Laravel Optional Field Validation Example Tutorial
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.
$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.
Hope it can help you.
