'value' function doesn't work in Yii2 view - yii2

in my view I'm trying to add 'value' function, which shows the field if the id = 0, otherwise it doesn't show it. I'm trying to do it like so:
echo $form->field($model, 'test', [
'options' => [
'class' => $twoColumns . ' required',
'value' => function ($model) {
return $model->testvar == 0 ? 'Test' : null;
}
]
])
I've added function into 'value', but somehow it doesn't work. Could someone explain me why?
I'm getting htmlspecialchars error

Closure here is not supported and there is no reason to use it anyway.
You only need something like:
$model->interest = null;
if ($model->is_interest_variable == 0) {
$model->interest = 'Test';
}
echo $form->field($model, 'interest', [
'addon' => [
'append' => [
'content' => '%',
],
],
'options' => [
'class' => $twoColumns . ' required',
]
])->textInput([
'placeholder' => '0.0000',
'class' => 'form-control amount-4'
]);

How to add error messages for DateValidation?

In my model I use DateValidation
['date_birthday', 'date', 'format' => 'd.m.yy', 'min' => '01.01.1900', 'max' => date('d.m.yy'), 'tooSmall'=>'The date is from past. Try another','tooBig' => 'The date is from future. Try another', 'message' => 'Try to input the date'],
In view I call the widget
<?php echo $form->field($modelForm, 'date_birthday')->widget(\kartik\date\DatePicker::classname(), [
'type' => \kartik\date\DatePicker::TYPE_COMPONENT_APPEND,
'pickerButton' => false,
'options' => [
'placeholder' => '',
],
'pluginOptions' => [
'format' => 'dd.mm.yyyy',
'autoclose' => true,
'showMeridian' => true,
'startView' => 2,
'minView' => 2,
]
]) ?>
It checks for min and max dates, but show no error message. I think its because of different date formats in model and view. How to fix it?
If you submit form you will see error messages. According to this issue https://github.com/yiisoft/yii2/issues/7745 yii2 have not client-side validations of date
You can enable ajax validation. Add in create and update action before if statement
if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
Yii::$app->response->format = yii\web\Response::FORMAT_JSON;
return ActiveForm::validate($model);
}
And add use yii\widgets\ActiveForm; on the top of controller class. In your _form.php file enable ajax for whole form
<?php $form = ActiveForm::begin([
'enableAjaxValidation' => true,
]); ?>
, or for the field only
<?php echo $form->field($model, 'date_birthday', ['enableAjaxValidation' => true])->widget(\kartik\date\DatePicker::classname(), [
...
Also, you can add plugin options for limit date with startDate and endDate (https://bootstrap-datepicker.readthedocs.io/en/latest/options.html#startdate)
<?php echo $form->field($model, 'date_birthday', ['enableAjaxValidation' => true])->widget(\kartik\date\DatePicker::classname(), [
'type' => \kartik\date\DatePicker::TYPE_COMPONENT_APPEND,
'pickerButton' => false,
'options' => [
'placeholder' => '',
],
'pluginOptions' => [
'format' => 'dd.mm.yyyy',
'autoclose' => true,
'showMeridian' => true,
'startView' => 2,
'minView' => 2,
'startDate' => '01.01.1900',
'endDate' => date('d.m.Y'),
]
]) ?>

Yii2 Custom filter Dropdown for gridview

I am trying to add a custom filter named Sort By Month in the grid view header here is an example of the previous version of the site which I am revamping see below image
I was looking into the layout option of the grid view and added a drop-down in the layout template before {items}
GridView::widget(
[
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'layout' => '{summary}{errors}' . \kartik\widgets\Select2::widget(
[
'model' => $searchModel,
'attribute' => 'filter_month',
'theme' => \kartik\widgets\Select2::THEME_DEFAULT,
'data' => $searchModel->getFilterMonths(),
'pluginEvents' => [
"select2:select" => 'function() { $("#w2").submit();}',
// 'select2:select'=> new \yii\web\JsExpression("function(){console.log('here')}"),
],
'options' => [
'placeholder' => '--Select Month--',
],
'pluginOptions' => [
'allowClear' => true,
'width' => '160px',
],
]
) . '{items}{pager}',
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'name',
'title',
'catalog',
'upc_code',
[
'attribute' => 'created_on',
'label' => 'Created On',
'filter' => \yii\jui\DatePicker::widget(['dateFormat' => 'yyyy-MM-dd', 'model' => $searchModel, 'attribute' => 'created_on']),
'format' => 'html',
],
[
'attribute' => 'status',
'label' => 'Status',
'format' => 'raw',
'value' => function ($data) {
switch ($data->status) {
case 0:
return "Being Edited (" . $data->created_on . ")";
break;
case 1:
return ($data->maxdate == '') ? 'Active' : 'Active';
break;
case 2:
return "Expired";
break;
}
},
],
['class' => 'yii\grid\ActionColumn'],
],
]
);
Now I want to submit the filters form when I select an option from the drop-down, but could not figure out how to attach the default filter submit event with the drop-down options so that it filters the results when I select any option in the drop-down.
For Custom filter you have used the perfect layout but you have to provide your custom field as a filterSelector.
"filterSelector" => "#". Html::getInputId($searchModel, 'AttributeName'),

