Question

我想使用Laravel 5.4发布帖子即使选中的项目也会出现所需的错误。

这是我的邮政控制器的商店部分：

public function store(Request $request)
{
    // validate the date
    $this->validate($request, array(
            'title' => 'required|max:255',
            'slug' => 'required|alpha_dash|min:5|max:255|unique:posts,slug',
            'category_id' => 'required|integer',
            'body'  => 'required',
            'tags' => 'sometimes',
            'featured_image' => 'sometimes|image'
        ));

    // store in the database
    $post = new Post;

    $post->title = $request->title;
    $post->slug = $request->slug;
    $post->category_id = $request->category_id;
    $post->body = $request->body;
    $post->tags_id = $request->tags_id;

    //Save featured image
    if($request->hasFile('featured_image')) {
        $image = $request->file('featured_image');
        $filename = time() . '.' . $image->getClientOriginalExtension();
        $location = public_path('uploads/' . $filename);
        Image::make($image)->resize(800, 400)->save($location);

        $post->image = $filename;
    }

    $post->save();

    $post->tags()->sync($request->tags, false);

    Session::flash('success', 'The blog post was successfully save!');

    // redirect to anther page
    return redirect()->route('posts.show', $post->id);
}

这是我的表格：

{!! Form::open(array('route' => 'posts.store', 'data-parsley-validate' => '', 'files' => true)) !!}
                    <div class="col-md-8">

                        </div>
                    </div>

                {!! Form::close() !!}

我不知道问题究竟在哪里，任何想法？

在视图中，输入字段的名称为category。但是在控制器中，您正在检查category_id。

<强>建议：

为什么不为select字段使用 LaravelCollective HTML包？

{!! Form::select(
        'category_id',
        $category_list,
        null,
        ['class' => 'form-control']
   ) !!}

在create函数中的控制器中。

$category_list = Category::lists('id', 'name')->all();

将此变量传递给视图。

选择选项时需要出错
