Example of Yii implementation of article list top function

The example in this article describes how Yii implements the top function of the article list. Share it with everyone for your reference, the details are as follows:

My understanding: First click to get the current ID, the model layer queries all sort fields, traverses the data, gets the maximum value, modifies the data, and replaces the data.

Rendering:

Model layer:

//显示列表
public function lists1()
{
    $arr=Yii::$app->db->createCommand("select * from acticle join type on type.t_id=acticle.t_id order by sort desc")->queryall();
    return $arr;
}
//置顶
public function top(){
    $arr=$this::find()->select("sort")->asArray()->all();
    //print_r($arr);die;
    $rows=array();
    foreach($arr as $key=>$v)
    {
      $rows[]=$v['sort'];
    }
    $max=array_search(max($rows),$rows);
    return intval($rows[$max]+1);
  }
  //修改数据
  public function update1($sort,$acticle_id){
    $arr=Yii::$app->db->createCommand()->update("acticle",['sort'=>$sort],['acticle_id'=>$acticle_id]);
    if($arr->execute()){
      return 1;
    }else{
      return 2;
    }
}

Controller:

//文章置顶
public function actionTopq(){
    $acticle_id=$_GET['id'];
    //echo $acticle_id;die;
    //获取最大sort
    $model=new Acticle();
    $sort=$model->top();
    //修改数据
    $row=$model->update1($sort,$acticle_id);
    //echo $row;die;
    if($row==1){
      //替换数据，置顶
      $res1=$model->lists1();
      $art=new Articles();
      $res6=$art->get_right($res1,5);
      return $res6;
    }else{
    return false;
    }
}

View layer:

<!-- 文章列表 -->
<div class="r_230_b ma_b8" style="float:right;right:0;line">
<div class="news_t" ><h2 id="font-nbsp-color-d-c-最新动态-font"><font color="#d52c99">最新动态</font></h2></div>
<?php echo $res6;?>
</div>
<script>
function topq(ts){
  $.get("index.php?r=index/topq",{id:ts},function(msg){
    $(&#39;#sort&#39;).html(msg);
    //alert(msg);
  })
}
</script>

I hope that what this article describes will be helpful to everyone based on the Yii framework. PHP programming helps. Thanks for supporting PHP Chinese website.
