ixudra/imageable

Custom Laravel imaging package for the Laravel 5 framework - developed by Ixudra.

The ixudra/imageable package provides an easy to use polymorphic image model that can be linked to one or more models in any Laravel PHP application. The package contains an image model class as well as a factory class that will take care of creating and editing the image model. Additionally, the package will also take care of moving and storing the actual files in the correct locations.

This package can be used by anyone at any given time, but keep in mind that it is optimized for my personal custom workflow. It may not suit your project perfectly and modifications may be in order.

Installation

Pull this package in through Composer:

    {
        "require": {
            "ixudra/imageable": "7.*"
        }
    }

Add the service provider to your config/app.php file:

    'providers'     => array(

        //...
        Ixudra\Imageable\ImageableServiceProvider::class,

    ),

Run package migrations using artisan:

    php artisan migrate --package="ixudra/imageable"

Alternatively, you can also publish the migrations using artisan:

    // Publish all resources from all packages
    php artisan vendor:publish
    
    // Publish only the resources of the package
    php artisan vendor:publish --provider="Ixudra\\Imageable\\ImageableServiceProvider"

Usage

Create a model with a polymorphic relationship to the Image model:

    use Ixudra\Imageable\Models\Image;
    use Ixudra\Imageable\Traits\ImageableTrait;

    class Card extends Eloquent {

        use ImageableTrait;


        protected $imagePath = 'images/cards';


        public function image()
        {
            return $this->morphOne( Image::class, 'imageable' );
        }


        public function delete()
        {
            $this->image->delete();

            parent::delete();
        }

    }

This class must extend the Ixudra\Imageable\Traits\ImageableTrait trait and must have the imagePath property available to it. The imagePath property describes the path to where the images need to be stored on the system. The package uses the public/ directory as the starting point and will append the value of the imagePath value to it in order to derive the full path.

You can create new Image models using the ImageFactory class which is provided in the package. The ImageFactory will take care of creating the Image model, linking the Image to the designated model and moving the uploaded file to the location which is specified in the designated model.

The ImageFactory expects a specific set of input parameters:

• file which holds the actual uploaded file
• alt which holds the name of the image (will be used as alt when displaying the image)
• title which holds the name of the image (will be used as title when displaying the image)

Updating images works similar to creating them. All you need to do is provide the correct information and the ImageFactory will take care of the rest for you. It is also possible to update the image information without actually updating the uploaded file. This can be done by omitting the file attribute from the data that is passed to the factory.

A full example of a factory class that leverages the package functionality can be found in the following example:

    use Ixudra\Imageable\Services\Factories\ImageFactory;

    class CardFactory {

        protected $imageFactory;


        public function __construct(ImageFactory $imageFactory)
        {
            $this->imageFactory = $imageFactory;
        }


        public function create($input, $prefix = '')
        {
            $card = Card::create( array( 'name' => $input['name'] ) );
            $this->imageFactory->make( $input, $card, $prefix );

            return $card;
        }

        public function modify($card, $input, $prefix = '')
        {
            $card = $card->update( array( 'name' => $input['name'] ) );
            $this->imageFactory->modify( $card->image, $input, $card, $prefix );

            return $card;
        }

    }

Finally, the package also provides several views that can be used:

• data.blade.php which includes a Twitter Bootstrap implementation that will allow you to show the image on a page
• fields.blade.php which includes a Twitter Bootstrap implementation that can be included in forms to create and/or modify the image information

Usage example of both cases can be found in the examples below:

    {!! Form::open(array('url' => 'cards', 'method' => 'POST', 'id' => 'createCard', 'class' => 'form-horizontal', 'role' => 'form', 'files' => true)) !!}

        <div class="well well-large">
            <div class='form-group {{ $errors->has('name') ? 'has-error' : '' }}'>
                {!! Form::label('name', 'Name:', array('class' => 'control-label col-lg-3')) !!}
                <div class="col-lg-6">
                    {!! Form::text('name', $input['name'], array('class' => 'form-control')) !!}
                    {!! $errors->first('name', '<span class="help-block">:message</span>') !!}
                </div>
            </div>
        </div>

        @include('imageable::images/fields', array( 'prefix' => 'image_' ))

        <div class="action-button">
            {!! Form::submit('Submit', array('class' => 'btn btn-primary')) !!}
            {!! HTML::linkRoute('cards.index', 'Cancel', array(), array('class' => 'btn btn-default')) !!}
        </div>

    {!! Form::close() !!}

The fields.blade.php file by default assumes two variables:

• $input: associative array of default values of the input fields. Required keys: title, alt
• $requiredFields: array of input fields that the user is required to fill in. If the name of the field is in the array, a required property will be added to the form field, which can then be used to signal this to the user using CSS (not included)

Both of these variables need to be passed to the view in order to use the default views.

    <div class="row">
        <div class="well well-large col-md-12">
            <div class='col-md-10'>
                <div class='col-md-4'>Name:</div>
                <div class='col-md-8'>{{ $card->name }}</div>
            </div>
        </div>
    </div>

    @include('imageable::images/data', array('imageable' => $card))

The usage of these views is by no means required to take advantage of the functionality in this package. However, it is worth noting that both views leverage the functionality of the ixudra/translation package by default. The ixudra/translation package is not included as a requirement for this package, but must be pulled in via composer in order to take advantage of the views which are provided by default.

Planning

• Improve support for multiple images per model
• Add Javascript library to improve user interaction
