Upload plugin for CakePHP 3.x
Installation
1. Installing dependency
You can install this plugin into your CakePHP application using composer.
The recommended way to install composer packages is:, (*1)
composer require allanmcarvalho/upload
2. Loading plugin
In App\config\bootstrap.php, (*2)
Plugin::load('Upload', ['bootstrap' => true]);
Basic usage
1 - You should open the table and then add the behavior of the plugin Upload.
// in App\Model\Table\ExamplesTable.php
class ExamplesTable extends Table
{
...
public function initialize(array $config)
{
parent::initialize($config);
$this->addBehavior('Upload.Upload', [
'file1' => [],
'file2' => []
]);
}
...
Note:
Just adding the Upload.Upload Behavior does not mean it's ready, in fact, if you just add, nothing will happen. You must define which table columns are going to be responsible for storing the file name as shown above (file1 and file2)., (*3)
Available Behavior settings
Note: The configuration name must be the same as the table column name. In this example is file1., (*4)
// in App\Model\Table\ExamplesTable.php
$this->addBehavior('Upload.Upload', [
'file1' => [
'path' => WWW_ROOT . 'img' . DS,
'prefix' => 'example_'
]
]);
Options
- path: The path where that file will be saved., (*5)
Note:
When path is not provided, the default is WWW_ROOT . 'files' . DS . $this->table->getAlias() . DS or WWW_ROOT . 'img' . DS . $this->table->getAlias() . DS when the image setting is set., (*6)
-
prefix: A prefix to be added to the image file name. Default: Does not have;
-
image: Set of settings for image uploads;
// in App\Model\Table\ExamplesTable.php
$this->addBehavior('Upload.Upload', [
'file1' => [
'image' => [
'crop' => [
'width' => 600 // Height will be the same
],
'format' => 'png',
'quality' => 75,
'resize' => [
'height' => 750, // width will be automatically calculated
],
'thumbnails' => [
[
'label' => 'thumb1',
'resize' => [
'height' => 750,
],
'watermark' => false // Disables watermark for this item
],
[
'label' => 'thumb2',
'resize' => [
'min_size' => 750,
],
'watermark' => [
'opacity' => 60, // 60% of opacity
'position' => 'top', // center top position
'path' => WWW_ROOT . 'img' . DS . 'watermark2.png',
],
'crop' => [
'width' => 600 // Height will be the same
]
]
],
'watermark' => [
'ignore_default' => true, //do not insert watermark on default
'opacity' => 10, // 10% of opacity
'path' => WWW_ROOT . 'img' . DS . 'watermark.png',
'position' => 'bottom-right'
]
]
]
]);

// in App\Controller\ExampleController.php
...
public function deleteFiles($id)
{
$this->request->allowMethod(['post', 'delete']);
$example = $this->Examples->get($id);
if ($this->Examples->deleteFiles($example)) {
$this->Flash->success(__('The files has been deleted.'));
} else {
$this->Flash->error(__('The files could not be deleted. Please, try again.'));

...
Note: The deleteFiles($entity, $fields = []) method is a table method added by behavior and you can even use inside the table class., (*10)
4 - Validations
There are two types of validators, one to validate information of the files called UploadValidation, and one that after additional features to validate images called ImageValidation. You can also use the two in one by calling DefaultValidation., (*11)
// in App/Model/Table/ExampleTable.php
// Contain files validations
public function validationDefault(Validator $validator)
{
$validator->setProvider('upload', \Upload\Validation\UploadValidation::class);
$validator
->add('file1', 'isUnderPhpSizeLimit', [
'rule' => 'isUnderPhpSizeLimit',
'message' => 'Greater than the PHP size limit',
'provider' => 'upload'
]);
