I have a question here. I set the relations between item and sale tables and now my GridView column of Item name is displaying id's of it. But what I need is that it would display Item names instead of ID's. How should I do that?
Here is my GridView column:
[
'attribute' => 'item_id',
'value' =>
],
I was thinking that I should write a function with if statement, but I have a lot of names and it would be very long. Is there an easier way to solve it?
Assuming your relationship is called getItems(), and the field for the item's name is called name:
[
'attribute' => 'items.name'
],
In my case it is company table and products table.
comp_id is is the primary key in the company table and it has related with products table.
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'prod_id',
'name',
'description:ntext',
[
'attribute' => 'comp_id',
'value' => 'comp.name' //getComp()
],
['class' => 'yii\grid\ActionColumn'],
],
]); ?>
//getcomp function the product model page.
public function getComp()
{`enter code here`
return $this->hasOne(Company::className(), ['comp_id' => 'comp_id']);
}

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
],
]);
?>
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.
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 ?>
<?= $match->away_club->name ?>
How to add a sum column in the gridview?? I have a table with the a grant_amount, and lcc_amount. I want to add grant and lcc and display it in the gridview. How is that done?
I have successfully displayed already the data from the table to the gridview perfectly.
You need set new column and set value, label property like that:
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
...
'grant_amount',
'lcc_amount',
[
'label' => 'Sum',
'value' => function ($model) {
return $model->grant_amount + $model->lcc_amount;
}
],

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.
