在我的控制器中,我渲染了$dataProvider
$searchModel = new StudentSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index',[
'searchModel' => $searchModel,'dataProvider' => $dataProvider,]);
这是StudentSearch的搜索功能
public function search($params)
{
$query = Student::find();
$query->andFilterWhere([
'student_id' => $this->student_id,'age' => $this->age,]);
$query->andFilterWhere(['like','firstname',$this->firstname]);
$dataProvider = new ActiveDataProvider([
'query' => $query,]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
return $dataProvider;
}
在视图中,我在ListView小部件中使用了$dataprivider,如下所示
<div class="listView">
<?PHP
echo ListView::widget([
'dataProvider' => $dataProvider,'itemView' => '_student_list',]);
?>
</div>
在’_student_list.PHP’中,我列出了学生
我的过滤器
<div class="listFilter"> <input type="text" name="firstname"/> <input type="text" name="age"/> </div>
现在我希望按名字或年龄筛选学生.我怎样才能做到这一点？如果您有任何解决此问题的方法,请提供帮助.谢谢.
1)在您的视图中添加过滤器表单：
<?PHP
use yii\helpers\Html;
use yii\widgets\ActiveForm;
/* @var $form yii\widgets\ActiveForm */
?>
<div class="student-form">
<?PHP $form = ActiveForm::begin(['method' => 'get']); ?>
<?= $form->field($searchModel,'firstname') ?>
<?= $form->field($searchModel,'age') ?>
<div class="form-group">
<?= Html::submitButton('Apply',['class' => 'btn btn-success']) ?>
</div>
<?PHP ActiveForm::end(); ?>
</div>
2)根据收到的GET参数准备StundentSearch模型以返回dataProvider.
必须在规则中指定这些属性才能大规模分配它们.
public function rules()
{
return [
['firstname','string'],['age','integer'],];
}
public function scenarios()
{
// bypass scenarios() implementation in the parent class
return Model::scenarios();
}
public function search($params)
{
$query = Student::find();
$dataProvider = new ActiveDataProvider(['query' => $query]);
if (!($this->load($params) && $this->validate())) {
return $dataProvider;
}
$query->andFilterWhere(['age' => $this->age])
->andFilterWhere(['like',$this->firstname]);
return $dataProvider;
}
