Question

我想在管理面板中显示图片而不是图片名称。但我在yii 1.1中有很多例子，但在yii 2.0中没有理解使用。这是我的网格视图

   <?php

use yii\helpers\Html;
use yii\grid\GridView;
use yii\imagine\Image;

/* @var $this yii\web\View */
/* @var $dataProvider yii\data\ActiveDataProvider */

$this->title = Yii::t('app', 'Contents');
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="content-index">

    <h1><?= Html::encode($this->title) ?></h1>

    <p>
        <?= Html::a(Yii::t('app', 'Create Content'), ['create'], ['class' => 'btn btn-success']) ?>
    </p>

    <?= GridView::widget([
        'dataProvider' => $dataProvider,
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],

            'id',
            'label',
            'title',
            'content',
        /*  ['attribute' => 'main_image',
                'header' => 'Image',
                'value' => function( $data ) {

                return ?><img src="<?= Yii::$app->request->baseUrl ?>/upload/content/<?php echo $data->main_image?>">
            <?php
           }
           ],*/

                [
                'attribute'=>'photo',
                'value' =>  Html::a(Html::img(Yii::getAlias('@web').'/upload/content'.$content->main_image, ['alt'=>'some', 'class'=>'thing', 'height'=>'100px', 'width'=>'100px']), ['site/zoom']),
                'format' => ['raw'],
                ],



            ['class' => 'yii\grid\ActionColumn'],
        ],
    ]); ?>

</div>

我收到了未定义内容的错误，我也尝试了上面的注释代码。但它在提交的列表中显示“未设置”。

如果对此有任何想法有帮助......

Answer 1

您应该以这种方式格式化您的属性（希望路径正确）

       ['attribute' => 'main_image',
            'header' => 'Image',
            'format' => 'raw',
            'value' => function( $model ) {
                return '<img src="' . echo Yii::$app->request->baseUrl . '/upload/content/'. $model->main_image .'">' ;
       }
    ],

Answer 2

我使用此代码获得解决方案

   ['attribute' => 'main_image',
                    'header' => 'Image',
                    'format' => ['raw'],
                    'value' => function( $data ) {

                    return Html::img(Yii::getAlias('@web').'/upload/content/'.$data->main_image, ['alt'=>'some', 'class'=>'thing', 'height'=>'100px', 'width'=>'100px']);

               }
               ],

图像未显示在yii 2.0的管理员中
