How to get height/width of an image

[vishytk]

I am able to save and retrieve (path, url) of the images but could not figure out how to get the image original height/width while retrieving the image. Db does not seem to save the dimensions of the image. Please help.

here is how I solved this using the spatie/image package (which is a dependency).

width and height are both saved to the DB as custom properties.

    public function store(Request $request)
    {
            [$width, $height] = $this->getDimensions($request->file); // here we get a width/height

            $media = $model->addMediaFromRequest('file')
                ->withCustomProperties($width || $height ? compact('width', 'height') : []) // persist them into DB
                ->toMediaCollection($collectionName);
    }

    private function getDimensions(UploadedFile $file): array
    {
        try {
            $image = Image::load($file->getPathname());

            return [$image->getWidth(), $image->getHeight()];
        } catch (\Throwable $e) {
            return [null, null];
        }
    }

then you can access them anywhere like below:

    $media->getCustomProperty('width');
    $media->getCustomProperty('height');

there is an option also to write dimensions into separate DB table columns.

you have to do the following if you want that:

1. modify your migration which creates the media DB table to add a separate width and height DB columns.

2. do get dimensions while doing upload and save them:

[$width, $height] = $this->getDimensions($request->file); // here we get a width/height

$media = $model->addMediaFromRequest('file')
    ->toMediaCollection($collectionName);

$media->update(['width' => $width, 'height' => $height]);
// or
$media->update(compact('width', 'height'));
// both variations above requires the width & height fields to be 'fillable', or not to be 'guarded'

// or
$media->width = $width;
$media->height = $height;
$media->save();

3. access them later in the code like this:

$media->width;
$media->height;

$isHorizontal = $media->width > $media->height;
