如何计算用户下载次数

This code for extract files dir and title. The user download when clicked the file link. I need to count then number of downloads. How to do this with cakephp or php?

downloads_controller.php:

function index() {
    $this->set('downloads', $this->paginate());
}

downloads/index.ctp:

<?php
    $title = $download['Download']['title']; 
    // output filetitle 
    $filename = '/files/'.$download['Download']['filename']; 
    // output http://localhost/tet/files/un5titled0.rar
    echo $this->Html->link($title, $filename,array('escape' => false)); 
?>

function download($id = null) {
    $download = $this->Download->findById($id);
    $this->set(compact('download'));
    if(!empty($id)) {
        // increment the number of items downloads 
        $this->Download->save(array(
            'Download' => array(
                'id' => $id,
                'counts' => ($download['Download']['counts'] + 1)
            )
        ));
    }

    header('Location: http://localhost/tet/files/'.$download['Download']['filename']);
    exit();
}

not this way i am afraid.

you either need to redirect from an action (which counts before redirecting) or use Media view to pass it through. thats how I do it. In the action you can then raise the count prior to sending the file.

There are lots of techniques, though in the simplest way, you can use a text file to do this.

Create a txt file and write 0 (zero) into it.

In your index function, read the content of your file.

$counter = file_read_contents('counter.txt');

Increase the read value by 1.

$counter++;

Write new value into file again.

file_put_contents('counter.txt', $counter);

So, it counts downloads and keep number in that file.

If you want to count downloads, you should create a function that serves those downloads and create a field in your database that increments downloads each time this function is called.. For example

Call the following function from your view passing the $filename and the $id

To try out at first use, taking ID=4 as one of the downloads ID in your DB

http://www.yourdomain.com/downloads/download/4

And Then your controller would be...

Class DownloadsController extends AppController{
    // All your other functions here

    function download($id = null){

        $this->Article->updateAll(
            array('Download.count' => 'Download.count+1'),
            array('Download.id' => $id)
        );

        $download = $this->Download->findById($id);

        $this->set('filename', $download['Download']['filename']);

        //$filename is an array that can then be used in your view to pass the file for download. to find out what is has you can use debug($filename) in your view
        }
}

Then you need to create a special layout so the browser knows that the request file is a download and you will also need to create a view for download.ctp. Basically when you click the file link on your page, it will call this function which will use its view to serve the file.

You can access the following which will provide some insight on what needs to be done..
