Question

大家好我想在视图文件中使用$ searchModel搜索数据，并且在显示和搜索相关表时遇到问题。

以下是我的clubname，其中organiser是来自Event表格的相关数据，我正在尝试以public function rules() { return [ [['title', 'description', 'location', 'clubname'], 'safe'], ]; } public function search($params) { $query = Event::find(); $dataProvider = new ActiveDataProvider([ 'query' => $query, ]); $this->load($params); $query->joinWith(['organiser']); if (!$this->validate()) { // uncomment the following line if you do not want to return any records when validation fails // $query->where('0=1'); return $dataProvider; } $query->andFilterWhere([ 'id' => $this->id, 'interest_id' => $this->interest_id, ]); $query->andFilterWhere(['like', 'title', $this->title]) ->andFilterWhere(['like', 'description', $this->description]) ->andFilterWhere(['like', 'location', $this->location]); $query->andFilterWhere(['like', 'organiser.clubname', $this->organiser_id]); return $dataProvider; }形式进行搜索。

$search

这是我的<?php $form = ActiveForm::begin([ 'action' => ['index'], 'method' => 'get', ]); ?> <div class="row"> <?= $form->field($searchModel, 'title',[ 'template' => ' <div class="col-lg-2 col-md-2 col-sm-2 col-xs-3">{label}</div><div class="col-lg-4 col-md-4 col-sm-6 col-xs-8">{input}</div>' ])->textInput(['maxlength' => true]) ?> <?= $form->field($searchModel, 'clubname',[ 'template' => ' <div class="col-lg-2 col-md-2 col-sm-2 col-xs-3">{label}</div><div class="col-lg-4 col-md-4 col-sm-6 col-xs-8">{input}</div>' ])->textInput(['maxlength' => true]) ?> </div> <div class="form-group"> <?= Html::submitButton('Search', ['class' => 'btn btn-primary btn-xs']) ?> <?= Html::resetButton('Reset', ['class' => 'btn btn-default btn-xs']) ?> </div> <?php ActiveForm::end(); ?>页面及其下方的列表

搜索clubname时没有问题，但我希望用户也可以使用Organiser搜索id表中的字段，并且它们与{{1}有关系}。

您需要在RelationName.property中添加searchModel：

public function rules()
{

return [
    [['title', 'description', 'location', 'organiser.clubname'], 'safe'],
];

}

然后添加attributes()功能：

public function attributes() 
{ 
  return array_merge(parent::attributes(), 
  [ 
    'organiser.clubname', 
  ]
  );
}

最后将查询添加到搜索数据中：

$query->andWhere(['Attribute_name' => $params['attribute']]);
