Laravel old() not working
提问by BOTJr.
{!! Form::open(array('route' => 'posts.store', 'data-parsley-validate' => '')) !!}
{{ Form::label('title', 'Title:') }}
{{ Form::text('title',old('title'), array('class' => 'form-control', 'required' => '', 'maxlength' => '255')) }}
{{ Form::label('slug', 'Slug:') }}
{{ Form::text('slug',old('slug'), array('class' => 'form-control', 'required' => '', 'minlength' => '5', 'maxlength' => '255') ) }}
{{ Form::label('category_id', 'Category:') }}
<select class="form-control" name="category_id">
@foreach($categories as $key=>$value)
<option value='{{ $key }}'>{{ $value }}</option>
@endforeach
</select>
{{ Form::label('tags', 'Tags:') }}
<select class="form-control select2-multi" name="tags[]" multiple="multiple">
@foreach($tags as $tag)
<option value='{{ $tag->id }}'>{{ $tag->name }}</option>
@endforeach
</select>
{{ Form::label('body', "Post Body:") }}
{{ Form::textarea('body',old('body'), array('class' => 'form-control','id'=>'editor1')) }}
{{ Form::submit('Create Post', array('class' => 'btn btn-success btn-lg btn-block', 'style' => 'margin-top: 20px;')) }}
{!! Form::close() !!}
This is my form for something but however when i submit it and validate it on the server side and redirect to the same page , it doesn't display the old values.
这是我的表单，但是当我提交它并在服务器端验证它并重定向到同一页面时，它不会显示旧值。
Controller side
控制器端
$this->validate($request,[
'title'=>'required|max:255',
'body'=>'required',
'slug'=>'required|max:255|alpha_dash|min:5|unique:posts,slug',
'category_id'=>'required|integer'
]);
$post=new Post;
$post->title=$request->title;
$post->slug=$request->slug;
$post->body=$request->body;
$dom = new Dom;
$dom->load($request->body);
$img = $dom->find('img')[0];
if(is_null($img))
return redirect()->back()->withErrors('Add atleast one image in the post.');
What would be the solution of the problem?
问题的解决方案是什么？

Use ->withInput()to go back with data
用于->withInput()返回数据
return redirect()->back()->withInput()->withErrors('Add atleast one image in the post.');
