在我的上一个问题之后，我一直在yii2上发票并遇到了一个新问题。在您填写表单并单击创建后，除了刷新页面和清除产品字段之外，它并没有做任何事情，但是公司名称和日期等个人信息在刷新后仍然填写...也在我检查数据库什么也没发生。你能看一下下面的代码吗？
发票表格
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
use wbraganca\dynamicform\DynamicFormWidget;
use kartik\datecontrol\Module;
use kartik\datecontrol\DateControl;

use yii\helpers\ArrayHelper;
use app\models\Companies;
use app\models\Spokepersons;
/* @var $this yii\web\View */
/* @var $model app\models\Facturen */
/* @var $form yii\widgets\ActiveForm */
?>
<div class="facturen-form">
<?php $form = ActiveForm::begin(['id' => 'dynamic-form']); ?>
<?= $form->field($model, 'company_name')->widget(Select2::classname(), [

'language' => 'nl',

'pluginOptions' => [
'allowClear' => true
],
])?>
<?= $form->field($model, 'spokes_person')->widget(Select2::classname(), [
'data' => ArrayHelper::map(Spokepersons::find()->all(), 'person_id', 'first_name'),
'language' => 'nl',
'options' => ['placeholder' => 'Selecteer een contactpersoon'],
'pluginOptions' => [

])?>
<?= $form->field($model, 'date')->widget(DateControl::classname(), [
'type' => 'date',

<div class="row">
<div class="panel-body">

'model' => $modelProducten[0],
'formId' => 'dynamic-form',
'formFields' => [

'price',
],
]); ?>
<div class="container-items"><!-- widgetContainer -->
<?php foreach ($modelProducten as $i => $modelProduct): ?>
<div class="item panel panel-default"><!-- widgetBody -->
<div class="panel-heading">

<div class="panel-body">

}
?>
<div class="row">
<div class="col-sm-3">
<?= $form->field($modelProduct, "[{$i}]product_id")->textInput(['maxlength' => true]) ?>
</div>
<div class="col-sm-3">
<?= $form->field($modelProduct, "[{$i}]product_name")->textInput(['maxlength' => true]) ?>
</div>
<div class="col-sm-3">
<?= $form->field($modelProduct, "[{$i}]amount")->textInput(['maxlength' => true]) ?>
</div>
<div class="col-sm-3">
<?= $form->field($modelProduct, "[{$i}]price")->textInput(['maxlength' => true]) ?>
</div>
</div><!-- .row -->
</div>
</div>
<?php endforeach; ?>
</div>
<?php DynamicFormWidget::end(); ?>
</div>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', ['class' => 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
</div>
我认为这不是问题所在，因为表单有效但仍然可以使用。
创建功能
public function actionCreate()
{
$model = new Facturen();
$modelProducten = [new Producten];
if ($model->load(Yii::$app->request->post()) && $model->save())
{
$modelProducten = Model::createMultiple(Producten::classname());
Model::loadMultiple($modelProducten, Yii::$app->request->post());
// validate all models
$valid = $model->validate();
$valid = Model::validateMultiple($modelProducten) && $valid;
if ($valid) {
$transaction = \Yii::$app->db->beginTransaction();
try {
if ($flag = $model->save(false)) {
foreach ($modelProducten as $modelProduct)
{
$modelProduct->factuur_id = $model->id;
if (! ($flag = $modelProduct->save(false))) {
$transaction->rollBack();
break;
}
}
}
if ($flag) {
$transaction->commit();
return $this->redirect(['view', 'id' => $model->id]);
}
} catch (Exception $e) {
$transaction->rollBack();
}
}
}
else {
return $this->render('create', [
'model' => $model,
'modelProducten' => (empty($modelProducten)) ? [new Producten] : $modelProducten
]);
}
}
最后是Model.php
<?php
namespace app\models;
use Yii;
use yii\helpers\ArrayHelper;
class Model extends \yii\base\Model
{
/**
* Creates and populates a set of models.
*
* @param string $modelClass
* @param array $multipleModels
* @return array
*/
public static function createMultiple($modelClass, $multipleModels = [])
{
$model = new $modelClass;
$formName = $model->formName();
$post = Yii::$app->request->post($formName);
$models = [];
if (! empty($multipleModels)) {
$keys = array_keys(ArrayHelper::map($multipleModels, 'id', 'id'));
$multipleModels = array_combine($keys, $multipleModels);
}
if ($post && is_array($post)) {
foreach ($post as $i => $item) {
if (isset($item['id']) && !empty($item['id']) && isset($multipleModels[$item['id']])) {
$models[] = $multipleModels[$item['id']];
} else {
$models[] = new $modelClass;
}
}
}
unset($model, $formName, $post);
return $models;
}
}
我希望你们能在我的代码中发现问题，并告诉我当你找到一个探测器时我做错了什么。我试图学习这个框架而不是真的想放弃
答案 0 :(得分：0)
您要为同一型号召唤$model->save()两次。
第二个例子：
if ($flag = $model->save(false))将返回0，因为第二次更新不会影响表格中的任何行
使用if ( $model->save(false)!==false)检查更新是否成功。
