ckeditor可以更新数据库内容吗？(can ckeditor update database content?)

 你能给我一种方法将ckeditor的内容保存到数据库吗？  
 我有0％的想法，如何使事情工作，这将是第一次使用一个。 我在谷歌搜索但它总是显示fckeditor（他们是一样的吗？）。 另外，我已经尝试了一些带有AJAX的代码，但仍然无法使其工作，因为它需要一些插件，我实际上并不理解它。  
 无论如何，我使用4.0版本的ckeditor，更喜欢PHP或javascript代码，因为我真的不知道AJAX。 这是我的试用代码：

 非常感谢您的时间和帮助。 

can you give me a way to save the contents of the ckeditor to the database? 
i have 0% idea on how to make things work for this would be the first time to be use one. i've searched on google but it always shows the fckeditor(are they the same?). also, i've tried some codes with AJAX on it but still couldn't make it work because it requires some plugin and i don't actually understand it. 
anyway, i'am using the 4.0 version of ckeditor and would prefer php or javascript code because i don't really know AJAX. here's my trial code:

 没有  
 
  TimeStamps stamps = realm.where（TimeStamps.class）.findFirst（）;  
 
 这会在当前线程上获得stamps  
 
  if（！timeStamps.getInfractionTimeStamps（）。equalsIgnoreCase（ stamps.getInfractionTimeStamps（） ））  
 
 这会尝试访问不同线程上的stamps实例，因此您将收到IllegalStateException  
 
  返回null;  
 
 即使它确实起作用，这条线也会使RxJava2抛出一个NullPointerException异常  
 
  .subscribeOn（Schedulers.newThread（））  
 
 这可以很容易地被Schedulers.io()代替，所以它不会创建太多的线程（尽管当然你应该确保使用try(Realm realm = ...)或者finally { realm.close() } ）  
 
  .subscribe（new Observer>（）{  
 
 这是错误的，除非你“正确地实现了onSubscribe”，这是不应该的，这应该是new DisposableObserver<List<Infraction>>() 。  
 在这种情况下，您的Retrofit界面应该可能会公开Single<T> ，因为完成后单身会自动取消订阅。  
 
Single<TimeStamps> callTimeStamp = apiInterface.getTimeStamp();

   callTimeStamp.flatMap((timeStamps) -> {
        try(Realm realm = Realm.getDefaultInstance()) {
            TimeStamps stamps = realm.where(TimeStamps.class).findFirst();
            if(!timeStamps.getInfractionTimeStamps().equalsIgnoreCase( stamps.getInfractionTimeStamps()))
                return apiInterface.getInfractions();
            else
                return Single.never();
       }
   }).subscribeOn(Schedulers.io())
     .observeOn(AndroidSchedulers.mainThread())
     .subscribe(new DisposableObserver<List<Infraction>>() {
       @Override
       public void onNext(List<Infraction> infractions) {

       }

       @Override
       public void onError(Throwable e) {

       }

       @Override
       public void onComplete() {

       }
   });

No 
 
 TimeStamps stamps = realm.where(TimeStamps.class).findFirst(); 
 
This obtains stamps on the current thread 
 
 if(!timeStamps.getInfractionTimeStamps().equalsIgnoreCase( stamps.getInfractionTimeStamps())) 
 
This attempts to access that stamps instance on a different thread, so you'll get an IllegalStateException 
 
 return null; 
 
Even if it did work, this line would make RxJava2 throw a NullPointerException 
 
 .subscribeOn(Schedulers.newThread()) 
 
This could easily be Schedulers.io() instead so that it wouldn't create too many threads (although then of course you should make sure you use try(Realm realm = ...) or finally { realm.close() }) 
 
 .subscribe(new Observer>() { 
 
This is wrong unless you "properly implement onSubscribe" which is not expected at all, this should be new DisposableObserver<List<Infraction>>(). 
In which case your Retrofit interface should probably expose Single<T>, as singles automatically unsubscribe when done. 
 
Single<TimeStamps> callTimeStamp = apiInterface.getTimeStamp();

   callTimeStamp.flatMap((timeStamps) -> {
        try(Realm realm = Realm.getDefaultInstance()) {
            TimeStamps stamps = realm.where(TimeStamps.class).findFirst();
            if(!timeStamps.getInfractionTimeStamps().equalsIgnoreCase( stamps.getInfractionTimeStamps()))
                return apiInterface.getInfractions();
            else
                return Single.never();
       }
   }).subscribeOn(Schedulers.io())
     .observeOn(AndroidSchedulers.mainThread())
     .subscribe(new DisposableObserver<List<Infraction>>() {
       @Override
       public void onNext(List<Infraction> infractions) {

       }

       @Override
       public void onError(Throwable e) {

       }

       @Override
       public void onComplete() {

       }
   });
