Question

我有一个DropDownList重复三次，但是我使用了3个模型和3个选择ID来产生差异，但是我获得了与其他模型重复的最后一个相同的值。模型$modelDevisReduction1是表Reduction(type,taux)的模型，因此对于每个选择我都有一个＆＃39; taux＆＃39;。这是我的代码：

 /* Reduction 1 */
<?= $form->field($modelDevisReduction1, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-1'] )->label(false); ?>

<?=  $form->field($modelDevisReduction1,'taux')->textInput(['maxlength' => true,'id'=>'DevisReductionTaux-1'])->label(false); ?>

/* Reduction 2 */
<?= $form->field($modelDevisReduction2, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-2'] )->label(false); ?>

<?=  $form->field($modelDevisReduction2,'taux')->textInput(['maxlength' => true,'id'=>'DevisReductionTaux-2'])->label(false); ?>

/* Reduction 3 */
<?= $form->field($modelDevisReduction3, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-3'] )->label(false); ?>

<?=  $form->field($modelDevisReduction3,'taux')->textInput(['maxlength' => true,'id'=>'DevisReductionTaux-3'])->label(false); ?>

这是控制器actionCreate代码：

public function actionCreate()
{

    $model = new Devis();
    $modelDevisReduction1 = new DevisReduction();
    $modelDevisReduction2 = new DevisReduction();
    $modelDevisReduction3 = new DevisReduction();

    if ($model->load(Yii::$app->request->post()) &&  
    $modelDevisReduction2->load(Yii::$app->request->post()) && 
    $modelDevisReduction1->load(Yii::$app->request->post()) && 
    $modelDevisReduction3->load(Yii::$app->request->post())) {

        echo "Reference => ".$model->reference;
        echo "<br/>";
        echo "dateCreation => ".$model->dateCreation;
        echo "<br/>";
        echo "contact => ".$model->contact;
        echo "<br/>";
        echo "delaiLivraison => ".$model->delaiLivraison;
        echo "<br/>";
        echo "commercial => ".$model->commercial;
        echo "<br/>";
        echo "valableJusqua => ".$model->valableJusqua;
        echo "<br/>";
        echo "dateRelance => ".$model->dateRelance;
        echo "<br/>";
        echo "etat => ".$model->etat;
        echo "<br/>";
        echo "modePaiement => ".$model->modePaiement;
        echo "<br/>";
        echo "delaiPaiement => ".$model->delaiPaiement;
        echo "<br/>";
        echo "<br/>";
        echo "Reduction 1 : ". $modelDevisReduction1->idReduction;
        echo "Taux de Reduction 1 : ". $modelDevisReduction1->taux;
        echo "<br/>";
        echo "Reduction 2 : ". $modelDevisReduction2->idReduction;
        echo "Taux de Reduction 2 : ". $modelDevisReduction2->taux;
        echo "<br/>";
        echo "Reduction 3 : ". $modelDevisReduction3->idReduction;
        echo "Taux de Reduction 3 : ". $modelDevisReduction3->taux;
        echo "<br/>";
        echo "<br/>";
        echo "<br/>";
        echo "<br/>";
        echo "Articl ".$modelArticleDevis->idArticle;

        die;
        /* $model->save();
        return $this->redirect(['index']); */

    } else {
        return $this->render('create', [
            'model' => $model,
            'modelDevisReduction1' => $modelDevisReduction1,
            'modelDevisReduction2' => $modelDevisReduction2,
            'modelDevisReduction3' => $modelDevisReduction3,
        ]);
    }
}

这是表格：

在结果中，我得到了其他人的重复值（Ristourne ID = 3，Taux = 4）

问题出在你的代码中。在actionCreate()中，您创建了三个相同类型DevisReduction的模型对象。

$modelDevisReduction1 = new DevisReduction();
$modelDevisReduction2 = new DevisReduction();
$modelDevisReduction3 = new DevisReduction();

在视图中，您已将代码编写为

<?= $form->field($modelDevisReduction1, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-1'] )->label(false); ?>

<?= $form->field($modelDevisReduction2, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-2'] )->label(false); ?>

<?= $form->field($modelDevisReduction3, 'idReduction')->dropDownList( ArrayHelper::map(Reduction::find()->all(),'idReduction','libelle'), ['prompt'=>'Sélectionner la Reduction','id'=>'DevisReductionType-3'] )->label(false); ?>

但是当 $ modelDevisReduction1时，$ modelDevisReduction2和$ modelDevisReduction 引用了三个相同类型的对象 DevisReduction 。该视图将使用name属性{{1对于字段 $ modelDevisReduction1，$ modelDevisReduction2和$ modelDevisReduction3 。因此，当您提交表单时，将会获取最后一个选择框值（字段$ modelDevisReduction3）。这恰好发生在您的案例中。对于输入字段DevisReduction[idReduction]的情况。您可以进一步确认。

检查渲染的视图html。
检查表单发布数据。

我建议您解决上述问题的方法是创建一个自定义表单模型，如下所示。

DevisReduction[taux]

您的控制器代码应该是

<?php

class DevisReductionForm extends yii\base\Model {

    public $idReduction1;
    public $idReduction2;
    public $idReduction3;
    public $taux1;
    public $taux2;
    public $taux3;

    /**
     * @inheritdoc
     */
    public function rules() {
        $rules = [
                    [['idReduction1', 'idReduction1', 'idReduction1', 'taux1', 'taux2', 'taux3'], 'required'],
        ];

        return array_merge($rules, parent::rules());
    }

}

在你看来

public function actionCreate()
{
    //create object of custom form model DevisReductionForm given above
    $modelDeviceReduction = new DevisReductionForm ();

    if ($modelDeviceReduction->load(Yii::$app->request->post())
    {
         $modelDevisReduction1 = new DevisReduction();
         $modelDevisReduction2 = new DevisReduction();
         $modelDevisReduction3 = new DevisReduction();

         $modelDevisReduction1->idReduction =  $modelDeviceReduction->idReduction1
         $modelDevisReduction2->idReduction =  $modelDeviceReduction->idReduction2
         $modelDevisReduction3->idReduction =  $modelDeviceReduction->idReduction3

         $modelDevisReduction1->taux = $modelDeviceReduction->taux1
         $modelDevisReduction2->taux = $modelDeviceReduction->taux2
         $modelDevisReduction3->taux = $modelDeviceReduction->taux3
          //write other codes


    }
    else
    {
        return $this->render('create', [
            'modelDeviceReduction ' => $modelDeviceReduction ,

        ]);
    }
}

希望你明白这一点。
