如何在Yii2 ListView中呈现具有不同视图的项目？

Question

I need to display the news with different views. Now I use this code for a presentation:

 <?= ListView::widget([
                   'dataProvider' => $dataProvider,
                   'itemView' => '_news',
                   'viewParams' => [
                       'fullView' => true,
                       'context' => 'main-page'
                   ]
               ]);
                ?>

My problem is this: The first 3 news show with large images, the other display with small images. Pagination should work necessarily. See this example

Please, help me.

Answer 1

Each item view of List view has a variable called $index which can be used to achieve your desired result. In _news.php you can do the following,

if($index < 3)
    $this->render('_news_big', ['model' => $model]);

else
    $this->render('_news_small', ['model' => $model]);

And have the actual code for the big blocks in _news_big.php and the code for small blocks in _news_small.php .

The other way of doing it is to place the code for both the blocks inside _news.php , (although i don't prefer this method)

if($index < 3)
{
    //Code for big block
}
else
{
    //Code for small blocks
}
