表单输入自动编号yii2错误

Question

我尝试使用扩展名mdmsoft / yii2-autonumber使用自动编号进行表单输入。而这个结果在我的浏览器中如此吼叫。 这是我的代码形式。

<?php

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

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

<div class="donatur-form">

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

    <?= $form->field($model, 'kode_donatur')->textInput(['readonly' => true, 'value' => 'kode_donatur']) ?>

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

    <?= $form->field($model, 'alamat')->textArea(['rows' => 6]) ?>

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

    <div class="form-group">
        <?= Html::submitButton($model->isNewRecord ? 'Simpan' : 'Ubah', ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
        <?php
		echo "&nbsp";
		echo "&nbsp"; 
		echo Html::a('Keluar', ['index'],['class'=>'btn btn-primary']);
		?>
    </div>

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

</div>

我希望在文本字段“Kode donatur”中显示自动编号。在下图中可以看到一个例子。

控制器中的代码

你的behavior（）函数不在它应该在你的控制器中的模型中。就像这样，

 public function behaviors()
{
    return [
        'verbs' => [
            'class' => VerbFilter::className(),
            'actions' => [
                'delete' => ['POST'],
            ],
        ],
        [
          'class' => 'mdm\autonumber\Behavior',
        'attribute' => 'kode_donatur', // required
        //'group' => $this->id_branch, // optional
        'value' => 'D'.'?' , // format auto number. '?' will be replaced with generated number
        'digit' => 4 // optional, default to null. 
        ],
    ];
}
