aravel 8 now has three validation rules for prohibited fields, including prohibited_if, prohibited_unless, and prohibited. Let’s walk through a few examples of where the prohibited* validation rules might be useful, and look at each one in more detail.

Prohibited If and Unless

Jess Archer contributed the prohibited if/unless validation rules released in Laravel  Laravel 8.32. The basic idea of “prohibited” validation rules is that a given field should be prohibited from having data if another field is present or if a field should be allowed in a request at all.

Here’s the example Jess provided in the  pull request for this feature, which illustrates perfectly how to use this rule to explicitly prevent contradictory input:

Validator::validate([
    'is_deceased' => false, 
    'date_of_death' => '2021-03-09'
], [
    'date_of_death' => 'prohibited_unless:is_deceased,true'
]);
