PHP attachment in email is empty
(1 answer)
Closed 9 years ago.
Im trying to take data from the database and display it in a CSV file which is both downloadable and emailed to someone. I have managed to get the downloadable file working and it displays all of the correct data. It also sends a CSV file to the necessary person but that CSV file is empty and no data is displayed in it.
Here is my code:
$myroot = "../../";
include($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 = '

$message .= '

mail("*****#*****.com", $subject, $message, $headers, "-f$from");
I've spent a day and a half on this but I cant see the problem. Could someone please point it out to me as to why the attached CSV file is empty?
i'm getting kind of desperate and stressed out :( please someone help me.

Answer 1

base64_encode() expects the parameter to be a string and you give it a (closed) resource.
Try to read the resource into a string, or use file_get_contents or build your string while you write into the resource.
Update:
Try and replace
foreach( $data as $row )
{
fputcsv($output, $row, ',', '"');
}
fclose($output);
$encoded = chunk_split(base64_encode($output));
by
$myoutput = '"Name","Branch","Website","Company","Question1","Question2","Question3","Question4","Question5"';
foreach( $data as $row )
{
$myoutput .= "\"".implode('","',$row)."\"\n";
fputcsv($output, $row, ',', '"');
}
fclose($output);
$encoded = chunk_split(base64_encode($myoutput));
This way, everything you write into your output you also write into a new variable ($myoutput). Since this is a string you can use it with base64_encode().
