Yii2 Select2 - 업데이트 - 접합 테이블에서 선택된 값

Question

작업 테이블에서 새 행 (사용자 위치)을 성공적으로 삽입하고 작업 업데이트시 성공적으로 업데이트하지만 문제는 ation에서 업데이트됩니다. location_id 필드는 항상 비어 있습니다. 그것은 userlocations 테이블에서 location_id를 가져 와서 업데이트시 필드를 채워야하지만 그렇지 않습니다.

Answer 1

가 선택 아래로 플러그인 코드를 사용합니다.

<?= Select2::widget([ 
     'name' => 'Userlocations[location_id]', 
     'value' => $location_ids, // initial value 
     'data' => ArrayHelper::map(Locations::find()->all(), 'id', 'name'), 
     'options' => ['placeholder' => 'Select your locations...', 'multiple' => true], 
     'pluginOptions' => [ 
      'tags' => true, 
      'maximumInputLength' => 10 
     ], 
    ]); ?> 

$ location_ids 이전에 하나 개 이상의 테이블에 대한 변경을 할 때 당신이 트랜잭션에 그것을 확인, 기억 time.Also 작성시 선택한 위치에 배열 될 것입니다.
