yii图像不显示

Question

I'm using Yii 2.0 (Advanced Yii 2.0 Application Structure) and I am pretty newbie. Before reading a lot of documentation I think this should be the 'best practised' way of publishing-showing an image.

$path = Yii::$app->basePath.'/views/images';
$assets_url = Yii::$app->assetManager->publish($path).'/';
$video_explicativo = $assets_url."video_explicativo.jpg";
echo "<img id='video_explicativo' src='$video_explicativo' />";

But it doesn't work. Image file is copied successfuly from frontend/views/images/video_explicativo.jpg to frontend/web/assets/81a22c66/video_explicativo.jpg, but $assets_url is returning an array, instead of a string with the URL. So the image doesn't display.

Can you help me with this? I beg you pardon for my poor english. Thank you.

Change your code like below:

$path = Yii::$app->basePath.'/views/images';
$assets_url = Yii::$app->assetManager->publish($path);
$video_explicativo = $assets_url[1].'/'."video_explicativo.jpg";
echo "<img id='video_explicativo' src='$video_explicativo' />";

As, $assets_url is an array which $assets_url[0] is the asset path and $assets_url[1] is the asset url.
