How to Validate Numeric Input Length Effectively in Laravel 5?

Validating Numeric Input Length in Laravel 5

To specify the expected length of a numeric input in Laravel 5, the initial approach using 'size' validation rule may not suffice. Instead, you can employ the 'digits' rule as follows:

foo.blade.php:

<input type="text" name="national-id" />

FooController.php:

$rules = [
    'national-id' => 'required|digits:10'
];

The 'digits' rule ensures that the provided input contains the specified number of digits. In this case, it verifies that the 'national-id' field contains 10 digits, without requiring an exact match. Additionally, the 'required' rule ensures that the field is not empty before performing the length validation.

By using the 'digits' rule, you can effectively validate the length of numeric inputs in your Laravel 5 applications.
