CodeIgniter 4: How do I display a gallery of image entity objects? - php

Question

I have a site where members can:
upload images
subscribe to other members
like, dislike, and favorite images
view each other's profiles
So in my gallery view, all images are visible with their respective image uploader, likes rating (percentage of likes to dislikes), and date uploaded.
I have created an entity object class called Image that holds all of this information and more. So I am trying to find a way to loop through all the images in the gallery as Image objects. Is that possible?
Here is my Image entity class:
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,
'userViewed' => NULL,
'userFavorited' => NULL,
'userCommented' => NULL,
'userSubscribed' => NULL,
'action' => NULL,

I fill the entity with a function in my ImageModel here:
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;
}
I have tried make a Gallery object class that would hold the images and then fill that object with Image objects but I get the error you cannot keep an array of Entity objects. Is this a logic error or am I going about it all wrong?

Answer 1

I was able to create a multidimensional array of my entity class Image.php and successfully display the necessary information in my view!
I pass the array into my view here in Gallery.php controller:
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);
}
I fill the array and each image object in my model ImageModel.php:
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;
And here is my Image entity class:
class Image extends Entity
{
