我在这里问了一个与这个问题相关的问题：Main Search Form in Yii2

它不是由于Kartik的Select2搜索下拉小部件中的一些复杂性.现在我暂时切换到简单的Yii2搜索字段.

视图

echo $form->field($model,'_id')->textInput(array('placeholder' => 'search'))->label(false);

模型

<?PHP

namespace app\models;

use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use app\models\User;

/**
 * UserSearch represents the model behind the search form about `app\models\User`.
 */
class UserSearch extends User
{
    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [[/*'_id',*/ 'creator_id'],'integer'],[['fname','lname','email','username','user_type'],'safe'],];
    }

    /**
     * @inheritdoc
     */
    public function scenarios()
    {
        // bypass scenarios() implementation in the parent class
        return Model::scenarios();
    }

    /**
     * Creates data provider instance with search query applied
     *
     * @param array $params
     *
     * @return ActiveDataProvider
     */
    public function search($params)
    {
        $session = Yii::$app->session;

        $query = User::find();
        $query->where(['user_type' => 'BizStaff'])->andwhere(['parent' => new \MongoId($session['company_owner'])]);

        $dataProvider = new ActiveDataProvider([
            'query' => $query,]);

        $this->load($params);

        if (!$this->validate()) {
            // uncomment the following line if you do not want to any records when validation fails
            // $query->where('0=1');
            return $dataProvider;
        }

        $query->andFilterWhere([
            '_id' => $this->_id,'creator_id' => $this->creator_id,]);

        $query->andFilterWhere(['like','fname',$this->fname])
            ->andFilterWhere(['like',$this->lname])
            ->andFilterWhere(['like',$this->email])
            ->andFilterWhere(['like',$this->username])
            ->andFilterWhere(['like','user_type',$this->user_type]);

        return $dataProvider;
    }
}

你对我如何实现单一搜索有任何想法吗？这是一种更智能的搜索,因为它可以根据输入的关键字搜索数据库表中的所有内容.

编辑

当我搜索一个关键字,例如’hello’时,它会在输入密钥后给我这个url和错误：

网址：

07001

错误信息：

Bad Request (#400) Missing required parameters: id

救命.
