使用PHP在Mail中發送附件

Question

我想使用PHP在郵件中發送文件附件。 下面是我正在使用的代碼，該代碼正在運行，但是每次執行循環時，郵件都將進入單獨的附件中。

/*Uploading docs Array*/
$otherdoc_name = array($_FILES[ 'otherdoc' ][ 'name' ]);
$otherdocCount = count( $_FILES[ 'otherdoc' ][ 'name' ]);         
// print_r($otherdocCount); exit();
for ( $i = 0; $i < $otherdocCount; $i++ ) {
    //Get the temp file path

    $i_types = $_FILES[ 'otherdoc' ][ 'type' ][ $i ];
    $exts = pathinfo( $i_names, PATHINFO_EXTENSION );
    $msgs = '';

    if ( $i_errors == 0 ) {
        if ( $i_sizes > 0 ) {
            $otherdoc_name[$i] = rand() . '.' . $exts;
            $paths = $folder . $otherdoc_name[$i];

            }

        } else {
            $otherdoc_name[$i] = '';
        }

    } else {
        $otherdoc_name[$i] = '';
    }
}

我現在正在將此文件上傳到一個文件夾。 我可以不直接上傳就發送文件嗎？

我希望所有文件都應作為一封郵件發送。 或對我有其他任何不同的邏輯建議。 請幫幫我。

Answer 1

請使用PHPMailer，將其輕松集成到您的應用程序中將非常容易。

從此處下載PHPMailer腳本： http : //github.com/PHPMailer/PHPMailer

解壓縮檔案並將src文件夾復制到項目中的方便位置。

現在，發送帶有附件的電子郵件非常簡單：

require 'phpmailer/src/PHPMailer.php';

use PHPMailer\PHPMailer\PHPMailer;

$email = new PHPMailer();
$email->From      = 'you@example.com';
$email->FromName  = 'Your Name';
$email->Subject   = 'Message Subject';
$email->Body      = $bodytext;
$email->addAddress('destination@example.com');

$email->addAttachment('PATH_TO_YOUR_FILE_HERE');

return $email->send();

僅僅是那一行： $email->addAttachment();

                        }

您可以簡單地將郵件功能帶到循環之外嗎？ 嘗試上面的代碼。 請忽略語法錯誤，因為我尚未對其進行測試。 但是您可以遵循邏輯。

核心PHP中的工作腳本，用於在單個郵件中發送多個附件。
