我使用以下(简单)代码将模型与yii2中的表单一起使用:
class ChooseAgeCategoriesForm extends Model
{
public $ageCategories;
/**
* @return array the validation rules.
*/
public function rules()
{
return [
['ageCategories', 'safe'],
[['ageCategories'], 'each', 'rule' => ['integer']],
];
}
}
但是,然后尝试加载这样的模型:
$model = new ChooseAgeCategoriesForm();
if ($model->load(Yii::$app->request->post())) {
$acIDs = $model->ageCategories;
}
代码永远不会执行。实际上,$model->load
会返回Bool(false)
,但$model->errors
为空。转储post
的内容会产生以下结果:
array(2) { ["_csrf"]=> string(56) "SzhjdWIuc0oIQSA0BEs4BDp8KzYEXwM5CG80RhNBRDkPUzIXO1gBew==" ["ageCategories"]=> array(9) { [0]=> string(1) "1" [1]=> string(1) "2" [2]=> string(1) "3" [3]=> string(1) "4" [4]=> string(1) "5" [5]=> string(1) "6" [6]=> string(1) "7" [7]=> string(1) "9" [8]=> string(2) "10" } }
所以是的,该字段实际上是发送并填充了一组数字。我在这里看不到什么,问题是什么?提前致谢。我还尝试将['ageCategories', 'exist', 'allowArray' => true],
添加为另一个规则,但这也不起作用。有什么想法吗?
表单代码
根据要求,表单代码本身:
<?php $form = ActiveForm::begin([
'action' => Url::to(['/result/team-result']),
'method' => 'post',
'options' => ['id' => 'chooseAgeCategory', 'style' => "margin-bottom: 15px;"]
]); ?>
<?= Select2::widget([
'name' => 'ageCategories',
'id' => 'ac-id',
'value' => $acIDs,
'data' => ArrayHelper::map(AgeCategory::find()->all(), 'id', 'name'),
'options' => ['multiple' => true, 'placeholder' => Yii::t('view', 'Select Age Category')],
'pluginEvents' => [
"change" => "function() { this.form.submit(); }",
]
]) ?>
<?php $form->end(); ?>

我建议您使用Select2
属性model
,以便自动链接到缓和加载过程的字段,并使用模型的验证功能:
<?= Select2::widget([
'name' => 'ageCategories',
'id' => 'ac-id',
'value' => $acIDs,
'data' => ArrayHelper::map(AgeCategory::find()->all(), 'id', 'name'),
'options' => ['multiple' => true, 'placeholder' => Yii::t('view', 'Select Age Category')],
'pluginEvents' => [
"change" => "function() { this.form.submit(); }",
]
]) ?>

请更改您的select2小部件代码,如下所示。 Yii2包装模型名称,字段名称为
ChooseAgeCategoriesForm [ageCategories]
如果您检查表格,您就会知道。所以你必须在select2小部件中给出模型值。
<?= Select2::widget([
'model' => $model,
'attribute' => 'ageCategories',
'id' => 'ac-id',
'value' => $acIDs,
'data' => ArrayHelper::map(AgeCategory::find()->all(), 'id', 'name'),
'options' => ['multiple' => true, 'placeholder' => Yii::t('view', 'Select Age Category')],
'pluginEvents' => [
"change" => "function() { this.form.submit(); }",
]
]) ?>
