这是因为您正在使用：
我在商店中有不同的情况，我有三个输入（客户名称-公司名称-代理商名称），并且如果[]，则下拉菜单名为（payment_type）>
情况：付款类型为（现金），所需值为客户名称，（公司名称-代理商名称）必须为空
案例：付款类型为（贷方），所需值为公司名称，（客户名称-代理商名称）必须为空
案例：付款类型为（待定），所需值为代理商名称，（客户名称-公司名称）必须为空
我的问题是控制器内的if语句不起作用
这是我的控制器代码：
if ( Input::has('payment_type') == 'cash') { $this->validate($request,[ 'tkt_no'=>'required', 'sector'=>'required', 'airline'=>'required', 'supplier'=>'required', 'fare'=>'required', 'tax'=>'required', 'total_vat'=>'required', 'total_cost'=>'required', 'k7'=>'required', 'comm'=>'required', 'profit'=>'required', 'sale_price'=>'required', 'pax_name'=>'required', 'client'=>'required', 'mob'=>'required', 'amount_arabic'=>'required', 'amount_english'=>'required', 'action_type'=>'required', 'trans_type'=>'required', 'payment_type'=>'required', ]);
