Would you please re-write your question as clearly as possible? It's a hard task to understand the exact issue right now, but if you describe it clearly (with an example, if possible), I'm sure we will be able to assist you further.

 

OK ,Now i have a form to download an attachment like images ,pdf and doc files ,This files stored in media folder included many folders with numbers of the tasks ,the link of download is

<a href="download.php?path=<?php echo $TaskPost[$s]->id ;?>&compid=<?php echo $TheTask->compid ;?>&type=2">

PHP:

The type =2 here i check which type of folder i will download the attach from it
the download.php

<?php 
session_start();
include("global.php");
$path = strip_tags(intval($_GET["path"])) ;
$type = strip_tags(intval($_GET["type"])) ;

 $size = filesize($file);
 $name = rawurldecode($name);


 //turn off output buffering to decrease cpu usage
 @ob_end_clean();

PHP:

when i run the code it open the attachment like Unicode characters and didn't download it
there is no errors in error log

$PostTask=postsDalc::getById($path);

PHP:

it is retrieve the data from database and it is working well
i don't know why the file open like that and not downloaded well
help me ,thanks

 

The output of file check attach please

 

You may want to try this code to download files, it works great for me:

$fp=fopen("PATH_TO_YOUR_FILE", "rb");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=NAME_OF_YOUR_FILE");
header("Content-Length: ".filesize(PATH_TO_YOUR_FILE));
fpassthru($fp);

PHP:

 

Did you mean to replace this code

header(" Content-Type: text/html; charset=utf-8");
header("Content-Type: application/force-download");
header('Content-Disposition: attachment; filename="'.$name.'"');
header("Content-Transfer-Encoding: binary");
header('Accept-Ranges: bytes');

PHP:

with your code??

$fp=fopen("PATH_TO_YOUR_FILE", "rb");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=NAME_OF_YOUR_FILE");
header("Content-Length: ".filesize(PATH_TO_YOUR_FILE));
fpassthru($fp);

PHP:

 

You may want to give a try. If that doesn't help, we will at least know other part of code needs to be debugged.

 

Yes i try your code and didn't work ,it is still open the file with Unicode characters

 

OK, so we know the issue is not with headers. Did you try debugging (echocing) some essential variables like $name and others? Maybe your function is trying to open some file which actually doesn't exist (especially if you use rawurldecode, as it can be decoded wrong or not actually encoded at some point in your script).

 

Yes i debugging the code many times and the code open the file exactly and i check the database i see all is alright
