Yii2: How to use backend web folders files in frontend

问题

I have many images in backends web folder, I want to use those images in frontend how to get those files?

I need to display 1 (first) image which path is saved in database like Img1.jpg;img2.jpg;

    <?php
      foreach (explode(';',rtrim($row['images'],';'),1) as $key_img => $value_img)
 {
  ?>

<?php echo  Html::img('@backend/web'.'/'.$value_img);?>                  

<?php
 }
?>

回答1:

<?= \yii\helpers\Html::img('@backend/web/images/your-image.jpg') ?>

The src parameter, containing the backend alias, will be processed by Url::to()

Check the docs for details on Html::img().

回答2:

Simply try:

<?= \yii\helpers\Html::img( Yii::getAlias('@backend'). '/web/images/your-image.jpg') ?>
