當選擇下拉列表中的值時不會顯示

Question

我有兩張彼此相互關聯的表格，即丈夫和妻子。我已經創建了我的價值下拉列表並從表格丈夫處獲取數據。我希望在選擇其值時不會出現在他的下拉列表中。也許還有其他參考資料或可以提供幫助。代碼可以在下面的圖片中看到。

<?php 

use yii\helpers\Html; 
use yii\widgets\ActiveForm; 
use yii\helpers\ArrayHelper; 
use app\models\Husband; 

/* @var $this yii\web\View */ 
/* @var $model app\models\Wife */ 
/* @var $form yii\widgets\ActiveForm */ 
?> 

<div class="wife-form"> 

    <?php $form = ActiveForm::begin(); ?> 

    <?= $form->field($model, 'id_husband')->dropDownList(
     ArrayHelper::map(Husband::find()->where('status' => 0)->all(), 'id_husband', 'name'), 
     ['prompt' => 'Pilih']  
    ) ?> 

    <?= $form->field($model, 'name')->textInput(['maxlength' => true]) ?> 

    <?= $form->field($model, 'status')->dropDownList(['0' => 'Tidak Aktif', '1' => 'Aktif'], 
    ['prompt'=>'--Pilih--', 'style' => 'width:380px']) ?> 

    <div class="form-group"> 
     <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?> 
    </div> 

    <?php ActiveForm::end(); ?> 

</div>

Answer 2

你忘了說，在WHERE條件數組。

使用->where(['status' => 0])" instead of "->where('status' => 0)

因此，它是：

<?= $form->field($model, 'id_husband')->dropDownList(
     ArrayHelper::map(Husband::find()->where(['status' => 0])->all(), 'id_husband', 'name'), 
     ['prompt' => 'Pilih']  
    ) ?>
