Laravel 4 file upload error

Question

I have an file upload form, and I want to use validator.

$roles = array(
    'title' => 'required|max:128',
    'description' => 'required|max:2800',
    'picture' => 'mimes:jpeg,bmp,png'
);

My problem is, if I try to upload a picture, I get this error: finfo::finfo(): Failed to load magic database at '' . The $_SERVER['MAGIC'] is set to /usr/share/misc/magic ... So I don't know why throw this error. But if I comment out the picture validation line, and I select a photo is the form, I also get an error: Serialization of 'Symfony\\Component\\HttpFoundation\\File\\UploadedFile' is not allowed .
Can anybody tell me what should I do?

UPDATE

$finfo = new finfo(FILEINFO_MIME_TYPE);
$filename = public_path() . '/images/test.png';
var_dump($finfo->file($filename));

It works good string(9) "image/png" . But in the validation still bad.

Answer 1

Laravel uses finfo for file validation and finfo needs magic_file name of a magic database file, usually something like /path/to/magic.mime. In your php.ini make sure you have something like this available and it points qo the right resource

[mime_magic]
mime_magic.magicfile = "D:\xampp\php\extras\magic.mime"

This is the path for the file in my xampp installation. It may varies depending on your OS and If not specified, the MAGIC environment variable is used, for more information, visit fileinfo . Also, this may help you. It's not related to Laravel but your php installation.
