如何解决"message": "为 foreach() 提供的参数无效"

public function saveHealthianorderData($request)
    {
        
        try {
            $patient_id = empty($request->patient_id) ? config('api.current_user.patient_id') : $request->patient_id;
            $patientDetails = Patient::where('id',$patient_id)->first();
            $total_net_amount = 0;

      
            foreach ($request->test_details as $value)  {
                $total_net_amount += $value['net_amount'];
                
            }
}
}

解决方法

您有很多选项可以将可迭代对象分配给 foreach

if($request->has('test_details') && is_array($request->test_details)) {
    foreach($request->test_details as $somevariable){
    }
}

或第二种解决方案

$testDetails=collect($request->test_details)->toArray();

或者只是简单的 dd($request->test_details) 并查看它是否为数组
