如何在不使用SMTP或登录特殊电子邮件帐户的情况下通过PHP表单上传发送多个图像?
我的代码仅适用于一个File类型的输入,我想使用4个输入才能显示邮件中的所有4张图像。
当我尝试添加多个文件输入时,会收到“电子邮件发送错误”。
我该怎么办?
这是我的代码:
<form action="sendmail.php" method="post" name="mainform" enctype="multipart/form-data">
<table width="500" border="0" cellpadding="5" cellspacing="5">
<tr>
<th>Attach Your File</th>
<td><input name="attachment" type="file"></td>
</tr>
<tr>
<th>Attach Your File</th>
<td><input name="attachment2" type="file"></td>
</tr>
<tr>
<th>Attach Your File</th>
<td><input name="attachment3" type="file"></td>
</tr>
<tr>
<th>Attach Your File</th>
<td><input name="attachment4" type="file"></td>
</tr>
<tr>
<td colspan="2" style="text-align:center;"><input type="submit" name="Submit" value="Send"><input type="reset" name="Reset" value="Reset"></td>
</tr>
</table>
</form>
<?php
$to = $_POST['toEmail'];
$fromEmail = $_POST['fieldFormEmail'];
$fromName = $_POST['fieldFormName'];
$subject = $_POST['fieldSubject'];
$message = $_POST['fieldDescription'];
/* GET File Variables */
$tmpName = $_FILES['attachment']['tmp_name'];
$fileType = $_FILES['attachment']['type'];
$fileName = $_FILES['attachment']['name'];
/* Start of headers */
$headers = "From: $fromName";
if (file($tmpName)) {
/* 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";
}
$flgchk = mail ("$to", "$subject", "$message", "$headers");
if($flgchk){
echo "A email has been sent to: $to";
}
else{
echo "Error in Email sending";
}
?>

发布大量代码并要求对其进行分析并不是很好。 ;-)
通常:尝试将要发送的数据流写入文件,然后对其进行分析-手动或使用某种邮件工具(甚至可能是发出警告的邮件客户端)。尝试手动构造带有多个附件的有效电子邮件,然后尝试使用您的代码重现该格式。
在您的情况下:我看到一个与“具有多个文件的问题”不直接相关的问题,但是与内容类型有关的一个问题(因此,我不是写评论,而是一个答案):charset iso- 8859-1 不应与“ 7bit ”一起使用,而应与“ 8bit”或“ quoted-printable”编码一起使用。
EDIT1:修正不良英语。
EDIT2:再次阅读您的代码。我看不到\ r代表CRLF行尾。
