$validator = Validator::make(Input::all(), $rules);
// process the form
if ($validator->fails()) {
return Redirect::to('forms/create')->withErrors($validator);
} else {
// store
$forms = new Forms;

Answer 1

To validate mime type of a file input in Laravel you can use the mimes rule. Remember to match the mime type detected with the actual mime of file you provide. It may vary on different servers.
For example, you want to enable adding and word document in you form:
1) in config/mimes.php add the below mime types:
'doc' => array('application/msword', 'application/vnd.ms-office'),
'docx' => array('application/vnd.openxmlformats-officedocument.wordprocessingml.document', 'application/zip'),
2) in your validation $rules add the following elements:
'file' => 'required|max:10000|mimes:doc,docx' //a required, max 10000kb, doc or docx file

Answer 2

Try this?
'file' => 'required|max:10000|mimes:application/vnd.openxmlformats-officedocument.wordprocessingml.document'
You may want to set some custom message for the response though :)

Answer 3

As of Laravel 9.22 you can write the validation rules a lot shorter and more readable like:
'file' => ['required', File::types(['doc', 'docx'])->smallerThan(10000)]
You can find the available methods in this pr: https://github.com/laravel/framework/pull/43271
