我正在尝试使用select2查询数据库，因为有30000条记录，这实际上是我能想到的唯一有效的方法。
我的问题是，如果我只提交此表单，pole_id不会更新。
有人可以帮助jQuery获取ID或告诉我为什么选择框不更新数据库中的pole_id字段吗？

alert(id);
});

两个部分：
我决定在控制器操作中使用var_dump：
这是导致我发现ID为：selectbox_pole_id的隐藏字段的地方。
因此，我重命名了该ID以匹配数据库ID pole_id，并在保存之前添加了以下行：$ model-> pole_id = $ _POST ['pole_id'];
public function actionCreate()
{
$model=new Jpapoles;
// Uncomment the following line if AJAX validation is needed
// $this->performAjaxValidation($model);
if(isset($_POST['Jpapoles']))
{
$model->attributes=$_POST['Jpapoles'];
$model->pole_id = $_POST['pole_id'];
if($model->save())
//$this->redirect(array('jpas/view','id'=>$_GET['jpano']));
var_dump($_REQUEST);
//echo $_POST['pole_id'];
}
$this->renderPartial('create',array(
'model'=>$model
),false,true);
}
/* @var $this JpapolesController */
/* @var $model Jpapoles */
/* @var $form CActiveForm */
?>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'jpapoles-form',
'enableAjaxValidation'=>false,
)); ?>
<p class="note">Fields with <span class="required">*</span> are required.</p>
<?php echo $form->errorSummary($model); ?>
<div class="row">
<?php echo $form->labelEx($model,'pole_id'); ?>
<?php
echo CHtml::hiddenField('pole_id', '', array('class' => 'span5'));
$this->widget('ext.select2.ESelect2',array(
'id'=>'myselect',
'selector' => '#pole_id',
'model'=>$model,
'attribute'=>'pole_id',
'options' => array(
'allowClear'=>true,
'placeholder'=>'Select a Pole',
'minimumInputLength' => 3,
'ajax' => array(
'url' => Yii::app()->createUrl('jpapoles/poles'),
'type'=>'GET',
'dataType' => 'json',
'quietMillis'=> 100,
'data' => 'js: function(text,page) {
return {
q: text,
page_limit: 10,
page: page,
};
}',
'results'=>'js:function(data,page) { var more = (page * 10) < data.total; return {results: data, more:more };
}
',
),
),
));
?>
<?php echo $form->error($model,'pole_id'); ?>
</div>
<div class="row">
<?php echo $form->labelEx($model,'member_id'); ?>
<?php //echo $form->textField($model,'member_id'); ?>
<?php
$list = CHtml::listData(Members::model()->findAll(array('order' => 'abriviation')), 'id', 'abriviation');
echo $form->dropDownList($model, 'member_id', $list);

<?php echo $form->error($model,'member_id'); ?>

<?php echo $form->error($model,'jpa_id'); ?>
</div>
<div class="row buttons">
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>
</div>
<?php $this->endWidget(); ?>
</div><!-- form -->
<script type="text/javascript">
// Or for single select elements:
$("#select").select2({
initSelection : function (element, callback) {
var data = {id: element.val(), text: element.val()};
callback(data);
}
});
</script>

您可以仅使用CActiveForm::hiddenField()生成此隐藏的输入：
<div class="row">
<?php echo $form->labelEx($model, 'pole_id'); ?>
<?php
echo $form->hiddenField($model, 'pole_id', ['id'=>'pole_id']);
$this->widget('ext.select2.ESelect2', [
'id' => 'myselect',
'selector' => '#' . CHtml::activeId($model, 'pole_id'),
'options' => [
'allowClear' => true,
'placeholder' => 'Select a Pole',
'minimumInputLength' => 3,
'ajax' => [
'url' => Yii::app()->createUrl('jpapoles/poles'),
'type' => 'GET',
'dataType' => 'json',
'quietMillis' => 100,
'data' => 'js: function(text,page) {
return {
q: text,
page_limit: 10,
page: page,
};
}',
'results' => 'js:function(data,page) {
var more = (page * 10) < data.total; return {results: data, more:more };
}',
],
],
]);
?>
<?php echo $form->error($model, 'pole_id'); ?>
</div>
它将正确处理现有数据，并且在控制器中不需要特殊操作即可处理此输入-$model->attributes = $_POST['Jpapoles']会将pole_id加载为任何其他属性。
但是此扩展也应该非常适用于模型，因此您可以使用：
$this->widget('ext.select2.ESelect2', [
'model' => $model,
'attribute' => 'pole_id',
'options' => [
// ...
],
]);
您无需自己创建隐藏文件。
