電子郵件中的PHP附件爲空

Question

我試圖從數據庫中獲取數據並將其顯示爲可下載並通過電子郵件發送給某人的CSV文件。我設法使可下載文件正常工作，並顯示所有正確的數據。它還會將CSV文件發送給必要的人員，但該CSV文件是空的，並且不會顯示任何數據。

這裏是我的代碼：

$myroot = "../../"; 
    include($myroot . "inc/functions.php"); 
     // output headers so that the file is downloaded rather than displayed 
     header('Content-Type: text/csv; charset=utf-8'); 
     header('Content-Disposition: attachment; filename=surveys.csv'); 
     $output = fopen('php://output', 'w'); 
// Create CSV file 
fputcsv($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, $row, ',', '"'); 
} 
fclose($output); 

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

// create the email and send it off 

$subject = "File you requested from RRWH.com"; 
$from = "*****@*****.com"; 
$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

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

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

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

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

'; 
mail("*****@*****.com", $subject, $message, $headers, "-f$from"); 

我花了一天時間，並在此半，但我不能看到問題。有人能告訴我爲什麼附加的CSV文件是空的嗎？

我得到那種絕望，並強調了:(請幫助我的人。

Answer 1

它會幫助你在你的錯誤日誌考慮看看，或者至少設置

ini_set('error_reporting', E_ALL); 
ini_set('display_errors', 1); 

爲會告訴你，BASE64_ENCODE需要一個字符串，但$輸出是一個資源。

嘗試設置

ob_start(); 

的開頭和

$output = ob_get_flush(); 

您FCLOSE & $編碼行之間。

沒有tryed郵件還沒有，但這應該幫助你至少有點:)

我tryed此代碼，一切運作良好：

<?php 
ob_start(); 
header('Content-Type: text/csv; charset=utf-8'); 
header('Content-Disposition: attachment; filename=surveys.csv'); 

$output = fopen('php://output', 'w'); 
fputcsv($output, array('Name', 'Branch', 'Website','Company', 'Question1', 'Question2', 'Question3', 'Question4', 'Question5')); 
$data = array(); 
$data[] = array('Name', 'Branch', 'Website','Company', 'Question1', 'Question2', 'Question3', 'Question4', 'Question5'); 

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

$output = ob_get_flush(); 

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