I would like to put a condition in my store function so that if domain_type=1 then payment_proof is null, otherwise we put a value to payment_proof.

public function update(Request $request, $id)
    {
        $request->validate([
            'command_number' => 'required',
            'domain_type' => 'required',
            'payment_proof' => ['nullable', 'required_if:domain_type:2,3']
        ]);

        $form = Form::find($id);
        $form->command_number = $request->command_number;
        $form->domain_type = $request->domain_type;
        $form->payment_proof = $request->payment_proof;
        $form->save();
        return redirect()->route('forms.index')


    return redirect()->route('forms.index')
}
