<"htmlcode">

public function rules()
{
  return [
    [['branch_id'], 'integer'],
    [['branch_name', 'branch_address', 'branch_created_date', 'branch_status','companies_company_id'], 'safe'],
  ];
}




修改search方法：


public function search($params)
{
  $query = Branches::find();
  $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;
  }
  // 添加下面这行代码
  $query->joinWith('companiesCompany');
  $query->andFilterWhere([
    'branch_id' => $this->branch_id,
  //  'companies_company_id' => $this->companies_company_id,
    'branch_created_date' => $this->branch_created_date,
  ]);
  $query->andFilterWhere(['like', 'branch_name', $this->branch_name])
    ->andFilterWhere(['like', 'branch_address', $this->branch_address])
    ->andFilterWhere(['like', 'branch_status', $this->branch_status])
     // 添加下面这行代码
    ->andFilterWhere(['like', 'companies.company_name', $this->companies_company_id]);
  return $dataProvider;
