I have a field that is a Select2 widget field and it's usually used in many forms, but copy pasting the same code after a while gets really annoying. Therefore I decided perhaps its best to create a widget just for this field.
The field is as follows
<?= $form->field($model, 'contact_id')->widget(Select2::className(), [
'initValueText' => empty($model->contact_id) ? '' : $model->contact->contact_id . ' ' . $model->contact->fullname,
'options' => [
'class' => 'input-sm',
'id' => 'contact_id',
'placeholder' => '-- Search --',
'disabled' => $disabled,
'onchange' => new JsExpression("get_contact_info($(this).val())"),
],
'pluginOptions' => [
'allowClear' => true,
'language' => [
'errorLoading' => new JsExpression("function () { return 'Waiting for results...'; }"),
],
'ajax' => [
'url' => $fetch_url,
'dataType' => 'json',
'data' => new JsExpression('function(params) { return {q:params.term}; }'),
'results' => new JsExpression('function(data,page) { return {results:data.results.text}; }'),
],
'escapeMarkup' => new JsExpression('function (markup) { return markup; }'),
'templateResult' => new JsExpression('function(contact) { return contact.text; }'),
'templateSelection' => new JsExpression('function (contact) { return contact.text; }'),
],
]); ?>
This field utilizes Ajax Fetching, and must allow to be used in create and update forms.
Can anyone please point me to the right direction.
I see two solution:
a) create widget - more work, but flexible using by adding additional settings
b) create separate view and render it - faster, but no so flexible

I am implementing page cache for one of my page. For depenedency, I have to check an array, which can be either exist or not. Possible array keys cane ,
usersearch['id'], usersearch['name'], usersearch['phone]. I have to add dependency for any change in these values as well.
Also, I have to clear cache for any update or add in user table.
Is there any possible solution for this.?
Thanks in advance
You can use variations
public function behaviors(){
$usersearch = Yii::$app->requst->get('usersearch');
return [
[
'class' => 'yii\filters\PageCache',
'only' => ['index'],
'duration' => 60,
'variations' => [
'YOUR_DYNAMIC_VALUE1','YOUR_DYNAMIC_VALUE2'
],
'dependency' => [
'class' => 'yii\caching\DbDependency',
'sql' => 'SELECT COUNT(*) FROM post',
],
],
];
}
Ref link
IN YOUR CASE ,you can use
'variations' => \Yii::$app->requst->get('usersearch')??[],
or
'variations' => [
\/Yii::$app->requst->get('usersearch')['id'] ?? '',
\Yii::$app->requst->get('usersearch')['name'] ?? '',
\Yii::$app->requst->get('usersearch')['phone'] ?? '',
]
You could use a yii\caching\FileCache component with the following configuration.
Firstly, you set the cache in the init function of your controller:
Yii::$app->setComponents([
'yourCacheName' => [
'class' => \yii\caching\FileCache::class,
'defaultDuration' => 1800, //cache duration in seconds
'keyPrefix' => Yii::$app->getSession()->getId(). '_'
]
]);
Here, the parameter keyPrefix is set so that it is linked to the session ID. Thus, the visitors do not see each other's cached page. If the content is static and equal, regardless of the user or the session, this parameter can be removed.
In the view that must be cached you can call the beginCache function and the dependency as follows:
$this->beginCache('cache-id', [
'cache' => Yii::$app->yourCacheName, // the name of the component as set before
'variations' => [
$usersearch['id'] ?? '',
$usersearch['name'] ?? '',
$usersearch['phone'] ?? '',
],
'dependency' => [
'class' => \yii\caching\DbDependency::class,
'sql' => 'SELECT count(*) FROM your_user_table'
]
]);
// your view
$this->endCache();
I have Yii2 application which uses the Kartik plugin to initialize Select2 dropdowns in forms.
I have one particular Select2 which uses AJAX call to get the data for the drop down options.
