File Upload and allowed type

[eluser]satie[/eluser]
No, for me doesn't work.

I resolve creating a function (in /application/library/) that controls extentions AFTER uploading.
and if returns FALSE delete the file.

Code:

// example $nome_immagine = "ciccio.jpg" AND $estensioni = "jpg|gif"
    public function controlla_estensione($nome_immagine, $estensioni)
    {
        $ext = explode("|", $estensioni);
        $ext_file = explode(".", $nome_immagine);
        $real_ext_file = end($ext_file);
        
        if( in_array($real_ext_file, $ext))
        {
            return TRUE;
        }else{
            unlink($_SERVER['DOCUMENT_ROOT'].'/affido/assets/public/images/'.$nome_immagine);
            return FALSE;
        }
    }

Thanks for your interest. I appreciated.
