echo Select2::widget([

      'name' =&gt; 'topic_id', 


      'model' =&gt; &#036;model,


      'data' =&gt;  ArrayHelper::map(Topics::find()-&gt;orderBy('title')-&gt;asArray()-&gt;all(), 'id', 'title'),


     


      'options' =&gt; [


      'placeholder' =&gt; 'Select Topics ...', 


      'data' =&gt;'&#036;model-&gt;topic_id',


      'class'=&gt;'form-control',

what format you are using to save selected id’s in table ?

nishitech-1 · September 24, 2014, 10:09am

comma separated like 1,2,3

then it should work




echo $form->dropDownList($model, 'surgeonId', $surgeonList, array('prompt' => 'Select', 'multiple' => true, 'selected' => 'selected'));

if you are using as above instead of widget (its worrking for me)

$surgeonList= ArrayHelper::map(Topics::find()->orderBy(‘title’)->asArray()->all(), ‘id’, ‘title’);

echo &#036;form-&gt;field(&#036;model, 'topic_id')-&gt;dropDownList(  &#036;model, 'topic_id', &#036;surgeonList, array('prompt' =&gt; 'Select', 'multiple' =&gt; true, 'selected' =&gt; 'selected'));

m use your code so… display this error

array_merge(): Argument #2 is not an array

nishitech-1 · September 24, 2014, 10:29am

m modify this code showing here…

so error solved

echo $form->field($model, ‘topic_id’)->dropDownList(

 ArrayHelper::map(Topics::find()-&gt;orderBy('title')-&gt;asArray()-&gt;all(), 'id', 'title'),


  ['prompt' =&gt; 'Select topics', 'multiple' =&gt; true, 'selected' =&gt; 'selected']


  


  );

but problem one…

one value selected on edit time when one value is inserted for insert time…

but two or more value are not selected on edit time when two or more values are inserted for insert time.

are you using 2.0 version ? it seems by seeing this




echo $form->field($model, 'topic_id')->dropDownList(

ArrayHelper::map(Topics::find()->orderBy('title')->asArray()->all(), 'id', 'title'),

['prompt' => 'Select topics', 'multiple' => true, 'selected' => 'selected']


);

above I use in 1.1 only

on an other note this should be "attribute" not "name"


<?php

echo Select2::widget([

	// 'name' => 'topic_id', 

	'attribute' => 'topic_id', 

	'model' => $model,

	'data' => ArrayHelper::map(Topics::find()->orderBy('title')->asArray()->all(), 'id', 'title'),


	'options' => [

		'placeholder' => 'Select Topics ...', 

		'data' =>'$model->topic_id',

		'class'=>'form-control', 

		'multiple' => true

	],

]);

?>

Edit time value has been selected,

Super old, but for anyone else, you need to call SomeJunctionTable::deleteAll(['some_junction_id' => $model->id]); Before repopulating with the new ID’s.
