How to change filename in file upload using Web::instance()?

[Michael Miquel]

How to change filename in file upload using Web::instance()? $file['name'] = "newfilename"; doesn't work.

$f3->set('UPLOADS','uploads/'); // don't forget to set an Upload directory, and make it writable!

$overwrite = false; // set to true, to overwrite an existing file; Default: false
$slug = true; // rename file to filesystem-friendly version

$files = $web->receive(function($file){
        var_dump($file);
        /* looks like:
          array(5) {
              ["name"] =>     string(19) "csshat_quittung.png"
              ["type"] =>     string(9) "image/png"
              ["tmp_name"] => string(14) "/tmp/php2YS85Q"
              ["error"] =>    int(0)
              ["size"] =>     int(172245)
            }
        */
        // $file['name'] already contains the slugged name now

        // maybe you want to check the file size
        if($file['size'] > (2 * 1024 * 1024)) // if bigger than 2 MB
            return false; // this file is not valid, return false will skip moving it

        // everything went fine, hurray!
        return true; // allows the file to be moved from php tmp dir to your defined upload dir
    },
    $overwrite,
    $slug
);

I got an error:

Parameter 1 to {closure}() expected to be a reference, value given

code:

$files = $web->receive(function(&$file){
[...]
$file['name'] = "newfilename";

(PHP 5.3)

Since we can't work around PHP's call_user_func* limitation on passing arguments by reference, the dev branch code now allows you to specify a user-defined function in place of $slug, so you can name the file whatever you want.

[J Francisco Herrera Roldán]

So, how I can retrieve a var in the slug scope, like the extension of the file or the type of the file.
$web->receive(function($file){
            var_dump($file); //I can see this
            $_SESSION['tmp_name']=$file['name'];
           
            if($file['size'] > (4 * 1024 * 1024)) // if bigger than 2 MB
                return false;
            },
                true, // overwrite
                function(){
                    list($txt, $ext) = explode(".", $file['name']);
                    return time().$ext;}
            );
