CodeIgniter 4：如何显示图像实体对象库？

[英]CodeIgniter 4: How do I display a gallery of image entity objects?

问题描述

我有一个网站，会员可以：

  • 上传图片
  • 订阅其他成员
  • 喜欢、不喜欢和最喜欢的图像
  • 查看彼此的个人资料

因此，在我的图库视图中，所有图像都可以通过其各自的图像上传器、喜欢评级（喜欢到不喜欢的百分比）和上传日期来查看。

我创建了一个名为 Image 的实体对象类，它包含所有这些信息以及更多信息。 所以我试图找到一种方法将画廊中的所有图像作为图像对象循环。 那可能吗？

这是我的图像实体类：

class Image extends Entity
{
    protected $attributes = [
        'viewkey'           => NULL,
        'id'                => NULL,
        'uploader'          => NULL,
        'filename'          => NULL,
        'title'             => NULL,
        'tags'              => NULL,
        'createdAt'         => NULL,
        'modifiedAt'        => NULL,

        }
    }

    /**
     *  Custom __get Methods
     */
    
}

我在这里用我的 ImageModel 中的函数填充实体：

 public function fillImageEntity(string $viewkey)
    {
        $imageData = $this->builder()
            ->where('viewkey', $viewkey)
            ->get()
            ->getRowArray();

        $image = new \App\Entities\Image();

        $image->fill($imageData);
        $image->setDislikeCount($viewkey);
        $image->setLikeCount($viewkey);
        $image->setViewCount($viewkey);
        $image->setFavoriteCount($viewkey);
        $image->setCommentCount($viewkey);
        $image->setRating($viewkey);
        $image->setUserDisliked($viewkey);
        $image->setUserLiked($viewkey);
        $image->setUserViewed($viewkey);
        $image->setUserFavorited($viewkey);
        $image->setUserCommented($viewkey);
        $image->setUserSubscribed($imageData['uploader']);

        return $image;
    }

我尝试创建一个 Gallery 对象类来保存图像，然后用 Image 对象填充该对象，但我收到错误消息，您无法保留 Entity 对象数组。 这是一个逻辑错误还是我做错了？

我能够创建我的实体类 Image.php 的多维数组，并成功地在我的视图中显示必要的信息！

我在 Gallery.php 控制器中将数组传递到我的视图中：

public function index()
    {
        $data = [];
        
        $data = [
            'title'         => 'Image Gallery',
            'gallery'       => $this->imageModel->getEntireGallery(),
        ];

        echo view('templates/header', $data);
        echo view('templates/navigation');
        echo view('templates/filter_bar', $data);
        echo view('images/gallery', $data);
        echo view('templates/footer', $data);
    }

我在我的模型 ImageModel.php 中填充数组和每个图像对象：

public function fillImageEntity(string $viewkey)
    {
        $imageData = $this->builder()
            ->where('viewkey', $viewkey)
            ->get()
            ->getRowArray();

        $image = new \App\Entities\Image();

        $image->fill($imageData);
        $image->setDislikeCount($viewkey);
        $image->setLikeCount($viewkey);
        $image->setViewCount($viewkey);
        $image->setFavoriteCount($viewkey);
        $image->setCommentCount($viewkey);
        $image->setRating($viewkey);
        $image->setUserDisliked($viewkey);
        $image->setUserLiked($viewkey);
        $image->setUserViewed($viewkey);
        $image->setUserFavorited($viewkey);
        $image->setUserCommented($viewkey);
        $image->setUserSubscribed($imageData['uploader']);

        return $image;
    }

    public function getEntireGallery()
    {
        $images = $this->builder()
            ->orderBy('modified_at', 'DESC')
            ->get()
            ->getResultArray();

        foreach ($images as $image) {

            $gallery[$image['id']] = $this->fillImageEntity($image['viewkey']);
        }

        return $gallery;

这是我的图像实体类：

class Image extends Entity
{
    protected $attributes = [
        'viewkey'           => NULL,
        'id'                => NULL,
