README

Yiiimages is an images manager for Yii framework 2.0. It stores the files in a separate directory. In models images are saved as paths to files relative to this directory. When images is published their thumbnails are created in an accessible via HTTP location.

Installation

Add package:

#!sh
$ composer require makeitbetter/yiiimages

Configure the application by adding (yii2 guide):

#!php
$config['modules']['yiiimages'] = [
    'class' => 'makeitbetter\yiiimages\Module',
    'options' => [],
];
$config['bootstrap'][] = 'yiiimages';

Available options:

• sourceFolder - Path to folder where the images will be stored. Default: @app/media.
• targetFolder - Path relative to web root where the thumbnails will be putted. Default: thumbnails
• paddingColor - Hexadecimal RGB color to fill thumbnails padding. Default: white, ffffff.
• getThumbnailPathMethod - Function to create thumbnail items path. It should takes Thumbnail object and returns string. By default class's self method will be applied.
• maxUploadNumber - Max number of images available to be uploaded at one time.

Next options define parameters for create thumbnails in the manager page (see more in the description of Class Thumbnail ):

• width - Default: 150.
• height - Default: 150.
• crop - Default: true.
• stretch - Default: false.

Finally, distribute permissions. They should be named: browseImages, addImages, deleteImages.

Usage

In you forms:

#!php
use makeitbetter\yiiimages\widgets\ImageInput;
use yii\widgets\ActiveForm;

$form = ActiveForm::begin();

echo $form->field($model, 'property_name')->widget(ImageInput::className(), $options);

ActiveForm::end();

Or without an ActiveForm object:

#!php
echo ImageInput::widget(['model' => $model, 'attribute' => 'property_name']);

Displaying images:

#!php
use makeitbetter\thumbnail\Thumbnail;

echo Thumbnail::of($model->propery_name, 150, 150)->img()

See more about using a Thumbnail helper in the description of class.

Internationalisation

For adding translations of module strings register a source modules/yiiimages. For example add to your application config file following code:

#!php
$config['components']['i18n'] = [
    'translations' => [
        ...
        'modules*' => [
            'class' => 'yii\i18n\PhpMessageSource',
        ],
    ],
];

This configuration means that the application will search the translations at file @app/messages/xx-XX/modules/yiiimages.php
