n"; 
$messaje .= "METHOD:REQUEST\r\n"; 
$messaje .= "BEGIN:VEVENT\r\n"; 
$messaje .= "DTSTART:20121223T171010Z\r\n"; 
$messaje .= "DTEND:20121223T191010Z\r\n"; 
$messaje .= "DESCRIPTION: You have registered for the class\r\n"; 
$messaje .= "SUMMARY:Technical Training\r\n"; 
$messaje .= "ORGANIZER; CN=\"Corporate\":mailto:jayashree.g@fugenx.com\r\n"; 
$messaje .= "Location:" . $location . "\r\n"; 
$messaje .= "UID:040000008200E00074C5B7101A82E00800000006FC30E6 C39DC004CA782E0C002E01A81\r\n"; 
$messaje .= "SEQUENCE:0\r\n"; 
$messaje .= "DTSTAMP:".date('Ymd').'T'.date('His')."\r\n"; 
$messaje .= "END:VEVENT\r\n"; 
$messaje .= "END:VCALENDAR\r\n"; 
$message .= $messaje; 
mail($to, $subject, $message, $headers);
