Yii2 - 传递表字段以从其他控制器查看

Question

I have this DetailView that renders in a view belonging to ProdutosController some fields (foto, nome, etc.). Inside the detailView is a hyperlink that displays for every recorded showed and when pressed renders a view from EncomendasController, and EncomendasController must show only the name (field nome) of the product in which i activate the 'Comprar' hyperlink.

<?= DetailView::widget([
    'model' => $model,
    'options' => ['class' => 'detail1-galeria-view2'],
    'attributes' => [
        // cria um array com a fotografia, em que carrega a path no campo fieldName da bd
        [
            'attribute'=>'',
            //'value'=>$model->foto,
            'value'=>Html::a(Html::img(Yii::$app->getUrlManager()->getBaseUrl() . "/" .$model->foto, ['width'=>'192', 'height' => "256"]), $model->foto),
            'format' => 'raw',
        ],
        [
        'attribute'=>'',
        'value'=>$model->nome,
        ],
        [
        'attribute'=>'',
        'value'=>$model->categoria,
        ],
        [
        'attribute'=>'',
        'value'=>$model->descricao,
        ],
        [
        'attribute'=>'',
        'value'=>$model->valor.' '.'€',
        ],
        // info
        [
        'attribute'=>'',
        'format' => 'raw',
        'value'=> Html::a(Yii::t('app','Comprar'), Url::toRoute(['encomendas/create'])),
        ],
    ],
]) ?>

How can i pass only the field "nome" from the product detailView in which i pressed the hyperlink button to another view belonging to the other controller named EncomendasController and then show in the new view that same name?

Answer 1

You can pass the controller name followed by controller method as URL and pass 'nome' as attribute. This 'nome' will be redirected to the page.

View

'value'=> Html::a(Yii::t('app','Comprar'), Url::toRoute(['encomendas/create', 'nome' => $model->nome])),

Controller

class EncomendasController 
{
    .
    .
    public function actionCreate($nome) {

        $nome = Yii::$app->request->get('nome');

        return $this->redirect('create',['nome'=>$nome]);

    }
    .
    .

}

create.php (view)

<?php echo $nome;?>
