带有 csrf token 的表单 View

<div class="col-md-8 col-md-offset-2">

Controller

首先验证请求，然后为用户创建新电子邮件(如果他没有)，然后与用户一起保存帖子

public function storePostAds(Request $request)
    {
        $this->validate($request, [
           'title' => 'required',
           'description' => 'required',
           'image' => 'required',
           'category_id' => 'required',
           'subcategory_id' => 'required',
        ]);
        $email = $request['email'];
        $title = $request['title'];
        $description = $request['description'];
        $category = $request['category_id'];
        $subcategory = $request['subcategory_id'];
        $image = $request->file('image');
        $user = User::where('email', $email)->first();
        if(!$user){
            $user = new User();
            $user->email = $email;
            $user->save();
        }
        if($image->isValid()){
            $name = $image->getClientOriginalName();
            $key = 'images/'.$name;
            Storage::disk('s3')->put($key, file_get_contents($image));
        }
        $post = new Post();
        $post->title = $title;
        $post->description = $description;
        $post->category_id = $category;
        $post->subcategory_id = $subcategory;
        $post->image = $image;
        $user->posts()->save($post);
        return redirect('/');
    }

Ajax

ajax 在选择后获取每个类别的子类别

(function($){
    $('#category').on('change', function(e){

        var cat_id = e.target.value;
        $.get('/ajax-subcategory?cat_id=' + cat_id, function(data){
            var subcategory = $('#subcategory');
            subcategory.empty();
            $.each(data, function(index, subcatObj){
               subcategory.append('<option value="'+subcatObj.id+'">'+subcatObj.name+'</option>');
            });
        });
    });
}(jQuery));

Answer 1

您的类别和子类别字段的名称是“category”和“subcategory”，但在您的 Controller 代码中分别称为“category_id”和“subcategory_id”。
