File Problem

[ballouta]

Hello

 

I am using IMAP functions to manage some emails. I sent an email with a zip file of 29KB. The function detects the attachment and copy it to an exisiting directory. The problem is that this file becomes 1KB, i downloaded it to test it, it says it is damaged!

 

WHY?

 

parts of the code:

 

$SaveFileDirectory = "/home/gsclteam/public_html/stk/";

 

......

foreach ($attachment as $attach) {

WriteToFile($SaveFileDirectory . $attach['filename'], imap_base64($attach['filedata']));

echo "Attachment found: " . $attach['filename'] . "<br>";

$myf=$attach['filename'];

}

 

Please please Help.

All of your file writing is done in the function "WriteToFile", which you haven't provided code for.  We can not help you without the relevant code.

Here's my code, I know it is alittle bit long. but easy to trace

 

after the code reads emails in my inbox (only one message here), it copies the attachment to a directory, extraxt it, loop over the directory to process some DB issues accodrdingly.

 

<?php

include('CMS/global.inc.php');
$user= $_GET['user'];

$SaveFileDirectory = "/home/gsclteam/public_html/";
function WriteToFile($file,$contents)	{
// IF the contents is empty lets just make it one space
if ($contents=='' || empty($contents))
	$contents = " ";

// $file is the full path to the file
$fh = fopen($file, "w") or die("Could not open file!");
fwrite($fh, $contents) or die("Could not write to file");
fclose($fh);
}


//check for new messages
$mailbox = imap_open("{localhost:143/notls}INBOX", "EMAIL", "PASSWORD")
or die("Can't connect: " . imap_last_error());;

// Check messages
$check = imap_check($mailbox);

// viewing number of messages in inbox
$chec = imap_mailboxmsginfo($mailbox);


$headers = @imap_headers($mailbox) or die("Couldn't get emails");
$numEmails = sizeof($headers); echo "You have $numEmails messages in your mailbox <br><br><br>";

// SHowing headers

//for($j = 1; $j >=1; $j--) 
//{
$j=1;
$header = imap_header($mailbox, $j);
$from = $header->from;
foreach ($from as $id => $object) {
    $fromname = $object->personal;
    echo "<b>From Name:</b> $fromname<br>";
    $fromaddress = $object->mailbox . "@" . $object->host;
    echo "<b>From Address:</b> $fromaddress<br>";
}
$subject = strip_tags($header->subject); 
echo "<b>Subject:</b>$subject </br>";
$date = $header->date;
echo "<b>Date:</b>$date</br>	";

if ($check->Nmsgs=='0')	{
echo "There are no messages that need to be downloaded"; 	
}	else	{

$emailIndex = $j;

/* Lets find the email body */

Please HELP

Have an error condition created if the "contents" of the file is empty...this will let you know that the problem is before the writing of the file...

 

// IF the contents is empty lets just make it one space
if ($contents=='' || empty($contents))
	die("File " . $file . " was sent to be written, but it's empty");

 

If that occurs, then you the problem is probably in the retrieving of the attachment from the mail server.
