Yii2 - Pass variable from view to Gridview custom action columns

Question

I want to save the last place that a user visited before he click onto "Edit" button in the gridview widget of a page. I created a variable named $lastAddress but I really dont know how to pass it onto the gridview and append it to the $url variable of "Edit" button. Can anyone show me how?

$lastAddress = 'xxx';     <?=         GridView::widget([             ...                 [                     'class' => 'yii\grid\ActionColumn',                     'template' => '{view} {update} {delete}',                     'buttons' => [                         'update' => function ($url, $model) {                             $url .= '&lastAddress=' . $lastAddress; //This is where I want to append the $lastAddress variable.                             return Html::a('<span class="glyphicon glyphicon-pencil"></span>', $url);                         },                     ],                 ],             ],         ]);         ?>

Use use to pass in variables from the parent scope to a closure:

'update' => function ($url, $model) use ($lastAddress) {     $url .= '&lastAddress=' . $lastAddress; //This is where I want to append the $lastAddress variable.     return Html::a('<span class="glyphicon glyphicon-pencil"></span>', $url); },
