如果字段1填充，则Laravel验证字段2应为空

Question

How can I validate if field end_date is filled, field start_time should be empty? something like: 'start_time' => 'empty_with:end_date'

public function rules()
{
    return [
        'start_date'    => 'required',
        'end_date'      => 'nullable|after:start_date',
        'start_time'    => 'empty_with:end_date',
        'end_time'      => 'required_with:start_time',
    ];
}

Answer 1

Use the required_without validation if you want the start_time to be required when end_date is empty

 'start_time'    => 'required_without:end_date',

The field under validation must be present and not empty only when any of the other specified fields are not present.
