Build Status

Images plugin for CakePHP


Do not use, very early stage

Image upload, management and and manipulation based on

  • josegonzalez/cakephp-upload
  • admad/cakephp-glide
  • fengyuanchen/cropper
  • scottjehl/picturefill


via composer

composer require gintonicweb/images

In config/bootstrap.php

Plugin::load('Images', ['bootstrap' => 'true']);


  1. Add the filename field to the table of your choice.

  2. Add the ImagesBehavior to the Table object of your choice.

class Avatars extends Table
    public function initialize(array $config)
  1. Add the ImageTrait to the matching Entity
use Images\Model\Entity\ImageTrait;

class Avatar extends Entity
    use ImageTrait;

Saving Images

Create a writable /upload folder in the ROOT folder of your app. That's where images will be stored with the following folder structure APP/uploads/Avatars/1234567.jpg.
Then, simply add the field filename to your forms.

echo $this->Form->create('Pictures', ['type' => 'file']);
echo $this->Form->input('filename', ['type' => 'file', 'label' => 'Picture']);
echo $this->Form->end(__('Add'));

Display images

Use the entity's virtual property to create an image of the right dimensions and cache it server-side. The options match The method used to generate urls is the following

    'w' => 300,
    'h' => 400,
    'fit' => 'crop',

It's possible to use that url in your calls to cake's default Html helper.


The most efficient way to display responsive images is via picturefill. This feature is experimental and relies on scottjehl/picturefill and requirejs

<?php $this->loadHelper('Images.Images'); ?>

<?= $this->Images->picturefill($imageEntity, [
    'sizes' => '(min-width: 40em) 80vw, 100vw',
    'srcset' => [375, 480, 780],
    'name' => 'My picture',
    'alt' => 'alt text',
]) ?>

The sizes option represents the fraction of the view-width that the image is supposed to take, and the srcset represents the different images widths that you want to make available. This reduces the data transferred on mobile devices by letting browsers choose the most suited dimensions for the image. for more information, see picturefill

Crop Images

Provide users with a crop and rotate tool. This feature is experimental and currently relies on fengyuanchen/cropper and requirejs and twbs/bootstrap.

Render the following element to benefit from a simple rotate/crop panel

<?= $this->Element('Images.cropbox', [
    'imageUrl' => $entity->getUrl(),
    'height' => '400px',
]) ?>

This form should post the following data back.

    'rotate' => 90,
    'width' => 200,
    'height' => 300,
    'x' => 20,
    'y' => 50,

You can apply it to your Image entity with a controller resemblig this

if ($this->request->is(['post'])) {
    $imagesTable->transform($imageEntity, $this->request->data);
