Laravel Optional Field Validation Example Tutorial

Hello Artisan,

In this tutorial, I will share with you that how we can validate optional fields in Laravel application. Sometimes we need to validate optional fields. Assume you have a field and it is optional.

Now you want to validate it if the user gives this with form data. How we can validate this optional column? We will often need to mark your "optional" request fields as nullable if we do not want the validator to consider null values as invalid.

For example:

$request->validate([
    'title' => 'required|unique:posts|max:255',
    'body' => 'required',
    'publish_at' => 'nullable|date',
]);

In this above example, I am specifying that the publish_at field may be either null or a valid date representation. If the nullable modifier is not added to the rule definition, the validator would consider null an invalid date.
