我在验证时遇到问题
我如何验证要插入的最小数字
$form->field($modeldetails, "[{$i}]qty")->textInput()
基于表数量字段和要从$form->field($model, 'tgl')筛选的参数的总和，因为我不能简单地在模型规则中添加范围验证。
我需要一个函数来从两个模型($model,$modeldetails)中获取参数，并处理数量的摘要，如果用户插入了超过最小和的值，则在数量字段中显示错误。
查看标题的活动表单字段（使用动态表单）
<?php $form = ActiveForm::begin(['id' => 'dynamic-form')]); ?>
<?= $form->field($model, 'tgl')->widget(DatePicker::classname(), [
'options' => ['placeholder' => 'Enter Transaction Date ...'],
'type' => DatePicker::TYPE_COMPONENT_APPEND,
'pluginOptions' => [
'autoclose'=>true,
'format' => 'yyyy-mm-dd',
'todayHighlight' => true
],
]); ?>
查看活动表单字段以获取详细信息
<?php DynamicFormWidget::begin([
'widgetContainer' => 'dynamicform_wrapper', // required: only alphanumeric characters plus "_" [A-Za-z0-9_]
'widgetBody' => '.container-items', // required: css class selector
'widgetItem' => '.item', // required: css class
'limit' => 15, // the maximum times, an element can be cloned (default 999)
'min' => 1, // 0 or 1 (default 1)
'insertButton' => '.add-item', // css class
'deleteButton' => '.remove-item', // css class
'model' => $modeldetail[0],
'formId' => 'dynamic-form',
'formFields' => [
'id_brg',
'qty',
],
]); ?>
<div class="panel panel-default">
<div class="panel-heading">

if (! $modeldetails->isNewRecord) {
echo Html::activeHiddenInput($modeldetails, "[{$i}]id");
}
?>
<div class="row">
<div class="col-sm-6">
<?= $form->field($modeldetails, "[{$i}]id_brg")->label('Nama')->widget(Select2::classname(), [
'data' => $brg,
'language' => 'en',
'options' => ['placeholder' => 'Select an item ...'],
'pluginOptions' => [
'allowClear' => true

]);?>

<div class="col-sm-6">
<?= $form->field($modeldetails, "[{$i}]qty")->textInput() ?>

</div><!-- .row -->

<?php endforeach; ?>

<?php DynamicFormWidget::end(); ?>
我的模型了解详细信息
class Detail extends 'yii'db'ActiveRecord
{
/**
* @inheritdoc
*/
public static function tableName()
{
return 'detail';
}
/**
* @inheritdoc
*/
public function rules()
{
return [
[['id_brg', 'qty'], 'required'],
[['kode', 'id_brg', 'qty'], 'integer'],
];
}
/**
* @inheritdoc
*/
public function attributeLabels()
{
return [
'id' => 'ID',
'kode' => 'Kode',
'id_brg' => 'ID Barang',
'qty' => 'Qty',
];
}
/**
* @return 'yii'db'ActiveQuery
*/
public function getLinkheader()
{
return $this->hasOne(Transaksi::className(), ['kode' => 'kode']);
}
/**
* @return 'yii'db'ActiveQuery
*/
public function getItems()
{
return $this->hasOne(Barang::className(), ['id' => 'id_brg']);
}
}
核心验证器整数
[['qty'], 'integer', 'min' => 123],
使用自定义验证器。一个简单的例子是内联验证器：
public function rules()
{
return [
[['id_brg', 'qty'], 'required'],
[['kode', 'id_brg', 'qty'], 'integer'],
['qty', function ($attribute, $params) {
/* calculate min value */
$min = 123;
if ($this->$attribute > $min) {
$this->addError($attribute, "Qty must be less than {$min}.");
}
}],
];
}
