Laravel required_if validation

Question

I want to validate the cost field. If the activity_code value is other than "SE". It can be any value but not SE.

$rules = [
'cost' => 'required_if:activity_code,null',
'select_plans' => 'required_if:activity_code,SE',
];

Answer 1

$rules = [
'cost' => 'required_unless:prf_activity_code,!=,SE',
'select_plans' => 'required_if:activity_code,SE',
];

Answer 2

You can use:

$rules = [
'cost' => 'required_unless:activity_code,SE',
'select_plans' => 'required_if:activity_code,SE',
];

or

$rules = [
'cost' => 'required_if:activity_code,!=,SE',
'select_plans' => 'required_if:activity_code,SE',
];
