Laravel ImageUp

The qcod/laravel-imageup is a trait which gives you auto upload, resize and crop for image feature with tons of customization.

Installation

You can install the package via composer:

$ composer require qcod/laravel-imageup

The package will automatically register itself. In case you need to manually register it you can by adding it in config/app.php providers array:

QCod\ImageUp\ImageUpServiceProvider::class

You can optionally publish the config file with:

php artisan vendor:publish --provider="QCod\ImageUp\ImageUpServiceProvider" --tag="config"

It will create config/imageup.php with all the settings.

Getting Started

To use this trait you just need to add use HasImageUploads on the Eloquent model and define all the fields which needs to store the images in database.

Model

<?php
namespace App;
use QCod\ImageUp\HasImageUploads;
use Illuminate\Database\Eloquent\Model;
class User extends Model {
    use HasImageUploads;
    // assuming `users` table has 'cover', 'avatar' columns
    // mark all the columns as image fields 
    protected static $imageFields = [
        'cover', 'avatar'
    ];
}

Once you marked all the image fields in model it will auto upload the image whenever you save the model by hooking in Model::saved() event.
It will also update the database with new stored file path and if finds old image it will be deleted once new image is uploaded.

Image field should be as as VARCHAR in database table to store the path of uploaded image.

In Controller

<?php
namespace App;
use App\Http\Controllers\Controller;
class UserController extends Controller {
    public function store(Request $request){
        return User::create($request->all());
    }
}

Make sure to run php artisan storage:link to see the images from public storage disk

That’s it, with above setup when ever you hit store method with post request and if cover or avatar named file is present on request() it will be auto uploaded.

Upload Field options

ImageUp gives you tons of customization on how the upload and resize will be handled from defined field options, following are the things you can customize:

<?php
namespace App;
use QCod\ImageUp\HasImageUploads;
use Illuminate\Database\Eloquent\Model;
class User extends Model {
    use HasImageUploads;
    // which disk to use for upload, can be override by field options 
    protected $imagesUploadDisk = 'local';
    // path in disk to use for upload, can be override by field options 
    protected $imagesUploadPath = 'uploads';
    // auto upload allowed 
    protected $autoUploadImages = true;
    // all the images fields for model
    protected static $imageFields = [
        'avatar' => [
            // width to resize image after upload
            'width' => 200,
            // height to resize image after upload
            'height' => 100,
            // set true to crop image with the given width/height and you can also pass arr [x,y] coordinate for crop.
            'crop' => true,
            // what disk you want to upload, default config('imageup.upload_disk')
            'disk' => 'public',
            // a folder path on the above disk, default config('imageup.upload_directory')
            'path' => 'avatars',
            // placeholder image if image field is empty
            'placeholder' => '/images/avatar-placeholder.svg',
            // validation rules when uploading image
            'rules' => 'image|max:2000',
            // override global auto upload setting coming from config('imageup.auto_upload_images')
            'auto_upload' => false,
            // if request file is don't have same name, default will be the field name
            'file_input' => 'photo',
            // if field (here "avatar") don't exist in database or you wan't this field in database
            'update_database' => false,
            // a hook that is triggered before the image is saved
            'before_save' => BlurFilter::class,
            // a hook that is triggered after the image is saved
            'after_save' => CreateWatermarkImage::class
        ],
        'cover' => [
            //...    
        ]
    ];
    // any other than image file type for upload
    protected static $fileFields = [
            'resume' => [
                // what disk you want to upload, default config('imageup.upload_disk')
                'disk' => 'public',
                // a folder path on the above disk, default config('imageup.upload_directory')
                'path' => 'docs',
                // validation rules when uploading file
                'rules' => 'mimes:doc,pdf,docx|max:1000',
                // override global auto upload setting coming from config('imageup.auto_upload_images')
                'auto_upload' => false,
                // if request file is don't have same name, default will be the field name
                'file_input' => 'cv',
                // a hook that is triggered before the file is saved
                'before_save' => HookForBeforeSave::class,
                // a hook that is triggered after the file is saved
                'after_save' => HookForAfterSave::class
            ],
            'cover_letter' => [
                //...    
            ]
        ];
}

Customize filename

In some case you will need to customize the saved filename. By default it will be $file->hashName() generated hash.

You can do it by adding a method on the model with {fieldName}UploadFilePath naming convention:

class User extends Model {
    use HasImageUploads;
    // assuming `users` table has 'cover', 'avatar' columns
    // mark all the columns as image fields 
    protected static $imageFields = [
        'cover', 'avatar'
    ];
    // override cover file name
    protected function coverUploadFilePath($file) {
        return $this->id . '-cover-image.jpg';
    }
}

Above will always save uploaded cover image as uploads/1-cover-image.jpg.

Make sure to return only relative path from override method.

Request file will be passed as $file param in this method, so you can get the extension or original file name etc to build the filename.

    // override cover file name
    protected function coverUploadFilePath($file) {
        return $this->id .'-'. $file->getClientOriginalName();
    }
    /** Some of methods on file */
    // $file->getClientOriginalExtension()
    // $file->getRealPath()
    // $file->getSize()
    // $file->getMimeType()

Available methods

You are not limited to use auto upload image feature only. This trait will give you following methods which you can use to manually upload and resize image.

Note: Make sure you have disabled auto upload by setting protected $autoUploadImages = false;
on model or dynamiclly by calling $model->disableAutoUpload(). You can also disable it for specifig field by calling $model->setImagesField(['cover' => ['auto_upload' => false]);
otherwise you will be not seeing your manual uploads, since it will be overwritten by auto upload upon model save.

