I have a Download.php file which can download any types of file. And I have attached here my Download.php :
<?php
@apache_setenv('no-gzip', 1);
@ini_set('zlib.output_compression', 'Off');
$file_path = $_REQUEST['file'];
$path_parts = pathinfo($file_path);
$file_name = $path_parts['basename'];
$file_ext = $path_parts['extension'];
$file_path = './uploads/' . $file_name;
$is_attachment = isset($_REQUEST['stream']) ? false : true;
if (is_file($file_path))
{
$file_size = filesize($file_path);
$file = @fopen($file_path,"rb");
if ($file)
{
header("Pragma: public");
header("Expires: -1");
header("Cache-Control: public, must-revalidate, post-check=0, pre-check=0");
header("Content-Disposition: attachment; filename=\"$file_name\"");
if ($is_attachment)
header("Content-Disposition: attachment; filename=\"$file_name\"");
else
header('Content-Disposition: inline;');
$ctype_default = "application/octet-stream";
$content_types = array(
"exe" => "application/octet-stream",
"zip" => "application/zip",
"mp3" => "audio/mpeg",
"mpg" => "video/mpeg",
"avi" => "video/x-msvideo",
);
$ctype = isset($content_types[$file_ext]) ? $content_types[$file_ext] : $ctype_default;
header("Content-Type: " . $ctype);
if(isset($_SERVER['HTTP_RANGE']))
{
list($size_unit, $range_orig) = explode('=', $_SERVER['HTTP_RANGE'], 2);
if ($size_unit == 'bytes')
{
list($range, $extra_ranges) = explode(',', $range_orig, 2);
}
else
{
$range = '';
header('HTTP/1.1 416 Requested Range Not Satisfiable');
exit;
}
}
else
{
$range = '';
}
list($seek_start, $seek_end) = explode('-', $range, 2);
$seek_end = (empty($seek_end)) ? ($file_size - 1) : min(abs(intval($seek_end)),($file_size - 1));
$seek_start = (empty($seek_start) || $seek_end < abs(intval($seek_start))) ? 0 : max(abs(intval($seek_start)),0);
if ($seek_start > 0 || $seek_end < ($file_size - 1))
{

}
else
header("Content-Length: $file_size");
header('Accept-Ranges: bytes');
set_time_limit(0);
fseek($file, $seek_start);
while(!feof($file))
{
print(@fread($file, 1024*8));
ob_flush();
flush();
if (connection_status()!=0)
{
@fclose($file);
exit;
}
}
@fclose($file);
exit;
}
else
{
header("HTTP/1.0 500 Internal Server Error");
exit;
}
}
else
{
header("HTTP/1.0 404 Not Found");
exit;
}
?>
Now, I need a Ajax code which will execute by a click event in button to download MyFile.exe which exist in the server location: "/files/MyFile.exe".
And I want to add a progress bar to see the progress of downloading.
Please help me by ajax and html code to complete this task.
Thank you.
