Laravel 5.2 Eloquent多重选择preg_replace（）：参数不匹配，模式是字符串，而替换是数组

标签： php laravel model eloquent

我已经看到了这个问题的多个不同答案，其中没有一个能够继续使用表单模型绑定。似乎表单将标记提交为数组，实际上应该是一个字符串。有什么想法吗？

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');
}

这是我的追踪：

答案非常简单，因为我们之前的团队将标签作为表格列＆gt;而在“新闻”雄辩模型中设置了标签字段。＆gt; 。一旦我将其删除，现在全部修好了！
