CodeIgniter 4：如何顯示圖像實體對象庫？

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

問題描述

我有一個網站，會員可以：

  • 上傳圖片
  • 訂閱其他成員
  • 喜歡、不喜歡和最喜歡的圖像
  • 查看彼此的個人資料

因此，在我的圖庫視圖中，所有圖像都可以通過其各自的圖像上傳器、喜歡評級（喜歡到不喜歡的百分比）和上傳日期來查看。

我創建了一個名為 Image 的實體對象類，它包含所有這些信息以及更多信息。 所以我試圖找到一種方法將畫廊中的所有圖像作為圖像對象循環。 那可能嗎？

這是我的圖像實體類：

class Image extends Entity
{
    protected $attributes = [
        'viewkey'           => NULL,
        'id'                => NULL,
        'uploader'          => NULL,
        'filename'          => NULL,
        'title'             => NULL,
        'tags'              => NULL,
        'createdAt'         => NULL,
        'modifiedAt'        => NULL,
        'likeCount'         => NULL,
        'dislikeCount'      => NULL,
        'viewCount'         => NULL,
        'favoriteCount'     => NULL,
        'commentCount'      => NULL,
        'rating'            => NULL, 
        'userLiked'         => NULL,
        'userDisliked'      => NULL,

我在這里用我的 ImageModel 中的函數填充實體：

 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;
    }

我嘗試創建一個 Gallery 對象類來保存圖像，然后用 Image 對象填充該對象，但我收到錯誤消息，您無法保留 Entity 對象數組。 這是一個邏輯錯誤還是我做錯了？

我能夠創建我的實體類 Image.php 的多維數組，並成功地在我的視圖中顯示必要的信息！

我在 Gallery.php 控制器中將數組傳遞到我的視圖中：

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 中填充數組和每個圖像對象：

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;

這是我的圖像實體類：

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