Yii2类Closure的对象无法转换为字符串

Question

I've got error Object of class Closure could not be converted to string on this code

'class' => \dosamigos\grid\EditableColumn::className(),
            'attribute' => 'remidi3',
            'url' => function($data){return ['update?id=remidi3&dataid'.$data->id];},
            'type' => 'text',
            'editableOptions' => [
                'mode' => 'inline',
            ]

even I've try to change

'url' => function($data){return ['update?id=remidi3&dataid'.$data->id];}

into

'url' => function($data){return 'update?id=remidi3&dataid'.$data->id;},

I need to display id in the URL of editable grid, somebody can help me?

Answer 1

According to source code and PHPDoc, you can't specify closure here.

PHPDoc says:

/**
 * @var string the url to post
 */
 public $url;

Usage in source code:

if ($this->url === null) {
    throw new InvalidConfigException("'Url' property must be specified.");
}

...

$url = (array) $this->url;
$this->options['data-url'] = Url::to($url);

As you can see, it's converted to array and then processed by Url::to(), so the valid types are string and array.

I don't think you need to specify id in url, it should be taken automatically depending on row you working with.
