Question

我一直致力于一个用户在其他用户个人资料页面上传图片的项目。我也成功上传和发送电子邮件，但如果一次上传中有多个文件，它会发送多封电子邮件。

$sendmail = true;

if(!empty($_FILES)){

$team_id = $_GET['param1'];
$user_id = $_GET['param2'];
$id = $_GET['param3'];

$sql = "SELECT * FROM team where team_id = '$team_id'" ;
$sql_result = mysqli_query($conn,$sql) or die ('request "Could not execute SQL query" '.$sql);
while ($row = mysqli_fetch_assoc($sql_result)){
    $abcd = $row; 
} 

$targetDir = "../user_images/";
$fileName = $_FILES['file']['name'];
$fileNamex = substr($fileName, -3);
$fileName = rand(1000,100000).md5($fileName).'_'.$fileName;
$targetFile = $targetDir.$fileName;

if( move_uploaded_file( $_FILES['file']['tmp_name'] , $targetFile ) ){
    mysqli_query($conn, "INSERT INTO gallery (team_id , user_id , id , userPic, token) VALUES('$team_id','$user_id','$id','$fileName','0')") or die(mysqli_error($conn));

    if($sendmail === true){
        $htmlContent = file_get_contents ("../email_template_header.php"); 
        $registerURL = $siteURL.'/register/';
        if($abcd['claimed'] == '1'){
            $htmlContent .= "New image(s) has been uploaded to your business. Please <a href='$registerURL'>login</a> and approve them";
        }
        else{
            $htmlContent .= "New image(s) has been uploaded to your business. Please <a href='$registerURL'>register</a> to claim your business";
        }
        $htmlContent .= file_get_contents ("../email_template_footer.php"); 

        $to = $abcd['b_email'];

        require '../PHPMailerAutoload.php';

        $mail = new PHPMailer;
        $mail->isSMTP();
        $mail->Host = 'localhost';
        $mail->SMTPAuth = false;
        $mail->SMTPSecure = 'tls';
        $mail->Port = 25;
        $mail->setFrom('mail@abc.com', 'ABC');
        $mail->addAddress($to);
        $mail->isHTML(true);
        $mail->Subject = 'New Image Uploaded';
        $mail->Body = $htmlContent;
        $mail->send();
        $mail->clearAddresses();

        $sendmail = false;
    }
}  
}

这不起作用，因为每个文件都运行完整的代码，http://www.dropzonejs.com/上的默认示例中也没有循环，所以我可以在索引标志的帮助下检查文件是否有已上传或未上传。任何帮助表示赞赏。

Answer 1

Dropzone.options.filedrop = {
  init: function () {
    this.on("complete", function (file) {
      if (this.getUploadingFiles().length === 0 && this.getQueuedFiles().length === 0) {
        doSomething();
      }
    });
  }
};

使用Dropzone JS上传多个文件后发送通知
