本文實例講述了Yii2實現讓關聯字段支援搜尋功能的方法。分享給大家參考，具體如下：

這裡有兩張表，表結構如下,companies_compay_id 為外鍵

yii2advanced.branches表：

branch_id:int(11)
comches表：

branch_id:int(11)
comches :varchar(100)
branch_address:varchar(255)

branch_created_date:datetime

branch_status:enum('active','inactive')

yii2advanced.com('actives)
)
company_email:varchar(100)
company_address:varchar(255)
logo:varchar(200)
company_start_date:datetime
company_create_date:datetime
pany_statintime

company_create_date:datetime

company_status:enum)'可以用companiesCompany.company_name來取得公司名，但這樣是不支援搜尋的。

想要支持搜索功能，需要在branches的index視圖添加以下代碼：

<?= GridView::widget([
  &#39;dataProvider&#39; => $dataProvider,
  &#39;filterModel&#39; => $searchModel,
  &#39;columns&#39; => [
    [&#39;class&#39; => &#39;yii\grid\SerialColumn&#39;],
    //添加的代码开始
    [
      &#39;label&#39;=>&#39;公司名&#39;,
      &#39;attribute&#39;=>&#39;companies_company_id&#39;,
      &#39;value&#39;=>&#39;companiesCompany.company_name&#39;
    ],
     //添加的代码结束
    &#39;companiesCompany.company_name&#39;,
    // &#39;branch_id&#39;,
    // &#39;companies_company_id&#39;,
    &#39;branch_name&#39;,
    &#39;branch_address&#39;,
    &#39;branch_created_date&#39;,
    // &#39;branch_status&#39;,
    [&#39;class&#39; => &#39;yii\grid\ActionColumn&#39;],
  ],
]); ?>

登入後複製

然後修改SearchBranches.php

修改rules方法為：

public function rules()
{
  return [
    [[&#39;branch_id&#39;], &#39;integer&#39;],
    [[&#39;branch_name&#39;, &#39;branch_address&#39;, &#39;branch_created_date&#39;, &#39;branch_status&#39;,&#39;companies_company_id&#39;], &#39;safe&#39;],
  ];
}

登入後複製

修改search方法：

public function search($params)
{
  $query = Branches::find();
  $dataProvider = new ActiveDataProvider([
    &#39;query&#39; => $query,
  ]);
  $this->load($params);
  if (!$this->validate()) {
    // uncomment the following line if you do not want to any records when validation fails
    // $query->where(&#39;0=1&#39;);
    return $dataProvider;
  }
  // 添加下面这行代码
  $query->joinWith(&#39;companiesCompany&#39;);
  $query->andFilterWhere([
    &#39;branch_id&#39; => $this->branch_id,
  //  &#39;companies_company_id&#39; => $this->companies_company_id,
    &#39;branch_created_date&#39; => $this->branch_created_date,
  ]);
  $query->andFilterWhere([&#39;like&#39;, &#39;branch_name&#39;, $this->branch_name])
    ->andFilterWhere([&#39;like&#39;, &#39;branch_address&#39;, $this->branch_address])
    ->andFilterWhere([&#39;like&#39;, &#39;branch_status&#39;, $this->branch_status])
     // 添加下面这行代码
    ->andFilterWhere([&#39;like&#39;, &#39;companies.company_name&#39;, $this->companies_company_id]);
  return $dataProvider;
