如何获取最后插入记录 - Yii 2

Question

我正在申请创建条形码在我的应用程序中，我想创建 Barang 但在发行单中我希望从最后一张发行单自动填写发行单我该怎么做才能解决它？

这是我的看法

<?php

use yii\helpers\Html;
use yii\widgets\ActiveForm;

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

<div class="barang-form">

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

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

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

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



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

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

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

</div>

 <div class="row">
    <?= $form->field($model, 'berat')->textInput(['maxlength' => true]) ?>
    <?php echo  \Yii::$app->db->getLastInsertId('{{barang}}');?>

  </div>

Answer 1

渲染前在控制器中

public function actionCreate()
{
    $model = new Barang();
    $modelForSlip = Barang::find()->orderBy(['id'=> SORT_DESC])->one();
    $model->issue_slip = $modelForSlip->issue_slip;

    if ($model->load(Yii::$app->request->post())){

       $model->waktu = date('Y-m-d h:m:s');
       $model->user = \Yii::$app->user->identity->username;
       $model->save();

        return $this->redirect(['view', 'id' => $model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
         //$model->issue_slip= \Yii::$app->db->getLastInsertId();
    }
}

Answer 2

假设这是您的创建函数：

 public function actionCreate()
    {
        $model = new Modal();

        if ($model->load(Yii::$app->request->post()) && $model->save()) {
             return $this->redirect(['update', 'id' => $model->Id]);
        } else {
            return $this->render('create', [
                'model' => $model,
            ]);
        }
    }

然后重定向到最后插入的新页面 ID 现在让你像这样更新功能

 public function actionUpdate($id)
        {
            $model2 = Model::findOne($id);
            $model = new Modal();
 $model->issue_slip = $model2['issue_slip'];




            if ($model->load(Yii::$app->request->post()) && $model->save()) {
                return $this->redirect(['view', 'id' => $model->Id]);
            } else {
                return $this->render('update', [
                    'model' => $model,
                ]);
            }
        }

在YII2中你可以轻松获取save()函数后最后插入的记录

喜欢

 $model->save();
echo $model->Id

或者你想得到的任何列而不是 issue_slip 你可以使用你想要的任何列
