Laravel – How to check decimal values from 0 till 100?

On laravel 11 site I need to check decimal values from 0 till 100(with 2 decimals possible) and I do it with rules :

['required', 'numeric', 'between:0,100'],

OR

required|numeric|min:0.01|max:100

but both not works. Which rules are valid ?

"laravel/framework": "^11.9",

Thanks in advance!

    [
    'required',
    'numeric',
    'regex:/^d{1,2}(.d{1,2})?$|^100(.00?)?$/',
    'between:0,100',
]

    • regex:/^d{1,2}(.d{1,2})?$|^100(.00?)?$/: This regular expression allows numbers from 0 to 100, with up to two decimal places.

      • ^d{1,2}(.d{1,2})?$: Matches numbers from 0 to 99.99.
      • |^100(.00?)?$: Allows the number 100, optionally followed by .0 or .00.

    • between:0,100: Ensures that the number is within the range 0 to 100.

    You can use this, too

    $request->validate([
    'your_field_name' => [
        'required',
        'numeric',
        'between:0,100',
        'regex:/^d{1,2}(.d{1,2})?$/'
    ],
], [
    'your_field_name.regex' => 'The :attribute must be a number with up to two decimal places.',
]);

    You can do this using regex way

    $request->validate([
'field_name' => [
    'required',
    'numeric',
    'between:0,100',
    'regex:/^d*(.d{1,2})?$/',
    ],
 ]);

    If you need this without using regex, you can follow the steps below

    Create Custom Validation Rule

    php artisan make:rule DecimalPrecision

    Implement Rule Logic

    namespace AppRules;

use IlluminateContractsValidationRule;

class DecimalPrecision implements Rule
{
    public function passes($attribute, $value)
    {
        return is_numeric($value) && $value >= 0 && $value <= 100 && preg_match('/^d+(.d{1,2})?$/', $value);
    }

    public function message()
    {
        return 'The :attribute must be a number between 0 and 100 with up to 2 decimal places.';
    }
}

    Use Custom Rule

    use AppRulesDecimalPrecision;

$request->validate([
    'value' => ['required', 'numeric', new DecimalPrecision()],
]);
