laravel5.1 validate number

How to validate numbers using laravel validator. In my case I need to validate if a number is between "1.00" and "50.00".

As seperator between the number pairs the "." and the "," should be allowed. The number should have only two decimal places. Is there a way to get this done using standart laravel validators combined?

using a regex, the regex should match these requirements:

starting with 0-9 (2 numbers are possible)

followed by one . or one ,

followed with 0-9 (2 numbers are possible)

OR simple numbers like 1-9 with NO dots and NO commas

numbers between 1 and 50 should be allowed in total. This regex should be used for a prepaid system where users should be able to topup their accounts from 1 to 50. For this reason entries like 1.00 and 1,00 should be valid as well as 1 or 2. 50.00 is the maximum of amount. 1.00 the minimum.

This is the regex you are lookig for:

/^((([1-4][0-9]|[1-9])([,.]\d{1,2})?)|(?:50([,.]0{1,2})?))$/

You can use regular expresions like this:

   $rules = [
       'field' => 'regex:/^\d*(\.\d{2})?$/'
   ];

I would create the following Request class:

<?php

namespace App\Http\Requests;

class TestRequest extends Request
{
    public function rules()
    {
        return [
            'number' => [
                'required',
                'regex:/^\d{1,2}(\.\d{1,2})?$/',
                'numeric',
                'min:1',
                'max:50'
            ],
        ];
    }

    public function authorize() {
        return true;
    }

    public function all() {
        $data = parent::all();
        if (isset($data['number'])) {
            $data['number'] = str_replace(',','.', $data['number']);
        }

        return $data;
    }
}

and in Controller inject this Request class:

public function test(TestRequest $request)
{
      dd($request->all());    
}
