在Yii2中创建拇指

Question

我已经使用这个链接到insatll yii2 2-想象一下：ThumbCreate

当它成功运行时，在/vendor/yiisoft/yii2/Imagine/文件夹中有一个文件夹vendor，然后在该文件夹中又有两个名称为imagine和composer的文件夹。在imagine文件夹中，还有一个同名的文件夹，然后在该文件夹中有那么多文件夹和文件。我正在为那个附加图像。

。

现在，我如何使用缩略图函数来制作图像的缩略图.

composer.json文件

{
    "name": "yiisoft/yii2-imagine",
    "description": "The Imagine integration for the Yii framework",
    "keywords": ["yii2", "imagine", "image", "helper"],

    },

        }
    ],
    "require": {
        "yiisoft/yii2-imagine": "*",
        "imagine/imagine": "0.5.*"
    },
    "autoload": {
        "psr-4": {
            "yii\\imagine\\": ""
        }
    },
    "extra": {
        "branch-alias": {
            "dev-master": "2.0.x-dev"
        }
    }
}

控制器文件

<?php

namespace backend\controllers;

use Yii;
use app\models\Employee;
use yii\web\Controller;
use yii\web\NotFoundHttpException;
use yii\filters\AccessControl;
use yii\filters\VerbFilter;
use yii\web\UploadedFile; // upload the image in folder
use yii\Imagine\Image;
use vendor\ExportXLS; // for export data in excel file

class EmployeeController extends Controller
{
public function actionCreate()
    {
        $model = new Employee();
        $model->added_date_time = date('Y-m-d H:i:s');
        if($model->load(Yii::$app->request->post())) {
            $model->file = UploadedFile::getInstance($model,'avatar');

            if(!empty($model->file)) {
                $imageName = Yii::$app->security->generateRandomString();
                $model->file->saveAs('uploads/emp/'.$imageName.'.'.$model->file->extension);
                $model->avatar = $imageName.'.'.$model->file->extension;
                $originalFile = Yii::$app->basePath.'/uploads/emp/'.$imageName.'.'.$model->file->extension;
                $thumbFile = Yii::$app->basePath.'/uploads/emp/thumb/'.$imageName.'.'.$model->file->extension;

                $saveThumb = Image::thumbnail($originalFile, 200, 200)->save($thumbFile, ['quality' => 80]);
            }
            if($model->save()){
                $this->redirect(\Yii::$app->urlManager->createUrl('employee'));
            }
        }
        else {
            return $this->render('create', [
                'model' =>  $model
                ]);
        }
    }
}
?>

我怎么做拇指？上传图片后。告诉是否需要更多的信息。

Answer 1

1.请从https://github.com/yiisoft/yii2-imagine下载yii2 2-imagine

2.提取高级\供应商\yiisoft\yii2 2中的文件，然后将“yii2 2-imagine”重命名为"imagine“

3.打开advanced\vendor\yiisoft\yii2\classes.php并插入这两行

 'yii\imagine\Image' => YII2_PATH . '/imagine/Image.php',
 'yii\imagine\Image' => YII2_PATH . '/imagine/BaseImage.php',

就像其他行一样。

4.现在请进入前端或后端，打开一个视图或控制器，然后在顶部添加下面的代码

 use yii\imagine\Image;

现在添加了类，然后可以使用Image:：，如下所示。

 Image::thumbnail($filename, $width, $height);

或者其他你想用的方法。

诚挚的问候。
