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><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){
$('#sort').html(msg);
//alert(msg);
})
}
</script>
