How can I limit the number of files that can be uploaded?

The max validation seems to apply to the size of the image (in kilobytes). How can I make a va

In laravel, there is no built-in validation rule for that. But you can create custom-validation rule to handle this.

Here is a simple custom-validation rule for it.

Create customValidator.php in app/ directory.

Validator::extend('upload_count', function($attribute, $value, $parameters)
{   
    $files = Input::file($parameters[0]);

    return (count($files) <= $parameters[1]) ? true : false;
});

Don't forget to add it to app/start/global.php

require app_path().'/customValidator.php';

In your validation setting,

$messages = array(
    'upload_count' => 'The :attribute field cannot be more than 3.',
);

$validator = Validator::make(
    Input::all(),
    array('file' => array('upload_count:file,3')), // first param is field name and second is max count
    $messages
);

if ($validator->fails()) {
     // show validation error
}

Hope it will be useful for you.
