我正在尝试使用php mail（）将html <input type="file"文档作为附件发送到php电子邮件中。
电子邮件已发送，但附件不在电子邮件中。
以下是相关的HTML：
<td> <label class="custom-file-upload">
<input type="file" onchange="fileNameC()" tabindex="28" id="fileupload" name="fileupload" required/>
<i class="fa fa-cloud-upload"></i>Upload profile</label>
</td>
<td><p id="fileNameT"></p></td>
<td><button id="remove" style="visibility: hidden" onclick="remove();">Remove</button></td>
在HTML中，我使用的是JavaScript函数fileNameC()，下面是该函数的代码：
<script type="text/javascript">
function (){
var file = document.getElementById('fileupload').value;
if(file){
f = file.replace(/.*[\/\\]/, '');
if(confirm("Do you want to select " + f) == true){
document.getElementById("fileNameT").innerHTML = "File " + f + " attached!";
document.getElementById('remove').style.visibility='visible';fileNameC
document.getElementById('remove').style.visibility='inline';
document.getElementById('remove').innerHTML = "Remove :" + f;
}else{
document.getElementById('remove').style.visibility='hidden';
document.getElementById('remove').innerHTML = "";
}
}
}
</script>
和一个remove()函数：
<script type="text/javascript">
function remove(){
document.getElementById('fileupload').value = "";
document.getElementById('remove').style.visibility='hidden';
document.getElementById("fileNameT").innerHTML = " ";
}
</script>
该表单的操作在php中执行：
$fileName = $_FILES["fileupload"]["name"]; // The file name
$fileTmpLoc = $_FILES["fileupload"]["tmp_name"]; // File in the PHP tmp folder
$fileType = $_FILES["fileupload"]["type"]; // The type of file it is
$fileSize = $_FILES["fileupload"]["size"]; // File size in bytes
$fileErrorMsg = $_FILES["fileupload"]["error"]; // 0 for false... and 1 for true
$temp = explode(".",$_FILES["fileupload"]["name"]);
//read from the uploaded file & base64_encode content for the mail
$handle = fopen($fileName, "r");
$content = fread($handle, $fileSize);
fclose($handle);
$encoded_content = chunk_split(base64_encode($content));
$boundary = md5("random"); // define boundary with a md5 hashed value
//header
$headers = "MIME-Version: 1.0\r\n"; // Defining the MIME version
$headers .= "From:".$from_email."\r\n"; // Sender Email
$headers .= "Reply-To: ".$reply_to_email."\r\n"; // Email addrress to reach back
$headers .= "Content-Type: multipart/mixed;\r\n"; // Defining Content-Type
$headers .= "boundary = $boundary\r\n"; //Defining the Boundary
//attachment
$body .= "--$boundary\r\n";
$body .="Content-Type: $file_type; name=".$file_name."\r\n";
$body .="Content-Disposition: attachment; filename=".$file_name."\r\n";
$body .="Content-Transfer-Encoding: base64\r\n";
$body .="X-Attachment-Id: ".rand(1000, 99999)."\r\n\r\n";
$body .= $encoded_content; // Attaching the encoded file with email
$to_email = 'myemail@mysite.com';
$subject = 'Subject';
$body = "Email written content goes here - This part works";
//attachment
$body .= "--$boundary\r\n";
$body .= "Content-Type: text/plain; charset=ISO-8859-1\r\n";
$body .="Content-Disposition: attachment; filename=".$file_name."\r\n";
$body .="Content-Transfer-Encoding: base64\r\n";
$body .="X-Attachment-Id: ".rand(1000, 99999)."\r\n\r\n";
$body .= $encoded_content; // Attaching the encoded file with email
// Always set content-type when sending HTML email
$headers = "MIME-Version: 1.0" . "\r\n";
$headers = "Content-type:text/html;charset=UTF-8" . "\r\n";
// More headers
$headers .= "From: Identykidz Info <" . $from_email . ">\r\n";
//$headers .= 'Cc: myboss@example.com' . "\r\n";
//send email
mail($to_email, "$subject", $body, $headers);
我已尝试以下方法对问题进行排序，
1）我已经检查了error_log并得到了以下内容：
fopen（）：在第11行的/path/to/my/file/myfile.php中文件名不能为空
fread（）期望参数1为资源，在第12行的/path/to/my/file/myfile.php中给出布尔值
fclose（）期望参数1为资源，在第13行的/path/to/my/file/myfile.php中给出布尔值
2）然后，我运行了一个测试以回显$fileName，以查看带到php的文件名，但没有任何显示。
3）我搜索并尝试了其他php代码来创建附件。我不走运。
php文件似乎没有接收到任何文件详细信息。我不明白原因，我已经仔细检查了所有内容，却找不到问题。
请帮助。