<?=
$form->field($model, 'court_house_id', ['enableAjaxValidation' => true, 'selectors' => ['input' => '#' . $id . "-court-house"],'template' => FormHelper::GenerateFieldTemplate([6])])
->widget(Select2::classname(), [
'options' => ['id' => $id . "-court-house", 'placeholder' => Yii::t('app', 'Search court house...')],
'hashVarLoadPosition' => \yii\web\View::POS_READY,
'pluginOptions' => [
'dropdownParent' => new JsExpression("$('#$modalWindowId')"),
'allowClear' => true,
'minimumInputLength' => 2,
'language' => [
'errorLoading' => new JsExpression("function () { return '" . Yii::t('app', 'Search...') . "'; }"),
],
'ajax' => [
'url' => app\components\UrlMaker::link('data/court-house-list'),
'dataType' => 'json',
'data' => new JsExpression('function(params) { return {q:params.term}; }')
],
'escapeMarkup' => new JsExpression('function (markup) { return markup; }'),
'templateResult' => new JsExpression('function(courthouse) { return courthouse.text; }'),
'templateSelection' => new JsExpression('function (courthouse) { return courthouse.text;}'),
]])
->label(Yii::t('app', 'Court House'), ['class' => FormHelper::GenerateLabelClassTemplate([3])]);
?>
Intentionally pasting all of the code, although most of it is irrelevant I would assume.
I have this loaded in multiple dynamically created forms thus all the strange ids and selectors. However, the form has different dropdown which controls whether some of the fields are shown (and required) or not. This particular field above is only shown in one of the scenarios which all the other variations of the form do not have it. So the model has the following validation:
[['court_house_id', 'staff'], 'required', 'on' => self::SCENARIO_ONE],
By the way staff is just a regular text field and everything works for it.
In order to change the scenario, I have the following line in the view with the form:
<?php $model->scenario = \app\models\MyModel::SCENARIO_ONE; ?>
The problem is that when I submit the form empty, the staff field gets marked in red as invalid but the court house is marked in green as valid although it is empty.
If I go into the model and remove the 'on' => self::SCENARIO_ONE part then everything works as expected - on empty submit the court house field also lights up in red but that would be a problem for the rest of my scenarios where this field is not needed.
Any ideas what might be causing the problem and how to resolve it?
Try to set the scenario in controller before calling save() method, for example
$model = new MyModel(['scenario' => MyModel::SCENARIO_ONE])
I've been trying to install user-management for Yii2.0, but getting ReflectionException while loading the page. I have attached the error page and directory structure below.
and the file path is as shown below.
I've searched a lot to find out the reason for this, but nothing worked out. can someone tell me what am I missing here to get it work. looks like the user-management installation documentation has some flaws. It is not clear enough to understand. Hope to get the steps to install. Thanks
Here is my console/web.php

return $config;
It seems to have a slight difference with the expected configuration for this extension.
Use this
'class' => 'webvimark\modules\UserManagement\components\UserConfig',
ie UserManagement instead of user-management is a configuration path and not a route
Can anyone help on editable column in gridview.I am using Yii2 and stuck with it.
I can't save data in my model.I can post from gridview column.
