Question

我从数据库中提取数据并以表格格式显示在网页上。我在此页面上提供了一个链接，允许用户将此数据下载为CSV文件。到目前为止，这种方法正常工作，当用户跟踪显示数据下方的链接时，它允许他们保存它。

它还会发送一封包含CSV作为附件的电子邮件。但是目前附件中的CSV是空白的，我不知道为什么。

我想要的只是来自数据库的数据，该数据被放入可下载的CSV中，也可以进入附加的CSV，我无法做到。

有人可以帮助我吗？

这是我到目前为止的代码：

// Create CSV file
fputcsv($output, array('Name', 'Branch', 'Website','Company', 'Question1', 'Question2', 'Question3', 'Question4', 'Question5'));

$mysql_connection = db_connect_enhanced('*******','******','******','******');
$query='SELECT * FROM ****.****';
$surveys = db_query_into_array_enhanced($mysql_connection, $query);
$count = count($surveys);
$data = array();
    for($i=0; $i<=$count; $i++){
    $data[] = array($surveys[$i]['FeedbackName'], $surveys[$i]['BranchName'], $surveys[$i]['FeedbackWebsite'], $surveys[$i]['FeedbackCompany'], $surveys[$i]['Question1'], $surveys[$i]['Question2'], $surveys[$i]['Question3'], $surveys[$i]['Question4'], $surveys[$i]['Question5']);  
}

foreach( $data as $row )  
{  
    fputcsv($output, $row, ',', '"');  
}  

$encoded = chunk_split(base64_encode($data));

// create the email and send it off

$subject = "File you requested from RRWH.com";
$from = "***************";
$headers = 'MIME-Version: 1.0' . "\n";
$headers .= 'Content-Type: multipart/mixed;
   boundary="----=_NextPart_001_0011_1234ABCD.4321FDAC"' . "\n";

$message = '

This is a multi-part message in MIME format.

------=_NextPart_001_0011_1234ABCD.4321FDAC
Content-Type: text/plain;
       charset="us-ascii"

Content-Type: application/octet-stream;  name="';

$message .= "surveys.csv";
$message .= '"

Content-Disposition: attachment; filename="';
$message .= "surveys.csv";
$message .= '"

';
$message .= "$encoded";
$message .= '

------=_NextPart_001_0011_1234ABCD.4321FDAC--

';
mail("*************", $subject, $message, $headers, "-f$from");
fclose($output);

感觉我好近，但我看不出答案:(

Answer 1

更改此行：

$message .= "$encoded";

有了这个：

$message .= $encoded;

Answer 2

这只是一个“建议性”答案：

以下是我用来附加文件的内容，它适用于我，它可以帮助您“BASE”自己处理您遇到的问题。

$file_path = "/path_to_your/$file_name";
$file_path_name = "$file_name"; // this file name will be used at receiver end 

$file = fopen($file_path,'rb');
$data = fread($file,filesize($file_path));
fclose($file); 

$rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$rand}x"; 

$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\""; 

$message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message .= "\n\n"; 

$data = chunk_split(base64_encode($data)); 

$message .= "--{$mime_boundary}\n" .
"Content-Type: {$file_path_type};\n" .
" name=\"{$file_path_name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$file_path_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";
