hey guys i made an attachement download code but for some reason instead of having image.jpg it gives image.jpg.html and it's invalide ...

 

    $mbox = imapOpen();
    if (!$mbox)
    {
        $message = "This link is not valid anymore. Please login again.";
        die("<META HTTP-EQUIV='Refresh' CONTENT='0;url=?mod=mail&message=" . urlencode($message) .
            "'></META>");
    }
    $msg = $_GET['num'];
    $bypasscheck = 0;
    if (!eregi("^([0-9]*)$", $msg) or !eregi("([0-9\.]*)", $_GET['part']))
        exit();
    $tmpa = array();
    $ret = array();
    if (eregi("([0-9\.]*)\.([0-9\.]*)", $_GET['part'], $ret))
    {
        $pone = ($ret[1] - 1);
        $ptwo = ($ret[2] - 1);
    }
    else
    {
        $pone = ($_GET['part'] - 1);
    }
    $dpara = array();
    $struct = @imap_fetchstructure($mbox, $msg);
    $body = @imap_fetchbody($mbox, $msg, $_GET['part']);
    @imap_close($mbox);
    $tmpa = $struct->parts;
    if (isset($ptwo))
    {
        $tmpa = $tmpa[$pone]->parts;
        $obj = $tmpa[$ptwo];
    }
    else
    {
        $obj = $tmpa[$pone];
    }
    $dpara = $obj->dparameters;
    for ($v = 0; $v < sizeof($dpara); $v++)
    {
        if (eregi("filename", $dpara[$v]->attribute))
        {
            $fname = $dpara[$v]->value;
        }
    }
    if (empty($fname))
    {
        $para = $obj->parameters;
        for ($v = 0; $v < sizeof($para); $v++)
        {
            if (eregi("name", $para[$v]->attribute))
            {
                $fname = $para[$v]->value;
            }
        }
    }
    if (empty($fname))
    {
        $disp = $obj->description;
    }
    if (empty($fname))
    {
        $fname = $lang_unknown;
    }
    $mime_type = mimetype($obj->type) . "/" . strtolower($obj->subtype);
    if ($mime_type == "message/rfc822")
    {
        $mime_type = "text/plain";
    }
    header("Content-Type: " . $mime_type);
    switch ($obj->encoding)
    {
        case 4:
            $body = @imap_qprint($body);
            break;
        case 3:
            $body = @imap_base64($body);
            break;
        default:
            $beginning = substr($body, 0, 50);
            if (stristr($beginning, "BinHex") != false)
                $fname = $fname . ".binhex";
            break;
    }
    header("Content-Disposition: attachment; filename=\"$fname\"");
    print $body;

 

The link to access this looks like:

index.php?mod=mail&CMD=Attachview&num=17&part=4

Guys ... this is frustrating ... i completly remade my code ... and i have exacly the same problem ... what is it i don't get? Both of the codes are implemented in other applications and should be working ...

 

function get_attached_file($mbox,$structure,$k,$mid)
{
$encoding = $structure->parts[$k]->encoding;
//extract file name from headers
$fileName = strtolower($structure->parts[$k]->dparameters[0]->value);
//extract attachment from email body
$fileSource = base64_decode(imap_fetchbody($mbox, $mid, $k+1));

//get extension
$ext = substr($fileName, strrpos($fileName, '.') + 1);
//die($ext);

//get mime file type
switch ($ext) {

Have you tried debugging it and see where the name gets skewed? If it is from the imap, chances are your mail server is doing it.

 

If the file has .jpg.html chances are it is not suppose to be .html.  A simple replace of that would suffice.

 

Anyhow see where it gets changed, if it is that way from the get go. If it is, check with your mail service provider as they may know what is going on and what attachments are being returned as .html

Ok i got it to work ... but now it outputs an empty file

 

$mbox = imapOpen();

if (!$mbox){

 die("<META HTTP-EQUIV='Refresh' CONTENT='0;url=?mod=mail&message=".urlencode($message)."'></META>");
}else{

$mid = $_GET['num'];
$k = $_GET['part']-1;	
$structure = imap_fetchstructure($mbox, $mid);
$encoding = $structure->parts[$k]->encoding;

//extract file name from headers
$fileName = strtolower($structure->parts[$k]->dparameters[0]->value);

//extract attachment from email body
$fileSource = base64_decode(imap_fetchbody($mbox, $mid, $k+1));

//get extension	
$ext = substr($fileName, strrpos($fileName, '.') + 1);

//get mime file type
switch ($ext) {

                       )

               )

       )

)

index.php?mod=mail&CMD=Attachview&num=17&part=3

i just tryed this

 

$mid = $_GET['num'];
$k = $_GET['part']-1;

$parttypes = array ("text", "multipart", "message", "application", "audio", "image", "video", "other");

// Load variables only if an external configuration was not selected.

function returnAttachment($itemId, $attachId) {
global $parttypes, $accountUser, $accountPass, $mbox;
$msgStructure = imap_fetchstructure($mbox, $itemId);
$part = $msgStructure->parts[$attachId-1];
$ctype = $parttypes[$part->type]."/".$part->subtype;
$filename = "filename";
foreach($part->parameters as $param) {
	if($param->attribute=="NAME")
		$filename = $param->value;
}
header("content-type: ".$ctype);
header("content-disposition: attachment; filename=".$filename);
// Returned data depends on whether the attachment is binary or text
if($part->type>0) {
	// Binary attachment - convert from base64 to binary
	echo base64_decode(imap_fetchbody($mbox, $itemId, $attachId));
} else {
	// Text attachment - just display it as-is
	echo imap_fetchbody($mbox, $itemId, $attachId);
}
}

echo returnAttachment($mid, $k);

 

It's even worse ... i don't get it ... those are codes posted everywhere as working ...

This code returns an HTML file type + name of the file is by delfault in the code filename and the file returned is corrupted

 

 

Sorry it's just that when the message is down the page (and has some replys to it) nobody opens it so when it's down i bump it so that somebody hopefully sees this and has the answer i am looking for.

All fine and well, except that earliest topic visible in PHP Help section is from 18:49. You've bumped your twice after that. So it was visible on first page. Besides, regular forum users browse also beyond first page.

 

Patience. By bumping beyond reason, you're only annoying those who could help you.

This thread is more than a year old. Please don't revive it unless you have something important to add.
