Yii2: How to use map() to show two fields in a Select2? - yii2

I am using a Select2 widget for Yii2. It shows a list with the ids of the users.
I need to show two fields defined in my model called Users: first_name_user and last_name_user. Like this:
Daniel Gates
John Connor
John Doe
Maria Key
But I don't know how use map() to show more than one field.
<?= $form
->field($model, 'id_user')
->widget(\common\widgets\Select2::classname(), [
'items' => \yii\helpers\ArrayHelper::map(\app\models\Users::find()->orderBy('name_user')->all(), 'id_user', 'name_user')
])
?>

Model
Add use app\models\Users; and use yii\helpers\ArrayHelper; at top.
public function userList()
{
$userList = [];
$users = Users::find()->orderBy('first_name_user')->all();
$userList = ArrayHelper::map($users, 'id_user', function ($user) {
return $user->first_name_user.' '.$user->last_name_user;
});
return $userList;
}
_form
<?= $form->field($model, 'id_user')->widget(Select2::className(), [
'data' => $model->userList(),
'options' => ['placeholder' => 'Select User'],
]) ?>

You need to use data option instead of items for Select2.
You need to modify your query to show the concatenated first_name_user and last_name_user as an alias and then return it along with the id column to be used in Select2 by ArrayHelper::map().
It's better to add a function to the model you are using to populate the form and return the results from there to the ArrayHelper::map().
Your query should look like
function userList(){
return \app\models\Users::find()
->select([new \yii\db\Expression('[[id_user]],CONCAT([[first_name_user]]," ",[[last_name_user]]) as full_user_name')])
->orderBy('name_user')
->all();
}
Your form field should look like below
<?=
$form->field($model, 'id_user')->widget(Select2::className(), [
'data' => \yii\helpers\ArrayHelper::map($model->userList(), 'id_user', 'full_user_name'),
'options' => [
'placeholder' => 'Select User',
'id' => 'id_user'
],
'theme' => Select2::THEME_DEFAULT,
'pluginOptions' => [
'allowClear' => true
],
]);
?>

Yii2: How to format input number to currency es-AR?

I have a _form.php file with this field:
<?=
$form->field($model, 'price')
->textInput([
'class' => 'form-control',
'type' => 'number'
])
?>
The price has this format 1234.50. I would like to have the format es-AR, like this: 1234,50.
In the GridView of index.php I use this code and it works great so I would like to do the same in the _form but it is not working.
[
'attribute' => 'price',
'value' => function($myModel) {
$myFormat = new NumberFormatter("es-AR", NumberFormatter::CURRENCY);
return $myFormat->formatCurrency($myModel->price, "ARS");
},
]
There are 2 ways to do that:
Add extra class to the price field and use javascript to convert to format you want (remember to return it back on submit)
Create priceFormat() and use it on AfterFind event and remember to use priceUnFormat() to return to decimal on BeforeSave
Use:
$form->field($model, 'attr', ['inputOptions' => ['value' => Yii::$app->formatter->asDecimal($model->attr)]])

Multiple categories in Url

I want to create links something like that:
http://example.com/cat1/itemname-1
http://example.com/cat1/cat2/itemname-2
http://example.com/cat1/cat2/cat3/itemname-3
http://example.com/cat1/cat2/cat3/[..]/cat9/itemname-9
How rule looks like in yii2 UrlManager and how to create links for this?
Url::to([
'param1' => 'cat1',
'param2' => 'cat2',
'param3' => 'cat3',
'slug' => 'itemname',
'id' => 3
]);
Above code is really bad for multiple category params.
I add that important is only last param it means ID.
Controller looks like that:
public function actionProduct($id)
{
echo $id;
}
The below url rule would to this trick but you have to build the "slug" with the categories within your controller:
'rules' => [
['route' => 'module/controller/product', 'pattern' => '<slug:(.*)+>/<id:\d+>', 'encodeParams' => false],
]
Generate the Url:
yii\helpers\Url::toRoute(['/module/controller/product', 'slug' => 'cat1/cat2/cat3', 'id' => 1])
The output would be:
example.com/cat1/cat2/cat3/1

