Yii 模型中attributeLabels()函数的作用

下面这个函数的作用：有两点 1、后面的是前面的注释，在rules验证的时候，如果报错，会把此处的后面的内容显示出来
2、hint作用，即表单中用户插入数据时，提示用户该字段该填什么内容

 public function attributeLabels()
    {
        return [
            "cateid" => "分类名称",
            "title"  => "商品名称",
            "descr"  => "商品描述",
            "price"  => "商品价格",
            "ishot"  => "是否热卖",
            "issale" => "是否促销",
            "saleprice" => "促销价格",
            "num"    => "库存",
            "cover"  => "图片封面",
            "pics"   => "商品图片",
            "ison"   => "是否上架",
            "istui"   => "是否推荐",
        ];
    }

View中调用

                                echo $form->field($model, "cateid")->dropDownList($opts, ["id" => "cates"]);
                                echo $form->field($model, "title")->textInput(["class" => "span9"]);
                                echo $form->field($model, "descr")->textarea(["id" => "wysi", "class" => "span9 wysihtml5", "style" => "margin-left:120px"]);
                                echo $form->field($model, "price")->textInput(["class" => "span9"]);
                                echo $form->field($model, "ishot")->radioList([0 => "不热卖", 1 => "热卖"], ["class" => "span8"]);
                                echo $form->field($model, "issale")->radioList(["不促销", "促销"], ["class" => "span8"]);
                                echo $form->field($model, "saleprice")->textInput(["class" => "span9"]);
                                echo $form->field($model, "num")->textInput(["class" => "span9"]);
                                echo $form->field($model, "ison")->radioList(["下架", "上架"], ["class" => "span8"]);
                                echo $form->field($model, "istui")->radioList(["不推荐", "推荐"], ["class" => "span8"]);
                                echo $form->field($model, "cover")->fileInput(["class" => "span9"]);
