在<form method="POST">
<fieldset>
<div class="form-group">
@Html.TextBoxFor(m => m.subid, new { @class = "form-control", @placeholder = "Email" }) >
</div>
<button href="" class="btn btn-gm btn-success">View</button>
</fieldset>
_search.php之后
我使用Kartik DateRange来获取两个日期之间的数据。 这是我的代码：
index.php我使用explode函数来获取我通过的日期，并且我得到一个真实的数据，它工作正常。 我的searchModel代码：
<?= $form->field($model, 'date', [
'addon'=>['prepend'=>['content'=>'<i class="glyphicon glyphicon-calendar"></i>']],
'options'=>['class'=>'drp-container form-group']
])->widget(DateRangePicker::classname(), [
'useWithAddon'=>true
]);
?>
我提交表单后将参数传递给<?php
namespace app\models;
use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use app\models\patientservices;
class patientservicesSearch extends patientservices
{
public function rules()
{
return [
[['id', 'price'], 'integer'],
[['patient_id', 'doctor_id','service_id','date','state'], 'safe'],
];
}
public function scenarios()
{
return Model::scenarios();
}
public function search($params)
{
$query = patientservices::find();
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => array('pageSize' => 150),
]);
$this->load($params);
if (!$this->validate()) {
if ( ! is_null($this->date) && strpos($this->date, ' - ') !== false ) {
list($start_date, $end_date) = explode(' - ', $this->date);
$query->andFilterWhere(['between', 'date', $start_date, $end_date]);
$this->date = null;
}
return $dataProvider;
}
$query->joinWith('patient');
$query->joinWith('service');
$query->joinWith('doctor');
$query->andFilterWhere([
'patient_services.id' => $this->id,
'patient_services.price' => $this->price,
]);
$query->andFilterWhere(['like','patient.patient_name',$this->patient_id]);
$query->orFilterWhere(['=','patient.patient_id',$this->patient_id]);
$query->andFilterWhere(['like','services.service_name',$this->service_id]);
$query->andFilterWhere(['like','doctors.doctor_name',$this->doctor_id]);
if ( ! is_null($this->date) && strpos($this->date, ' - ') !== false ) {
list($start_date, $end_date) = explode(' - ', $this->date);
$query->andFilterWhere(['between', 'date', $start_date, $end_date]);
$this->date = null;
}
$total = 0;
if (!empty($dataProvider->getModels())) {
foreach ($dataProvider->getModels() as $key => $val) {
$total += $val->price;
}
}
return $dataProvider;
}
}
然后我们知道，那么日期范围变为空，其他字段不会变空我需要回显我传递给{{1的参数特别是日期范围。我不知道这里有什么问题。
答案 0 :(得分：1)
看起来是date值没有加载到searchModel，否则它会显示在字段中，即使您在调用之前手动将值分配给字段，如下所示view。我假设searchModel名称为ProductSearch
$params['ProductSearch']['date']='2018-05-20 - 2018-05-23';
$dataProvider=$model->search($params);
$this->render('search',['model'=>$model]);
所以转到您的模型并将date字段与其他列出的<{1}}规则一起添加
safe如果此字段不是数据库表的一部分并且仅为搜索目的而创建，那么您应该在public function rules() {
return [
[ [ 'id' ] , 'integer' ] ,
[ [ 'some_field', 'some_other_field', 'date' ] , 'safe' ] ,
];
}
内将此字段声明为该类的公共属性
searchModelpublic $date;
添加搜索模型后，您似乎将EDIT字段设置为date，因此很明显，一旦成功搜索，它就不会显示给您，因此在{{1}内部在计算null之前结束函数，从条件中删除行search($params)
$total
