Yii2 Image Cropper Input Widget for bootstrap 5
Features
This is a wrapper of fengyuanchen/Cropper.js. It provides the following feature:
- Crop
- Image Rotate
- Image Flip
- Image Zoom
- Coordinates
- Image Sizes Info
- Base64 Data
- Set Image.Url Directly
- Set Image.Src With Javascript
Difference from bilginnet/yii2-cropper
This is a fork of bilginnet/yii2-cropper, but it has some important difference:
- Works with bootstrap 5
- Improved UI design of the modal
- Supports the latest version of Cropper.js through composer
- Backward incompatibility
- Doesn't work with bootstrap 3
- Some incompatibility in the options
Installation
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist softark/yii2-cropper-bs5 "dev-master"
or add
"softark/yii2-cropper-bs5": "dev-master"
to the require section of your composer.json
file.
Usage
1) Add aliases for image directory
Add aliases for the directory to store the images in your config file.
$baseUrl = str_replace('/web', '', (new Request)->getBaseUrl()); Yii::setAlias('@imagesUrl', $baseUrl . '/images/'); Yii::setAlias('@imagesPath', realpath(dirname(__FILE__) . '/../images/')); // image file will be stored in //root/images folder return [ .... ]
2) Extend model to handle image data from cropper
Add a virtual attribute for the image data from the cropper widget in your model.
public $_image public function rules() { return [ ['_image', 'safe'], ]; }
And write a function to save the image data from the cropper widget to a file.
public function beforeSave($insert) { if (is_string($this->_image) && strstr($this->_image, 'data:image')) { // creating image file as png, for example // cropper sends image data in a base64 encoded string $data = $this->_image; $data = base64_decode(preg_replace('#^data:image/\w+;base64,#i', '', $data)); $fileName = time() . '-' . rand(100000, 999999) . '.png'; file_put_contents(Yii::getAlias('@imagesPath') . '/' . $fileName, $data); // deleting old image file if any // $this->filename is the real attribute for the filename // customize your code for your attribute if (!$this->isNewRecord && !empty($this->filename)) { @unlink(Yii::getAlias('@imagesPath') . '/' . $this->filename); } // set new filename $this->filename = $fileName; } return parent::beforeSave($insert); }
3) Place cropper in _form file
The following is a typical code that uses the cropper in _form file:
echo $form->field($model, '_image')->widget(\softark\cropper\Cropper::class, [ // Unique ID of the cropper. Will be set automatically if not set. 'uniqueId' => 'image_cropper', // The url of the initial image. // You can set the current image url for update scenario, and // set null for create scenario. // Defaults to null. 'imageUrl' => ($model->isNewRecord) ? null : Yii::getAlias('@imagesUrl') . $model->filename, // Cropper options 'cropperOptions' => [ // The dimensions of the image to be cropped and saved. // You have to specify both width and height. 'width' => 1200, 'height' => 800, // Preview window options 'preview' => [ // The dimensions of the preview image must be specified. 'width' => 600, // you can set as string '100%' 'height' => 400, // you can set as string '100px' // The url of the initial image for the preview. 'url' => (!empty($model->filename)) ? Yii::getAlias('@imagesUrl' . '/' . $model->filename) : null, ], // Whether to use FontAwesome icons 'useFontAwesome' => true, // default = false : use Unicode Chars ], // Modal options 'modalOptions' => [ // Specify the size of the modal. // 'modal-md', 'modal-lg', or 'modal-xl' // Default and recommended value is 'modal-lg' 'modalClass' => 'modal-lg', ], ]);
Options
While many options are supported for the widget, usually you can safely ignore them to accept the default values.
See Options in Detail for reference.
