download script required

[gurmeet]

Hi,
I have a php page; I want a download script….
There is a download button on a page, I want a when a user clicks on this button, dynamically a selected file start downloading. On the same page, without refreshing …
Plz tell me how it’s possible, or give me a link where I can download such script… I searched but not found such coding…

What do you mean by " dynamically a selected file starts downloading"?

Please provide more info and a link to the page

You can't control what a browser does with a file. By default a new page is always loaded when you load a new file in the browser, except when the browser CHOOSES to save that file instead. You might want to look into a "force download [script]", but that's not entirely reliable.

Do you mean you want to click and say download a picture or a file and the normal file "save or open" box pops up. If so this is what I have used.

<?php

// block any attempt to the filesystem
if (isset($_GET['file']) && basename($_GET['file']) == $_GET['file']) {

$filename = $_GET['file'];
$folder = $_GET['folder'];

} else {

$filename = NULL;

} 
// define error message
$err = '<p style="color:#990000">Sorry, the file you are requesting is unavailable.</p>'; 

if (!$filename) {

// if variable $filename is NULL or false display the message
echo $err;

} else {

// define the path to your download folder plus assign the file name
$path = 'images/albums/'.$folder.'/'.$filename;

// check that file exists and is readable
if (file_exists($path) && is_readable($path)) {

// get the file size and send the http headers
$size = filesize($path);
header('Content-Type: application/octet-stream');
header('Content-Length: '.$size);
header('Content-Disposition: attachment; filename='.$filename);
header('Content-Transfer-Encoding: binary');

// open the file in binary read-only mode
// display the error messages if the file cant be opened
$file = @ fopen($path, 'rb');

if ($file) {

// stream the file and exit the script when complete
fpassthru($file);
exit;

} else {

echo $err;

}

} else {

echo $err;

}

}

?>

And then just put a link on the appropriate item to download and in you link tag include the appropriate GET variables for the code to reference. I saved this as a separate page called download.php

is it possible to rename file before downloading?
where to use rename method in this script... i tried but it doesnot works

[fastsol1]

The script is one that I found online previous. I don't know a lot about the file download process but I would think you couldn't rename it automatically cause it's simply getting the current file name and you're not actually doing anything with it to be able to rename it. I know you can name it whatever you want on upload but not sure about download.

[bluewalrus]

This line I think is what is displayed in the save as prompt

header('Content-Disposition: attachment; filename='.$filename);

so change

'.$filename

to whatever you want the file name to be

file_name_is'

You'll probably also need the file extension in there, not sure though post back if it saves without the ext

[gurmeet]

this scripts downloads files, but the image file are not readable.....
when i open downloaded files, it says " preview not available"....

[bluewalrus]

do they have the extension?
