[laravel] blog project practical notes - references to pop-up external plug-ins and addition and editing of background article categories, etc.

This is a practical blog project done in a Windows environment. In the last article, we implemented Ajax asynchronous modification, but the pop-up window was too ugly. This article will give you a brief introduction to the reference of the pop-up window. Then let’s introduce the creation of background article classification. I hope to be helpful.

1. Reference to external pop-up windows

Introduce a pop-up window library:

http://layer.layui.com/

1) Download:

2) Then drag the file in the compressed package to the path of step 3)

3) In the path of the picture below,

4) Then quote

<script src="{{URL::asset(&#39;/layer/layer.js&#39;)}}"></script>

5) What to do next Use

function onchangeOrder(obj,cate_id){
var cate_order=$(obj).val();
$.post(
"{{url('home/cate/changeorder')}}",
{'_token':'{{csrf_token()}}','cate_id':cate_id,'cate_order':cate_order},
function(data){
//alert(data.msg);
layer.msg(data.msg, {icon: 6});
});
}

6) After successfully updating the icon

function onchangeOrder(obj,cate_id){
var cate_order=$(obj).val();
$.post(
"{{url('home/cate/changeorder')}}",
{'_token':'{{csrf_token()}}','cate_id':cate_id,'cate_order':cate_order},
function(data){
//alert(data.msg);
//layer.msg(data.msg, {icon: 6});
if(data.status==0){
layer.msg(data.msg, {icon: 6});
}else{
layer.msg(data.msg, {icon: 5});
}
});
}

the page is completed, and the real sorting

public function Tree(){
//$categroy = $this->all();                                                 //这个是去所有数据
$categroy = $this->orderby('cate_order','asc')->get(); //改成只取一条
return $this->getTree($categroy);
}

2. Add template allocation to the background article category and embed the parent category

Display page view:

<form action="{{url(&#39;home/category&#39;)}}" method="post" autocomplete="off">//向后台提交的数据， action="{url(&#39;home/category&#39;)}"申请的路由
<select name="cate_pid">    //下拉选择框
<option value="">=请选择=</option>
<option value="19">精品界面</option>
<option value="20">推荐界面</option>
</select>
<input type="text" name="cate_name">  输入框
<textarea name="cate_keywods"></textarea>  文本框
<button class="btn btn-primary" type="submit" name="submit">添加新栏目</button>
</form>

Static reading:

<select name="cate_pid">
<option value="0">=顶级分类=</option>
<option value="19">精品界面</option>
<option value="20">推荐界面</option>
</select>

Dynamic reading:

<select name="cate_pid">
<option value="">=顶级分类=</option>
@foreach($data as $d)
<option value="{{$d->cata_id}}">{{$d->cata_name}}</option>
@endforeach
</select>

Controller:

controller
//GET home/category/create 添加分类
public function create(){
$data = CategroyModel::where('cate_pid',0)->get();
return view('home/categroy/add',compact('data'));
}
// POST home/category      填加分类提交
public function store(){
$input=Input::all();  //获取前端的所有提交的数据
dd($input);
}

3. Backend article classification, add data Validation verification and storage

view error message prompt:

@if(count((array)$errors)>0)
@if(is_object($errors))
@foreach($errors->all() as $error)
{{$error}}
@endforeach
@else
{{$errors}}
@endif
@endif
controller:
// POST home/category      填加分类提交
public function store(){
//除了token值，其余都要存进数据库，用except排出放将token排除，全部用all
$input=Input::except('_token');
$rules = [
'cate_name'=>'required'
];
$message = [
'cate_name.required'=>'分类名称不能为空!',
];
$validator= Validator::make($input,$rules,$message);
if($validator->passes()){
// 用create将数据都存进数据库
$res = CategroyModel::create($input);
//如果添加成功后返回列表页面
if($res){
return redirect('home/category');//成功返回列表页面
}else{
return back()->with('errors','数据填充失败!');
}
}else{
//dd($validator->errors()->all());
return back()->withErrors($validator);
}
// dd($input);
}
model :
protected $guarded =[];//不可编辑字段包含哪些 $fillable $guarded属性

4. Background article classification editing and simulation put method

Page display view:

<form action="{{url(&#39;home/category/&#39;.$res->cate_id)}}" method="post" autocomplete="off">
     <input type="hidden" name="_method" value="put">   //修改传参方法
  {{csrf_field()}}   //csrf认证
<div class="col-md-5">
<h1 id="编辑分类">编辑分类</h1>
  @if(count((array)$errors)>0)      //报错信息提示
              @if(is_object($errors))
                 @foreach($errors->all() as $error)
                    {{$error}}
                 @endforeach
              @else
                 {{$errors}}
              @endif
           @endif
<div class="form-group">
<label for="category-fname">父级分类</label>
<select id="category-fname" class="form-control" name="cate_pid">
<option value="0" selected>=顶级分类=</option>
@foreach($data as $d)
<option value="{{$d->cate_id}}"
  @if($d->cate_id==$res->cate_pid) selected @endif     //判断是否是顶级分类
>{{$d->cate_name}}</option>
@endforeach
</select>
</div>
<div class="form-group">
<label for="category-name">分类名称</label>
<input type="text" id="category-name" name="cate_name" value="{{$res->cate_name}}"  class="form-control" placeholder="在此处输入栏目名称"  autocomplete="off">
</div>
<div class="form-group">
<label for="category-alias">分类标题</label>
<input type="text" id="category-alias" name="cate_title" value="{{$res->cate_title}}"  class="form-control" placeholder="在此处输入栏目别名"  autocomplete="off">
</div>
<div class="form-group">
<label for="category-keywords">关键字</label>
<input type="text" id="category-keywords" name="cate_keyword" value="{{$res->cate_keyword}}"   class="form-control" placeholder="在此处输入栏目关键字" autocomplete="off">
</div>
<!--             <div class="form-group"> -->
<!--               <label for="category-describe">描述</label> -->
<!--               <textarea class="form-control" id="cate_describe" name="cate_describe" {{$res->cate_describe}} rows="4" autocomplete="off"></textarea> -->
<!--             </div> -->
<div class="form-group">
<label for="category-keywords">排序</label>
<input type="text" id="category-keywords" name="cate_order" value="{{$res->cate_order}}"  class="form-control" placeholder="在此处输入栏目关键字" autocomplete="off">
</div>
<button class="btn btn-primary" type="submit" >提交</button>
</div>
</form>

value: refers to the default value

Controller controller:

// GET home/category/{category}/edit 编辑分类
//接受前端传过来的参数
public function edit($cate_id){
//查询当前这条的数据
$res = CategroyModel::find($cate_id);
//data数据是读取所有cate_pid等于0的顶级分类
$data = CategroyModel::where('cate_pid',0)->get();
//把本来的数据分配到页面当中然后再做修改
return view('home.categroy.edit',compact('res','data'));
}
// PUT home/category/{category}   更新分类
//这个参数通过get方法传过来的参数
public function update($cate_id){
//剔除不要的参数
$input=Input::except('_method','_token');
//update更新cate_id等于2的这条数据
$res = CategroyModel::where('cate_id',$cate_id)->update($input);
//如果添加成功后返回列表页面
if($res){
//如果成功跳转到列表页面
return redirect('home/category');
}else{
return back()->with('errors','数据填充失败!');
}
}
