Yii2 helper for creating and caching thumbnails on real time.
The preferred way to install this extension is through composer.
- Either run
php composer.phar require "himiklab/yii2-easy-thumbnail-image-helper" "*"
or add
"himiklab/yii2-easy-thumbnail-image-helper" : "*"to the require section of your application's composer.json file.
- Add a new component in
componentssection of your application's configuration file, for example:
'components' => [
'thumbnail' => [
'class' => 'himiklab\thumbnail\EasyThumbnail',
'cacheAlias' => 'assets/gallery_thumbnails',
],
],and in bootstrap section, for example:
'bootstrap' => ['log', 'thumbnail'],It is necessary if you want to set global helper's settings for the application.
For example:
use himiklab\thumbnail\EasyThumbnailImage;
echo EasyThumbnailImage::thumbnailImg(
$model->pictureFile,
50,
50,
EasyThumbnailImage::THUMBNAIL_OUTBOUND,
['alt' => $model->pictureName]
);or
use himiklab\thumbnail\EasyThumbnailImage;
echo EasyThumbnailImage::thumbnailImg(
'http://...',
50,
50,
EasyThumbnailImage::THUMBNAIL_OUTBOUND,
);For other functions please see the source code.
If you want to handle errors that appear while converting to thumbnail by yourself, please make your own class and inherit it from EasyThumbnailImage. In your class replace only protected method errorHandler. For example
class ThumbHelper extends \himiklab\thumbnail\EasyThumbnailImage
{
protected static function errorHandler($error, $filename)
{
if ($error instanceof \himiklab\thumbnail\FileNotFoundException) {
return \yii\helpers\Html::img('@web/images/notfound.png');
} else {
$filename = basename($filename);
return \yii\helpers\Html::a($filename,"@web/files/$filename");
}
}
}
