我是新手，在搜索时，我可以找到我面临的问题。 我的问题是：我有这个表格，它应该上传文件，并作为邮件发送。如何显示正在上载的文件的状态。因为，人们只是在不让文件上传的情况下提交表单。 这是我的PHP代码：
<?php
if(isset($_POST['Email']))
{
$to = "<<email id>>";
$fromEmail = $_POST['Email'];
$fromName = $_POST['Name'];
$subject = $_POST['Subject'];
$mess= $_POST['Description'];
$message ="\n From: $fromName
\n Email: $fromEmail
\n Topic Name: $subject
\n Article Details: $mess
\n------------------------------------------------------------
";
/* Start of headers */
$headers = "From: $fromName";
if(isset($_FILES['attachment']['tmp_name']))
{
/* GET File Variables */
if($_FILES['attachment']['size']<25000000)
{
$tmpName = $_FILES['attachment']['tmp_name'];
$fileType = $_FILES['attachment']['type'];
$fileName = $_FILES['attachment']['name'];
if($_FILES['attachment']['size']>0)
{
$message .="\n There is an attachment along with this mail.\n";
/* Reading file ('rb' = read binary) */
$file = fopen($tmpName,'rb');
$data = fread($file,filesize($tmpName));
fclose($file);
/* a boundary string */
$randomVal = md5(time());
$mimeBoundary = "==Multipart_Boundary_x{$randomVal}x";
/* Header for File Attachment */
$headers .= "\nMIME-Version: 1.0\n";
$headers .= "Content-Type: multipart/mixed;\n" ;
$headers .= " boundary=\"{$mimeBoundary}\"";
/* Multipart Boundary above message */
$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mimeBoundary}\n" .
"Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n";
/* Encoding file data */
$data = chunk_split(base64_encode($data));
/* Adding attchment-file to message*/
$message .= "--{$mimeBoundary}\n" .
"Content-Type: {$fileType};\n" .
" name=\"{$fileName}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mimeBoundary}--\n";
}
}
else
{
}
}
$flgchk = mail ("$to", "$subject", "$message", "$headers");
if($flgchk){
echo "<script type='text/javascript'>alert('Success');</script>";
}
else{
echo "Error in Email sending";
}
}
?>

编辑：我正在寻找一种进度条解决方案，我得到了here，但最终得到了以下代码：
<?php
if(isset($_POST['Email']))

$to = "masterpratiksaboo@gmail.com,";
$fromEmail = $_POST['Email'];

$mess= $_POST['Description'];
$message ="\n From: $fromName

我尝试了很多东西，但仍然无能为力。
答案 0 :(得分：0)
如果您想阻止发送没有附件的电子邮件，您应该更改“附件检查”
更改此行：
if(isset($_FILES['attachment']['tmp_name']))
要：
if(!empty($_FILES['attachment']['tmp_name']))
