Question

我有一个可用性日历，我正在尝试使用Laravel发布到我的数据库。当我转出我的POST时，我得到了这个......

string(1440) "s:1430:"2012-11-06;;1;;888,2012-11-07;;1;;888,2012-11-08;;

可能导致此错误的原因，以及为什么它包含在我的数据库POST中？下面是我的控制器代码。一切都很好，就像这样。我能够将该字符串发布到数据库（我使用serialize（）将其转换为数组中的字符串）我也可以从数据库中获取它并且它在前端显示就好了。这些错误似乎没有什么区别，但我觉得我做的事情有些不对。

public function post_availability_save()
  {
$availability = serialize(Input::get('dop_booking_calendar'));
//var_dump($availability);die;

$id = Auth::user()->id;

Availability::update($id, array(
  'user_id' => Auth::user()->id,
  'availability' => $availability
  ));
return Redirect::to('admin');
}

  public function get_availability_load()
  {
$id = Auth::user()->id;

$availability = array(
  'availability' => Availability::find($id)->availability
);

var_dump($availability);

}

修改更多地了解它，它也倾销了我的html布局的开头...... 谁知道是什么原因导致的？我会深入挖掘一下。编辑 11/13/12

Answer 1

return Redirect::to('admin');

发送标题＆＃39;在$ title中或在布局中设置它就像在action_index（）

中一样

return Redirect::to('admin')->with('title','supercooltitle');

或

return Redirect::to('admin')->with_title('supercooltitle');

然后你的视图可以获取$ title并退出显示未定义的引用。

其他选项是在布局上设置它类似于您对索引所做的操作。

Answer 2

好的。所以，我终于明白了。错误是在帖子中发送的，因为我是var_dump'ing我们被选中的结果。我通过'die'和'json_encode'修复它。感谢所有帮助过的人！

为什么在我的POST中呈现这个html错误？