yii2 Kartik-V Typeahead Basic autocomplete on name but store integer value

Updates have been made below
I am trying to use the Kartik-V Typeahead Basic widget with the Yii2 Framework.
The code below is working to display the required data, the user can search via the university name and it appears in the autocomplete list.
The issue is, the model needs to the university id, not the name. Thus the rules are this field can only store an integer and returns a validation error once you select one of the typeahead results.
<?= $form->field($model, 'university_id')->widget(TypeaheadBasic::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'pluginOptions' => ['highlight' => true],
'options' => ['placeholder' => 'Filter as you type ...'],
]); ?>
I am hoping someone can help me understand if there is a setting that needs to be changed so when saving, the user friendly 'uni_name' data is changed back to the uni 'id'.
UPDATE:
I have gotten the code partly working thanks to "Insane Skull".
The new code is:
<?= $form->field($model, 'name')->widget(TypeaheadBasic::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'pluginOptions' => ['highlight' => true],
'options' => ['placeholder' => 'Filter as you type ...', 'id' => 'testID'],
'pluginEvents' => [
'typeahead:select' => new yii\web\JsExpression("function(event, ui) { $('#testing123').val(ui.item.id); }"),
]
]); ?>
<?= Html::activeHiddenInput($model, 'university_id', array ('id' => 'testing123'))?>
Now I am unfortunately getting the error:
Method yii\web\JsExpression::__toString() must return a string value
I would rather use Select2 instead of Typeahead, you are basically trying to implement the functionality that already exists on Select2 but using Typeahead.
<?= $form->field($model, 'university_id')->widget(Select2::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'options' => ['placeholder' => 'Filter as you type ...'],
]); ?>
You can use activeHiddenInput() for this purpose.
Create one public variable in model say name.
Then:
<?= $form->field($model, 'name')->widget(TypeaheadBasic::classname(), [
'data' => ArrayHelper::map(University::find()->all(),'id','uni_name'),
'pluginOptions' => ['highlight' => true],
'options' => ['placeholder' => 'Filter as you type ...'],
'select' => new yii\web\JsExpression("function( event, ui ) {
$('#id_of_hiddenField').val(ui.item.id);
}")
]); ?>
<?= Html::activeHiddenInput($model, 'university_id')?>
And in Controller Get the value of activeHiddenField.

CakePHP 3.0 cannot get 2 items from 1 table

In a football match i have 2 clubs "Home-Club" and "Away-Club" . I have created table "match" and "club" in MySQL. In "match" table has 2 foreign key "home_id" and "away_id". I'm using cakePHP to show list matches, match information contain names of "Home-Club" and "Away-Club". How to get name of "Home-Club" and "Away-Club" in template file ( .ctp file ).
For now I using this code in the template file:
$match->club->name
Code in Controller:
public function index()
{
$this->paginate = [
'contain' => ['Club']
];
$this->set('match', $this->paginate($this->Match));
$this->set('_serialize', ['match']);
}
It always show name of "Away-Club". I don't known how to get name of "Home-Club"
Please tell me how to do it
Thanks very much!
Problem is in definition of belongsTo associations. Try to redefine it this way:
$this->belongsTo('HomeClub', [
'className' => 'Club',
'foreignKey' => 'home_id',
'propertyName' => 'home_club'
]);
$this->belongsTo('AwayClub', [
'className' => 'Club',
'foreignKey' => 'away_id',
'propertyName' => 'away_club'
]);
Names of belongsTo associations have to be unique. Now contain them in the controller
// ...
$this->paginate = [
'contain' => ['HomeClub', 'AwayClub']
];
$this->set('matches', $this->paginate($this->Match));
And then in the template use
<?= $match->home_club->name ?>
<?= $match->away_club->name ?>

Multiple values in one field Yii2

How to display multpiple values in one field.. I Use Select2 Widget. If i use $courses_model[0] it display only one value
Controller
public function actionUpdateteachers($id)
{
$courses_model = ReferenceTeachersCourses::find()->where(['reference_teachers_id' => $id])->all();
.....
}
View
...
<?= $form->field($courses_model[0], 'reference_course_type_id')->widget(Select2::classname(), [
'data' =>ArrayHelper::map($courses,'id','name'),
'options' => ['multiple' => true],
'pluginOptions' => [
'allowClear' => true,
],
]);
...
?>
This widgets works fine - but your $courses_model[0]->reference_course_type_id must have an array of ids as a value if you want to see multiple values selected.
