Array to string conversion error for listData and activeRadioButtonList with $groupField

Yii 1.1 General Discussion

I get Array to string conversion when I use CHtml::listData with $groupField for CHtml::activeRadioButtonList.


$listData = CHtml::listData($data->markets, 'id', 'Market', 'Region_id');

echo CHtml::activeRadioButtonList($data->markets[0], 'id', $listData);

Why doesn’t it work with $groupField?

the reason is you don’t have Primary Key in your tables.

Hi,

It clearly show error… you are trying to pass string in case of array…please check the argument in original method. i think your listdata is not an array …its a guess. check and revert




public static string activeRadioButtonList(CModel $model, string $attribute, array $data, array $htmlOptions=array ( ))

I broke it further down.




public static function tag($tag,$htmlOptions=array(),$content=false,$closeTag=true)

157     {

158         $html='<' . $tag . self::renderAttributes($htmlOptions);

159         if($content===false)

160             return $closeTag && self::$closeSingleTags ? $html.' />' : $html.'>';

161         else

162             return $closeTag ? $html.'>'.$content.'</'.$tag.'>' : $html.'>'.$content;

163     }

it crashes because $content is an array in 162.

The content of $listData with a $groupField parameter turns into


array(2 => array(3 => 'MTN', 4 => 'PNW', 5 => 'NCA'))

It seems like the method in CHtml::activeRadioButtonList() doesn’t process properly the $listData when it’s grouped. Is this a bug in Yii 1.1.15? Is this working for any of you guys and which version do you have?
