laravel-filecaster

A simple file casting for laravel model to handle file upload and retrieve

---

Installation

composer require sabbir268/laravel-filecaster

Configuration

Cast Class Alias Add in aliases array (optional)

'aliases' => Facade::defaultAliases()->merge([
    // ...
    'filecast' => Sabbir268\LaravelFileCaster\FileCaster::class,
    // ...
])->toArray(),

Publish config file

php artisan vendor:publish --provider="Sabbir268\LaravelFileCaster\FileCasterServiceProvider"

Use from Model

Import FileCaster class

use Sabbir268\LaravelFileCaster\FileCaster;

Example: manage "image" file upload and retrieve

Let's assume, we have Blog model and there is a column image to store image file.

use App\Models;
use Sabbir268\LaravelFileCaster\FileCaster;

class Blog extends Model
{
    // ...
    protected $casts = [
        'image' => FileCaster::class,
    ];
    // ...
}

Or, you can use filecast as alias of Sabbir268\LaravelFileCaster\FileCaster class.

use App\Models;

class Blog extends Model
{
    // ...
    protected $casts = [
        'image' => 'filecast',
    ];
    // ...
}

Now when you will create a new Blog model instance and has a file from request assign to image property, it will automatically upload the file to storage/app/public/{class_name}/{id} directory and store the file name with path in image column.

$blog = new Blog();
$blog->image = $request->file('image');
$blog->save();

And when you will retrieve the model instance, it will automatically retrieve the file path from image column and you can use it as like as a string.

$blog = Blog::find(1);
echo $blog->image; // output: /storage/blog/1/image.jpg

There several methods/property you can use to retrieve the file information.

// get file name
$blog->image->name; // output: image.jpg

// get file extension
$blog->image->extension; // output: jpg

// get file size
$blog->image->size; // output: 1024

// get file mime type
$blog->image->mime; // output: image/jpeg

// get file http url
$blog->image->url; // output: http://example.com/storage/blog/1/image.jpg

// get file full path
$blog->image->path; // output: /var/www/html/storage/app/public/blog/1/image.jpg

// get storage directory
$blog->image->dir; // output: /var/www/html/storage/app/public/blog/1

// check if file exists
$blog->image->exists; // output: true

If you want to get manipulated image url, you can use ur('WIDTHxHEIGHT') method.

$blog->image->url('200x200'); // output: http://example.com/storage/cache/200x200/blog-2-image1.jpg

Note: It will create a manipulated image in storage cache directory. You will need gd or imagick extension installed in your server.

If you want to delete the file, you can use remove() method.

$blog->image->remove(); // output: true