$model->uploadImage($imageFile, $field = null) / $model->uploadFile($docFile, $field = null)

Upload image/file for given $field, if $field is null it will upload to first image/file option defined in array.

$user = User::findOrFail($id);
$user->uploadImage(request()->file('cover'), 'cover');
$user->uploadFile(request()->file('resume'), 'resume');

$model->setImagesField($fieldsOptions) / $model->setFilesField($fieldsOptions)

You can also set the image/file fields dynamically by calling $model->setImagesField($fieldsOptions) / $model->setFilesField($fieldsOptions) with field options, it will replace fields defined on model property.

$user = User::findOrFail($id);
$fieldOptions = [
    'cover' => [ 'width' => 1000 ],
    'avatar' => [ 'width' => 120, 'crop' => true ],    
];
// override image fields defined on  model 
$user->setImagesField($fieldOptions);
$fileFieldOption = [
    'resume' => ['path' => 'resumes']
];
// override file fields defined on  model
$user->setFilesField($fileFieldOption);

$model->hasImageField($field) / $model->hasFileField($field)

To check if field is defined as image/file field.

$model->deleteImage($filePath) / $model->deleteFile($filePath)

Delete any image/file if it exists.

$model->resizeImage($imageFile, $fieldOptions)

If you have image already you can call this method to resize it with the same options we have used for image fields.

$user = User::findOrFail($id);
// resize image, it will give you resized image, you need to save it  
$imageFile = '/images/some-big-image.jpg';
$image = $user->resizeImage($imageFile, [ 'width' => 120, 'crop' => true ]);
// or you can use uploaded file
$imageFile = request()->file('avatar');
$image = $user->resizeImage($imageFile, [ 'width' => 120, 'crop' => true ]);

$model->cropTo($x, $y)->resizeImage($imageFile, $field = null)

You can use this cropTo() method to set the x and y coordinates of cropping. It will be very useful if you are getting coordinate from some sort of font-end image cropping library.

$user = User::findOrFail($id);
// uploaded file from request
$imageFile = request()->file('avatar');
// coordinates from request
$coords = request()->only(['crop_x', 'crop_y']);
// resizing will give you intervention image back
$image = $user->cropTo($coords)
    ->resizeImage($imageFile, [ 'width' => 120, 'crop' => true ]);
// or you can do upload and resize like this, it will override field options crop setting
$user->cropTo($coords)
    ->uploadImage(request()->file('cover'), 'avatar');

$model->imageUrl($field) / $model->fileUrl($field)

Gives uploaded file url for given image/file field.

$user = User::findOrFail($id);
// in your view 
<img src="{{ $user->imageUrl('cover') }}" alt="" />
// http://www.example.com/storage/uploads/iGqUEbCPTv7EuqkndE34CNitlJbFhuxEWmgN9JIh.jpeg

$model->imageTag($field, $attribute = ‘’)

It gives you <img /> tag for a field.

{!! $model->imageTag('avatar') !!}
<!-- <img src="http://www.example.com/storage/uploads/iGqUEbCPTv7EuqkndE34CNitlJbFhuxEWmgN9JIh.jpeg" /> -->
{!! $model->imageTag('avatar', 'class="float-left mr-3"') !!}
<!-- <img src="http://www.example.com/storage/uploads/iGqUEbCPTv7EuqkndE34CNitlJbFhuxEWmgN9JIh.jpeg" class="float-left mr-3 /> -->

Hooks

Hooks allow you to apply different type of customizations or any other logic that you want to take place before or after the image is saved.

Definition types

You can define hooks by specifying a class name

protected static $imageFields = [
    'avatar' => [
        'before_save' => BlurFilter::class,
    ],
    'cover' => [
        //...    
    ]
];

The hook class must have a method named handle that will be called when the hook is triggered.
An instance of the intervention image will be passed to the handle method.

class BlurFilter {
    public function handle($image) {
        $image->blur(10);
    }
}

The class based hooks are resolved through laravel ioc container, which allows you to inject any dependencies through the constructor.

Keep in mind you will be getting resized image in before and after save hook handler if you have defined field option with width or height.
Sure you can get original image from request()->file('avatar') any time you want.

The second type off hook definition is callback hooks.

$user->setImagesField([
    'avatar' => [
        'before_save' => function($image) {
            $image->blur(10);
        },
    ],
    'cover' => [
        //...    
    ]
]);

The callback will receive the intervention image instance argument as well.

Hook types

There are two types of hooks a before_save and after_save hooks.

The before_save hook is called just before the image is saved to the disk.
Any changes made to the intervention image instance within the hook will be applied to the output image.

$user->setImagesField([
    'avatar' => [
        'width' => 100,
        'height' => 100,
        'before_save' => function($image) {
            // The image will be 50 * 50, this will override the 100 * 100 
            $image->resize(50, 50);
        },
    ]
]);

The after_save hook is called right after the image was saved to the disk.

$user->setImagesField([
    'logo' => [
        'after_save' => function($image) {
            // Create a watermark image and save it
        },
    ]
]);

Config file

<?php
return [
    /**
     * Default upload storage disk
     */
    'upload_disk' => 'public',
    /**
     * Default Image upload directory on the disc
     * eg. 'uploads' or 'user/avatar'
     */
    'upload_directory' => 'uploads',
    /**
     * Auto upload images from incoming Request if same named field or
     * file_input field on option present upon model update and create.
     * can be override in individual field options
     */
    'auto_upload_images' => true,
    /**
     * It will auto delete images once record is deleted from database
     */
    'auto_delete_images' => true,
    /**
     * Set an image quality
     */
    'resize_image_quality' => 80
];
