RadioList似乎不被渲染

Question

以下代碼應該搜索日期記錄。但是，不管我點擊，在其他的代碼分支將被處理

<?=$form->field($model, 'choice_date')->radioList(array(0=>'Before',1=>'After'))->label('Please, choose Datesearching!'); ?> 

型號：

<?php 
 

 
namespace backend\models; 
 

 
use Yii; 
 
use yii\base\Model; 
 

 
class RadioForm extends Model { // A new Class programmed by Thomas Kipp 
 

 
    public $choice_date; 
 

 

 
    public function rules() { 
 
     return [ 
 
      ['choice_date', 'boolean'], 
 
     ]; 
 
    } 
 

 
} 
 
?>

搜索類：

<?php 
 

 
namespace backend\models; 
 

 
use Yii; 
 
use yii\base\Model; 
 
use yii\data\ActiveDataProvider; 
 
use backend\models\Departments; 
 

 
class DepartmentsSearch extends Departments { 
 

 
    public function rules() { 
 
     return [ 
 
      [['department_id'], 'integer'], 
 
      [['department_name', 'department_created_date', 'department_status', 'companies_company_id', 'branches_branch_id'], 'safe'], 
 
     ]; 
 
    } 
 

 
    public function scenarios() { 
 

 
     return Model::scenarios(); 
 
    } 
 

 
    public function search($params) { 
 
     $query = Departments::find(); 
 
     $dataProvider = new ActiveDataProvider([ 
 
      'query' => $query, 
 
     ]); 
 

 
     $this->load($params); 
 

 
     if (!$this->validate()) return $dataProvider; 
 
     
 
     $model = new RadioForm(); 
 
     $model->load($params); 
 
     if ($model->choice_date == true) 
 
      $query->andFilterWhere(['<', 'department_created_date', $this->department_created_date]); 
 
     else 
 
      $query->andFilterWhere(['>', 'department_created_date', $this->department_created_date]); 
 
     $query->joinWith('companiesCompany'); 
 
     $query->joinWith('branchesBranch'); 
 

 
     $query->andFilterWhere(['like', 'department_name', $this->department_name]) 
 
       ->andFilterWhere(['like', 'companies.company_name', $this->companies_company_id]) 
 
       ->andFilterWhere(['like', 'branches.branch_name', $this->branches_branch_id]) 
 
       ->andFilterWhere(['like', 'department_status', $this->department_status]); 
 

 
     return $dataProvider; 
 
    } 
 

 
}

P.S：我只是很能影響日期過濾改變特性真/假，比如像這樣：

public $choice_date=true; 

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

任何想法，如何解決這一問題？

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Answer 1

RadioForm模型有一個默認值0的屬性$choice_date（最初你寫public $choice_date = 0;）。在search()方法您寫道：

$model = new RadioForm(); 
if ($model->choice_date == 0) 
/* ... */ 

這在理論上應該總是返回true因爲你還沒有分配任何值呢。您創建了一個變量$choice_date在RadioForm模型，所以你還需要增加一個額外的行：

$model = new RadioForm(); 
$model->load($params); 

if ($model->choice_date == 0) 
/* ... */ 

假設$params有一個數組RadioForm模型，這將選定值加載到$choice_data屬性，並會產生影響。