Setting empty text in kartik dynagrid

Am using kartik dynagrid and i would like to setup a text that shows when the dataprovider returns empty
The grid
echo DynaGrid::widget([
'columns' => $columns,
'showPersonalize' => true,
'emptyText'=>'Sorry all pr have pritems',///-----------------This is what i had set
'options' => ['id' => 'assignsolic-grid'],
'gridOptions' => [
'options' => ['id' => 'grid'],
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'showPageSummary'=>false,
'pager' => [
'firstPageLabel' => 'First',
'lastPageLabel' => 'Last',
'maxButtonCount' => 10,
],
'panel' => [
'type' => GridView::TYPE_PRIMARY,
// 'heading' => '<h3 class="panel-title"><i class="glyphicon glyphicon-book"></i> </h3>',
'before'=>'<i>Select the Prs to assign solicitation and then click the Assign Solicitation button</i>',
'after' =>
Html::button(' <i class=" glyphicon glyphicon-road "></i> Assign Solicitation ', ['value' => Url::to('assignsolc'),'class' => 'btn btn-danger', 'id' => 'assignsolic']),
'footer' => false
],
'toolbar' => [
['content' => '{dynagridFilter}{dynagridSort}{dynagrid}'],
'{export}',
'{toggleData}'
],
'pjax' => true,
'bordered' => false,
'striped' => true,
'condensed' => true,
'responsive' => true,
'responsiveWrap' => false,
'containerOptions'=>['style'=>'overflow:scroll'],
]
]) ;
This returs an error of Setting unknown property: kartik\dynagrid\DynaGrid::emptyText how can i set the empty text
You can define the value for null display directly in confi/main.php formatter component
'components' => [
.......
'formatter' => [
'class' => 'yii\i18n\Formatter',
'dateFormat' => 'dd.MM.yyyy',
'decimalSeparator' => ',',
'thousandSeparator' => ' ',
'currencyCode' => 'EUR',
'nullDisplay' => '', // **** this param
],
.....
Otherwise if the widget don't provide a proper attribute you can use an anonymous function for value
[
'attribute' => 'your_attribute',
'value' => function ($model) {
if ( $model->your_attribute == NULL) {
return 'Sorry all pr have pritems';
} else {
return $model->your_attribute;
}
},
],
Since am using $dataProvider i found out that i just have to check if the dataProvider is empty by
if (!$dataProvider->totalCount > 0) { pass in message to display }
else{?>
SHOW THE GRID HERE
<?php
}
?>
?>

Yii2-editable-widget. Doesn't work with few widgets

I'm using editable widget (2amigos/yii2-editable-widget or kartik-v/yii2-editable). It works fine, but when I try it in foreach it works with first element only. I want to use a several widgets for a model. How can I solve it?
Here is the code:
foreach ($models as $model) {
echo Editable::widget( [
'model' => $model,
'attribute' => 'name',
'url' => 'site/rename',
'type' => 'text',
'mode' => 'pop',
'clientOptions' => [
' pk' => $model->id,
]
]);
}
I guess you have to set a unique id for each Editable Widget. Look how the js code for the widget is embedded.
e.g. if you use kartiks widget
echo Editable::widget([
'model' => $model,
'attribute' => 'name',
'type' => 'primary',
'size'=> 'lg',
'inputType' => Editable::INPUT_TEXT,
'editableValueOptions' => ['class' => 'text-success h3'],
'options'=> [
'id'=>'name-editable'.uniqid(),
]
]);

yii2 detailview set value with function htmlspecialchars() expects parameter 1 to be string, object given

How to set value for DetailView. I am trying by set value gridview way but that just show error result
This is the code i wrote
<?php echo DetailView::widget([
'model' => $model,
'attributes' => [
'username',
'email',
[ 'label' => 'Nama',
'value' => function($model) { return $model->first_name ." ". $model->last_name; },
],
],
]); ?>
The error is :
htmlspecialchars() expects parameter 1 to be string, object given
In DetailView no need to use function in value property.
<?php echo DetailView::widget([
'model' => $model,
'attributes' => [
'username',
'email',
[ 'label' => 'Name',
'value' => $model->first_name ." ". $model->last_name,
],
],
]); ?>
