How to make alpha_dash field optional in laravel?

Question

Laravel

Validates old and new password:

'old_password' => 'max:255|required_with:new_password|old_password',
'new_password' => 'max:255|required_with:old_password|min:6|alpha_dash',

If the user did not enter the old and new password, then the validation should pass without errors.
But the empty field New password produces validation errors on min:6 and alpha_dash
How can I get rid of these errors?

Answer 1

You can add nullable. If the field is empty, then the rest of the validation will not pass.

'new_password' => 'nullable|max:255|required_with:old_password|min:6|alpha_dash'
