Laravel 5.2雄辩多重选择preg_replace（）：参数不匹配，模式是字符串，而替换是一个数组

Question

我见过这个问题的多个不同的答案，其中没有一个保持使用表单模型绑定。它看起来像表单提交标签作为一个数组，实际上应该是一个字符串。有任何想法吗？

控制器：

/** 
* Save new news 
* 
* @param Request $request 
* @return mixed 
*/ 
public function store(NewsRequest $request) 
{ 
    // Create News object and save all form data 
    $news = News::create($request->all()); 

// Rename image file and move to public/images 
$image = $request->file('image'); 
$path = "/images/"; 
$ext = $image->getClientOriginalExtension(); 
$name = str_random(12) . $ext; 
$image->move(public_path() . $path, $name); 
$news->image = $path . $name; 

// Save new image path to News object 
$news->save(); 

//associate with sandbox, if not already 
$news->sandboxes()->sync($request->input('sandboxes')); 

//populate news_tag pivot table with chosen tags 
$news->tags()->sync($request->input('tags')); 



return redirect()->action('FP\NewsController@index'); 
} 

这里是我的跟踪：
