How can I implement conditional validation in Laravel?

In Laravel, you can use the sometimes method to apply conditional validation rules. For example, if you want to validate a field only if another field has a certain value, you can do it like this.

Can you show me an example of that?

Sure! Here's an example:

$request->validate([
    'email' => 'required|email',
    'subscription' => 'required_if:email_verified,1',
]);

In this case, the 'subscription' field is required only if 'email_verified' is 1.

What if I want to validate multiple fields conditionally?

You can chain multiple rules using the sometimes method. For instance:

$request->validate([
    'field1' => 'required',
    'field2' => 'required_if:field1,value',
    'field3' => 'required_if:field1,value',
]);

This will require 'field2' and 'field3' only if 'field1' has a specific value.
