Yii2如何使用select2小部件创建表格模板

Question

I have a dropdown list using select2 widget to get the customer contact

$getcontact = ArrayHelper::map(OpContact::find()->all(),'id','code');

 <div class="col-md-10">'.
                     $form->field($model, 'contact_id')->widget(Select2::classname(), [
                          'data' => $getcontact,
                          'language' => 'en',
                          'options' => ['placeholder' => 'Select'],
                          'pluginOptions' => [
                              'allowClear' => true
                          ],                             
                      ])->label(false).' 

For now, its just a normal dropdownlist which show only the contact id.How I can like insert 2nd column for it and put all the data inside a table. For example, I want the dropdown to look like this where I can see the id and the contact name together.

------------------------------
     ID         Contact ID
------------------------------
     21          contact1
     22          contact2
     23          contact3
     24          contact1

Anyone have any idea? Thanks

Answer 1

if you want store only the id and see both id and contactID and contact ID is th concat of id and code you couuld use

$getcontact = ArrayHelper::map(OpContact::find()
               ->select('id, concat(id, code) as contactID')
               ->all(),'id','contactID');

if you want store both you can

$getcontact = ArrayHelper::map(OpContact::find()
               ->select('concat(id, code) as id, concat(id, code) as contactID')
               ->all(),'id','contactID');

您不能全部显示它们，但是您可以在查询（如CONCAT）中以字符串模式合并该字段，或在您的foreach合并字符串中加上“。”

Answer 3

如下更改ArrayHelper 。

$getcontact = ArrayHelper::map(OpContact::find()->all(),'id',function($model){ return $model->id.'-'.$model->code; });