In my grid view:
$gridColumns= [
'patient_no',
'category_name',
'sdv_text',
[
'class' => 'kartik\grid\EditableColumn',
'attribute'=>'sdv_status',
'pageSummary' => true,
'editableOptions'=> [
'header' => 'profile',
'format' => Editable::FORMAT_BUTTON,
'inputType' => Editable::INPUT_DROPDOWN_LIST,
'data'=> $StatusList,
]
],
// 'date_sdv_performed',
[
'class' => 'kartik\grid\EditableColumn',
'attribute'=>'date_sdv_performed',
'editableOptions' => [
'header' => 'Date Sdv Performed',
'inputType'=>\kartik\editable\Editable::INPUT_WIDGET,
'format'=>\kartik\datecontrol\DateControl::FORMAT_DATE,
'widgetClass'=> 'kartik\datecontrol\DateControl',
],
],
[
'class' => 'kartik\grid\EditableColumn',
'attribute'=>'comments',
'hAlign' => 'top',
'vAlign' => 'middle',
'width'=>'100px',
'headerOptions' => ['class' => 'kv-sticky-column'],
'contentOptions' => ['class' => 'kv-sticky-column'],
'pageSummary' => true,
],
];
GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'layout'=>"{items}\n{pager}",
'pjax'=>true,
'toolbar' => [
'{export}',
'{toggleData}'
],
'responsive'=>true,
'hover'=>true,
'columns' => $gridColumns
]);
In my controller action:
public function actionMonitoring($site_name)
{
$this->layout = 'sdv-carolina-main';
$Countries = new Countries;
$model = new Flagging;
$searchModel = new FlaggingSearch();
$dataProvider = $searchModel->monitoringsearch($site_name);
$allocatedsites = new AllocatedSites;
if (Yii::$app->request->post('hasEditable'))
{
$model = $this->findModel($model['flagging_id']);
$out = Json::encode(['output'=>'', 'message'=>'']);
$post = [];
$posted = current($_POST['Flagging']);
$post['Flagging'] = $posted;
if ($model->load($post)) {
$model->save();
$output = '';
if (isset($posted['sdv_status']))
{
$output = $model->sdv_status;
}
$out = Json::encode(['output'=>$output, 'message'=>'']);
}
echo $out;
return;
}
return $this->render('monitoring',
[
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
'Countries' => $Countries,
'model'=>$model,
'allocatedsites' => $allocatedsites,
]);
}
The problem is I can't update my model because of I can't get the id.
I just need the id to update specific row.How can I get the id while using editable column?
Thanks in advance.
Actually the solution is easy. I just need the id of that specific row to update that.And in my ajax post I got something like this:
Flagging[0][status] NO
_csrf TlhyUm5kajAoNxgVNy0/ZCoyHApZUlNUFh0rB1gRPGoAFSIdGSAifQ==
editableIndex 0
editableKey 13
hasEditable 1
and found the editableKey is the id of that specific row!
Now in my controller I write down this code given below:
$_id=$_POST['editableKey'];
$model = $this->findModel($_id);
Here $_id is the posted editableKey value which is the id of the specific row.
and with the id I use it to get the specific model and just update data based on that id.
[
'attribute' => 'status',
'format' => 'html',
'value' => function ($data) {
if($data->status==true) {
return Html::a("Inactive", "#", ['id' => $data->id, 'class' => 'a_status']);
}
else {
return Html::a("Active", "#");
}
]
The problem is, this code is not returning "id" attribute in link. So, wanted to know if this is currect way to put link in grid view or can someone point me correct way?'
Thx in advance.
Your code is missing one closing parenthesis and a change in format key's value -
Try -
[
'attribute' => 'status',
'format' => 'raw', //It was 'html' before
'value' => function ($data) {
if($data->status==true) {
return Html::a("Inactive", "#", ['id' => $data->id, 'class' => 'a_status']);
}
else {
return Html::a("Active", "#");
}
} //missing parenthesis
]
Well, you are missing a lot of code. Here are some observations.
*) I am using this kind of definition for the column
'value'=>function ($model, $key, $index, $widget) {
I am not sure if it makes a difference, try it this way maybe this is the problem.
Other things:
*) why are you using return
Html::a("Inactive", "#", ['id' => $data->id, 'class' => 'a_status']);
and not something like
Html::a("Inactive", ['change-status', 'status' => 'active', 'id' => $data->id], ['class' => 'a_status']);
You are creating in this way the link with the proper url already. If somebody does not have javascript enabled it will still work for them, just with a refresh.
Now you can create a global ajax function that you can reuse with ease for a lot more screens.
Now the actionChangeStatus function can end like this
if(Yii::$app->request->getIsAjax()) {
Yii::$app->response->format = 'json';
return ['success' => true];
} else {
return $this->redirect(['index']);
}
My ajax looks like this
jQuery.ajax({
"type": "GET",
"url": element.attr('href'),
"cache": false,
})
.success(function ( response ) {
$.pjax.reload({container: "#main-pjax", async:false, timeout: 4000});
});
